U-boot build fails - cannot find lgcc / libgcc.a












3















I am using Ubuntu 12.04 LTS 64 bit and trying to create a Linux Image for the SAMA5D36-EK. In doing so I need the mkimage command. According to this website



the mkimage source comes with the U-boot source and is built during U-boot compliation. But I am haivng problems.



Step 1.



I have installed the following:
git 1.7.5, tar 1.2.4, python 2.7.3



I have also done:



$ sudo apt-get install gawk wget git-core diffstat unzip textinfo gcc-multilib build-essentail
$ sudo apt-get install chrpath libsdl1.2-dev xterm autoconf automake libtool libglib2.0-dev
$ sudo apt-get install linux-image-generic linux-headers-generic
$ sudo dpkg –add-architecture i386
$ sudo apt-get update
$ sudo apt-get install libxss1:i386 libxft2:i386


Step 2.



I have installed the cross toolchain according to Yocto ADT Manual sections 3.1/ 3.2 as follows:



$ tar -xjf adt_installer.tar.bz2
$ cd adt_installer
$ gedit adt_installer.conf and set
YOCTOADT_TARGETS=”arm”
YOCTOADT_ROOTFS_arm=”minimal sato-sdk”
YOCTOADT_SYSROOT_IMAGE_arm=”sato-sdk”
(and other arm based settings then save)
$ cd adt-installer
$ ./adt_installer (using the default cross-toolchain location)
$ sudo chmod +x /opt/poky/1.6/envrionment-setup-arm5te-poky-linux-gnueabi
$ sudo /opt/poky/1.6/envrionment-setup-arm5te-poky-linux-gnueabi


The cross development toolchain is now located in
/opt/poky/1.6/sysroots/x86_64-pokysdk-linux/usr/libexec/arm-poky-linux-gnueabi/gcc/arm-poky-linux-gnueabi/4.8.2/



Step 3.



Create U-boot from source



$ git clone git://github.com/linux4sam/u-boot-at91.git
$ cd u-boot-at91
$ make distclean
$ make sama5d3xek_nandflash_config
$ make CROSS_COMPILE=/opt/poky/1.6/sysroots/x86_64-pokysdk-linux/usr/libexec/arm-poky-linux-gnueabi/gcc/arm-poky-linux-gnueabi/4.8.2/


After working for some time it comes with the error: ld: cannot find -lgcc



Step 4.



If I run



$ sudo find /usr/ -name libgcc*


I get the following:



/usr/lib/x86_64-linux-gnu/libgccpp.so.1
/usr/lib/x86_64-linux-gnu/libgccpp.so.1.0.3
/usr/lib/ure/lib/libgcc3_uno.so
/usr/lib/gcc/x86_64-linux-gnu/4.8/libgcc_s_32.so
/usr/lib/gcc/x86_64-linux-gnu/4.8/libgcc_s.so.1
/usr/lib/gcc/x86_64-linux-gnu/4.8/libgcc_eh.a
/usr/lib/gcc/x86_64-linux-gnu/4.8/libgcc_s.so
/usr/lib/gcc/x86_64-linux-gnu/4.8/libgcc_s_x32.so
/usr/lib/gcc/x86_64-linux-gnu/4.8/libgcc.a
/usr/lib/gcc/x86_64-linux-gnu/4.8/32/libgcc_eh.a
/usr/lib/gcc/x86_64-linux-gnu/4.8/32/libgcc_s.so
/usr/lib/gcc/x86_64-linux-gnu/4.8/32/libgcc.a
/usr/lib/gcc/x86_64-linux-gnu/4.8/x32/libgcc_eh.a
/usr/lib/gcc/x86_64-linux-gnu/4.8/x32/libgcc_s.so
/usr/lib/gcc/x86_64-linux-gnu/4.8/x32/libgcc.a
/usr/lib32/libgcc_s.so.1
/usr/share/lintian/overrides/libgcc1
/usr/share/doc/libgcc1
/usr/share/doc/libgcc-4.8-dev
/usr/libx32/libgcc_s.so.1


