Hi all!
I'm at work - newly hired - and I'm given this mpeg2 video codec

http://www.mpeg.org/MPEG/video/mssg-...-software.html

and in particular the decoder that exists in the folder mpeg2v12.zip.
It is code c written for gcc, so I decided to download MinGW and DevC/C++. I add all the files to the project and then clicked compile.Compilation always stops though because of errors with the linker:

[Linker error] undefined reference to `__cpu_features_init'
140:8 C:\MPEGORG_CODEC\src\mpeg2dec\spatscal.c ld returned 1 exit status

I am trying to solve this problem the whole day.I tried rebuild all, clean, compile, with all possible combinations but nothing worked.
I noticed though while googling a lot of links reporting linker errors with dev-c++.

I am just started learning C and C++ and I feel very discouraged...
Anybody any idea?


compilation log is attached.

That error means it can not find the function cpu_features_init() in any of the file it compiled or in any of the libraries it is trying to link.

Check out those warnings -- they might actually be errors which are causing that link problem.

Could you tell us what include directives you used?

thanx a lot! i solved my problem - actually I don't know what was exactly.It just took me a day, of trying, and all of a sudden..

it might have been a small unintentional change to my code, who knows...
