Description Piyush Bhoot 2015-09-25 14:12:13 UTC

Description of problem:
Applications breaks when certain software collections are enabled

Version-Release number of selected component (if applicable):
scl-utils-20120927-27.el6_6.x86_64

How reproducible:
Always

Steps to Reproduce:
1. # evince dbg.pdf
(This should work)

# source scl_source enable python27

Actual results:
# evince dbg.pdf
(This should fail with the message unable to open document: File type application/octet-stream type (application/octet-stream) is not supported)

Expected results:
File should open


Additional info:

# unset XDG_DATA_DIRS
# evince dbg.pdf
(Should work now)

To workaround this issue, a symbolic link should be created between /usr/share/mime/packages/ and /opt/rh/python27/root/usr/share/mime/packages directories by executing below command :

ln -s /usr/share/mime/packages/ /opt/rh/python27/root/usr/share/mime/packages

and then execute 'update-mime-database /opt/rh/python27/root/usr/share/mime'

It should not set XDG_DATA_DIRS if /opt/rh/python27/root/usr/share/ does not contain required files.

We have following strategy 

/opt/rh/devtoolset-3/root/usr/lib/gcc/x86_64-redhat-linux/4.9.2/libstdc++.so

/opt/rh/devtoolset-3/root/usr/lib/gcc/x86_64-redhat-linux/4.9.2/libstdc++.so: 
ASCII C program text

/* GNU ld script
   Use the shared library, but some functions are only in
   the static library, so try that secondarily.  */
OUTPUT_FORMAT(elf64-x86-64)
INPUT ( /usr/lib64/libstdc++.so.6 -lstdc++_nonshared )

Comment 2 Ľuboš Kardoš 2015-09-25 14:25:49 UTC

This has to be fixed in enable scriptlet of the collection. See also bug 1252845

Comment 5 Branislav Náter 2016-04-14 17:52:12 UTC

Fix is incorrect. There are two curly brackets in the enable script instead of just one.

# rpm -q python27
python27-1.1-23.el6.x86_64
# scl enable python27 bash
# env | grep XDG
XDG_DATA_DIRS=/opt/rh/python27/root/usr/share/usr/local/share:/usr/share} <-----

# cat /opt/rh/python27/enable | grep XDG
export XDG_DATA_DIRS=/opt/rh/python27/root/usr/share${XDG_DATA_DIRS:-/usr/local/share:/usr/share}} <------

Comment 7 Branislav Náter 2016-04-20 11:05:14 UTC

Reproduced on python27-1.1-17.el6 and python27-1.1-20.el7:
evince even did not start for rhel-7 ((evince:2118): GLib-GIO-ERROR **: No GSettings schemas are installed on the system) and doesn't display document for rhel-6.
                                                                                 
Verified on python27-1.1-24.el6 and python27-1.1-24.el7:                         
evince is able to display pdf document correctly on rhel-6 and rhel-7.

So customer issue is solved but unfortunately I've spotted another issue:

# env | grep XDG_DATA
XDG_DATA_DIRS=/opt/rh/python27/root/usr/share/usr/local/share:/usr/share

First two paths are not separated using colon. It should be:
/opt/rh/python27/root/usr/share:/usr/local/share:/usr/share
                               ^

Comment 9 Branislav Náter 2016-05-12 12:07:17 UTC

Verified on python27-1.1-25.el6 and python27-1.1-25.el7

evince works with collection enabled, path are set correctly.

# env | grep XDG
XDG_DATA_DIRS=/opt/rh/python27/root/usr/share:/usr/local/share:/usr/share
