Description Bernardo S. A. Silva 2003-01-02 09:10:51 UTC

Hi everyone,

 First, the gcc-config script is working perfectly. Great work!
 But when I wanna to use gcc-config to force some ebuild to compile with gcc2
(like mozillla, to work with java plugin), I have to reopen the /etc/make.conf
to change my CFLAGS that are incompatible with it:

 CFLAGS="-march=athlon-xp -mmmx -m3dnow -msse ...etc..." to:
 CFLAGS="-march=i686 ...etc...".

 If the GCC2 profile has a CFLAGS variable that subscribe the /etc/make.conf
variable, or if the /etc/make.conf has two variables like:

 CFLAGS-GCC3=...
 CFLAGS-GCC2=...

 It will be good. But, it is only a sugestion.

   Thanx a lot... Bernardo S. A. Silva

I guess it would be cool if we can pass options to gcc config through portage:

  emerge --gcc-config "--convert-cflags-gcc2 i686-pc-linux-gnu-2.95.3" mozilla

(ok, the --convert-cflags-gcc2 is not there yet ...)

And then ebuild.sh will run just after it sourced /etc/profile.env:

  eval `gcc-config --print-environ --convert-cflags-gcc2 i686-pc-linux-gnu-2.95.3`

Comments ?  Dont know if the form are ok ..

Yes, im spamming, but I have been contemplating this for a long time.

Nick, if you need me to write a patch, and get these good people to test it,
let me know.  Also, just let me know why will be accepted flags and behavior ...

Comment 5 Bernardo S. A. Silva 2003-01-05 10:39:02 UTC

The convert flags is an good idea. But, when implemented, it is good if it is
transparent. Like an implicit conversion on emerge script or something like that.

Comment 6 Bernardo S. A. Silva 2003-10-26 11:11:24 UTC

This is not important...
