Mono 4

Summary

Update the Mono stack in Fedora from 2.10 to 4.*

Owner

Current status

Detailed Description

Support for Mono versions 3.0 and 2.10 is been discontinued. No further development of bug fixing is planned for those branches. Mono 4 is the active branch an have many improvements . See upstream notes http://www.mono-project.com/docs/about-mono/releases/4.0.0/

Mono require it self to build. Actual version 2.10.8 is to old to build version 4 that require at less version 3.4. At the moment on copr we use monolite a little version of mono compiler shipped in the tarball for first build time.

We have two option to upgrade:

  • Upgrade mono to version 3.4, then to version 3.12 and then to version 4.0.1 on rawhide (actually 3.4 don't build on rawhide this need fixed)
  • Make a one time exception of the rule for build mono 4.0.1-1 using monolite, later make mono depend again on it self and rebuild mono 4.0.1-2 using mono-4.0.1-1

Benefit to Fedora

Fedora aims to showcase the latest in free and open source software - we should have the most recent release of Mono 4.0.1

It will have the ability to run cross-platform applications that require compatibility with Microsoft. Net Framework 4.5

Scope

  • Proposal owners:

Update mono spec and build in copr and/or koji until is ready.

  • Other developers:

See Upgrade/compatibility impact and Dependencies section

  • Release engineering: None
  • Policies and guidelines: None

Upgrade/compatibility impact

Mono 4 includes most of the features of Mono 2.10 and Mono 3 branch.

The profiles 2.0, 3.5 and 4.0 will not be build any more in favor of profile 4.5

Many packages may need to be revised, updated or rebuilt because Mono 4 require that all application use target 4.5. In general is a simple task to sed .sln, .cproj, configure, configure.in, configure.am, Makefile, Makefile.in, Makefile.am for use mcs instead gmcs and change profile < 4.5 to 4.5. The files to sed change depending in what form is distributed the sources. In most off the cases only configure files need sed. A few package work without changes like gnome-subtitle or pinta

The fixes is work in progress on https://github.com/elsupergomez/lbs-mono-fedora and https://github.com/tpokorra/lbs-mono-fedora


How To Test

Interested testers do not need special hardware. Take a given Mono application and test it against the Mono at this copr repo and verify it works:

* http://copr.fedoraproject.org/coprs/tpokorra/mono/

Any issue will be reported in github https://github.com/elsupergomez/lbs-mono-fedora or https://github.com/tpokorra/lbs-mono-fedora

User Experience
