[llvm-dev] [Support][Debuginfod] Can't find curl/curl.h include...

Mon Dec 6 13:09:17 PST 2021

I'm using clang version 12.0.0 (https://github.com/llvm/llvm-project.git 7fef551cb123d9f1956f8ec7a142bd8a63d25fa9)

With "pkg info | grep cmake":
cmake-3.8.2                    Cross-platform Makefile generator
cmake-modules-3.8.2            Modules and Templates for CMake

I have a script that runs:

exec cmake -G Ninja \
   -DLLVM_PARALLEL_LINK_JOBS=10 \
   -DCMAKE_INSTALL_PREFIX=$HOME2/llvm-trunk/b64nd \
   -DCMAKE_BUILD_TYPE=Debug \
   -DLLVM_ENABLE_ASSERTIONS=On \
   -DCMAKE_AR=/usr/local/bin/ar \
   -DCMAKE_NM=/usr/local/bin/nm \
   -DCMAKE_STRIP=/usr/local/bin/strip \
   -DCMAKE_RANLIB=/usr/local/bin/ranlib \
   -DCMAKE_OBJCOPY=/usr/local/bin/objcopy \
   -DCMAKE_OBJDUMP=/usr/local/bin/objdump \
   -DLLVM_ENABLE_PROJECTS="clang" \
   -DCMAKE_C_COMPILER=$HOME2/llvm-trunk/b64nd/bin/clang \
   -DCMAKE_CXX_COMPILER=$HOME2/llvm-trunk/b64nd/bin/clang++ \
   -DCMAKE_LINKER=/usr/local/bin/ld \
   -DLLVM_ENABLE_SPHINX=on \
   -DLLVM_ENABLE_EXPENSIVE_CHECKS=on \
   $HOME2/clvm/trunk/llvm-earlycse/llvm

I was incorrect earlier in that I'm not using the base FreeBSD clang. My mistake.

My git tree is current as of:

Hi Kevin,

Could you please share your complete Cmake configuration invocation? E.g. `cmake -S llvm -B build -G Ninja -D...`

Thanks,
Noah

I've got a build failure now that we're using curl. I'm on FreeBSD 11.1 using its clang.

What I'm seeing is that during the configure stage this gets printed:
-- Found CURL: /usr/local/lib/libcurl.so (found version "7.54.1")

But the curl/curl.h include file is located in /usr/local/include which is _not_ in the list of paths FreeBSD's clang checks by default. The result is a failure to find the include.

I don't know what the right solution is and I don't know cmake. Perhaps making sure that "/usr/local/lib/../include" gets a "-I" flag to the clang build since that /lib/ directory is where libcurl.so was found?
