I was installing a library called libelf from sourceforge https://sourceforge.net/projects/elftoolchain/files/Sources/ I installed all the packages listed under the INSTALL file, it seems like the library installed successfully. I attached some of the output below
I used the two lines below to install the library

In fact, any c project that try to compile gives me the same message, for example a basic hello world.c that I compile with gcc -o hello hello.c gives me
ld: unrecognized option -pcollect2: error: ld returned 1 exit status

I'll appreciate any help, thanks
