Requires libncurses5 instead of 6?

glubsy commented 6 years ago

Installed after doing a small modification to the setup.py by changing "python" to "python2" and changing httplib to http.client as httplib in build_firebird.py (since httplib is deprecated now). Then:

python setup.py bdist_wheel sudo pip install dist/fdb_embedded*.whl

and it seems to have installed correctly.

Now calling fdb_embedded in my script yields the following error:

Traceback (most recent call last):
  File "./fdb_query.py", line 10, in <module>
  File "/usr/lib/python3.6/site-packages/fdb_embedded/fbcore.py", line 656, in connect

Do I need to find libncurses5? Am I missing something obvious? Running Arch Linux, my libncurses shared libs are all version 6.

Edit: running an strace, it's clearly looking for libncurses5... maybe it should be bundled with it?

openat(AT_FDCWD, "/usr/lib/python3.6/site-packages/fdb_embedded/lib/libncurses.so.5", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)

Current workarounds?

OSError: libncurses.so.5: cannot open shared object file: No such file or directory

doing a symbolic link from my current Hopper installation: sudo ln -s /opt/hopper-v4/lib/libncurses.so.5 /usr/lib/python3.6/site-packages/fdb_embedded/lib

OSError: libicuuc.so.30: cannot open shared object file: No such file or directory

doing a symbolic link: sudo ln -s /usr/lib/python3.6/site-packages/fdb_embedded/lib/libicuuc.so{,.30}

I sound like a robot. bleep bloop. Or like a dumb user. derp derp.

Hi @glubsy, I haven't looked at this for a few years so I'm not too sure.... I never actually ended up using this in a project.

I suspect you may do well by updating the version of the library that's bundled; see settings and urls in https://github.com/andrewleech/fdb_embedded/blob/embedded/build_firebird.py

Thanks, I guess I should have looked closer indeed. For now, everything seems to work for me. But if I ever get around to successfully updating the install script, I'll make a pull request.

by the way, thanks for sharing this fork, it's quite useful to me (I think... just messing around)

Cheers~
