[Mjpeg-users] Re: compiling MJPEG-Toolsd with Cygwin

[Víctor P. <wz...@ho...>]

Hi,

I was able to compile mpeg2enc under Cygwin, but with the MMX optimizations 
off.

In configure you need to --disable-simd-accel, as told here:

https://sourceforge.net/mailarchive/message.php?msg_id=7703576
https://sourceforge.net/mailarchive/message.php?msg_id=7682007

Also, you will have to edit a file and do a few (four) castings to the 
proper C type (uint_32t*, if I remember well), that is obvious from the 
compile error messages.

The reason of turning off the MMX, is because the object files generated by 
nasm under Cygwin are not able to carry symbol information, and the link 
stage fails.

By reading the "ld" man page it seems that "ld" is able to link COFF and ELF 
object together, so *maybe* it could be possible to tell nasm to target ELF, 
and then tell "ld" to glue together the objects.

Unfortunately, "ld" is called via "libtool", and it exceeds my knowledge to 
find out how to do that.

Any "libtool" expert around volunteers?

Regards,
Víctor
