Bug 30052 – dev-php/mod_php-4.3.2-r4 fails to compile

• Status: RESOLVED INVALID
• Product: Gentoo Linux

[Description FieldySnuts 2003-10-01 04:26:09 UTC]

Using distcc, trying to emerge mod_php-4.3.2-r4 fails. In fact it specifically asks me to file a bug report here.

/var/tmp/portage/mod_php-4.3.2-r4/work/php-4.3.2/ext/bcmath/libbcmath/src/div.c: In function `bc_divide':

(it is a slow enough machine I try to do as much compiling as possible on the other host)

Thinking it might be distcc related (though I have *NEVER* seen a problem
related to distcc), i disabled usage of distcc.

I still get the error. It is exactly the same, minus the distcc line.

[Comment 2 Robin Johnson 2003-10-01 13:25:18 UTC]

Could you please try to reduce your CFLAGS to:
CFLAGS="-O3 -march=i586 -fprefetch-loop-arrays -pipe"
and try to recompile PHP.
If the same error still shows up,
recompile gcc and glibc with those cflags
and then try php again.

[Comment 3 FieldySnuts 2003-10-01 18:46:46 UTC]

Using those CFLAGS and trying mod_php again did the trick. I did not have
to touch gcc or glibc.

So, what flag(s) shouldn't I have had?

[Comment 4 Robin Johnson 2003-10-01 18:51:57 UTC]

could you emerge genflags
and run:
"info2host ; info2flags"
and paste all 5 lines out output here.

And try:
CFLAGS="-O3 -march=k6 -fprefetch-loop-arrays -pipe"

I'd like to see the contents of your /proc/cpuinfo as well.
