Fedora 28: clang++ is not used by cmake, and c++ is not working #484

Open Dav1d23 opened 6 years ago

Dav1d23 commented 6 years ago

I had an issue compiling the irony-server on fedora 28 with clang6.

Basically, this command is not working at first.

cmake --clean-first -DCMAKE_INSTALL_PREFIX\=~/.emacs.d/irony/ -DCMAKE_VERBOSE_MAKEFILE:BOOL=ON ~/.emacs.d/elpa/irony-20180519.422/server && cmake --build . --use-stderr --config Release --target install

First issue: CLANG_RESOURCE_DIR is not detected, so you should force it using -DCLANG_RESOURCE_DIR=/usr/lib64/clang/6.0.0/

Then, compilation is not working fine. bB debugging the command line, I saw that c++ was used instead of clang++. Just running this line in the cmake folder $ clang++ -fno-exceptions -O2 -DNDEBUG -rdynamic CMakeFiles/irony-server.dir/support/CommandLineParser.cpp.o CMakeFiles/irony-server.dir/support/TemporaryFile.cpp.o CMakeFiles/irony-server.dir/Command.cpp.o CMakeFiles/irony-server.dir/Irony.cpp.o CMakeFiles/irony-server.dir/TUManager.cpp.o CMakeFiles/irony-server.dir/main.cpp.o -o ../bin/irony-server -lclang and re-running the whole cmake install target above solved the issue.

Is it normal? Am I missing anything? Is there anything that can be done to avoid this situation?

This does not look normal.

Can you show the output of a simple invocation like:

mkdir build
cd build
cmake ../server

This is what I got.
