Skip,

I've tried compiling both Python 2.1.1 and 2.2.x on Solaris 8 and 9
with gcc 2.9x and 3.x in my path. I consistently get the same build
error each time, so it is likely that there is some *switch* I am not
setting somewhere.  When trying to compile Python I simply run
configure/make as 'root' without modification.  Configure runs without
error, but the build dies part way through claiming several 'function
declaration isn't a prototype'.

Is there a site which covers building Python in a Solaris environment
or maybe you could post a few pointers?

Thanks, any help greatly appreciated.
