[PATCH] libgfortran: Fix libgfortran.so versioning on Solaris with subdirs

[Rainer Orth]

[-- Attachment #1: Type: text/plain, Size: 1036 bytes --]

The move of libgfortran objects to subdirectories completely broke the
creation of libgfortran.so on Solaris.  Since the gfortran.ver-sun rule
doesn't support that structure, no libtool objects are found, thus no
symbols exported from libgfortran.so, causing every link to fail.

This patch fixes this by allowing for the new structure.

Tested on i386-pc-solaris2.11 and sparc-sun-solaris2.11.

Ok for trunk?

Btw., I'm the first to admit the current way of performing those
filename/pathname transforms from libtool objects/archives to regular
objects/archives in the Makefiles is incredibly fragile.  It should be
handled in make_sunver.pl itself instead, but for now this needs a quick
fix.

OK to push, given it’s localised inside LIBGFOR_USE_SYMVER_SUN.

I find it weird though that .libs is harcoded there. If we look at all the lib*/Makefile.am in gcc, the only thing that ever needs to specify .libs is for Solaris versioning. It feels like it should be more generic, as you say (but that’s for longer term).

look again ;-) libgo/Makefile.am has other unrelated instances for both
setting LD_LIBRARY_PATH and related to AIX.

It seems that libtool has no provision for operations other than compile
(create .lo from sources) and link (create executable from libtool
objects/archives).  It you need something else, there's no way but to
reach below the abstraction.  I believe libtool could provide something
like this, but apparently it doesn't.
