Hi Tristan,

Thanks for the patch and this endeavor.

I think after building you will run into the same issue when using
gfortran. The linking of -lm is hardcoded in gcc/fortran/gfortranspec.c
(search there for MATH_LIBRARY).

And it is hard coded in libgfortran/libgfortran.spec.in and in the
as-needed check of libgfortran/acinclude.m4 within a libquadmath check.

Talking about libquadmath, its libquadmath/configure.ac has the same issue.

To your patch:

First, I am far from being a configure expert and thus would like if
a build maintainer could have a look (or Janne, who seems to have also
more experience.)

I don't understand the purpose of the line:

+# Check for libm
+AC_CHECK_LIB([m],[sin])

Except of printing to stdout and to the logs whether -lm is available and
contains "sin", it doesn't seem to do anything. If that's the purpose, I think
it needs a better comment. If not, I would like to know its purpose.

Otherwise, the patch looks fine to me - but as written, I would like if
someone else (build maintainer, Janne, ...) could have a look.

A target may redefine MATH_LIBRARY to "" to avoid linking with -lm, and this is
correctly handled by gfortranspec.c.  After defining MATH_LIBRARY in vms.h, I was
able to cross build a hello whorl fortran program.

So that part is already correctly handled!

I have to check that.  I was able to build libquadmath without errors, but I
didn't look at config.log, so I may have missed issues.

Sure.

The purpose is to check for the presence of -libm.  If found, all tests will be linked
with -lm, which is necessary for the following tests on regular platform.  Indeed, I
should improve the documentation.

Thank you for your prompt reply,

Hi,

this is version 2 of the patch.

The initial problem is that libgfortran configure.ac used AC_CHECK_LIB([m]…) to check wether several math functions are available.  That doesn't work on VMS, because there is no such things as a libm.

It seems to me that there are no autoconf macro to check wether a function is available: AC_CHECK_FUNC[S] don't allow to specify additional include files (necessary on VMS as some math functions are renamed through macros), and AC_CHECK_DECL only checks the presence of the declaration (as pointed out by Ralf).

So I have finally learnt a little bit more about autoconf and added a new file: config/math.m4 (build machinery maintainer cc:)
libgfortran/configure.ac now uses the new GCC_CHECK_MATH_FUNC macro.

Bootstrapped without gfortran regressions on x86_64-darwin.

Ok for trunk ?

(I will submit a follow-up change in libquadmath once this change is approved).

Tristan.

Anybody else seeing something similar? The strange thing is that even
though there is an error the bootstrapping continues just fine. Though
I haven't had time to look into it deeper.

Yes, I can reproduce that.  Autoheader returns 1 as exit status even for warnings.
I am investigating (I suppose that adding a description will fix the issue).

Hi,

this patch fixes this issue.  Is it OK ?

Maybe we should include the AC_DEFINE action within GCC_CHECK_MATH_FUNC.  Will try to do that.

Sorry for not having noticed this issue before.

Tristan.

2012-03-27  Tristan Gingold  <gingold@adacore.com>

	* configure.ac: Add description to AC_DEFINE in
	GCC_CHECK_MATH_FUNC.
	* configure: Regenerate
	* config.h.in: Regenerate.

Ok.

That looks like a cleaner solution, yes, and less chance for typos to sneak in.

No problem. Thanks for fixing it quickly.

No check-gfortran regressions on x86_64-darwin, committed.

Hi,

here is the 'cleaner solution': now GCC_CHECK_MATH_FUNC automatically define the HAVE_xxx variable.

The description is now: Define to 1 if you have the `xxx' function.  As a consequence, libgfortran/config.h.in was regenerated (with differences like:
 
-/* acos is available */
+/* Define to 1 if you have the `acos' function. */
 #undef HAVE_ACOS
 
)

Tested by rebuild libgfortran for ia64-hp-openvms and visual inspection of differences.

I have CC: Paolo as he approved the first version of math.m4.

Ok for trunk ?

Tristan.

Ah, indeed.  I missed that.

So, I should use AC_LINK_IFELSE instead, shouldn't I ?

IMO, no.

What you are doing here is to replace checks, which check for presence 
of a symbol in a library (e.g. cos in libm.*) by checks for presence of 
a symbol's declaration inside of a header.

This is something entirely different (This also reflects in 
AC_CHECK_DECL by default providing HAVE_DECL_XXX defines).

Also note that it's not uncommon to have declarations inside of headers, 
which are not present inside of a library.

Hi,

I am starting to build fortran for VMS.

The first serious issue was with libgfortran/configure.  It checks for several math functions, but directly in libm using AC_CHECK_LIB.
But there is on such things as libm on VMS systems (thus requiring to define MATH_LIBRARY as "").  Therefore all these tests fail,
resulting in a failure during libgfortran build.

I think the best way to test for the math function is to use AC_CHECK_DECLS as hinted by the autoconf manual
(cf the AC_CHECK_DECLS example in http://www.gnu.org/software/autoconf/manual/autoconf.html
         AC_CHECK_DECLS([j0], [], [], [[#include <math.h>]])
         AC_CHECK_DECLS([[basename(char *)], [dirname(char *)]])

)
but I am not an autoconf expert.

I think that this change makes the AIX specific check for __clog obsolete, but I haven't removed it.

With this change I was able to cross build libgfortran for VMS (ia64 and alpha).
I have also bootstrapped gcc for x86_64-darwin, without fortran regressions.

Ok for trunk ?
