Ah, that's the problem. > Did you specify a CXX to configure?

It is installed, but configure.ac doesn't call AC_PROG_CXX so it never checks for that tool. Adding AC_PROG_CXX to gltests/configure.ac solves the problem. I see that ansi-c++-opt.m4 may be attempting to do setup a C++ compiler, but it doesn't seem to work when cross-compiling. /Simon
