Note: hp-check can be run in three modes:
1. Compile-time check mode (-c or --compile): Use this mode before compiling the HPLIP supplied tarball (.tar.gz or .run) to determine if the proper dependencies are installed to
successfully compile HPLIP.
2. Run-time check mode (-r or --run): Use this mode to determine if a distro supplied package (.deb, .rpm, etc) or an already built HPLIP supplied tarball has the proper dependencies
installed to successfully run.
3. Both compile- and run-time check mode (-b or --both) (Default): This mode will check both of the above cases (both compile- and run-time dependencies).

[shunmugaraj (shunmugaraj83)]

Hi Liphtier,

I tried to Reproduce the issue, I could not reproduce.

Following are the versions i used

Ubuntu 10.10

HPLIP-3.11.3

Cups 1.4.4

I would like to check following things

1. Check weather you have .hplip folder created in you home directory where you are running hp-sendfax

2. Check weather it has fab.pickle file created or not

3. If 1 and 2 are ok, Add log.error("prop.user_dir =%s" %prop.user_dir) at line number 208, and let me know what "prop.user_dir" is pointing to, it should have a path to .hplip folder in your home directory.

Please try the above steps and let me know the results.

Thanks and Regards,

Shunmugaraj

[Liphtier (liphtier)]

Hi!

1. I have the .hplip folder in my home profile
2. The file fab.pickle looks corrupted, its size is 6 bytes and in text editor I see just few unreadable characters

I deleted the file and ran the hp-sendfax - the file was recreated in the same unusable state.
So the step 3 is impossible

Thank you

[Liphtier (liphtier)]

Yes, when I ran the hp-sendfax, the segfault happened as expected

[shunmugaraj (shunmugaraj83)]

Hi Liphtier,

Since address book does not have any entries added you are seeing file with small size.

Could you please add "log.error("prop.user_dir =%s" %prop.user_dir)" line before "self._fab = os.path.join(prop.user_dir, "fab.pickle")" line in "/usr/share/hplip/fax/fax.py" file and relaunch the hp-sendfax and let me know "prop.user_dir" is acutally pointing to .hplip folder in you home directory.

Thanks and Regards,

Shunmugaraj

[Liphtier (liphtier)]

Yes, it points to actual .hplip folder in my home directory when run by regular user

Actiually I deleted /root/.hplip earlier trying to solve the problem and assuming that it should be recreated. But it wasn't
