host-librsvg install a gdk-pixbuf module (aka plugin). As such, it needs
to update [0] the modules cache (a kind of registry of which modules are
installed and what the can handle). To that effect, it calls the utility
gdk-pixbuf-queryloaders, which generates the cache of existing modules.
gdk-pixbuf-queryloaders, from the gdk-pixbuf package, has been
configured to be relocatable. However, it still embeds the path to where
it was instaled, and thus where to look modules from. If it is run from
its install location, then gdk-pixbuf-queryloaders looks modules in that
location, and generates a modules cache with relative paths; otherwise,
it still looks at that location, but generates a cache with absolute
paths. In the later case, it will miss the modules that have not been
installed by gdk-pixbuf itself.
In the case of host-librsvg, that will miss the fact that librsvg just
happened to have installed a module. Further down the road, packages
that depend on host-librsvg, will get their PPD prepared, the path fixup
hook run, so that the cache properly points to the current package's
PPD, but the cache will not include the SVG module, which causes
failures to load CVG images:
Can't load file: Unrecognized image file format
So, we need to tell gdk-pixbuf-queryloaders where the module path is,
which restores the relativity of the paths it reports, by specifying the
modules path pointing to the current package's PPD, passed in the
environement variable GDK_PIXBUF_MODULEDIR.
We need to do that at install time, so that the SVG module is properly
listed in the cache, so that dependees can use it.
A temporary cache is also generated at build time, but its usefullness
is dubious; it seem to only be used by the test tool, which we do not
run. However, for consistency-sake, we also fix that.

[0] This will trigger file-overwrite detection in the future... But we
currently do not have infrastructure to properly handle such a cache.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
