MIPS port in CVS HEAD?

[david daney]

First of all, appologies for the screwed up mail formatting, I am using a crappy web mail client....
 
I thought I would reply, although I don't have access to my development systems right now so this is from memory.  If you are still having problems, I can reply with more definitive information on Monday.
 
I think this error is due to an incorrect includes path.  What options did you configure with?  There are top level configure options to set the location of the system include directory.  You have to set this and also have it populated with something close to the proper files.
 
I think there may be a chicken and egg type problem with building the compiler and libc, so you might have to get creative in creating an initial set of system include files.
 
Also you need to take a look at this thread:
 
http://gcc.gnu.org/ml/gcc-patches/2003-10/msg00607.html
 
There has been no resolution to the problems outlined there.  Perhaps the MIPS maintainers will OK the patch so that we can again build from unmodified cvs sources soon.
 
David Daney.
