Hi all,

Here is some trace I get from the kernel (2.4.18-pa19) make (after a make
oldconfig):

I do think that lacks a header to define some function.

this code is crufty old HPUX stuff... the warnings have been there
basically forever, and nobody's bothered to fix them.  Nobody's found a
problem either :-) If you want to eliminate these warnings by declaring
everything properly, feel free to send a patch, but I don't think it's
very important.

Here's the README in the math-emu directory which describes why we
leave the warnings in:

"All files except driver.c are snapshots from the HP-UX kernel.  They've
 been modified as little as possible.  Even though they don't fit the
 Linux coding style, please leave them in their funny format just in case
 someone in the future, with access to HP-UX source code, is generous
 enough to update our copies with later changes from HP-UX -- it'll
 make their 'diff' job easier if our code is relatively unmodified.

Sure, but I don't think adding

#include "math-emu.h"

to each file will make anyone's life more difficult.  Nor even

float sfod(float, float);
float ssinf(double);

Thanks for info.

In fact I test to compile this kernel with gcc-3.2 (snapshot) and severall time
it failled and I suspect wrongly that it could be the cause but it is certainly
somewhere else (don't rememnber exactly). Never the less  I will try to make
this patch.

[parisc-linux] gcc-3.2 for parisc

[James Mcclain]

hello all,

i've seen a bit of discussion lately about people using the gcc 3.2
snapshot on parisc linux.  i would like to know if anyone has provided or
will provide a guide to getting it going on parisc linux at all?

are you talking about the mainstream gcc 3.2 from the gcc cvs development
tree?  i haven't been able to compile that at all.  i tried with my old
gcc 3.0.2 on my parisc box, and i also tried to cross compile it with the
latest x86 cross compiler from the ftp.parisc-linux.org.

when i try to compile it i'm overcome with internal compiler errors, so i
guess with a newer or better compiler i could build it but of course there
is the cache-22.

thanks,
james w. mcclain

Yes.

The trick as I recall is to compile stage1 with -O2.  You should also
build cvs binutils and install it first.

i plan to build unofficial debian packages of these tools in the near
future.

[-- Attachment #1: Type: text/plain, Size: 13229 bytes --]

Here is attached a patch to avoid 'implicit' warning at compile time.
It is mainly a lk-math-emu.h file collecting math-emu functions 
prototype and also some try to unify the declaration of functions.

Please let me know your opinion.

Humm some other type of warning appear so:
