Bug 40411 – x11-misc/ttmkfdir fails to compile with 3.2.3-r4

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Matteo Sasso 2004-02-04 14:10:40 UTC]

Similar to #40338, this problem is affecting an x86. I recently "cleaned up" my Gentoo and I hope I didn't broke anything; in particular I unmerged gcc-2, so that could possibly be a cause... but maybe not! Anyway I get the following:

g++ -Wall -pedantic -I/usr/include/freetype2 -march=athlon-xp -mmmx -msse -m3dnow -O2 -fomit-frame-pointer -pipe -Wall -funroll-loops -fprefetch-loop-arrays -finline-limit=1200 -falign-functions=32 -c ttmkfdir.cpp  -fPIC -DPIC -o ttmkfdir.o

   exceptions

   declaration `int getchar() throw ()'

and other similar errors with getc_unlocked, getchar_unlocked and so on.
I tried to merge the -r4 of gcc which fixes a similar problem for the Sparc but I got no luck.
I'm working around by removing -O* from CFLAGS. Just a "cosmetical" bug, but nice to get fixed anyway.

I can confirm that this is the case.

After a fresh Gentoo install on my x86 and emerge system this did not work.

Hi, try again without an -O options.
This fixed the issue when I ran across it.

[Comment 3 Jakob Sigurdsson 2004-02-06 12:43:28 UTC]

!!! FIX FOR THIS BUG:

From #gentoo-bugs :

<tseng> you need to filter out -O
<tseng> CFLAGS="-pipe -march=whatever" emerge ttmkfdir

I ran this (with -march=i686 in my case) and ttmkfdir was succesfully emerged.

Thanks to tseng!

Fixed in 3.0.9 and 3.0.9-r1 in cvs.
