[vlc-devel] I managed to cross-compile vlc for zaurus.

[Juan Antonio Martinez Navarro]

Hi everyone,

I've eventually got a vlc for the Zaurus SL-C3100.

These are the problems I got during the process:

In the compilation of libavcodec I had too many problems with huffyuv
codec so I decided to compile libavcodec without it.

After execute "ipkg/rules.zaurus config" to run configure with the rules
for Zaurus. I had to change two lines in vlc-config file.

Lines 150 and 155: ldflags ... -ljpeg
I had to put the path to libjpeg.a instead of -ljpeg.
"-L/home/dsl/Sources/jpeg6b/libjpeg.a

Afterwords. When I type ipkg/rules.zaurus or make.


I got several errors related with undefined symbols. That is because
several ".a" files formed with arm-linug-ar but they needs to be formed
with some files more. I made the attached script to change this. 

I hope this could help other people,

Thanks everybody.
