5 years ago I have disabled sanitizers by EXTRA_OECMAKE_append = " -DCOMPILER_RT_BUILD_SANITIZERS=OFF" in compiler-rt_git.bb and now compiler-rt is buildable.
But I ran into the problem with libcxx_git.bb It fails on do.configure step. the CMakeError.log contains a lot of errors as follow:
Run Build Command:"/home/alex/temp/poky/build/tmp-glibc/work/armv7ahf-neon-oe-linux-gnueabi/libcxx/5.0.1+gitAUTOINC+1368f4044e_598ae4fa2e_5df6b5da0d_29d1624468-r0/recipe-sysroot-native/usr/bin/ninja" "cmTC_fe993"

ninja: build stopped: subcommand failed.It looks like there is some issue with paths
Could you please direct me on what I have to check to determine the root of the error with libcxx. Thanks!

5 years ago Try adding following in libcxx recipe
DEPENDS_append_class-target = " compiler-rt clang-cross-${TARGET_ARCH} virtual/${MLPREFIX}libc virtual/${TARGET_PREFIX}compilerlibs"
INHIBIT_DEFAULT_DEPS = "1"Unfortunately, it has no effect.
I spent some time and made an experiment. I downloaded clean repos for poky/openembedded/clan/raspberrypi, switched to rocko branch. And was surprised that build was completely successful.
This looks like my yocto has conflicts, but I can't determine what exactly.
Should I provide additional CMake/Yocto Error/LOG files?

5 years ago hmm interesting, if you have logs from bad and good builds for failing package then it would be helpful..

5 years ago Thank you for your support! Here is zip with logs for "bad" and "good" builds of libcxx recipe. libcxx_logs.zip

5 years ago So I see early failures of compiler checks e.g.
--- Performing Test SUPPORTS_VARIADIC_MACROS_FLAG - Failed
+-- Performing Test SUPPORTS_VARIADIC_MACROS_FLAG - SuccessThis means clang compiler was not installed correctly. Perhaps CMakeError.log has more details
as to why it failed.

Hi! I'm trying to build meta-electron which has a dependence on clang. But the build process fails on compiler-rt stage with a message "clang-5.0: error: linker command failed with exit code 1 (use -v to see invocation)"
Target is armv7a Yocto - Rocko meta-clang - Rocko branch
Exact fail from log.do_compile:
Please, give some advice on how to solve this issue.
