How to build a package yourself, or modify it between unpacking and merging
The following is an old FAQ which has been officially removed for a long time.
I want to perform the ./configure step myself. Can I?
Yes, but it is not trivial, and the next method only works when it is a simple ebuild (i.e. just ./configure and make && make install). Be sure to read the ebuild itself to see how Gentoo handles it.
Start with unpacking the ebuild: ebuild /usr/portage/<category>/<package>/<ebuild> unpack.
Next, go to /var/tmp/portage/<package>-<version>/work. Inside it you'll find the unpacked sources. Execute the steps you need to perform to configure and compile the package.
When finished, execute touch /var/tmp/portage/<package>-<version>/.compiled to trick Portage into thinking it configured and compiled the package. Then finish up with ebuild /usr/portage/<category>/<package>/<ebuild> merge.
Diff between make.conf on two systems
Since the USE flags are in a sort of paragraph rather than one-per-line, diff is hard. Here's a perl program to help:
#!/usr/bin/perl
use IO::Handle;
$numArgs = $#ARGV + 1;
if ($numArgs > 0)
{
open (MCONF, $ARGV[0]) or die "can't open $ARGV[0] : $!";
}
else
{
open (MCONF, "/etc/make.conf") or die "can't open /etc/make.conf: $!";
}
my $isuse = 0;
while ( $line = <MCONF> )
{
if ($line =~ /USE=\"/)
{
$isuse = 1;
}
if ($isuse)
{
if ($line =~ /\"$/)
{
$isuse = 0;
}
$line =~ s/USE=\"//;
$line =~ s/\"//;
$line =~ s/\n//;
$line =~ s/\s+/\n/g;
print $line;
}
}
