[PATCH] bitbake.conf: Add sdl-config to HOSTTOOLS

[Ricardo Ribalda Delgado]

Without this patch bitbake cannot find sdl-config

ERROR:  OE-core's config sanity checker detected a potential misconfiguration.
Either fix the cause of this error or at your own risk disable the checker (see sanity.conf).
Following is the list of potential problems / advisories:

libsdl-native is set to be ASSUME_PROVIDED but sdl-config can't be found in PATH. Please either install it, or configure qemu not to require sdl.

First, wrong list, this should go to openembedded-core@ instead of -devel@.

qemu's configure prefers pkg-config instead of sdl-config, so why doesn't
that work for you?

Also note that we don't recommend using host libsdl via ASSUME_PROVIDED
because it's a nightmare to link when we've a sysroot full of
ABI-incompatible libraries.  For example if I try to build on Debian 9
qemu-native with the host SDL it fails at configure time:

| ERROR: User requested feature sdl
|        configure was not able to find it.
|        Install SDL devel

That's a lie, it found it but it wouldn't link:

The host libcaca is linking to the sysroot libncurses, and they're not
compatible.  This is why we moved away from using
ASSUME_PROVIDED=libsdl-native in December 2015.

Ups, my bad. sorry about that. I first tried to bitbake mailing list
but it bounced the mail.

Long story short.

-My configuration was using ASSUME_PROVIDED += "libsdl-native".
probably because I have not changed the local.con for a long while.
-On June I posted https://patchwork.openembedded.org/patch/141112/,
which I wrongly believed that it was merged.
-Also on June Richard posted f0d128ea0dfc2c403ff53a1ac1db3521854b63d5,
that was merged


I am now building without the assume_provided and so far it is working fine.


Maybe we should remove all ASSUME_PROVIDED "libsdl-native" references
on the code?:

ricardo@neopili:/tmp/poky$ git grep ASSUME_PROV | grep sdl
documentation/ref-manual/migration.xml:     ASSUME_PROVIDED += "libsdl-native"
meta-poky/conf/local.conf.sample:# by libsdl-native then uncomment the
ASSUME_PROVIDED line below.
meta-poky/conf/local.conf.sample:#ASSUME_PROVIDED += "libsdl-native"


Best regards!

Making sdl-config available is the wrong solution. See https://bugzilla
.yoctoproject.org/show_bug.cgi?id=11725

I've just closed that bug because I removed the sdl-config check from
sanity.bbclass back in June.
