Bug 35283 – Changing CFLAGs doesn''t affect compilation output.

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description A J 2003-12-07 12:36:42 UTC]

1. I changed the CFLAGS from 
CFLAGS="-march=pentium4 -O3 -pipe -fomit-frame-pointer"

to 

CFLAGS="-march=pentium4 -ggdb"

yet, I can see the option "-fomit-frame-pointer" when I try to get a debug
version of openssl library. I tried other options as well to get rid of the
"-fomit-frame-pointer" flag and obtain a debug version, but failed to do so.
Also see my post on the forum.

Reproducible: Always
Steps to Reproduce:
1. change CFLAGS=-march=pentium4 -ggdb"
2. emerge openssl-0.9.7c-r1.ebuild
3. 
Actual Results:  
I can still observe the "-fomit-frame-pointer" in the compiler output, even
though its nowhere in the CFLAGS.


Expected Results:  
Compiled without "-fomit-frame-pointer"

Your `emerge --info` output says that you're still using the old setting,
how exactly did you change your CFLAGS ?

[Comment 2 A J 2003-12-07 14:00:37 UTC]

I switched the CFLAGS back to what I usually use. Here's the emerge info output for the flags I used for debug version:

and here's and excerpt from the compilation output, where you can see that -fomit-frame-pointer is still being used as a flag, alongwith -ggdb!

gcc -I../crypto -I.. -I../include  -fPIC -DOPENSSL_THREADS -D_REENTRANT -DDSO_DLFCN -DHAVE_DLFCN_H -DOPENSSL_NO_KRB5 -DL_ENDIAN -DTERMIO -march=pentium4 -ggdb -fomit-frame-pointer -mcpu=pentium -Wall -DSHA1_ASM -DMD5_ASM -DRMD160_ASM   -c -o s3_pkt.o s3_pkt.c

[Comment 3 SpanKY 2003-12-08 06:19:41 UTC]

it's because the openssl package itself puts in that flag

[Comment 4 A J 2003-12-08 08:33:55 UTC]

Oh! So should I just comment out line 52?
sed -i -e "s/-O3/$CFLAGS/" -e "s/-m486//" Configure

I was trying to insert a "-d" in the ./config lines.

Fixed in CVS, thanks!
