------- Comment #2 from rob1weld at aol dot com 2009-02-23 03:51 ------- Rainer, while we wait for the patch did you wish to try this: 1. Edit the gcc/configure (Line 9562) and reverse the detection order: - for ac_header in gelf.h libelf/gelf.h + for ac_header in libelf/gelf.h gelf.h 2. Edit lto_plugin/lto_plugin.c and lto_plugin/lto-symtab.c and both add in ../gcc/auto-host.h and change the define testing order: #undef PACKAGE_NAME #undef PACKAGE_STRING #undef PACKAGE_TARNAME #undef PACKAGE_VERSION #include "../gcc/auto-host.h" #ifdef __COMMENT__ #ifdef HAVE_GELF_H # include #else # if defined(HAVE_LIBELF_GELF_H) # include # else # error "gelf.h not available" # endif #endif #endif /* __COMMENT__ */ #if defined(HAVE_LIBELF_GELF_H) # include #else # ifdef HAVE_GELF_H # include # else # error "gelf.h not available" # endif #endif You can hand-compile to fix the 'Werror" that will remain: cc1: warnings being treated as errors ../../lto_trunk/lto-plugin/lto-plugin.c: In function ‘onload’: ../../lto_trunk/lto-plugin/lto-plugin.c:670: error: implicit declaration of function ‘mkdtemp’ ../../lto_trunk/lto-plugin/lto-plugin.c:670: error: assignment makes pointer from integer without a cast gmake[3]: *** [lto-plugin.lo] Error 1 That fixes it for me.
