I can build python 2.4.2 from source on the embedded linux box when I
nfs mount and boot a full debian distribution.
The embedded box also has stripped down linux distribution in onboard
flash.
My goal is to run python from the stripped down linux in onboard flash.
I can successfully install python to the onboard flash when booted to
the nfs version by using
make install with $DESTDIR set to the onboard flash mounted directory
I then reboot to the onboard flash and can run python from there.
This works if I build python without threading support because the
onboard flash does not include the
libpthread.so library
I need threading support for sockets etc.
I believe that if I can build python with pthread linked statically
then I should be able to run python when booted from the onboard
flash without problem.
Problem is I am clueless about how to do this. The setup and setup.py
files only deal with building modules static
or shared where as threading is build into the python interpreter it
seems not as a module.
I read the readme in the source distribution but can't find any
configure options that will let me build
python with static linking of the pthread library. I have searched
google and find vague references to doing something
like that. I don't understand the makefile well enough to know how to
do it there.
So does anyone understand how include threading support statically?
What I have to modify to do it?
When I tried to run python with shared threading support while booted
from the onboard flash it got the following error
../python: error while loading shared libraries: libpthread.so.0:
cannot open shared object
file: No such file or directory
I naively copied the pthread library from the nfs version to the
onboard flash version and rebooted and
ran python. This time I got the following error
/usr/local/bin/python: relocation error: /lib/libpthread.so.0: symbol
__libc_sigaction, ve
rsion GLIBC_2.2 not defined in file libc.so.6 with link time reference
so apparently I can't just copy shared libraries around.
An alternative solution would be to correctly copy the shared library?
Any help comments would be appreciated
