Even if it managed to load libcc1.so (it needs host-dependent name libcc1.dll) then it would soon end up at least on: default_infcall_mmap: error (_("This target does not support inferior memory allocation by mmap.")); As currently there is only: linux-tdep.c: set_gdbarch_infcall_mmap (gdbarch, linux_infcall_mmap); While one could debug Linux targets from MS-Windows host I find it somehow overcomplicated now when we are trying to get it running at least on native Linux x86*. The 'compile' project needs a larger port effort to run on MS-Windows. gdb/ChangeLog 2014-12-17 Jan Kratochvil Fix MinGW compilation. * compile/compile.c (get_compile_file_tempdir): Call error if !HAVE_MKDTEMP. * config.in: Regenerate. * configure: Regenerate. * configure.ac (AC_CHECK_FUNCS): Add mkdtemp. gdb/testsuite/ChangeLog 2014-12-17 Jan Kratochvil Fix MinGW compilation. * gdb.compile/compile-ops.exp: Update untested message if !skip_compile_feature_tests. * gdb.compile/compile-setjmp.exp: Likewise. * gdb.compile/compile-tls.exp: Likewise. * gdb.compile/compile.exp: Likewise. * lib/gdb.exp (skip_compile_feature_tests): Check also "Command not supported on this host". --- diff --git a/gdb/ChangeLog b/gdb/ChangeLog index b672dc3eec5..42ace6de1f6 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,12 @@ +2014-12-17 Jan Kratochvil + + Fix MinGW compilation. + * compile/compile.c (get_compile_file_tempdir): Call error if + !HAVE_MKDTEMP. + * config.in: Regenerate. + * configure: Regenerate. + * configure.ac (AC_CHECK_FUNCS): Add mkdtemp. + 2014-12-17 Doug Evans * valops.c (value_maybe_namespace_elt): Remove redundant call to diff --git a/gdb/compile/compile.c b/gdb/compile/compile.c index 6d3d16ebdfa..414fc35f6c3 100644 --- a/gdb/compile/compile.c +++ b/gdb/compile/compile.c @@ -191,7 +191,11 @@ get_compile_file_tempdir (void) strcpy (tname, TEMPLATE);
