The no-executables.at test group nicely shows which cache variables need to be set inside the configury of GCC when GCC_NO_EXECUTABLES is in use; unfortunately, I don't know of an easy way for GCC to determine how to set them reliably when the linker cannot be used. While the dlopen-related ones may be implied fairly reliably from $host, the rest is simply unclear to me. See e.g. this PR for an instance of the problem: <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45174#c13> Thanks, Ralf Fix AC_NO_EXECUTABLES test failure on AIX. * libltdl/m4/libtool.m4 (_LT_SYS_MODULE_PATH_AIX): Wrap link test in AC_CACHE_VAL, using cache variable $lt_cv_aix_libpath. * tests/no-executables.at (AC_NO_EXECUTABLES): Preset it, to avoid link test.
