Description Yan Li 2009-12-02 09:29:24 UTC 
I'm one of the Debian EDS maintainer. While checking the libraries generated, I found libraries with undefined symbols. This indirect linking per se is not a big problem (yet) but causes package checking warnings.

For example:
dpkg-shlibdeps: warning: symbol __dn_expand used by debian/libexchange-storage1.2-3/usr/lib/libexchange-storage-1.2.so.3.0.0 found in none of the libraries.
dpkg-shlibdeps: warning: symbol e_passwords_ask_password used by debian/libexchange-storage1.2-3/usr/lib/libexchange-storage-1.2.so.3.0.0 found in none of the libraries.
[...]

Above warnings said that libexchange-storage used functions from libedataserverui but was not linked against it. This may cause problems to programs using libexchange-storage other than Evolution (e.g. Anjal or sth else).

Do you agree that this can be fixed by adding missing libraries to respective lib_*_LDADD? Or do you have any other concerns?

Thank you.

Those libraries can be filtered by building with "-Wl,--no-allow-shlib-undefined".
Comment 2 Matthew Barnes 2010-03-31 16:24:11 UTC 
Is this still an issue in Evolution-Data-Server-2.30?
Comment 3 Tobias Mueller 2010-06-23 10:19:22 UTC 
Yan Li, Ping.
Comment 4 Yan Li 2010-06-30 06:09:19 UTC 
No, the problem is still in e-d-s 2.31. Without adding every libraries used to respective lib_*_LDADD, the problem won't go away automatically I think.
Comment 5 Matthew Barnes 2010-06-30 09:27:59 UTC 
Can you post the exact warnings you're seeing (all of them)?

The examples you gave don't apply anymore and E-D-S builds fine for me on Debian, which is where I turn to reproduce most of the linker errors that get reported.
