[theora] libtheora fails to compile examples on Solaris

[Roland Haeder]

Hi together,

I have compiled so far a lot libs and already some programs on my
Solaris 5.7 box (old, I know). When I try to compile libtheora the
examples are not compiling:

make[2]: Entering directory
`/export/home/quix0r/more/libtheora-1.0/examples'
if gcc -DHAVE_CONFIG_H -I. -I. -I.. -I../include

        then mv -f ".deps/png2theora-png2theora.Tpo"

bash-3.2$ 

As I can remember from other libs, their configure script checks for
that missing alphasort symbol and if it is missing, like on my machine,
it tries other sorter as well.

Maybe you can rewrite your configure script for checking the existence
of alphasort? Unfortunally I am not a C++ guru and I don't know an other
sorter.
