MinGW GCC 4.8

Summary

Update the mingw-gcc cross-compiler to gcc 4.8 and rebuild all MinGW packages against it

Owner

Current status

  • Targeted release: Fedora 19
  • Last updated: 2013-01-26
  • Percentage of completion: 50%

Detailed Description

The Fedora MinGW SIG maintains over a large number of packages which allows users to build binaries for the win32 and win64 targets using the mingw-w64 toolchain. One of the goals of the Fedora MinGW SIG is to have the package versions as close as possible to their native counterparts: https://fedoraproject.org/wiki/Packaging:MinGW?rd=Packaging/MinGW#Track_Fedora_native_package_versions As Features/GCC48 gcc 4.8 was accepted as a feature for Fedora 19 we intend to update the mingw-gcc package in Fedora 19 as well to gcc 4.8

Benefit to Fedora

See http://gcc.gnu.org/gcc-4.8/changes.html for the list of changes

Scope

The introduction of mingw-gcc 4.8 can be split in the following sub-tasks:

  • Update mingw-gcc to version 4.8 in a local environment done
  • Perform a test mass rebuild against this updated mingw-gcc package done, results
  • Identify build failures done, results
  • Resolve build failures 2 packages remaining, mingw-qpid-cpp and wine-mono
  • Introduce mingw-gcc 4.8 in rawhide
  • Rebuild all mingw-* packages which depend on libgcc_s_sjlj-1.dll (upstream switched to SEH exception handling for the win64 target by default)
  • Have all other mingw-* packages rebuild by the mass rebuild which will start on February 1 2013

How To Test

User Experience

Dependencies / Affected packages

All mingw-* packages and wine-mono need to be rebuild after mingw-gcc 4.8 is introduced in rawhide.

The list of packages which need to be rebuild directly after the introduction of mingw-gcc 4.8 to prevent broken dependencies are:

These packages need to be rebuild directly because gcc upstream decided to use SEH exception handling by default for the win64 target. The library libgcc_s_sjlj-1.dll is replaced with libgcc_s_seh-1.dll for the win64 target. Therefore all packages which used to depend on libgcc_s_sjlj-1.dll need to be rebuild so they start using libgcc_s_seh-1.dll instead
