I want to use a Linaro toolchain for an imx6 board. The toolchain is hosted on a git repository, and I don't understand how to tell this to buildroot. It seems it looks for a tar.gz file. Anyway I tried to manually git clone the toolchain and I passed the directory of the local repo. When it tries to compile something it returns: checking for arm-buildroot-linux-gnueabi-gcc... /home/marco/dev/buildroot/output/host/usr/bin/arm-fsl-linux-gnueabi-gcc checking whether the C compiler works... no configure: error: in `/home/marco/dev/buildroot/output/build/alsa-lib-1.0.26': the path is correct, but why it looks for "arm-buildroot-linux-gnueabi-gcc"? It seems the internal toolchain! Attached there is my .config file and the buildroot version is: 2014.02-rc2 Thanks!

Did I searched wrong? The external toolchain wrapper is created automatically by buildroot when the toolchain is 'installed'. However, above I see two different paths: /home/marco/dev/fsl-linaro-toolchain/bin/ext-toolchain-wrapper and ~/dev/buildroot/output/host/usr/bin/ Have you moved the buildroot repository to another location? Normally the toolchain wrapper is located in <output>/host/usr/bin, just like the symbolic links that point to it. Best regards, Thomas ^ permalink raw reply [flat|nested] 11+ messages in thread

Best regards, Thomas Thomas, the first path: /home/marco/dev/fsl-linaro-toolchain/fsl-linaro-toolchain/bin is where I put my toolchain. The second one: home/marco/dev/buildroot/output/host/usr/bin/ is where buildroot wrapped the toolchain, but of course /home/marco/dev/fsl-linaro-toolchain/bin/ext-toolchain-wrapper does not exist! I tried to let buildroot to download the tarball but it's the same. In the meanwhile I fix this issue I'm compiling using the built-in codesourcery toolchain.

The toolchain wrapper is not supposed to be called directly like that, but rather always through a symbolic link, like the 'arm-fsl-linux-gnueabi-gcc' one. The wrapper uses the name of the link (how it was called) to know which tool to call in the real toolchain installation. So the behavior you are seeing above is normal. Regarding the usage of a git repo as toolchain: did you try to set the URL as 'git://URL_of_repo/' ? Finally, to understand the cause of the problem you were experiencing: checking for arm-buildroot-linux-gnueabi-gcc... /home/marco/dev/buildroot/output/host/usr/bin/arm-fsl-linux-gnueabi-gcc checking whether the C compiler works... no configure: error: in `/home/marco/dev/buildroot/output/build/alsa-lib-1.0.26' you should look in the 'config.log' file inside /home/marco/dev/buildroot/output/build/alsa-lib-1.0.26. The file may be long, and the error will not be entirely at the end. You should look for the string 'checking whether the C compiler works', and see what the error is that caused the 'no'.

Perhaps this is described in the guide but I didn't find it. About the toolchain git repo I tried to set the URL as 'git://URL_of_repo/' but it asks for a tarball. Anyway I can live with it at the moment... I manually cloned the repository outside buildroot and I passed the path of the toolchain's root directory. Below the relevant part of the config.log. It seems the linker cannot find the libraries. Should I set any environment variables?

Compiling an hello world program with the (symbolic link) in output/host/usr/bin/arm-fsl-linux-gnueabi-gcc leads to the same linker errors described in the previous post. But the original compiler (/home/marco/dev/fsl-linaro-toolchain/bin/arm-fsl-linux-gnueabi-gcc) works fine with the same hello world. Thanks again!

such file or directory) while the real location is: output/host/usr/arm-buildroot-linux-gnueabi/sysroot/usr/lib/crt1.o If I check the original toolchain directly (outside of buildroot):./bin/arm-linux-gcc -print-file-name=crt1.o /home/tdescham/repo/contrib/fsl-linaro-toolchain/bin/../arm-fsl-linux-gnueabi/multi-libs/default/usr/lib/crt1.o So at least the original toolchain can find its crt1.o. Going back to buildroot, here are some variables determined in the external toolchain logic: SYSROOT_DIR=/home/tdescham/repo/contrib/fsl-linaro-toolchain/arm-fsl-linux-gnueabi/multi-libs/default/ ARCH_SYSROOT_DIR=/home/tdescham/repo/contrib/fsl-linaro-toolchain/arm-fsl-linux-gnueabi/multi-libs/armv5/ ARCH_LIB_DIR=lib SUPPORT_LIB_DIR= ARCH_SUBDIR=/home/tdescham/repo/contrib/fsl-linaro-toolchain/arm-fsl-linux-gnueabi/multi-libs/armv5/ During copying of the toolchain files, I do see following message: ln: target '/home/tdescham/repo/contrib/buildroot-toolchain-marco/output/host/usr/arm-buildroot-linux-gnueabi/sysroot//home/tdescham/repo/contrib/fsl-linaro-toolchain/arm-fsl-linux-gnueabi/multi-libs/armv5/' is not a directory: No such file or directory Symlinking /home/tdescham/repo/contrib/buildroot-toolchain-marco/output/host/usr/arm-buildroot-linux-gnueabi/sysroot//home/tdescham/repo/contrib/fsl-linaro-toolchain/arm-fsl-linux-gnueabi/multi-libs/armv5/ -> ./../../../../../../../../../ and this message originates from: toolchain/helpers.mk:158: echo "Symlinking $(STAGING_DIR)/$${ARCH_SUBDIR} -> $${relpath}" ; \ meaning that ARCH_SUBDIR is not supposed to be an absolute path. ARCH_SUBDIR is determined as follows: ARCH_SUBDIR=`echo $${ARCH_SYSROOT_DIR} | sed -r -e "s:^$${SYSROOT_DIR}(.*)/$$:\1:"` which essentially strips off SYSROOT_DIR from the beginning of ARCH_SYSROOT_DIR. However, there is no common part between both variables in this toolchain: SYSROOT_DIR=/home/tdescham/repo/contrib/fsl-linaro-toolchain/arm-fsl-linux-gnueabi/multi-libs/default/ ARCH_SYSROOT_DIR=/home/tdescham/repo/contrib/fsl-linaro-toolchain/arm-fsl-linux-gnueabi/multi-libs/armv5/ so the logic of determining ARCH_SUBDIR is not correct in this case. Looking at the strace output given above, the expected ARCH_SUBDIR is 'armv5'. However, I don't know what is the best way to handle this. One could try to find the greatest common path between SYSROOT_DIR and ARCH_SYSROOT_DIR (/home/tdescham/repo/contrib/fsl-linaro-toolchain/arm-fsl-linux-gnueabi/multi-libs/) and strip that from ARCH_SYSROOT_DIR to get ARCH_SUBDIR, which would fix this use case, but sounds not right. Any input appreciated, Best regards, Thomas ^ permalink raw reply [flat|nested] 11+ messages in thread
