I've been looking at the license.bbclass code for other reasons and it
has a few issues. I suspect not many people are actually enabling the
separate license packages, I don't think its enabled anywhere in our
automated testing either.
I think we'll have to have some code which translates "XXX" into "XXX-
license-text" for the license of ${PN}-lic.
Something like:
def convert_to_license_texts(d):
licenses = d.getVar("LICENSE")
ret = []
for x in licenses.split():
if "|" in x or "&" in x:
ret.append(x)
else:
ret.append(x + "-license-text")
return ret.join(" ")
LICENSE_${PN}-lic = "${@convert_to_license_texts(d)}"
(admittedly completely untested)
Ideally we'd have some mapping to convert the GPL/LGPL entries to FSF-
license-text and simplify out any |/& expressions but for now the above
is probably good enough.
Cheers,
Richard