If I run



$ sudo /sbin/ldconfig -p | grep libgcc*


I get:



libgcrypt.so.11 (libc6,x86-64) => /lib/x86_64-linux-gnu/libgcrypt.so.11
libgcr-ui-3.so.1 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libgcr-ui-3.so.1
libgcr-base-3.so.1 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libgcr-base-3.so.1
libgconf-2.so.4 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libgconf-2.so.4
libgck-1.so.0 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libgck-1.so.0
libgccpp.so.1 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libgccpp.so.1
libgcc_s.so.1 (libc6,x32) => /usr/libx32/libgcc_s.so.1
libgcc_s.so.1 (libc6,x86-64) => /lib/x86_64-linux-gnu/libgcc_s.so.1
libgcc_s.so.1 (libc6) => /lib/i386-linux-gnu/libgcc_s.so.1
libgcc_s.so.1 (libc6) => /usr/lib/gcc/x86_64-linux-gnu/4.8/libgcc_s.so.1
libgcc_s.so.1 (libc6) => /usr/lib32/libgcc_s.so.1
libgcc_s.so (libc6,x32) => /usr/lib/gcc/x86_64-linux-gnu/4.8/x32/libgcc_s.so
libgcc_s.so (libc6,x86-64) => /usr/lib/gcc/x86_64-linux-gnu/4.8/libgcc_s.so
libgcc_s.so (libc6) => /usr/lib/gcc/x86_64-linux-gnu/4.8/32/libgcc_s.so
libgc.so.1 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libgc.so.1


There seems no reference to the two versions of the libgcc.a file that appear in subdirectoris /32/ and /x32/



I then locate the following two files:



/etc/ld.so.conf.d/x86_64-linux-gnu.conf
/opt/poky/1.6/sysroots/x86_64-pokysdk-linux/etc/ld.so.conf


and add the following lines in both files:



/usr/lib/gcc/x86_64-linux-gnu/4.8
/usr/lib/gcc/x86_64-linux-gnu/4.8/32
/usr/lib/gcc/x86_64-linux-gnu/4.8/x32


I now repeat the three 'make' commands from step 3 . It makes about 200 or so files (tools, arch, common, drivers, fs, lib, net, test) but then comes to the same error as follows:



LD      examples/standalone/hello_world
/opt/poky/1.6/sysroots/x86_64-pokysdk-linux/usr/libexec/arm-poky-linux-gnueabi/gcc/arm-poky-linux-gnueabi/4.8.2/ld: cannot find -lgcc
make[2]: *** [examples/standalone/hello_world] Error 1
make[1]: *** [examples/standalone] Error 2
make: *** [examples] Error 2


Step 5.



In the Makefile there is the following entries



# Add GCC lib
ifdef CONFIG_USE_PRIVATE_LIBGCC
ifeq ($(CONFIG_USE_PRIVATE_LIBGCC),y)
PLATFORM_LIBGCC = arch/$(ARCH)/lib/lib.a
else
PLATFORM_LIBGCC = -L $(CONFIG_USE_PRIVATE_LIBGCC) -lgcc
endif
else
PLATFORM_LIBGCC := -L $(shell dirname `$(CC) $(c_flags) -print-libgcc-file-name`) -lgcc
endif


Back in the terminal mode I do the following:



$ CONFIG_USE_PRIVATE_LIBGCC=yes
$ export CONFIG_USE_PRIVATE_LIBGCC


Then rerun the three make commands from Step 3 but get the same error



I then try



$ unset  CONFIG_USE_PRIVATE_LIBGCC


and rerun the three commands but still the error occurs



Then I try



$ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/gcc/x86_64-linux-gnu/4.8:/usr/lib/gcc/x86_64-linux-gnu/4.8/32:/usr/lib/gcc/x86_64-linux-gnu/4.8/x32
$ echo $LD_LIBRARY_PATH
/usr/lib/gcc/x86_64-linux/4.8:/usr/lib/gcc/x86_64-linux-gnu/4.8/32:/usr/lib/gcc/x86_64-linux-gnu/4.8/x32


and run the three make commands, but still an error



Then I try changing the entry in the makefile from:



PLATFORM_LIBGCC := -L $(shell dirname $(CC) $(c_flags) -print-libgcc-file-name) -lgcc



To:



