Is GCC from Source possible?

Curtis Steward — Tue, 13 Jul 2004 16:31:32 GMT

Does anyone have a detailed HowTo or step-by-step on compiling GCC from source (binutils works)? I've tried both DSPP's: http://h21007.www2.hp.com/dspp/tech/tech_TechSoftwareDetailPage_IDX/1,1703,547,00.html

and Merijn's:
http://mirrors.develooper.com/hpux/

without success. I've attempted this with the latest known patches on both 11.00 and 11.11 on more than one machine and usually end up
with a "unknown pseudo-op" error. I'd greatly appreciate a detailed step through on any of the above.

TIA,

Hi,
A long time since I last tried...
I seem to remember having to start by compiling bison
then gcc, and after ncurses

I will have a look and see if I can find some old notes...

Good luck

Victor

I can't imagine it's this difficult to get GCC to compile on HP-UX/PA-RISC.

Anyone know of a way to get a step-by-step from the above like HP themself, complete with patch detail? Each site provides the source with a GNU linker, just can't get either to compile with the information provided.

that is most likely an assembler errror. Are you sure you were using the right combo?

Did you use the scripts I made available on my site?

My sequence from scratch:

1. build 32bit binutils from scratch with HP C-ANSI-C
2. install
3. build 32bit gcc using those binutils
4. install
5. rebuild binutils with that gcc
6. install
7. rebuild gcc with gcc and binutils
8. install
repeat 5,6,7, and 8

same for 64bit, but that is much harder and manual intervention is needed in step 1 and 3, because 64bit gcc cannot be built with cc built binutils

so most of the time it's easiest to fetch a precompiled binutils/gcc FOR THE RIGHT ARCHITECTURE and OS VERSION and replay 5 .. 8 only once

FWIW if above steps pass, I usually also rebuild gdb with it
FWIW2 I often disable ranlib and ar from binutils on HP-UX and AIX, because they tend to not play nice with HP objects

Enjoy, Have FUN! H.Merijn
