MinGW (http://www.mingw.org/) now has an official 4.4.0 release - and thus finally a 4.x release. If one looks at the release, http://sourceforge.net/project/showfiles.php?group_id=2435&package_id=241304 one finds a tar ball (gcc-4.4.0-mingw32-src-2.tar.gz) with patches.
For Fortran, I found the following; we should consider applying them - after understanding whether the changes make sense. There are two changes: a) -no-undefined b) LIBOBJDIR= * * * a) -no-undefined option For MinGW the "-no-undefined" is set, cf. http://www.gnu.org/software/libtool/manual/html_node/libtool-script-contents.html#index-allow_005fundefined_005fflag-358 and more readable: http://lists.gnupg.org/pipermail/gcrypt-devel/2006-June/000966.html Doing a grep shows that it is already set for libgomp/Makefile.in and libssp/Makefile.in. MinGW sets is additionally for libgfortran, libffi, libjava, libobjc, libstdc++v3/{,lib*/}. b) LIBOBJDIR= See: http://www.gnu.org/software/autoconf/manual/html_node/AC_005fLIBOBJ-vs-LIBOBJS.html. I think this part of the patch is a side effect of using autoconf 1.10+ instead of autoconf 1.9.6, which is suggested for GCC development. Note: An analogous patch was accepted for libgomp by a build-machinery maintainer, http://gcc.gnu.org/ml/gcc-patches/2008-08/msg01509.html --------------------------------------------------------------------------- Index: libgfortran/Makefile.am =================================================================== --- libgfortran/Makefile.am (revision 145042) +++ libgfortran/Makefile.am (working copy) @@ -17,7 +17,9 @@ LTLDFLAGS = $(shell $(SHELL) $(top_srcdi toolexeclib_LTLIBRARIES = libgfortran.la libgfortran_la_LINK = $(LINK) -libgfortran_la_LDFLAGS = -version-info `grep -v '^\#' $(srcdir)/libtool-version` $(LTLDFLAGS) -lm $(extra_ldflags_libgfortran) $(version_arg) +libgfortran_la_LDFLAGS = -version-info `grep -v '^\#' $(srcdir)/libtool-version` \ + $(LTLDFLAGS) -lm $(extra_ldflags_libgfortran) \ + $(version_arg) -no-undefined myexeclib_LTLIBRARIES = libgfortranbegin.la myexeclibdir = $(libdir)/gcc/$(target_alias)/$(gcc_version)$(MULTISUBDIR) Index: libgfortran/Makefile.in =================================================================== --- libgfortran/Makefile.in (revision 146010) +++ libgfortran/Makefile.in (working copy) @@ -37,6 +37,7 @@ POST_UNINSTALL = : build_triplet = @build@ host_triplet = @host@ target_triplet = @target@ +LIBOBJDIR = # dummy sources for libtool @onestep_t...@am__append_1 = libgfortran_c.c libgfortran_f.f90 @@ -953,7 +954,10 @@ gcc_version := $(shell cat $(top_srcdir) LTLDFLAGS = $(shell $(SHELL) $(top_srcdir)/../libtool-ldflags $(LDFLAGS)) toolexeclib_LTLIBRARIES = libgfortran.la libgfortran_la_LINK = $(LINK) -libgfortran_la_LDFLAGS = -version-info `grep -v '^\#' $(srcdir)/libtool-version` $(LTLDFLAGS) -lm $(extra_ldflags_libgfortran) $(version_arg) +libgfortran_la_LDFLAGS = -version-info `grep -v '^\#' $(srcdir)/libtool-version` \ + $(LTLDFLAGS) -lm $(extra_ldflags_libgfortran) \ + $(version_arg) -no-undefined + myexeclib_LTLIBRARIES = libgfortranbegin.la myexeclibdir = $(libdir)/gcc/$(target_alias)/$(gcc_version)$(MULTISUBDIR) libgfortranbegin_la_SOURCES = fmain.c -- Summary: MinGW Fortran patches for libgfortran/Makefile.{in,am} Product: gcc Version: 4.5.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: fortran AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: burnus at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40549