PLATFORM_LIBGCC := -L /usr/lib/gcc/x86_64-linux-gnu/4.8:/usr/lib/gcc/x86_64-linux-gnu/4.8/32:/usr/lib/gcc/x86_64-linux-gnu/4.8/x32 -lgcc


I save the file.
Back in the terminal mode I do the following:



$ CONFIG_USE_PRIVATE_LIBGCC=yes
$ export CONFIG_USE_PRIVATE_LIBGCC


Then rerun the three make commands from Step 3 but get the same error



I then try



$ unset  CONFIG_USE_PRIVATE_LIBGCC


and rerun the three commands but still the error occurs



I then change the Makefile entry to:



PLATFORM_LIBGCC :=/usr/lib/gcc/x86_64-linux-gnu/4.8/32/libgcc.a


which finally gets past the -lgcc error associated with the hello_world example, but then fails a little further on with hundreds of failures starting with:



LD      u-boot
arch/arm/cpu/armv7/at91/built-in.o: In function `at91_pll_rate':

etc



I then change the Makefile entry to:



PLATFORM_LIBGCC :=/usr/lib/gcc/x86_64-linux-gnu/4.8/x32/libgcc.a


and the same result occurs as immeditly described above



Can anyone suggest how to fix this problem?

      I am using Ubuntu 12.04 LTS 64 bit and trying to create a Linux Image for the SAMA5D36-EK. In doing so I need the mkimage command. According to this website



      the mkimage source comes with the U-boot source and is built during U-boot compliation. But I am haivng problems.



      Step 1.



      I have installed the following:
      git 1.7.5, tar 1.2.4, python 2.7.3



      I have also done:



      $ sudo apt-get install gawk wget git-core diffstat unzip textinfo gcc-multilib build-essentail
      $ sudo apt-get install chrpath libsdl1.2-dev xterm autoconf automake libtool libglib2.0-dev
      $ sudo apt-get install linux-image-generic linux-headers-generic
      $ sudo dpkg –add-architecture i386
      $ sudo apt-get update
      $ sudo apt-get install libxss1:i386 libxft2:i386


      Step 2.



      I have installed the cross toolchain according to Yocto ADT Manual sections 3.1/ 3.2 as follows:



      $ tar -xjf adt_installer.tar.bz2
      $ cd adt_installer
      $ gedit adt_installer.conf and set
      YOCTOADT_TARGETS=”arm”
      YOCTOADT_ROOTFS_arm=”minimal sato-sdk”
      YOCTOADT_SYSROOT_IMAGE_arm=”sato-sdk”
      (and other arm based settings then save)
      $ cd adt-installer
      $ ./adt_installer (using the default cross-toolchain location)
      $ sudo chmod +x /opt/poky/1.6/envrionment-setup-arm5te-poky-linux-gnueabi
      $ sudo /opt/poky/1.6/envrionment-setup-arm5te-poky-linux-gnueabi


      The cross development toolchain is now located in
      /opt/poky/1.6/sysroots/x86_64-pokysdk-linux/usr/libexec/arm-poky-linux-gnueabi/gcc/arm-poky-linux-gnueabi/4.8.2/



      Step 3.



      Create U-boot from source



      $ git clone git://github.com/linux4sam/u-boot-at91.git
      $ cd u-boot-at91
      $ make distclean
      $ make sama5d3xek_nandflash_config
      $ make CROSS_COMPILE=/opt/poky/1.6/sysroots/x86_64-pokysdk-linux/usr/libexec/arm-poky-linux-gnueabi/gcc/arm-poky-linux-gnueabi/4.8.2/


      After working for some time it comes with the error: ld: cannot find -lgcc



      Step 4.



