Hi everyone!

On behalf of the LDC team I am proud to announce the LDC 0.16.0 alpha3 release!
It is based on the 2.067.1 front-end and LLVM 3.1-3.7 (OS X: no support for 3.3).

This alpha version fixes some issues and adds new features. The LDC team already considers this the best LDC release of all times!
Most important changes are:

- Frontend is now at 2.067.1
- LLVM 3.7 is supported
- DMD-style coverage analysis is added
- ABI changes which fixes a lot of bugs in the Win64 compiler

Be sure to read the change log at the GitHub release page which also has the package download links:
https://github.com/ldc-developers/ldc/releases/tag/v0.16.0-alpha3

Note: This release has alpha quality. There are known and unknown bugs left. Please test it with your projects!

Due to a library build problem with Phobos there is currently no MinGW32 version. !!!Volunteer help wanted!!!

Regarding the binaries:
The Linux binaries are built on Ubuntu 12.04 LTS with gcc 4.8.x and LLVM 3.6.2. They work on Ubuntu 12.04 LTS (or later) without installing additional software.

The OS X binaries are now built on OS X 10.10. It is currently unknown if this causes backwards compatibility issues.

The Win64 MSVC version is still considered alpha quality. It is built with VS2013 using LLVM 3.7 in release mode. The distribution now contains a precompiled libcurl 7.40.0 from http://d.darktech.org/libcurl.html.
Attention: There is a regression in LDC or a bug in LLVM which currently requires the use of linker flag -L/FORCE:MULTIPLE (issue #988). This issue is already partially solved.
You find the build script here: https://github.com/ldc-developers/ldc-scripts/blob/master/ldc2-win64/RELEASE.proj

Please be sure to report any bugs at https://github.com/ldc-developers/ldc/issues, and feel free to drop by at the digitalmars.D.ldc forums (http://forum.dlang.org/group/digitalmars.D.ldc) for any questions or comments.

Thanks to everybody involved in making this happen!

Regards,
Kai

Is this version supposed to contain the fix for this bug?
https://github.com/ldc-developers/ldc/issues/1061

Because I still get this error:
Error: failed to create path to file: .dub/obj/../../.dub/packages/memutils-0.3.5/.dub/build/secure-unittest-linux.posix-x86_64-ldc_0-38ACFEB5A4C0EFEDC50803AF380B9A85/libmemutils.a

The workaround commit https://github.com/ldc-developers/ldc/commit/2a206453c0a60d31ff37a2573127ae22e9efd8f3 seems to be part of the release tag at least.

Could you post this (and the full ldc2 command line) to the GitHub issue tracker, please?

You can use dub --combined to work around this

I'm having a problem building my project with this version using dub.

Using `dub build --compiler=path-to-ldc/ldc2`:

Error executing command build:
Source file does not exist.

Using `dub build --compiler=path-to-ldc/ldmd2`:

Error: Output file 'package.o' for module 'aw.g2nc' collides with
previous module 'aw.dp'. See the -oq option
FAIL ../lib/.dub/build/library-debug-linux.posix-x86_64-
ldc_2067-6CBF3AB0F6005CC5D5CF579F69F56135/ awmms-lib staticLibrary
Error executing command build:
/home/administrator/apps/ldc2-0.16.0-alpha3-linux-x86_64/bin/ldmd2 failed
with exit code 1.

I can't create a minimal test case right now. But, at least for ldmd2, the problem seems that I have two package.d files and their output object files are colliding.

I will try to create a minimal test case in the next few days if the problem is still unclear by then.

As a work-around for the first bug you can use --combined

The second bug is probably https://github.com/D-Programming-Language/dub/issues/634
Make some noise here.

The workaround works perfectly, thanks.

No regressions in my software. After reading the Changelog, I wonder how I ever managed without this compiler, best release ever!

Thanks,

This is a problem with my "Road Warrior" setup. I need to update the build scripts to check for this error. I am already preparing the next alpha release to fix this.
