Hi,
I've just tested your files with my setup (Gentoo Linux, using SynCE
to communicate with my WM5 PDA) and I've done this by creating 2
small test application's which links to respectively avcodec-51.dll
and avutil-49.dll.
These small test application's look like this :
#include <stdio.h>
#include "avcodec.h"
int main()
{
printf("hello from main\n");
avcodec_init();
return 0;
}
--
#include <stdio.h>
#include "common.h"
int main()
{
void *data;
printf("hello from main\n");
data = av_malloc(1);
printf("data = %#x\n", data);
av_free(data);
return 0;
}
--
To generate cegcc-compatible import libraries I first altered the
.def's by prepending a rule to the file like 'LIBRARY "avcodec-51.dll"'
and after that I used this command :
arm-wince-cegcc-dlltool -d avcodec-51.def -l avcodec-51.a
arm-wince-cegcc-dlltool -d avutil-49.def -l avutil-49.a
(sidenote: the arm-wince-cegcc-dlltool isn't installed by default..
I've hacked around in binutils so that this program gets generated)
Anyway, I can compile these 2 test applications with cegcc, but only
one of these two work successfully on my PDA..only the application
which uses avutil-49.dll works. The other applicaties gives the
'not a valid PocketPC application' error.
After investigating the failed testapplication with Dependency Walker
I found out that avcodec-51.dll has an reference to avutil-49.dll.
This isn't a problem normally, but there is something fishy going on..
avcodec-51.dll tries to pull in some functions from cegcc.dll
while these functions are part of avutil-49.dll.
I don't know if the avcodec-51.dll hasn't been compiled 'the right way'
or if this is a bug in cegcc, but Pedro and Danny could probably
help you further with that.
You might want to test if you can use the avutil-49.dll from Visual C++.
It should work (as long as you stay away from avcodec-51.dll).
Good luck!
Erik
