Peter,
it looks strange to me that at opal compilation time you have speexdsp
on your system and at ekiga compile time you dont. Actually the behaviour
seems normal to me:
- We build a OPAL shared library that requires speexdsp.
- When we link this library, it is checked that speexdsp symbols are working;
however the speexdsp symbols will NOT be included in the OPAL shared lib
- OPAL adds speexdsp to its PKG-requires section to tell apps linking to it
that
it accesses symbols from speexdsp
- when ekiga links to opal, it also has to link to speexdsp in order to resolve
all symbols
( you would get unresolved symbols errors if not)
- ekiga gets this information from pkg-config
