[Bug other/31400] New: enable static linking of support libraries through -static-libXY

[dfranke at gcc dot gnu dot org]

To deploy testing versions of applications built with (yet unreleased) versions
of gcc may be difficult due to linked in libraries as libgfortran and libgomp.

Similar to -static-libgcc, options like -static-libgfortran or -static-libgomp
would help to avoid problems. Especially for libgomp, one can not simply use
LDFLAGS=-static as libgomp pulls in libpthread and static linking is not
supported with libpthread (see PR30471, PR30613).

In general this is wrong.  There are reasons why you don't want static linking.
 code size/memory usage is one of them.

------- Comment #3 from dfranke at gcc dot gnu dot org  2007-03-30 16:30 -------
Andrew, I agree that static linking should not be overused. But there are valid
cases where one may want to do it anyway. Deploying a testing application may
be one of them. Asking the user to compile gcc from scratch just to get the
latest libraries is usually not an option. Delivering a bunch of libraries
together with the binary may mess up the customers system, especially if it is
a test-and-discard like approach.

Given the two PRs I cited plus the thread H. J. pointed out, there are people
looking for options like the ones requested here.

I certainly agree that we should have an option to ask the driver to link
libgfortran statically.

FX, thanks for your patch :)

As libgfortran is one of many, at least -static-libgomp would be nice to have
as well (others?). Reopening, so the request is not lost.

Any chance to ever get -static-libgomp? Otherwise this PR can probably be

The http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=126068

On Darwin - I made it so that if -static-* is given for {stdc++,cc, fortran}
the specs cause a substitution for static libgomp.  Would that work for you?

Sorry ;) - specs processing.

It's possible to detect that "-static-libgfortran" has been given on the
command line and cause that to substitute libgomp.a instead of libgomp.so.

I arranged that this would happen on darwin if any of libgcc, libstdc++ or
libgfortran were made static  (for reasons of unwind symbol consistency, rather
than to satisfy a requirement for static-libgomp).

I think it's more difficult to approach libgomp directly - since it doesn't
"belong" to any specific language - therefore whatever changes you effect to it
need to be coordinated between all FEs.

Having said that, there was a comment made that libgomp.spec might be "going
away".

Does that help?

Much. Thanks. :)

Don't know if this is still a problem, but #0 has:

Question being, is there a difference between darwin and, say, our average
linux box, that allows static linking with the one, but not with the other? In
PR30471, comment #7, Jakub once posted a semi work around to this question.

yes, there is a significant difference - threads are part of libSystem on
darwin (which is always linked dynamically).  So I guess that this is not a
solution.
