First, sorry for not having been able to get back to you earlier. I agree. That AX_SUBMODULE macro is somewhat annoying, it seems the main use of it is so that ISL can get hold of the srcdir for an uninstalled build when it is used in the context of gmp. Now, if I build with --with-gmp-builddir=$$r/$(HOST_SUBDIR)/gmp then it works in my setup. If we suppose that gmp is installed with headers under /some/place/include and libs under /another/place/lib then one could use --with-gmp-prefix=/some/place --with-gmp-exec-prefix=/another/place except that there is a bug in the ISL configure script so it uses gmp-prefix for both include and lib, and this also requires that the include and lib parts of the paths are there. Would it be possible to actually install the libraries somewhere under build and then link against them? /MF
