Re: [OE-core] [PATCH V2 1/5] dhcpcd: Fix install conflict when enable multilib.

[Alexander Kanavin]

But what is the use case for installing two sets of documentation? Is
it really something that needs to be fixed, or can you simply install
just one of the two packages?

For something as simple as that we should just patch the docs to say
/usr/<libdir>/dhcpcd/dev rather than trying to manage multiple
versions.

If the .pc file doesn't use libdir anywhere, we should just delete that
line. It is being installed into a "noarch" location (datadir) so it
shouldn't be library specific.

Also, we should *never* be putting pkgconfig files under update-
alternatives control!

Richard

I think we should just change the MACHINE, OS, CC and MACHTYPE lines to
something like "<redacted for multilib compatibility>".

So for the correction of this problem, do we need to continue to vote for patch? 
Or accept this patch temporarily, and then roll it back after the bash update?

I'd like to see a patch which fixes the issue properly. If I take this
one temporarily, it is unlikely anyone will then send the correct fix.

RE: [OE-core] [PATCH V2 4/5] xcb-proto: Fix install conflict when enable multilib.

[wangmy]

When libxcb is compiled, it will read libdir from xcb-proto.pc to find the library. 
If delete this line, libxcb will report an error because it cannot find the directory of the library.

I haven't got any better way to solve this problem.

Which library in particular? Can you show the error, and the point in
libxcb's code where it happens?
xcb-proto does not install any libraries, and so there is no reason
for xcb-proto.pc to tell where the libraries are.

RE: [OE-core] [PATCH V2 4/5] xcb-proto: Fix install conflict when enable multilib.

[wangmy]

libxcb needs to find the python package in the path specified by pythondir recorded in xcb-proto.pc. If the libdir line is deleted, libxcb will report an error when compiling:
| Failed to load the xcbgen Python package!
| Make sure that xcb/proto installed it on your Python path.
| If not, you will need to create a .pth file or define $PYTHONPATH
| to extend the path.
| Refer to the README file in xcb/proto for more info.

The file contents after deleting libdir are compared as follows:
@@ -2,10 +2,8 @@
 exec_prefix=/usr
 datarootdir=${prefix}/share
 datadir=/usr/share
-libdir=/usr/lib
 xcbincludedir=${pc_sysrootdir}${datadir}/xcb

Re: [OE-core] [PATCH V2 4/5] xcb-proto: Fix install conflict when enable multilib.

[Alexander Kanavin]

Thanks, in this case the correct fix would be to install xcb-proto.pc
into $libdir, as it is indeed library specific. You need to patch
Makefile.am in xcb-proto's source tree, and offer the patch to
upstream.
