Compilation fails due to relocation error

问题

I'm trying to compile ANN. I compiled using the following command,

make linux-g ++

Later when I try to use this in another code, the code is not compiling. I'm getting the following error,

>  relocation R_X86_64_PC32 against symbol `_ZSt4cerr@@GLIBCXX_3.4' can
> not be used when making a shared object; recompile with -fPIC
> /usr/bin/ld: final link failed: Bad value

After going through various questions , I tried adding the following line to CMAKE,

set_target_properties(${LIBRARY_NAME} PROPERTIES POSITION_INDEPENDENT_CODE ON)

but still, it doesn't work. how can I fix this?

回答1:

I'm not sure that this is a proper solution, but as a workaround, you can replace the line

"C++ = g++"

with

"C++ = g++ -fPIC"

in the file Make-config and then recompile.
