BUG: pango 1.12.0 various problems

[vincent-opdarw@…]

/opt/local/etc/pango/pango.modules is empty (well, it only contains comments). The probable fix is to replace 1.4.0 by 1.5.0 in the Portfile since "port contents pango" shows that the modules are in /opt/local/lib/pango/1.5.0/modules/.

[vincent-opdarw@…]

I've tried and this fills up the /opt/local/etc/pango/pango.modules file as expected (like previous versions), but pango still doesn't work. After a clean rebuild of liferea, I get:

prunille:~> liferea Neither Mozilla nor Firefox is available... A stale lockfile has been found, and was deleted. No browser module configured! trying to load browser module GtkHTML2 (liblihtmlg.so)

(liferea-bin:10479): Pango-WARNING : No builtin or dynamically loaded modules were found. Pango will not work correctly. This probably means there was an error in the creation of:

'/opt/local/etc/pango/pango.modules'

You should create this file by running pango-querymodules.

(liferea-bin:10479): Pango-WARNING : pango_shape called with bad font, expect ugly output

and this ends with a bus error. Any idea?

[vincent-opdarw@…]

Oh... A ktrace/kdump is interesting:

The line

10680 liferea-bin NAMI "./opt/local/etc/pango/modules/pango.modules"

is wrong (see the dot before the path).

/opt/local/etc/pango/pangorc has the same problem:

ModuleFiles = ./opt/local/etc/pango/modules/pango.modules

(ditto in the comments).

Assigning to maintainers.

pango-querymodules did not help, even

cd /opt/local/lib/pango/1.5.0/modules/ Bilbo:/opt/local/lib/pango/1.5.0/modules yves$ sudo pango-querymodules * > /opt/local/etc/pango/pango.modules

does not help

[vincent-opdarw@…]

(In reply to comment #4)

Bilbo:/opt/local/lib/pango/1.5.0/modules yves$ sudo pango-querymodules * > /opt/local/etc/pango/pango.modules

AFAIK, when you use a redirection like this, the file is opened by the shell, i.e. before the sudo takes place. This means that you probably don't have the permissions. Try without the redirection and you'll see that the output is correct.

[yves@…]

No the redirection works, but it is probably because I previously did it using a tmp file and then a forced copy (I did get into troubles with this, thanks for the explanation)

anyway, etc/pango/pango.modules is the same as stdout

[vincent-opdarw@…]

To summarize, there are currently two problems with the current port:

1. An incorrect version in a path in the Portfile, with the consequence that modules are not provided to pango-querymodules.

2. The problem I've described in comment #2. Perhaps some problem with these lines?

reinplace "s|
./|${prefix}/etc/pango/|g" \

${destroot}/${prefix}/etc/pango/pangorc

reinplace "s|
./|${prefix}/etc/pango/|g" \

${destroot}/${prefix}/etc/pango/pangox.aliases

Also, doesn't the configure script have a --sysconfdir option that could be used instead of the above rewriting?

[mij@…]

I'm looking at this, but I've got to head out to work so I probably won't have time to test it until tonight when I get home.

[mij@…]

Try this patch: ​http://soupnazi.org/files/pango-Portfile.diff. I'd have attached it, but bugzilla seems to be having fits when I try to do that :\ If it works, let me know and I'll check it in.

Try this patch: ​http://soupnazi.org/files/pango-Portfile.diff.

To make it more reliable, you should write:

reinplace "s|
.
./modules/|${prefix}/etc/pango/|g"

otherwise the dot matches any character (not just a dot). Moreover how about removing the

reinplace "s|
./|${prefix}/etc/pango/|g"

${destroot}/${prefix}/etc/pango/pangox.aliases

since it seems to be useless (here no paths appear in this pangox.aliases file) and may also be wrong anyway.

I've tried with my suggestions and Liferea now works correctly.

[mij@…]

Committed with your changes. Thanks!
