Hello,

Thanks for your contribution!

Your patch (and the previous one) lacks a Signed-off-by.

This is most likely incorrect. BR2_PACKAGE_FREETYPE indicates that the
target freetype is available, it has nothing to do with whether
host-freetype should be used or not.

This line is incorrect, because it changes the CXXFLAGS globally, for
all packages.

Weird how this is formatted. In any case, all patches should have a
description and Signed-off-by line.

Could you explain what you are trying to achieve ?

Please send your e-mails to the mailing list directly. If you don't

Thanks!

Hi Thomas,

the ghostscript isn't compiled against the freetype lib although it is
switched on. Ghostscript doesn't support cross compiling and the old
freetype sources within ghostscript are deleted. So the headers of the
freetype package must be included, and the ghostscript configure is changed
to use the host pkgconfig.
