After a long wait and many unexpected delays, there is finally going to be a released version of LDC, the LLVM D compiler, again! I'll keep this post short and (hopefully) sweet, a more detailed announcement will follow when the release is actually out:

Right now, we are in the final stages of testing. You can help by downloading a beta version and evaluating it on your system and your projects. The binary packages linked below are self-contained (»DMD-style«) packages and do not require any setup.

Alternatively, you can easily build LDC from source yourself, see http://ldc-developers.github.com for instructions. Currently, this is also required if you want to use LDC as a D1 compiler, but if there is demand, D1 binary packages will be provided for the release.

LDC 0.10.0 is based on the latest currently released DMD versions (i.e. 2.060 for D2, 1.075 for D1), and with a few known exceptions (x86_64 D vararg handling, exception chaining), passes the DMD/druntime/Phobos test suites as part of the CI runs. There are some open bugs at the GitHub bug tracker (https://github.com/ldc-developers/ldc/issues?state=open); if you run into any other issues, please report them there.

As far as this release is concerned, our plan is to push it out together with the LLVM 3.2 release during the coming weekend, i.e. on Dec 16. If no truly critical issues pop up until then, the code will likely not receive any significant changes, with the exception of a cleaning pass over the license headers, documentation files, etc.

The packages are based on LLVM 3.2 RC and have been built on Ubuntu 10.04 resp. OS X 10.7. The x86_64 packages contain 64 bit compiler binaries, which support generating both 32 and 64 bit executables.

Windows x64 support is progressing steadily, but not yet in a state suitable for general consumption – see https://github.com/ldc-developers/ldc/wiki/Building-and-hacking-LDC-on-Windows-using-MSVC for build instructions.

Thanks to everybody involved in making this happen!

Cool. Are there any plans to continue making pre-compiled releases like this?

Nice work.

I just downloaded the OSX version, but I'm getting a lot of unusual linker errors when trying to compile hello world. Here's the output with ldc -L=-v. I'm running OS X 10.6.8.

Let me know if I should file this as a bug (or if I've just missed something).

We discovered this only pretty recently, but unfortunately this is expected – LLVM relies on operating system support for TLS data, and it was first introduced in OS X 10.7 (dyld support is needed for it to work, so D2 executables generated using a newer OS/toolchain probably won't work on older systems either). Adding a manual TLS implementation to LLVM would be possible as a workaround, but nobody did it so far.

I will be sure to make it clear in the release notes that at least Lion is required.

Yes! Now, that the infrastructure (build bots – thanks Alex! –, packaging scripts, etc.) is in place, and the D2 tests are green by default, our plan is to release new LDC versions coordinated with the DMD release schedule.

To that end – especially because D1 is about to reach end of life –, we might also change the versioning scheme so that the connection to DMD releases is more apparent. This still needs further discussion, though, especially because the current DMD versioning style is not entirely satisfactory.

Cool. I'm hoping to add support for LDC in DVM.

Good job. Compiles and passess all of the unittests of Tango-D2. I'm extra glad that you fixed the installation instructions too... the old ones were horrible.
