I'm trying to build a project that depends on binary distributed static libraries.

The linker complains it cannot find ini_config functions, among others: 

config_params.c:(.text+0x16f): undefined reference to  `ini_get_config_valueobj'

It finds the dynamic libraries, but not the static version:

attempt to open /usr/lib/gcc/x86_64-linux-gnu/7/libini_config.a failed
attempt to open /usr/lib/gcc/x86_64-linux-gnu/7/../../../x86_64-linux-gnu/libini_config.so succeeded

Those files are present on debian stretch. Is there a way to get them on ubuntu as well ?

All packages seem to install their static libraries. They can be found in /usr/lib/x86_64-linux-gnu.

Apparently, the linker first picks the dynamic libraries when using -lsomelib. To override that, you can use the -l:libsomelib.a, it will then only match the exact filename somelib.a. Use -L/usr/lib/x86_64-linux-gnu the same way as for "linking" dynamic libraries.

To debug the library searching phase, you can add -Wl, --verbose to your LDFLAGS. gcc will then display every path it tries for your -lXXX options.

Keep in mind that archives are checked only once, as stated in this answer, if some symbols are still not found, you maybe have to reorder the parameters.
