python27 crashes with segmentation fault

mmwaveguy commented 8 years ago

Well I solved segmentation error by linking /lib/libc.so.6 to /opt/lib/libc.so.1 but now python complains about unresolved symbols.

do I also need a compliant version of libgcc?

Optware-ng doesn't use /lib/libc.so.6 or anything outside /opt:

[root@unknown /opt]$ ldd /opt/bin/python2.7
        libgcc_s.so.1 => /opt/lib/libgcc_s.so.1 (0x4012e000)

        libcrypt.so.1 => /opt/lib/libcrypt.so.1 (0x400d4000)
        libdb-5.3.so => /opt/lib/libdb-5.3.so (0x4015c000)
        libncurses.so.5 => /opt/lib/libncurses.so.5 (0x402e4000)

        libm.so.1 => /opt/lib/libm.so.1 (0x405b6000)
        libc.so.1 => /opt/lib/libc.so.1 (0x405d7000)

Do you happen to have LD_PRELOAD env variable set? I don't see other ways to have python2.7 load anything outside /opt.

armv5 python27 works OK on my armv7 test machine, btw:

[GCC 5.2.0] on linux2
Type "help", "copyright", "credits" or "license" for more information.

Problem Solved!

I completely uninstalled all packages and re-installed python. This worked. Must have been some conflicting libraries or something from the old package installs.

mmwaveguy commented 8 years ago

Well after all that the dreaded segmentation fault returns! Running SABnzbd fails with a segmentation fault.

mmwaveguy commented 8 years ago

Completely uninstalling all packages and deleting all files in /opt then reinstalling ipkg allowed me to run SABnzbd. However SickRage now fails with a segmentation fault.

@mmwaveguy I believe that, just like with #44, this issue is caused by kernel that is older than the headers from buildroot-armv5eabi-ng toolchain. Please try buildroot-armv5eabi-ng-legacy feed that was recently added, if you're still interested in this.

alllexx88 commented 8 years ago

Closing, since I assume this should work now with the buildroot-armv5eabi-ng-legacy feed
