i got dialup modem what should i do to make emerge work during installation time (wud ppp be of some help?)

Hi,
1) CHOST defines what your host is, that is, what is your computer (pentium, P4, alphe, ppc...). This should read : i686-pc-linux-gnu
CFLAGS and CXXFLAGS are the options you give to the compiler (gcc), in order to compile, respectively, C and C++ programs. I too have a P4, mine are :
| Code: | | -march=pentium4 -O2 -pipe -fomit-frame-pointer -msse2 -fforce-addr -falign-functions=4 -fprefetch-loop-arrays -funroll-loops |
2) If you chose gentoo-sources, it's a 2.4 kernel, if you chose gentoo-dev-sources, it's a 2.6 kernel.
3) Your NIC, and soundcard should be configured by recompiling the kernel with the appropriate options. Emerge has nothing to do with it.
4) You can set up your video card two ways :
- Use the X drivers, which is called nv (nothing to emerge, just specify nv in the Driver option of the Device section of the X config file).
- Use the nvidia proprietary driver, you'll have to emerge nvidia-kernel and nvidia-glx, and put "nvidia" in the Driver option of the Device section of the X confg file. The nvidia driver is an independent module that you will have to load manually, at least the first time. Contrary to the nv driver shipped with X, it supports hardware acceleration.

No person new to gentoo should be using those options though

Apart from emerging the drivers, emu10k1 for example

Only if you're using a 2.4 kernel. The soundcard drivers are already there in the 2.6 kernel.

Sorry, I tend to think everyone uses a 2.6 kernel, that's a prejudice !  So yeah, he would have to compile the emu10k1 driver or alsa if he wants his soundcrad to work with a 2.4.
Btw, what's wrong with my CFLAGS ? Everything compiles without a problem (to the notable exception of crypto++, for which I have to revert back to the pentium3 settings).
