compiling on AIX 5.3 with vacpp

[pruebauno]

I am trying to compile Python 2.5 on AIX 5.3. I used

export PATH=/usr/bin:/usr/vacpp/bin

OPT=-O2 ./configure --with-gcc="xlc_r -q64" --with-cxx="xlC_r -q64"
--disable-ipv6 AR="ar -X64"

make

The following error stops make in its track:

building '_locale' extension
../Modules/ld_so_aix xlc_r -q64 -bI:Modules/python.exp
build/temp.aix-5.3-2.5/home/pxadm/.test/Python-2.5/Modules/_localemodule.o

Stop.

Any help appreciated as to explain what that error could mean and
possible ways of fixing it.

The problem is that an additional library is needed to link the locale
module. You will first need to determine what library is needed.
Maybe libintl? To find out, you can do a man on any of those symbols,
for example, man textdomain.

That should tell you want library is required. You will then need to
modify setup.py to add the extra library for the locale module.
There's already some support for this in setup.py around line 390:

# access to ISO C locale support
data = open('pyconfig.h').read()
m = re.search(r"#s*define\s+WITH_LIBINTL\s+1\s*", data)
if m is not None:
locale_libs = ['intl']
else:
locale_libs = []
if platform == 'darwin':
locale_extra_link_args = ['-framework', 'CoreFoundation']
else:
locale_extra_link_args = []


exts.append( Extension('_locale', ['_localemodule.c'],
libraries=locale_libs,
extra_link_args=locale_extra_link_args)
)

Once you get something working, please post a patch.

Thanks for the info Neil,

sorry for taking long to answer. This is skunkwork, I am working on it
whenever I get some time.

indeed as you say. libintl.h is required so I hard coded it into
setup.py to no effect. At what point does setup.py get called? by make?

my code
# access to ISO C locale support
data = open('pyconfig.h').read()
m = re.search(r"#s*define\s+WITH_LIBINTL\s+1\s*", data)
if m is not None:
locale_libs = ['intl']
else:
locale_libs = []
if platform == 'darwin':
locale_extra_link_args = ['-framework', 'CoreFoundation']
else:
locale_extra_link_args = []

locale_libs=['intl']

exts.append( Extension('_locale', ['_localemodule.c'],
libraries=locale_libs,
extra_link_args=locale_extra_link_args) )

Yes. When you do make, python itself is built. After that, with the
built python setup.py gets called to build all the modules.

BTW, it's best to copy me on all mails as I read c.l.p only
occassionally.
