compile error solaris 10 x86 32bit

[chassing]

Hi,

i try to install greenlet 0.4.0 on solaris 5.10 x86 with a 32bit python 2.6 (from opencsw.org) and i get the following compile error :(

$ CC=/opt/sunstudio_12/bin/cc /opt/csw/bin/python2.6 setup.py build

$ uname -a

notes:

• /opt/csw/bin/python2.6 is opencsw installed python2.6
• /opt/sunstudio_12/bin/cc is sunstudio compiler

any idea?

thanks,
chris

Hi, can you please try adding this:

#elif defined(__SUNPRO_C) && defined(__i386__) && defined(sun)
#include "platform/switch_x86_unix.h" /* SunStudio on x86 */

directly below this:

#elif defined(__SUNPRO_C) && defined(__amd64__) && defined(sun)
#include "platform/switch_amd64_unix.h" /* SunStudio on amd64 */

in slp_platformselect.h and see if this helps?

Hi,

i added:

#elif defined(__SUNPRO_C) && defined(sun)
#include "platform/switch_x86_unix.h" /* SunStudio on x86 */

and it compiles, but in combination with gevent it throws a segmentation fault :(

./python

yes

[snaury]

Unfortunately that is not very helpful. Did you try to run the test suite (python setup.py test)? Does it succeed or fail with a segmentation fault as well?

[snaury]

Also, if it does crash on the test suite, could you please compile greenlet with -keeptmp (I hope it does what I think it does) and send me your resulting greenlet.s file?

[chassing]

i compiled it with debug, there isnt a keeptmp option.

without TEST_CPP it segfaults too:

on solaris 10 sparc with disabled TEST_CPP all tests are ok.
the greenlet.so is in your mail inbox.

thx,
chris

@chassing unfortunately that's not what I really wanted. Could you please try building with CFLAGS=-keeptmp python setup.py build_ext and see if you end up with greenlet.s (an assembler listing) somewhere in the build directory. Also, try building with CFLAGS=-xO1 to reduce optimizations (it would be better to remove -xO3 somehow, but I don't know how and SubStudio doesn't seem to have a switch to disable optimizations after they are enabled), see http://docs.oracle.com/cd/E19205-01/820-4180/man1/cc.1.html for more optimization related options.

[chassing]

ups :) i compiled now with: /opt/sunstudio_12u1/bin/cc -keeptmp -S -I/opt/csw/include/python2.6 greenlet.c
the output greenlet.s is in your inbox :)

[snaury]

@chassing do you still experience segfaults? Could you please try compiling latest version from this repository?

Closing since it's believed fixed and there's been no response from the OP in 6 years.
