Segmentation fault when building python27

[thomas@…]

When I run "sudo port install python27" on my 10.6.7 iMac here's what I get:

:info:build /bin/sh: line 1: 60319 Segmentation fault      DYLD_FRAMEWORK_PATH=/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_lang_python27/work/Python-2.7.1: CC='/usr/bin/gcc-4.2' LDSHARED='/usr/bin/gcc-4.2 -L/opt/local/lib -arch x86_64 -bundle -undefined dynamic_lookup -L/opt/local/lib -arch x86_64' OPT='-DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes' ./python.exe -E ./setup.py -q --no-user-cfg build

Attaching the python.exe crash log and main.log

python.exe crash log

python27 build log

Since the crash is in ncurses, I should probably mention that I have the ncurses @5.9 port installed.

You don't need to CC yourself.

If you launch the command mentioned in main.log in gdb the backtrace is slightly more detailed:

#0  0x000000010165db5f in _nc_trim_sgr0 ()
#1  0x0000000101659094 in tgetent ()

I've tried to reinstall the ncurses and readline ports, to no avail.

I too hit this problem and was able to workaround it by using this variant:

sudo port install python27 +universal

As there are a bunch of dependencies which need to be updated to +universal, this took a while however it worked for me! ;-)

My machine is a Mac Book Pro running OSX 10.6.7

Hope that helps!

Mark's instructions solved my problem. Feel free to close! Thanks,

Assuming this is the same as #29771.
