Building a "Canadian" gdb

[Robert Trask]

The "Canadian" notation is taken from the gcc terminology wherein a compiler intended to run natively on some platform is cross built on another.

That's what I am trying to do with gdb - as a way around the pthreads problem I've reported elsewhere.

 

In this case I have a Linux server, intel arch and a cross compiler targeting mips-linux. I thought I could build a "Canadian" gdb on the Linux/intel host thus:

 

../configure --target=mips-linux --prefix=<dest dir> --with-solib-absolute-prefix=<shared lib dir> --host=mips-linux --build=i686-pc-linux-gnu

 

I get the following error message while building:

Am I doing something wrong or is this just not supported?
