[oi-dev] how to determine link directory order for clang

[Carsten Grzemba]

I try to build a package with clang toolchain, but there I have some link troubles:

cmake constructs a link.txt:

/usr/bin/clang++ -m64 -O3 -std=c++11 -O3 -DNDEBUG -stdlib=libc++ -m64 CMakeFiles/iqstat.dir/src/iqstat.cpp.o -o iqstat -L/usr/gcc/6/lib/amd64 -lc++abi -lirods_client -lirods_plugin_dependencies -lirods_common /usr/lib/amd64/libavrocpp.so /usr/lib/amd64/libboost_filesystem.so /usr/lib/amd64/libboost_program_options.so /usr/lib/amd64/libboost_system.so /usr/lib/amd64/libjansson.so /usr/zeromq-4.2/lib/amd64/libzmq.so

which in turn raises:

/usr/bin/clang++ -v -m64 -O3 -std=c++11 -O3 -DNDEBUG -stdlib=libc++ -m64 -stdlib=libc++ CMakeFiles/iqstat.dir/src/iqstat.cpp.o -o iqstat -L/usr/gcc/6/lib/amd64 -lc++abi -lirods_client -lirods_plugin_dependencies -lirods_common /usr/lib/amd64/libavrocpp.so /usr/lib/amd64/libboost_filesystem.so /usr/lib/amd64/libboost_program_options.so /usr/lib/amd64/libboost_system.so /usr/lib/amd64/libjansson.so /usr/zeromq-4.2/lib/amd64/libzmq.so

ld: fatal: file processing errors. No output written to iqstat

The fix is simple: in the argument list have to removed -L/usr/lib/amd64 or it has to put on the end of the -L's list.
But how can I tell it this clang++/cmake
