 |
|
Hi everybody.
I've just finished installing my gnome when I saw that I fogot uncomenting my CXXFLAGS. I've installed all my system (from tarball 1) using the following:
| Code: |
CFLAGS="-march=athlon-xp -m3dnow -msse -mfpmath=sse -mmmx -O3 -pipe -fforce-addr -fomit-frame-pointer -funroll-loops -frerun-cse-after-loop -frerun-loop-opt -falign-functions=4 -maccumulate-outgoing-args -ffast-math -fprefetch-loop-arrays"
#CXXFLAGS="${CFLAGS}"
|
Is there many packages that use cxxflags? Should I recompile them? |

| anything that is written in c++, depending on what you have installed, it might be a lot of packages =) |

thnogueira,
GTK+ / Gnome are written in C, thus not requiring C++ (CXXFLAGS)
Most-Anything involving KDE are written in C++. There are some other apps that use C++ as well, though not sure of them all.
Also gtkmm and gnomemm are C++ bindings for GTK+ / Gnome, respectively.

| What about the system packages? Is there some easy way to know/list which package is written in C++? |

thnogueira,
So far as I'm aware, the base system DOES NOT include ANY C++ (though not 100% certain).
If you are completely uncertain, and don't mind the wait, you could try (with your your updated make.conf):
| Code: |
$ emerge glibc
[...]
$ emerge world -ep
# ===> just to see what will be installed
$ emerge world -e |
This will rebuild EVERYTHING on your system, without the actual re-install and configuration. Of course, the 'wait' will depend on your system, connection, etc...
That's probably your best option if your not sure. But your system will run just fine without these optimizations, so it is not a time CRITICAL issue.
If you have any other questions, just ask.
Good luck.
jasonm.
