build fails with current beta dmd (Fedora 21, 64 bit)

[Laeeth]

Any thoughts ?

tango.io.FileScan is deprecated. Please use tango.io.FilePath.toList or tango.io.vfs.* instead.
tango.math.BigInt is deprecated. Please use std.bigint instead.

Any thoughts ?

No, not really. Looks like another regression in DMD. Would nice if you could report it in bugzilla.

[Laeeth]

The current version builds for you on regular dmd? I am pretty sure it does not do so for me, but it was a few weeks ago that I checked. What is your build environment?

[jacob-carlborg]

Yes, it builds with DMD 2.066.1, which is the latest version. I'm using OS X. It should build on Linux as well, since I fairly recently got a pull request jacob-carlborg/mambo#3 to fix that 😉

Make sure you're using v0.1.1 and run dub build --force just to make sure everything is properly rebuilt.

[jacob-carlborg]

I tried DMD 2.067.0-b1 and it doesn't compile. I filed a bug report: https://issues.dlang.org/show_bug.cgi?id=13934

[mihails-strasuns]

It does not make much sense to put in effort into 2.067 beta as it has been abandoned ages ago and will likely be restarted from more recent master again once someone starts taking care of it again.

[Laeeth]

Thanks for coming back.

I downgraded my dmd as Dicebot suggested and am using a different machine now in case problem of local origin. Trouble with clang build (error here, Andersbakken/rtags#204 but the fix didn't work for me) so I used the Fedora 21 distributed clang.

I now have a problem at link stage with tango.

Hmm, I don't know. It seems to be some problem with a symbol in core.stdc.stdarg. BTW, can you use the pre-compiled binaries?

[jacob-carlborg]

@Laeeth BTW, it looks like you didin't use --force when building. It's always a good idea to use that flag when switching between different versions of the compiler. DMD does not have a stable ABI.

[Laeeth]

Hi. I had tried using --force. I am afraid I hadn't seen there were binaries available - my oversight. Works fine for me, and I don't need to build from source now. So I very much appreciate both your building this very useful tool, and your help recently. Laeeth.

[jacob-carlborg]

Good, no worries 😃
