Bug 102873 – svgalib causes emerge -e system to fail on 2005.1 stage1 & 2 installs when svga USE flag is set. is due to the lack of kernel headers

• Product: Gentoo Linux
• Status: RESOLVED DUPLICATE

[Description chrisp 2005-08-17 10:29:34 UTC]

svgalib requires the kernel headers to compile and will fail on any emerge done before emerging kernel 
sources for any stage 1 or 2 install.  This is _very_ confusing for new to novice users as the reason for 
failure is not readily apparent.   It's probably not too common for new users to set svga, but in one 
instance I have given a new user my USE flags that contained svga and heard back that the install kept 
failing.  Even for advanced users, it's always annoying to have to redo 'emerge -e system'

Reproducible: Always
Steps to Reproduce:
1.  begin stage1 install, using svga as a USE flag
2.  continue install and do: emerge -e system
3.  merge will fail on svgalib

Actual Results:  
non-obvious compilation error on svgalib, system failed to merge

Expected Results:  
either the svga flag should be filtered, or a warning should be issued stating to chose your kernel source 
and emerge it (this brings in a lot of other sytem dependencies though).  a warning could also be put into 
the documentation saying what use flags will pull in packages that require kernel sources.

emerge info taken after successfull emerge -e system (after setting -svga):

Remove the use flag, this can't be fixed. That's why it was removed from default
use flags.