      If I run



      $ sudo find /usr/ -name libgcc*


      I get the following:



      /usr/lib/x86_64-linux-gnu/libgccpp.so.1
      /usr/lib/x86_64-linux-gnu/libgccpp.so.1.0.3
      /usr/lib/ure/lib/libgcc3_uno.so
      /usr/lib/gcc/x86_64-linux-gnu/4.8/libgcc_s_32.so
      /usr/lib/gcc/x86_64-linux-gnu/4.8/libgcc_s.so.1
      /usr/lib/gcc/x86_64-linux-gnu/4.8/libgcc_eh.a
      /usr/lib/gcc/x86_64-linux-gnu/4.8/libgcc_s.so
      /usr/lib/gcc/x86_64-linux-gnu/4.8/libgcc_s_x32.so
      /usr/lib/gcc/x86_64-linux-gnu/4.8/libgcc.a
      /usr/lib/gcc/x86_64-linux-gnu/4.8/32/libgcc_eh.a
      /usr/lib/gcc/x86_64-linux-gnu/4.8/32/libgcc_s.so
      /usr/lib/gcc/x86_64-linux-gnu/4.8/32/libgcc.a
      /usr/lib/gcc/x86_64-linux-gnu/4.8/x32/libgcc_eh.a
      /usr/lib/gcc/x86_64-linux-gnu/4.8/x32/libgcc_s.so
      /usr/lib/gcc/x86_64-linux-gnu/4.8/x32/libgcc.a
      /usr/lib32/libgcc_s.so.1
      /usr/share/lintian/overrides/libgcc1
      /usr/share/doc/libgcc1
      /usr/share/doc/libgcc-4.8-dev
      /usr/libx32/libgcc_s.so.1


      If I run



      $ sudo /sbin/ldconfig -p | grep libgcc*


      I get:



      libgcrypt.so.11 (libc6,x86-64) => /lib/x86_64-linux-gnu/libgcrypt.so.11
      libgcr-ui-3.so.1 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libgcr-ui-3.so.1

      libgcc_s.so.1 (libc6) => /lib/i386-linux-gnu/libgcc_s.so.1
      libgcc_s.so.1 (libc6) => /usr/lib/gcc/x86_64-linux-gnu/4.8/libgcc_s.so.1
      libgcc_s.so.1 (libc6) => /usr/lib32/libgcc_s.so.1
      libgcc_s.so (libc6,x32) => /usr/lib/gcc/x86_64-linux-gnu/4.8/x32/libgcc_s.so
      libgcc_s.so (libc6,x86-64) => /usr/lib/gcc/x86_64-linux-gnu/4.8/libgcc_s.so
      libgcc_s.so (libc6) => /usr/lib/gcc/x86_64-linux-gnu/4.8/32/libgcc_s.so
      libgc.so.1 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libgc.so.1


      There seems no reference to the two versions of the libgcc.a file that appear in subdirectoris /32/ and /x32/



      I then locate the following two files:



      /etc/ld.so.conf.d/x86_64-linux-gnu.conf
      /opt/poky/1.6/sysroots/x86_64-pokysdk-linux/etc/ld.so.conf


      and add the following lines in both files:



      /usr/lib/gcc/x86_64-linux-gnu/4.8
      /usr/lib/gcc/x86_64-linux-gnu/4.8/32
      /usr/lib/gcc/x86_64-linux-gnu/4.8/x32


      I now repeat the three 'make' commands from step 3 . It makes about 200 or so files (tools, arch, common, drivers, fs, lib, net, test) but then comes to the same error as follows:



      LD      examples/standalone/hello_world
      /opt/poky/1.6/sysroots/x86_64-pokysdk-linux/usr/libexec/arm-poky-linux-gnueabi/gcc/arm-poky-linux-gnueabi/4.8.2/ld: cannot find -lgcc
      make[2]: *** [examples/standalone/hello_world] Error 1
      make[1]: *** [examples/standalone] Error 2
      make: *** [examples] Error 2


      Step 5.



      In the Makefile there is the following entries



      # Add GCC lib
      ifdef CONFIG_USE_PRIVATE_LIBGCC
      ifeq ($(CONFIG_USE_PRIVATE_LIBGCC),y)
      PLATFORM_LIBGCC = arch/$(ARCH)/lib/lib.a
      else
      PLATFORM_LIBGCC = -L $(CONFIG_USE_PRIVATE_LIBGCC) -lgcc
      endif
      else
      PLATFORM_LIBGCC := -L $(shell dirname `$(CC) $(c_flags) -print-libgcc-file-name`) -lgcc
      endif


      Back in the terminal mode I do the following:



