Trouble running pyinstaller generated executable on different servers
Paul Whipp
I installed pyinstaller-1.5.1 on my 10.04 Ubuntu system and used it to build two command line utilities with a script as follows:
#!/bin/bash python pyinstaller-1.5.1/Makespec.py -Fso /tmp orb_development_proxy.py python pyinstaller-1.5.1/Build.py /tmp/orb_development_proxy.spec cp /tmp/dist/orb_development_proxy . python pyinstaller-1.5.1/Makespec.py -Fso /tmp orb_live_proxy.py python pyinstaller-1.5.1/Build.py /tmp/orb_live_proxy.spec cp /tmp/dist/orb_live_proxy .
The resulting executables work perfectly on the 10.04 system. Great stuff!
Then I copy the executable to a couple of my servers for testing.
On Centos 5.5 running a fairly typical web hosting setup I get -
/home/evanidus-sandbox/public_html # ls -l | grep orb_proxy -rwxrwxrwx 1 evanidus-sandbox evanidus-sandbox 3425777 Feb 22 19:35 orb_proxy -rwxrwxrwx 1 evanidus-sandbox evanidus-sandbox 3706 Jan 17 16:11 orb_proxy.py /home/evanidus-sandbox/public_html # orb_proxy.py ping merchant merchant 1 /home/evanidus-sandbox/public_html # orb_proxy ping merchant merchant Error loading Python lib '/tmp/_MEIMkjue6/libpython2.6.so.1.0': /lib/libc.so.6: version `GLIBC_2.7' not found (required by /tmp/_MEIMkjue6/libcrypto.so.0.9.8)
On Ubuntu 11.10 (EC2) I get -
~/python/orb/merchant $ ls -l | grep orb_dev -rwxr-xr-x 1 ubuntu ubuntu 3425772 2012-02-23 00:50 orb_development_proxy -rwxrwxr-x 1 ubuntu ubuntu 335 2012-02-23 00:50 orb_development_proxy.py ~/python/orb/merchant $ orb_development_proxy.py ping merchant merchant 1 ~/python/orb/merchant $ orb_development_proxy ping merchant merchant -bash: ./orb_development_proxy: No such file or directory
So in both cases the python script works (these servers have python 2.6.5 and the special modules all set up - this wont be the case on other targets) but the executable produced by pyinstaller fails.
Looking at ldd -
/home/evanidus-sandbox/public_html # ldd orb_proxy linux-gate.so.1 => (0xffffe000) libz.so.1 => /usr/lib/libz.so.1 (0xf7f0b000) libdl.so.2 => /lib/libdl.so.2 (0xf7f06000) libc.so.6 => /lib/libc.so.6 (0xf7dad000) /lib/ld-linux.so.2 (0xf7f28000)
All these dependent files exist on the Centos 5 server.
On the 11.10 server, ldd tells me the orb_development_proxy "is not a dynamic executable" - the executable is identical on all 3 systems (checked with md5sum) - its renamed on the web server for implementation reasons.
My ultimate intention is to distribute the executable for use on a range of web servers running Linux.
I can't see anything untoward in the warnings.
Can someone point me in the right direction to work out how I can get the generated executable to run on these test servers?

PyInstaller exclude glibc from it's distribution as these are available on all machines.

Hmm, this is a different program?!/home/evanidus-sandbox/public_html # ldd orb_proxy

You could look at our faq: http://www.pyinstaller.org/wiki/FAQ
You need to build your app on the oldest distribution you want to
support (with oldest libc - libc is backward compatible but not
forward). I your case I think it means to build your app on centos 5.
If you depend on newer python version than the one on centos 5 then the
challenge is to build python yourself on centos 5.
Or another option is to look at http://pypi.python.org/pypi/myppy. With
python from myppy you should be able to create executables on your
ubuntu 10 which could work even on centos5.

Thanks very much for the help and feedback.
I've learned a lot trying to get this working. I tried building on an older OS (Centos 5.4) but I could not get it working right (probably because Python 2.6 which is needed for the app).
After building the bootloader as suggested and copying the relevant files (the build was on a 32 bit version of Centos 5.4 with GCLIB at 2.5 as per the target 64bit Centos server - I built using the new build files on the 32 bit development system), I still got the same issue on the Centos system. Building the bootloaders as per the manual (and faq) did not make any difference to the reported error.
Reading around I discovered that the problem on the ubuntu 11.10 system was a result of the ia32-libs not being installed by default. Installing that fixed the issue there - phew - one down.
As building the bootloaders did not work, I tried myppy. However this project seems to be languishing and it failed to initialise on 10.04 Ubuntu -

So… I tried to run everything by using python 2.6 alongside 2.4.3 on the Centos system. It built an executable but -
~/python/orb/merchant $ ./orb_development_proxy ping merchant merchant Traceback (most recent call last): File "<string>", line 24, in <module> File "/home/paul/python/orb/merchant/orb_proxy.py", line 57, in do_command getattr(self, command)(*command_args) File "/home/paul/python/orb/merchant/orb_proxy.py", line 120, in ping if self.get_proxy(username, password).safePing(): File "/home/paul/python/orb/merchant/orb_proxy.py", line 79, in get_proxy 8667) File "/home/paul/python/orb/client/proxy.py", line 17, in __init__ ServerProxy.__init__(self, uri, allow_none = True, use_datetime = True) File "/home/paul/python/orb/myxmlrpclib.py", line 1469, in __init__ import urllib File "/home/paul/python/orb/merchant/pyinstaller-1.5.1/iu.py", line 455, in importHook raise ImportError, "No module named %s" % fqname ImportError: No module named urllib ~/python/orb/merchant $ python26 Python 2.6.5 (r265:79063, Feb 28 2011, 21:55:45) [GCC 4.1.2 20080704 (Red Hat 4.1.2-50)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import urllib >>>
Not sure why the module would appear to be missing when python 2.6 can see it (python 2.4 can too for that matter). The python script runs fine (in python 2.6).
So I'm still stuck. I suspect that trying cxfreeze et al will reveal the same problem. I need to find a solution so I will keep looking.
Any further suggestions or pointing out any errors I'm making would be appreciated. I am surprised that 'building the bootloaders' did not make a difference given that its mentioned as a fix in the FAQ.
Cheers,
Paul

Cxfreeze or similar would definitely reveal the same problem.

You could try
- experiment with variable PYTHONHOME
- development version of pyinstaller
- development version of myppy
