I'm trying to install gcc and g++ on a MIPS M/120 and experience difficulties. Can anyone give me an idea of what I am doing wrong. I followed the directions in the installation file and have got to the point where I am trying to compile stage1 and get the following error for just about every .o file R_GPREL relocation entry with no global pointer reference. On thing that I wasn't able to do was to run the program for converting the library to/from COFF format. I did try but was again unable to get the robotussin.c file to compile - that one appears to require a header file in which the mips version ifdef's out all the declarations that are needed.

First, I believe that you are seeing this message displayed by "ld" as it tries to link everything together, right? Well, ld is trying to tell you that he's seen plenty of references to GP relative data, but he's never seen an explicit reference to the magic "_gp" symbol. He therefore believes that you haven't provided any code which initializes the GP register and he's being anal about letting you proceed. I wrote software that loads and executes MIPS COFF files and initializes the GP register BEFORE jumping into the loaded code. Since the loaded code never initialized the GP register "ld" gave me all kinds of trouble. I then arranged for the loaded code to make a completely gratuitous reference to "_gp" so ld would be quiet and let me get on with life. It was a violation of "illegitimi non carborundum", but what can you do... Disassemble your local crt.o file for an example, if you can't find a better reference. Good luck. ---------------------------------------------------------------------------- Michael O'Donnell (508)392-2915 home(508)251-7576 ___________ / ________/__ ...!{harvard,uunet,petsd}!masscomp!mod /__/_______/ / mod@westford.ccur.com Concurrent /__________/ Computer Corporation 1 Technology Way Westford, MA 01886 DISCLAIMER: My opinions only coincidentally resemble those of my employer. ----------------------------------------------------------------------------
