[ptxdist] Build system doesn't find host compiled packages

[ptxdist] Build system doesn't find host compiled packages

[jean-philippe francois]

Hi,

I installed 2015.06.0 today, and my project (migrated from a 2011.12
project) now stops when compiling host-fakeroot with the following
message :

In file included from libfakeroot.c:223:0:
wrapped.h:126:27: error: unknown type name 'cap_user_header_t'
 extern int (*next_capset)(cap_user_header_t hdrp, const cap_user_data_t datap);

It is my understanding that this message comes from a missing libcap,
but host-libcap has been succesfuly build.
I have had a similar problem with host-acl that could not find the
just built host-attr. This previous problem was solved by installing
the libattr-devel package,  but the point of ptxdist is precisely to
avoid installing system packages.

Can you help me debug this issue ? I suspect I forgot something when
migrating from the old project.

Thank you,
Jean-Philippe François

After a ptxdist clean, going straight to ptxdist kernelconfig is not
the right thing to do !
Starting with ptxdist go instead.
Sorry for the noise.

Fakeroot's dependency to LIBCAP is part of PTXdist since commit 
0f43c449de4a6b769d5b49720c48bc57716c1b8b. So I wonder why it fails at your 
side, because it is part of the June release.

Hmm, this should work as expected.

Sounds more like a workaround, not a solution.

Please stay tuned.

It really should... but it doesn't. You found a bug in PTXdist. It also crashes 
here, and only if you start a "ptxdist kernelconfig" on a clean BSP.

You must continue to use this workaround, until we find a solution.

Commit 553e0fea17507633ee53e9e0b1d3da67bcf0b3ab in ptxdist master fixes this 
issue. Thanks for reporting the bug.
