Can't build: undefined reference to `dladdr'

Hello,
I'm trying to build the project but, unfortunately, I receive an error while linking.

Before to start the build process I setup the path to the LLVM installation and the following gcc/g++ variables (the ones I used to build LLVM):

export CC=/usr/bin/gcc-4.8 
export CXX=/usr/bin/g++-4.8

I modified also the `lib/CmakeLists.txt" file to solve a problem with the pthread compilation:

The results of the cmake command is:

Now, when the result of the make command is:

Any idea about what I am doing wrong or how can I solve the problem?

Thanks!

I'm currently using LLVM version 3.5.2.
Do you expect that this version should work?

Thank you very much!

Yes but it didn' help( cmake LLVM_RECOMMEND_VERSION=3.5.2 ..).

I also modified, by hand, the auto-generated build/src/CMakeFiles/llvm-prof.dir/link.txt file by adding the -ldl flag:

/usr/bin/g++-4.8      CMakeFiles/llvm-prof.dir/llvm-prof.cpp.o CMakeFiles/llvm-prof.dir/printer.cpp.o CMakeFiles/llvm-prof.dir/passes.cpp.o  -o llvm-prof  -L/local_disk/cornagli/llvmTracer/llvm3.5Auto/lib -rdynamic -lLLVMAnalysis -lLLVMTarget -lLLVMMC -lLLVMBitReader -lLLVMCore -lLLVMSupport ../lib/libLLVMProfiling.so -pthread -ltinfo -ldl -Wl,-rpath,/local_disk/cornagli/llvmTracer/llvm3.5Auto/lib:/local_disk/cornagli/llvm-prof/llvm-prof/build/lib:

Now the error showed by the make command is:

cmake .. -DLLVM_RECOMMEND_VERSION=3.5

you set VERSION is for lookup llvm-config-3.5

so, there are not llvm-config-3.5.2 at all.

tested ubuntu 16.04.2 just minutes ago
