Can't build: undefined reference to `dladdr'

[acornagl]

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:

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

Thanks!

i test it on LLVM 3.4 and 3.5.

since LLVM has come to 4.0 the code small differ with 3.5

so it can not build out.

if you need. you could try llvm 3.5 version. or try to modify code directly.

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

[xiehuc]

OK，i could try fix compile this weekend。

[acornagl]

Thank you very much!

[xiehuc]

plus，did you use LLVM_RECOMMEND_VERSION compile option？

use ccmake ..

you could see detail

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:

[xiehuc]

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.
