Het lijkt er op dat we libsdl nodig zijn als dependency. (best logisch ook). We zetten #NEED:libsdl in de slackbuild en proberen het nog eens. Deze heeft zeer veel diepere dependencies, dus het duurt even om de buildroot te vullen. Koffie dus! Sterker nog het is zaterdag, dus even een lekker Bitburger biertje er bij:

checking for SDL - version >= 1.2.10... no
*** Could not run SDL test program, checking why...

psy npl # ./findpkg libsdl

Aiiii...het werkt nog niet, we hebben versie 1.2.11, dus het moet werken zou je zeggen. We duiken de buildroot in en gaan op onderzoek uit:

psy npl # chroot ../builder/buildroot0/

We zien in de config.log, een stuk vanaf het einde van de file dat libSDL.so de dependency libdirectfb nodig is. Vreemd, want deze moet automatisch geinstalled worden. We onderenzoeken libSDL.so wat beter:

Shit...libsdl is gelinked tegen libdirectfb 0.9, terwijl libdirectfb 1.0 geinstalleerd is! Dit betekend dat iemand ooit een nieuwe versie voor libdirectfb gebuild heeft en dat libsdl niet gerebuild is. We kijken in libsdl en veranderen de #NEED in #DEP. Zo zorgen we ervoor dat libsdl automatisch gerebuild word bij een andere versie van libdirectfb. Ook zetten we in ons eigen script een #DEP, zodat we zeker weten dat deze ook rebuild als libsdl ooit vernieuwd word..

We doen een rebuildcheck op libsdl_image, waardoor libsdl nu automatisch gerebuild word en daarna libsdl_image nogmaals. (hopenlijk;). Dit gaat allemaal nog langer duren, dus we lurken rustig van ons bier en wachten af:

psy npl # mcedit mediabox/libsdl/libsdl.SlackBuild

All rebuilds completed.

Het rebuilden van libsdl EN libsdl_image gaat nu goed! Het probleem lag dus bij een ander pakketje. We zijn er in geslaagd om libsdl_image simpelweg te builden door het standaard buildscript te gebruiken met 1 DEP er in voor libsdl.

We bekijken de inhoud van het pakketje:

psy npl # tar -tzf mediabox/libsdl_image/libsdl_image.pkg
./
install/
install/doinst.sh
usr/
usr/lib/
usr/lib/libSDL_image-1.2.so.0.1.5
psy npl # tar -tzf mediabox/libsdl_image/libsdl_image_dev.pkg
./
usr/
usr/lib/
usr/lib/libSDL_image.la
usr/lib/libSDL_image.a
usr/include/
usr/include/SDL/
usr/include/SDL/SDL_image.h

Dit ziet er goed uit. Tijd om toe te voegen aan SVN:

psy npl # svn add mediabox/libsdl_image

Zo, nu kunnen we weer verder met openmsx. En het mooiste is: ons biertje is nog niet eens op!
