Build problem on ABM AIX + solution

Build problem on ABM AIX + solution

[eric.van.der.velde]

Trying to make gsl on an IBM AIX 4.3 (xlc) system failed in the file
test/results.c (problems concerning the va_list)

The problem is that __STDC__ is not defined on an AIX system (which should
be), and the prepocessor takes the 'wrong' decision.
To solve this problem I modified the test/results file all the occurences
of

#ifdef __STDC__

to

#if defined(__STDC__) || defined(AIX)

Then I added -DAIX to the CFLAGS and ran ./configure again (followed by a
make)

I hope this can solve you build problems on AIX in the future



Here some info on the AIX compiler:

the IBM C compiler doesn't define __STDC__ (despite the fact
that its entirely ANSI compatible - actually it does define __STDC__ if
you put it in "strict" mode, but then it treats an allocation of an "int"
to an "unsigned int" as a severe error and stops. Thus nobody uses the
strict mode, thus __STDC__ is rarely defined. In addition it generates an
error message if you define __STDC__ manually....) Therefore could you put
in a || defined (AIX) to all your #ifdef __STDC__...?

Thanks for the bug report.

Can you try this, 

go into test/results.c and change

  __STDC__ 

to 

  STDC_HEADERS

throughout (there are several occurrences).  Assuming the configure
script has defined STDC_HEADERS correctly in config.h this should
work.

Let me know and I'll make the change.

Ick. This is not necessary. We have *no* problems with GSL 0.9.2 on
AIX 4.3.2 with xlc 5.0.2.0.

This change is recommended in the autoconf manual so I plan to apply
it anyway, but I'd like to know if it fixes this problem (it should do
I think).

 - Macro: AC_HEADER_STDC
     Define `STDC_HEADERS' if the system has ANSI C header files.
     ....

     Use `STDC_HEADERS' instead of `__STDC__' to determine whether the
     system has ANSI-compliant header files (and probably C library
     functions) because many systems that have GCC do not have ANSI C
     header files.

./configure ;  make should work. If there's an error you could send
it to the list.

Have you tried
  $ CC=cc CFLAGS="-64" LDFLAGS="-64" ./configure ...

I think GCC can do 64-bit builds on IRIX as well.

I'll add this to the machine-specific installation notes.

A somewhat related question. I'm using GSL version 0.9.3
On these IRIX machines, one can build/install multiple versions of the
GSL (O32, N32, 64). The LD_LIBRARYxx_PATH family can help the
linker find the right one but...

I'm finding that the most recent install of GSL (ie. the one I install
last)
provides the "gsl-config" script which is used by gsl.m4
To remedy this, I use the ./configure --exec-prefix=/a/different/place
to configure GSL so I get multiple gsl-config scripts.

Then my application, which depends on GSL and therefore uses gsl.m4,
searches out gsl-config. To tell it which one to use, I
configure my application package with
./configure --with-gsl-exec-prefix=/a/certain/place

This all seems to work except that there seems to be bug
in gsl.m4 in extracting the major/minor/micro version numbers.

Specifically, while lines 37,38 (major) and 43,44 (minor) show:
    gsl_major_version=`$GSL_CONFIG $gsl_args --version | \
           sed 's/^\([[0-9]]*\).*/\1/'`
-- and --
    gsl_minor_version=`$GSL_CONFIG $gsl_args --version | \
           sed 's/^\([[0-9]]*\)\.\{0,1\}\([[0-9]]*\).*/\2/'`

lines 49,50 (micro) show:
    gsl_micro_version=`$GSL_CONFIG $gsl_config_args --version | \
           sed
's/^\([[0-9]]*\)\.\{0,1\}\([[0-9]]*\)\.\{0,1\}\([[0-9]]*\).*/\3/'`

The subtle difference is the argument passed to GSL_CONFIG. In the first
two cases, it gets sent "--with-gsl-exec-prefix=/a/certain/place" which
is wrong (gsl-config doesn't accept that (any?) argument). The micro
version
works, but it too may have a lurking problem. There is no variable 
called $gsl_config_args defined anywhere. I don't know what the intent
was for argument passing to $GLS_CONFIG but sending nothing works for
me!

Thanks,
Bill

Thanks for the bug report I've cleaned up the gsl.m4 file in CVS now.

I am using IRIX 6.5 on a SGI Origin.  On this machine, make uses gcc to
compile.  Would you know what  flags I would need to set in order to
make a 64-bit GSL library?

I have actually tried setting CFLAGS = -mabi=64 and LDFLAGS= -mabi=64.
However the build failed. I got the following error:

     ld32: FATAL 12: Expecting n32 objects: sasum.o is n64
     collect2: ld returned 4 exit status

I am not sure if I set the correct flags.

Thank you in advance.

Hmm.. nobody seems to know.  Maybe look on one of the IRIX newsgroups
as it is a general problem. If you find out let me know also and I
will add it to the installation notes.

Ick! Please do *not* do this. Platform-specific stuff like this is
ugly. A more proper fix should be found.

I have xlc 5.0.2.0. Without *any* options, __STDC__ == 1. What do you
consider "strict" mode? -qlanglvl=ansi?

We built gsl-0.9.2 with xlc and -qlanglvl=ansi and test/results.c
compiled fine.

Re: how do you build a 64-bit library on IRIX

[Charlie Zender]

It looks to me like you are using the correct flags (-mabi=64)
but that somewhere, somehow, you are attempting to link to a 32 bit
object file. Many IRIX systems keep the 32-bit and 64-bit versions
in different locations so make sure you are pointing to the correct
ABI libraries (with -L flag to linker)

Here are the flags I use to build 64 bit libraries on IRIX with gcc:

C++ := g++ -w
CC := gcc
GCC_ABI_FLG := -mabi=64
GCC_LDFLAGS_SZ_SPC := ${GCC_ABI_FLG} -mips4 -L/usr/local/lib/mabi=64
LDFLAGS += $(GCC_LDFLAGS_SZ_SPC)
CFLAGS += ${GCC_ABI_FLG} -O2 -Wall
C++FLAGS := ${CFLAGS}

Good luck,
Charlie
