Bug 14808 – GnuCash 1.6.8 compilation breakage

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Per Cederberg 2003-01-30 17:32:50 UTC]

I experience a compilation breakage when compiling GnuCash 1.6.8 with gcc 3.2.1
(r6). I have a recently installed 1.4.rc2 system with all installed packages up
to date. The error printed is attached below. No errors were reported previous
to this one (as far as I could see):

--- END LISTING ---

The probable reason for the breakage are my optimization settings:

CFLAGS="-O3 -mcpu=i686 -march=i686 -funroll-loops -frerun-cse-after-loop
-frerun-loop-opt -pipe"

When removing all the -fxxx settings and using -O2 the compilation works:

CFLAGS="-O2 -mcpu=i686 -march=i686 -pipe"

I suspect that the gnucash ebuild should be modified to filter out the offending
optimization setting(s) (whichever that may be). Perhaps the gcc folks should
also be informed about the error (if they support -O3 optimizations).

Leonardo: use the flag-o-matic to change and remove unwanted flags

[Comment 2 foser (RETIRED) 2003-03-03 19:38:09 UTC]

added some more filter magic, should be safer now.

[Comment 3 Aric LeDell 2003-03-16 17:04:12 UTC]

Typo in fix from comment #3; the ebuild in portage has a syntax error on line 38:
     filter-flag "-O3" "-O2"
needs to be
     filter-flags "-O3" "-O2"

I'm not sure if I should reopen this bug (bugzilla doesn't seem to let me), 
or just rely on Martin Holzer to change the ebuild.

P.S., this typo was propogated to the gnucash-1.8.x ebuilds proposed in 
another bug#

fixed in cvs

thx
