Assembler errors in compiling Blender from svn source

Coding Python Support

Hi guys,

I’ve been getting some rather strange error messages when I try to compile blender from svn source, these messages look like there is something wrong with the assembler, or the assembly code:


/tmp/cc5CkPlg.s: Assembler messages:

Would anyone know what’s going on here? :confused:

Thanks a lot.

I guess this happens during the ffmpeg code compilation. Can you post the very first error message?

It does seem like that it happened during the ffmpeg code compilation. However, the line:
/tmp/cc5CkPlg.s: Assembler messages:

was the very first error message.

There were a bunch of pointer warnings before the
errors though, and here they are:

Thanks a lot for the incredibly fast reply!

I have not encountered this myself, but from what I can gather, you may need to make sure you have the proper version of the assembler installed - you’ll have to search the net to find out what the right version is, though :confused:

^^ what’s the name of the assembler program?

I’ve been compiling blender from svn source for a few months, and this is the first time I’ve had a problem like this.

6

The assembler used is nasm.
I guess you are on Linux. Maybe your repo was updated some time ago with a new version that does not like ffmpeg’s code.

7

^^ that could certainly be the reason, i did an upgrade maybe half an hour before recompiling the latest blender from svn, and that was the first time I got the assembler error …

does anyone else who have the latest nasm that have the same problem?
