Are you sure that's the upstream URL? Isn't t2 yet another embedded
build system?

This is the default, so you can drop this line.

Personally I prefer to not align the '=' signs, but I know we have a bit
of a mix in the tree.

 Carsten> +LIBSVG_SITE            = http://cairographics.org/snapshots/
 Carsten> +LIBSVG_DEPENDENCIES    = libxml2
 Carsten> +LIBSVG_INSTALL_STAGING = YES
 Carsten> +LIBSVG_LICENSE         = LGPLv2

grep -rls 'any later version' src | wc -l
24

It looks to be LGPLv2+.


 Carsten> +LIBSVG_LICENSE_FILES   = COPYING
 Carsten> +
 Carsten> +$(eval $(autotools-package))

It looks good, but it doesn't work:

checking for ANSI C header files... (cached) yes
checking whether libexpat is requested... no
./configure: line 20639: /home/peko/source/buildroot/output/host/usr/bin/pkg-config: No such file or directory
*** Your version of pkg-config is too old. You need version 0.9.0 or newer.
*** See http://www.freedesktop.org/software/pkgconfig
configure: error: Library requirements (libxml-2.0 >= 2.4.7 ) not met; consider adjusting the PKG_CONFIG_PATH environment variable if your libraries are in a nonstandard prefix so pkg-config can find them.

So you atleast need host-pkgconf as a dependency. It looks like it can
work with expat instead, so you could drop the hard dependency on
libxml2, but that is not really critical.
