This message is a reminder that Fedora 21 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 21. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '21'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 21 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

This bug appears to have been reported against 'rawhide' during the Fedora 24 development cycle.
Changing version to '24'.

More information and reason for this action is here:
https://fedoraproject.org/wiki/Fedora_Program_Management/HouseKeeping/Fedora24#Rawhide_Rebase

Version 2016 is out now ...

And on F25 we still have 1.3.2.

This bug appears to have been reported against 'rawhide' during the Fedora 26 development cycle.
Changing version to '26'.

The package libGLEW has been updated to provide libGLEW.so.2.0.
Hence on Fedora 26 installation of meshlab fails.

$ sudo dnf install -y meshlab
Last metadata expiration check: 0:32:29 ago on So 09 Jul 2017 13:50:36 CEST.
Error: 
 Problem: conflicting requests
  - nothing provides libGLEW.so.1.13 needed by meshlab-1.3.2-10.fc25.i686
  - nothing provides libGLEW.so.1.13()(64bit) needed by meshlab-1.3.2-10.fc25.x86_64

Note that I have been trying to build the 2016.12 version an the build is failing with plenty of errors. Each time I fix one, another one raises.

Not related to this bug at all, but I'll have a look.

See https://bugzilla.redhat.com/show_bug.cgi?id=1439673

thank you for your effort

So, what is going on with meshab for F26?  Considering this bug and bug 1439673, I can't tell.

I was going to upgrade to F26 yesterday, but now I'm waiting, since I occasionally need meshlab for first validation of 3D print files.  It's not clear how to react to these bugs reports as a user.

The situation with Meshlab on Fedora 26 is the following:

 * current version of the meshlab package requires old GLEW, thus meshlab need a rebuild to make it installable
 * version 1.3.2 from Fedora fails to build
 * I've been experimenting with version 2016.12 and I get a lot of build errors as well
 * the maintainer of the meshlab package did not respond in couple of years

Meshlab desperately needs someone to make it work. I have the necessary permission to rebuild and/or change the package (= I'm a provenpackager), however I lack the time to fix this. If another packager steps in a provides patches, I can push them and make them happen. Later, we can start the procedure to take over this package, if Eric still doesn't respond.

Patching 1.3.2 just to make it build seems like less work than updating to 2016.12, but updating will be necessary in the future anyway.

Wow, thanks for the detailed explanation.  I understand.  Fair enough; I don't have time to help, either, so no criticism here.

Note that I've just successfully built meshlab 2016.12 outside of RPM environment without current Fedora meshlab patches. Will try to reproduce in RPM.


Two minor adjustment where needed.

sed -i 's/io_TXT/io_txt/' meshlab/src/meshlab_full.pro
mv meshlab/src/plugins_experimental/io_{TXT,txt}

and a patch I'll attach for reference.

Created attachment 1300444 [details]
ReadHeader patch

Note that I fail to build meshalb 2016.12 from RPM and am unsure why is there a failure only in the rpmbuild, probably due to some C++ flags.

This is what i have so far if anyone want's to continue https://github.com/hroncok/meshlab-spec/tree/2016

I've got a package that works. This is an ugly beast, but I'll kick it back to life one more time.

Awesome!
