check-symbol failure on Nix base toolchain #619
Description
Hey folks,
How reliable is the check-symbols target? I have a slightly modified (only added WebAssembly backend to llvm) clang based toolchain in nix, and I'm compiling wasi-lib like this:
TARGET_TRIPLE=wasm32-wasi bash scripts/install-include-headers.sh
make CC=${llvmPackages_latest.clang-unwrapped}/bin/clang-$clang_version \
SYSROOT=$SYSROOT \
SYSROOT_LIB=$SYSROOT_LIB \
SYSROOT_INC=$SYSROOT_INC \
SYSROOT_SHARE=$SYSROOT_SHARE \
AR="${llvmPackages_latest.libllvm}/bin/llvm-ar" \
NM="${llvmPackages_latest.libllvm}/bin/llvm-nm" \
EXTRA_CFLAGS="-isystem ${llvmPackages_latest.clang-unwrapped.lib}/lib/clang/$clang_version/include"
But at the very last step of the compilation the diff command in check-symbols fails and returns a diff which is like:
