1 As promised, here is the slimmed down version of the Prefix quiz. As
2 requested, I'll post the answers on -core.
5 Prefix development quiz (Zero taste)
7 ** when porting ebuilds for Gentoo Prefix, one will get confronted with
8 certain problems, these two questions hint at such problems **
10 4. Package Y has a configure script that's just being run by econf.
11 You just added Y and now try to install it. What do you watch
12 for?
13 5. configure for package Z says "checking for libc... /lib/"
14 how do you proceed?
16 ** working with Gentoo Prefix requires to have basic knowledge about how
17 various Prefix components interact with the system **
19 1. Which variables are specific to Prefix? What does each of them
20 represent? How can you construct them?
21 2. An ebuild in the main tree does
22 emake DESTDIR="${D}" somedir="${D}/somedir" otherdir="/other" install
23 what would you change to make it correct in Prefix?
24 3. Same question for
25 insinto /usr/bin
26 8. An eapify-ed ebuild contains if [ ${EROOT} = "/" ], is this correct?
28 ** once potential problems can be recognised, solutions to them have to
29 be implemented **
31 4. A configure scripts checks for gawk and finds /usr/bin/gawk, how do
32 you proceed? What if it checks for a specific program via a
33 --with-program flag?
34 5. A package installs objects or libraries that depend on other shared
35 libraries. What do you check? What if the package installs some
36 scripts?
37 6. You fire up $EDITOR which you just emerged, and notice that you get
38 different colours than $EDITOR in regular Gentoo. What went probably
39 wrong?
41 ** optional: Gentoo Prefix is different from other offset-based
42 solutions in a number of ways. The following question reveals the
43 most(?) developer-friendly difference **
45 7. References to dynamic libraries in Prefix are sort of "fixed" to find
46 the Prefix libraries. Why is this done?
