[Bug-gsl] Building issue with the pgi and the cray compiler from version 1.12 and onwards

[Jacob Weismann Poulsen]

Hello Guys

First of all, thanks for your efforts on GSL. The other day I was asked 
to help building
GSL on our cray-XT5 system and it was straightforward for 3 (gnu, intel and
pathscale) out of 5 compilers (pgi and cray) that I tried. All builds 
were done like:

CC=cc CXX=CC ./configure --disable-shared --enable-static

Now, for the PGI and the Cray compiler, there was a problem with multiple
definitions of the many inlined functions, e.g.

gsl_rng_uniform, gsl_rng_get, gsl_rng_pos,...

address@hidden:~/gsl-1.14-cce/gsl-1.14> nm ./.libs/libgsl.a|grep 
'gsl_rng_uniform$'|wc -l
22
address@hidden:~/gsl-1.14-cce/gsl-1.14>

I noticed that the inlining stuff emerged when you went from version 1.11 to
1.12, cf. diff gsl-1.11/configure.ac ~/gsl_issues/pgi/gsl-1.12/configure.ac
below.

Moreover, I found that gsl-1.11 build fine for all 5 compilers whereas 
1.12 and 1.14
failed for PGI and CRAY (I assume that 1.13 would fail too, but I 
haven't tried it).

One can force the build of 1.12 and 1.14 by doing say

make "LINK=\$(LIBTOOL) --tag=CC \$(AM_LIBTOOLFLAGS) \$(LIBTOOLFLAGS) 
--mode=link \$(CCLD)  -Xlinker "-Wl,--allow-multiple-definition" 
\$(AM_CFLAGS) \$(CFLAGS) \$(AM_LDFLAGS) \$(LDFLAGS) -o \$@"

but some of the checks (not all) that one can do with

make "LINK=\$(LIBTOOL) --tag=CC \$(AM_LIBTOOLFLAGS) \$(LIBTOOLFLAGS) 
--mode=link \$(CCLD)  -Xlinker "-Wl,--allow-multiple-definition" 
\$(AM_CFLAGS) \$(CFLAGS) \$(AM_LDFLAGS) \$(LDFLAGS) -o \$@" check

fails. Thus, this doesn't seem to be the way to go. I tried to google 
this but
wasn't able to find a work-around. I found

http://lists.gnu.org/archive/html/bug-gsl/2009-08/msg00001.html

which seems to address the same issue. The work-around mentioned in the 
install
file and mentioned in the reply to the thread above doesn't work. I tried:

C=cc CXX=CC CFLAGS="-DGSL_C99_INLINE" CXXFLAGS="-DGSL_C99_INLINE" 
./configure --disable-shared --enable-static
make

for both compilers and the situation was the same as without the 
preprocessor flags.
I can try to dig further into this but before doing so, I would 
appreciate any comments
that you may have on this.  Thanks a lot in advance,

Cheers, Jacob
