Juergen, Thank you for the feedback. I have figured out what the issue is. The default options to build openssl for the *build-host* need to be set so that at least no-ssl2 is defined, and possibly shared. I think the latter is needed because python may be looking for the dynamic lib. The default openssl build only produces the static libs. Background: In a sandbox rootfs under Linux 12.04LTS I installed openssl and found that both _hashlib and _ssl were not included in the libcrypt.a or ssl.a modules. After I ran through ./configure's options, I added shared and no-ssl2 to the ./configure command line, (as well as specifying my sandbox env using --prefix). Disabling ssl2 resolves the issue/bug with ssl2 (SSLv2_method), which can be addressed later. Having hashlib and ssl available will keep the from hashlib import md5 from failing when flup.py is installed (see original posting). Right now I'm trying to work through the ptxdist guru doc to understand how to properly modify the host-openssl.in,.make so that I can define the options to build the host-openssl correctly. More specifically, I can't find documentation as to how to enable PTXCONF_HOST_OPENSSL in menuconfig (other than manually editing the ptxconfig file) and where does HOST_OPENSSL_PKG get defined? (Running grep through ptxdist/rules only shows the host-openssl.make file). Any help would be much appreciated. Regards, jd -- ptxdist mailing list ptxdist@pengutronix.de

[ptxdist] ptxdist-2012.03.00 python2.6, hashlib.py, flup.py install fails ImportError: No module named _sha256
Hello ptxdist devel group:
I'm new to this group and somewhat new to ptxdist, so I hope this is the
right list to post this issue.
I have successfully built a target image that includes python2.6 and
lighttpd which is part of ptxdist-2012.03.00. The intent was to use flup.py
to provide fastcgi, wsgi capability. (This works in my dev env, under Ubuntu
12.04 LTS, python2.7.x).
The issue below shows up when I enable the extra python module flup in
ptxdist menuconfig, under python extra modules.
My diagnostics may not be 100% correct here, but it appears to me that the
openssl is not available when being built for the target. (Note the
references to sysroot-host/lib/python2.6 to where hashlib.py is located).
If the openssl was installed, there would be a ~/ssl directory either under
/usr/lib/ssl (default per openssl.make) or some other specified file system
(e.g., /usr/local/lib/ssl) There is no ~/ssl directory on the target at
this time.
1) How does one ensure ptxdist builds and installs openssl and then ensure
that python will use the openssl module?
2) For reference, I found the patch for flup.in, python.in here:
https://bitbucket.org/bwalle/ptxdist/commits/6e48293f380f6c115bd433f8519e7f9
6e8f0f66f
I applied this patch by copying the respective .in, .make files to my
platform ~/rules directory.
This still did not solve the problem. I'm hoping someone from this group may
be able to help get around this hashlib.py issue.
Also, would it be advisable to update to ptxdist-2012.07.00 which includes
the fix for flup? Would also like to update to python2.7 as well, but not
sure the build tool supports this yet.
I also tested the target python install by importing hashlib and testing
md5(), new(md5) both work. So not sure why this build below does not wor.
Any help or guidance would be much appreciated.
The log is below.
Regards,
JD
