Compiling kernel/sched.c gives the following error: sched.c:579: section attributes are not supported for this target I am running HP-UX 10.20, so I cannot use the depots from ftp://puffin.external.hp.com/pub/parisc/binaries/depot/.

Although it does support section attributes, there is a bug in the code emitted that cannot be assembled with gas 2.9.1. I sucessfully worked around it by changing the condition from a fatal error to a warning in gas. Here is the text of the bug I submitted to gcc: e of __attribute__((__section__())) to force code into a specific section generates code which causes the assembler to fail. Here is an example: /* test.c */ int __attribute__ ((__section__ (".text.init"))) a(x) int x; { return(x+1); } int b(x) int x;{ return(x+2); } int __attribute__ ((__section__ (".text.init"))) c(x) int x;{ return(x+1); } main(){ printf("a(0)=%d\n",a(0)); printf("b(0)=%d\n",b(0)); printf("c(0)=%d\n",c(0)); } Here is the output of gcc: # gcc test.c /var/tmp/cca10410.s: Assembler messages: /var/tmp/cca10410.s:59: Warning: Parameters of an existing subspace can't be modified /var/tmp/cca10410.s:59: Error: Rest of line ignored.

I'm pretty sure you need the hacked egcs and binutils. You can check them
out of cvs from the same place as the kernel (I use them for cross-compiling
though).

You can check them > out of cvs from the same place as the kernel (I use them for cross-compiling > though). I suppose I should mention that the only reason I chose to compile gcc 2.8.1 and binutils 2.9.1 was that I was almost positive that gcc 2.8.1 would build with the bundled K&R compiler. (I couldn't find a copy of the ANSI C compiler for 11 over the weekend.) I figured that the vanilla gcc and binutils would give me enough of a development environment that I could build anything else. I have binaries of egcs 1.1.2 built, but I'm going to try to run the test suite before I put them out on puffin.external.hp.com. After that, I'll go for the CVS versions. When it looks like everything is built for 11, I'll probably go back and build 10.20 binaries of anything you can't already find on hpux.cs.utah.edu or hpux.cae.wisc.edu. BTW, I've tested the bash binary... It seems to work fine.
