Can be reproduced both on a glibc 2.31 and glibc 2.38 system with ../src/configure --enable-languages=rust --disable-bootstrap --disable-plugin See GCC_ENABLE_PLUGIN which adjusts 'pluginlibs' but also causes symbols to be exported from the executable. You need to figure what you need. For example the 'jit' frontend also requires this (--enable-host-shared), but IIRC it doesn't require -ldl Some hosts may not support dynamically loading things. -- You are receiving this mail because: You are on the CC list for the bug.

Not sure - --enable-plugin is not about dlopen, it's about exporting all GCCs internal symbols for use by a dlopened shared module. Is the macro processing requiring this or is it rather self-contained? Being able to dlopen() is something different. -- You are receiving this mail because: You are on the CC list for the bug.

I'm not aware of other frontends absolutely requiring dlopen(), but the Modula-2 frontend uses a plugin for some extended diagnostics (but that requires a "real" plugin, with exporting symbols from GCC). I'm not aware of any abstraction for host shared module opening (to cover windows for example), I suppose in the end we need to have such a thing (like libiberty pex_* for execve/wait). Maybe there's functionality in gnulib for this. For now I suggest to look for dlopen(), there's # Some systems need dlopen save_LIBS="$LIBS" LIBS= AC_SEARCH_LIBS(dlopen, dl) DL_LIB="$LIBS" LIBS="$save_LIBS" AC_SUBST(DL_LIB) in gcc/configure.ac, so adding DL_LIB to the crab1 link should possibly suffice. -- You are receiving this mail because: You are on the CC list for the bug.
