MinGW GDC updates
A new binary has been posted.  This contains GDC master up to Nov. 28th.

There's one annoyingly significant bug that I am aware of regarding 
exceptions.

Any uncaught exceptions will result in an infinite loop eventually 
dieing due to stack overflow.  However, this is only a minor annoyance 
and something to keep in mind when using GDB.

Installation instructions:

1. Download and install TDM 4.6.1 MinGW64( To a dedicated directory for 
GDC )
2. Extract the downloaded archive into the base of the newly installed 
TDM install.

If you've done this before, you can just do step 2.

You'll need to pull it from the archives.

Hi Daniel,

Thank you for your work so far.

I ran into some issues after following the installation 
instructions. I was getting the following error:

gdc: fatal error: -fuse-linker-plugin, but liblto_plugin-0.dll 
not found

I tracked down the problem to the TDM-GCC installer linked in 
your post. It appears that even though the installer is from an 
older version, it will still download the latest one (4.7.1), and 
not even give you an option to select an older version.

Downloading the 4.6.1 archives and unpacking them manually took 
care of the problem. Here is what I had to download and unpack to 
get everything working:

GCC core: 
http://sourceforge.net/projects/tdm-gcc/files/TDM-GCC%204.6%20series/4.6.1-tdm64-1/gcc-4.6.1-tdm64-1-core.tar.lzma/download
GCC C++: 
http://sourceforge.net/projects/tdm-gcc/files/TDM-GCC%204.6%20series/4.6.1-tdm64-1/gcc-4.6.1-tdm64-1-c%2B%2B.tar.lzma/download
MinGW runtime: 
http://sourceforge.net/projects/tdm-gcc/files/MinGW-w64%20runtime/GCC%204.6%20series/mingw64-runtime-tdm64-gcc46-svn4483.tar.lzma/download
GDC: 
https://bitbucket.org/goshawk/gdc/downloads/gcc-4.6.1-tdm64-1-gdc-20130108-D2.060.7z

By the way, I noticed this in README-gdc-mingw.txt:

> Includes D1 and D2 compilers.  Defaults to D1,
> D2 can be used by specifying -v2.
> -v2 must be used if GDC is used for linking.

And in the gdmd perl script:

>     } elsif ( $arg =~ m/^-v1$/ ) {
>         push @out, '-fd-version=1';

gdc doesn't seem to accept neither -fd-versionX nor -vX switches, 
so I assume the above are both outdated.

There's an option at the start [check for updated files]. I remember
having to unselect that to install an older version. Don't know if it
still works.

Ahh... thanks, I completely missed it.

Thanks for bringing that to my attention.  That file is need of an 
update as I've removed that several months back.

Re: MinGW GDC updates
Is it possible now to rebuild druntime and phobos without building the 
compiler from source first?

If not where are the most up to date instructions for building GDC on 
windows?

Kind Regards

Re: MinGW GDC updates
Hi,

I'm sure you've seen it anyway, but just in case, I wanted to draw your 
attention to a 32-bit TLS bug I think I found, which only seems to 
affect this version.

Details are in the "Can GDC make DLLs?" thread: 
http://forum.dlang.org/thread/kgb15b$2o05$1@digitalmars.com#post-kgbdu5:24b2p:241:40digitalmars.com

There's a crash in the 32-bit build of a quick non-DLL test I did too, 
but it looks different - it's in the GC thread. I have no idea if it's 
the same bug or not.

Thanks for the hard work though - I'm very happy that GDC exists :)

Hi Daniel,

I'd like to try building GDC for MinGW-64 myself, so I could 
contribute patches.
Are the instructions at http://gdcproject.org/wiki/MinGW64 up to 
date?
I noticed it mentions some patches attached to a BitBucket 
ticket, but the ticket now points to a patch queue, and GDC 
development had since moved to GitHub.

The instructions are not up to date.  The patch queue was merged into 
the mingw branch at https://github.com/venix1/GDC.git

I've been working on doing a fresh install in order to update the 
instructions.
