xcb-proto + python3 fails

[thomas]

There seems to be an issue in xbc-proto (v1.9) when only Python3 (v3.3) is installed:

Andy from ArchLinux has reported this issue upstream (​http://lists.freedesktop.org/archives/xcb/2013-November/008789.html) No answer yet.

[Fernando de Oliveira]

Please, try the attached patch (only for Python3).

[Wayne Blaszczyk]

The following worked for me (from Gentoo):

rm -f py-compile
autoreconf -fi
./configure --prefix=/usr
make install

[Fernando de Oliveira]

Thanks, Wayne. I was already editing, when you posted that alternative solution.

The patch should work also for Python2, but not necessary, thus, introduced it as required just for python2.

I was waiting for a reply from Thomas. Perhaps he installed Python2. But could test with

PYTHON=/usr/bin/python3 ./configure $XORG_CONFIG

Fixed at r12279.

[Wayne Blaszczyk]

Can you let me know if you can build libxcb. I'm having issue with this and it might be related back to xcb-proto.

[Wayne Blaszczyk]

It is related to xcb-proto. Not sure if a new ticket should be raised, but the above was fixed by the following (again from Gentoo)

sed -i -e 's/\t/    /' xcbgen/xtypes.py

[Fernando de Oliveira]

Thanks. I was investigating, but like your solution. Please, open a ticket. If you wish, accept and fix it. I miss your editions in BLFS, would like to have you back editing. Speaking just for me, do not know what other editors think. Would like your help with gnome to bring it back as I asked two days ago in -dev.

[Fernando de Oliveira]

Before comment 6 and 7, I was writing ths on. It is not anymore relevant, but can explain what I meant about investigating.

Yes, I have built libxcb-1.9.3, after xcb-proto built with the patch, and Xorg works fine.

Did not pass PYTHON=/usr/bin/python3, just used instructions as in the book. I am investigating further, just noticed it is using python 2 and python 3.

Do you have both installed? Did you use that solution from gentoo passing PYTHON=/usr/bin/python3 for xcb-proto?

Replying to wblaszcz:

It is related to xcb-proto. Not sure if a new ticket should be raised, but the above was fixed by the following (again from Gentoo)

sed -i -e 's/\t/    /' xcbgen/xtypes.py

Only now I understood. Was doing other things and only replying. This needs to be fixed also in xcb-proto, not libxcb as I thought at the beginning. I will do it. Thanks.

[Fernando de Oliveira]

Thank you versy much, Wayne!!!

Hope it is fixed at 12283.

[Wayne Blaszczyk]

To comment 6, I re-edited my comment to include 'It is related to xcb-proto' to make it clear. You must have read my comment prior to my edit.

To comment 8, at the time, I only had Python3 installed and I did not pass PYTHON=/usr/bin/python3.

To comment 7, there are to reasons why I haven't been contributing. 1) I have limited time. 2) I use systemd.
