[New-bugs-announce] [issue6029] FAIL: test_longdouble (ctypes.test.test_callbacks.Callbacks) [SPARC/64-bit]

[Peter Bray]

New submission from Peter Bray <pdb_ml at yahoo.com.au>:

Greetings,

  I have downloaded and compiled Python 3.1b1 on Solaris 10 Update 6
with GCC 4.1.2 on {SPARC,x86} x {32-bit,64-bit} and encountered only one
test harness failure, which was on SPARC 64-bit.

  Included below are the initial details, is there something more I can
do to assist, if so, please be specific.

Regards,
Peter

Build Procedure
---------------

Python 3.1b1

## Note PKGS_PREFIX=/pkgs/64-bit and PKGS_RELEASE=/pkgs/64-bit/release

gtar fxv <path>/Python-3.1b1.tar.bz2
cd Python-3.1b1

# The CPPFLAGS & LDFLAGS are used by setup.py in external modules builds
CPPFLAGS="-I${PKGS_PREFIX}/include" LDFLAGS="-L${PKGS_PREFIX}/lib"
./configure --prefix=${PKGS_RELEASE}/Python-3.1b1
--datarootdir=${PKGS_RELEASE}/Python-3.1b1 --with-universal-archs=64-bit 

echo "crypt cryptmodule.c" >> Modules/Setup.local  ## Solaris does not
need -lcrypt

gmake
gmake test