      $ CONFIG_USE_PRIVATE_LIBGCC=yes
      $ export CONFIG_USE_PRIVATE_LIBGCC


      Then rerun the three make commands from Step 3 but get the same error



      I then try



      $ unset  CONFIG_USE_PRIVATE_LIBGCC


      and rerun the three commands but still the error occurs



      Then I try



      $ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/gcc/x86_64-linux-gnu/4.8:/usr/lib/gcc/x86_64-linux-gnu/4.8/32:/usr/lib/gcc/x86_64-linux-gnu/4.8/x32
      $ echo $LD_LIBRARY_PATH
      /usr/lib/gcc/x86_64-linux/4.8:/usr/lib/gcc/x86_64-linux-gnu/4.8/32:/usr/lib/gcc/x86_64-linux-gnu/4.8/x32


      and run the three make commands, but still an error



      Then I try changing the entry in the makefile from:



      PLATFORM_LIBGCC := -L $(shell dirname $(CC) $(c_flags) -print-libgcc-file-name) -lgcc



      To:



      PLATFORM_LIBGCC := -L /usr/lib/gcc/x86_64-linux-gnu/4.8:/usr/lib/gcc/x86_64-linux-gnu/4.8/32:/usr/lib/gcc/x86_64-linux-gnu/4.8/x32 -lgcc


      I save the file.
      Back in the terminal mode I do the following:



      $ CONFIG_USE_PRIVATE_LIBGCC=yes
      $ export CONFIG_USE_PRIVATE_LIBGCC


      Then rerun the three make commands from Step 3 but get the same error



      I then try



      $ unset  CONFIG_USE_PRIVATE_LIBGCC


      and rerun the three commands but still the error occurs



      I then change the Makefile entry to:



      PLATFORM_LIBGCC :=/usr/lib/gcc/x86_64-linux-gnu/4.8/32/libgcc.a


      which finally gets past the -lgcc error associated with the hello_world example, but then fails a little further on with hundreds of failures starting with:



      LD      u-boot
      arch/arm/cpu/armv7/at91/built-in.o: In function `at91_pll_rate':

      /home/lachlan/u-boot-at91/common/cmd_sf.c:237: undefined reference to `__aeabi_uidivmod'


      etc



      I then change the Makefile entry to:



      PLATFORM_LIBGCC :=/usr/lib/gcc/x86_64-linux-gnu/4.8/x32/libgcc.a


      and the same result occurs as immeditly described above



      Can anyone suggest how to fix this problem?

      $ export CONFIG_USE_PRIVATE_LIBGCC


      Then rerun the three make commands from Step 3 but get the same error



      I then try



      $ unset  CONFIG_USE_PRIVATE_LIBGCC


      and rerun the three commands but still the error occurs



      I then change the Makefile entry to:



      PLATFORM_LIBGCC :=/usr/lib/gcc/x86_64-linux-gnu/4.8/32/libgcc.a


      which finally gets past the -lgcc error associated with the hello_world example, but then fails a little further on with hundreds of failures starting with:



      LD      u-boot
      arch/arm/cpu/armv7/at91/built-in.o: In function `at91_pll_rate':

      /home/lachlan/u-boot-at91/common/cmd_sf.c:237: undefined reference to `__aeabi_uidivmod'


      etc



      I then change the Makefile entry to:



      PLATFORM_LIBGCC :=/usr/lib/gcc/x86_64-linux-gnu/4.8/x32/libgcc.a


      and the same result occurs as immeditly described above



      Can anyone suggest how to fix this problem?







      gcc ld

          In some Makefiles it tries to find the search path for libgcc by executing:



          $(CC) -print-libgcc-file-name


          This fails if no sysroot is defined, so add sysroot manually. Have a look at the config.mk where it says:



          CC := $(CROSS_COMPILE)gcc


          Change it to:



          ifdef PKG_CONFIG_SYSROOT_DIR
          CC = $(CROSS_COMPILE)gcc --sysroot=$(PKG_CONFIG_SYSROOT_DIR)
          else
          CC = $(CROSS_COMPILE)gcc
          endif

            change cross_compile to another directory, for 4.1.15



            source /<dir>/environment-setup-cortexa9hf-neon-poky-linux-gnueabi
