------- Additional Comments From mckinlay at redhat dot com 2005-09-26 22:36 ------- AC_PROG_CXX is, presumably, needed by classpath in order to build the Qt peers. Although this is not the default configuration, it means we can't remove AC_PROG_CXX.
The libjava configure gets around this issue using GCC_NO_EXECUTABLES, which disables linking of configure tests where possible. One solution is to add GCC_NO_EXECUTABLES to the classpath configure. Unfortunatly this introduces a divergance from the upstream configure.ac. We also need to butcher classpath's AC_CHECK_FUNCs because many of these do not work with GCC_NO_EXECUTABLES. However, they are probably not needed anyway because we do not build classpath's JNI code - only the AWT peers. Perhaps the AC_CHECK_FUNCs can be made conditional so as to reduce divergance from upstream? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=24051
