digitalmars.D.learn - Which Docker to use?

Hi,

I need to build some static binaries with LDC. I also need to 
execute builds on both platform 32-bit and 64-bit.


 From Docker Hub there are two image groups:

* language/ldc (last update 5 months ago)
* dlang2/ldc-ubuntu (updated recently)


Which one do you suggest?

Thanks a lot.

To be honest, you don't need docker for this. You can just 
download LDC in a self-contained folder and use it as is.

That's what I do on Linux.

I need to use docker to build static linked Linux executables. My 
reason is specific, may be different than the OP's. I'm using 
Travis-CI to build executables. Travis-CI uses Ubuntu 14.04, but 
static linking fails on 14.04. The standard C library from Ubuntu 
16.04 or later is needed. There may be other/better ways to do 
this, I don't know.

Yes I'm also using Travis-CI and that's why I need some Docker 
support.

I'm using dlanguage/ldc. The reason for that choice was because 
it was what was available when I put the travis build together. 
As you mentioned, it hasn't been updated in a while. I'm still 
producing this build with an older ldc version, but when I move 
to a more current version I'll have to switch to a different 
docker image.

My travis config is here: 
https://github.com/eBay/tsv-utils/blob/master/.travis.yml. Look 
for the sections referencing the DOCKERSPECIAL environment 
variable.

That's interesting. I've built static binaries for DStep using LDC on 
Travis CI without any problems.

My comment painted too broad a brush. I had forgotten how 
specific the issue I saw was. Apologies for the confusion.

The issue that caused me to go to Ubuntu 16.04 had to do with 
uncaught exceptions when using LTO with the gold linker and LDC 
1.5. Problem occurred with 14.04, but not 16.04. I should go back 
and retest on Ubuntu 14.04 with a more recent LDC, it may well 
have been corrected. The issue thread is here: 
https://github.com/ldc-developers/ldc/issues/2390.

Ah, that might be the reason. I am not using LTO. You might want to try 
a newer version of LDC as well since 1.5 is quite old now.

I switched to LDC 1.12.0. The problem remains with LTO and static 
builds on Ubuntu 14.04. Ubuntu 16.04 is required, at least with 
LTO of druntime/phobos. The good news on this front is that the 
regularly updated dlang2 docker images work fine with LTO on 
druntime/phobos (using the LTO build support available in LDC 
1.9.0). Examples of travis-ci setups for both dlanguage and 
dlang2 docker images are available on the tsv-utils travis 
config: 
https://github.com/eBay/tsv-utils/blob/master/.travis.yml. Look 
for the DOCKERSPECIAL environment variables.
