Bug 45637 – mjpegtools-1.6.1.90-r2 doesn't compile with -O3

• Status: RESOLVED INVALID
• Product: Gentoo Linux

[Description Ludootje 2004-03-24 12:37:57 UTC]

I wanted to emerge k3b, and mjpegtools is one of its requirements.
When emerge tried to 'make' mjpegtools-1.6.1.90-r2, this error occured:

!!! compile problem

Because of the line "gcc: unrecognized option `-03'", I tried to remove the '-O3' of my CFLAGS:
gax ~ # grep ^CFLAGS /etc/make.conf
CFLAGS="-03 -mcpu=athlon-xp -pipe -fomit-frame-pointer"
gax ~ # CFLAGS="-mcpu=athlon-xp -pipe -fomit-frame-pointer" /usr/bin/emerge mjpegtools

This time, it worked fine.

Reproducible: Always
Steps to Reproduce:
1. add -O3 to your CFLAGS
2. emerge mjpegtools (version 1.6.1.90-r2)

Actual Results:  
Error message from emerge.

Expected Results:  
Install :)

Sorry, I forgot to add gcc's version:
gax ~ # gcc --version
gcc (GCC) 3.3.2 20031218 (Gentoo Linux 3.3.2-r5, propolice-3.3-7)

BTW this is linux-2.6.1, although this is probably irrelevant.

[Comment 2 Patrick Kursawe (RETIRED) 2004-03-24 23:45:46 UTC]

Yes, this is irrelevant, since you used -03 (zero three) instead of -O3 (letter O three) which is indeed an unknown option for gcc (and by the way often worse than O2 on modern processors since it tends to increase code size).
