gcc’s enable “–enable-default-pie” option make you stuck at “relocation R_X86_64_32S against …” error

Recently, after I upgrade gcc on my Arch Linux, I find it has enabled “--enable-default-pie” option by default:

$ gcc -v
Using built-in specs.
COLLECT_GCC=gcc
COLLECT_LTO_WRAPPER=/usr/lib/gcc/x86_64-pc-linux-gnu/7.1.1/lto-wrapper

One consequence of this enhancement is you should rebuild the static libraries which you projects depend on, otherwise you may counter totally confused link errors like this:

relocation R_X86_64_32S against `.text’ can not be used when making a shared object; recompile with -fPIC

A caveat you must pay attention to is if your static library has assembly code object which is not position independent, you must specify “-no-pie” option during link stage of generating final executable binary. This issue let me spend half day to debug, so it is a really good habit to check critical packages’ change log, such as your compiler.

Reference:
PIE.
