However, I need to also give a function name. Why? Some linkers do not error out if the named library was not found but also not used to satisfy a certain symbol.

If lpx_create_prob is a function in libglpk, that should work. It may be that they used a macro to define it in some header file. Then use a different function that is not implemented as a macro. But the error you are citing from comes most likely from a different test. It is usually better to quote (copy and paste from config.log) error messages, so possible misunderstandings are avoided. > > How can I tell that to autoconf? > > Oh well, this is a quite nice trick. > Checking for main, i.e. > AC_CHECK_LIB(glpk, main) This is not a trick. This is plain broken. There is no need for Autoconf if you are going to disable its primary use anyway. Might as well just set LIBS="-lglpk $LIBS" right away instead of invoking AC_CHECK_LIB.
