[vlc] Re: Cross Compile VLC for mips32

[Keir Vaughan-Taylor]

Why not compile everything on the MIPS machine. Cross compiling 
introduces a whole realm of possible problems. If you compile everything 
on the MIPs you can be sure none of the libraries have accidentally been 
compiled for another machine and anything missing would be revealed when 
you do the make. One reason for the segmentation might be that  library 
code from the non MIPs machine has found its way onto the MIPS machine.
