Error: expression CONNECTION_INIT = CONNECTION_INIT().ordinal() is not a constant

[Ezneh]

Hello,

While trying to follow the hunt-framework example, I get this error:
Error: expression CONNECTION_INIT = CONNECTION_INIT().ordinal() is not a constant

I am compiling on Windows 10, x86_64 architecture with ldc2 1.21.0 (using dub run).

[Heromyth]

Build the demo for AMQP with dub build --arch=x86_64 --build=debug --compiler=ldc2, and got these error message：

E:\PuTao\Dlang\hunt-amqp-client\examples\SimpleDemo>dub build --arch=x86_64 --build=debug --compiler=ldc2

It's sure that I have enough free memory ( >8G).

The good news is the demo can be built with DMD. So, can you have a try with DMD?

[Heromyth]

By the way, which version is used? I just tested the latest one.

By the way, which version is used? I just tested the latest one.

I tested with dmd (latest version), and now I have some linking errors (libcmt.lib and OLDNAMES.lib missing).

And I tested with ldc2 1.21.0 before.

[Heromyth]

If installing dmd without Visual Studio 2017+, you must install the VC 2010+ runtime.

I have Visual Studio 2019 installed and VC 2010 runtime installed too.

It's so strange. I also failed to build the demo now because of the error: out of memory.
I'll test it again after rebooting my computer later.

Here is my build command:

dub build --arch=x86_64 --build=debug --compiler=dmd

[Heromyth]

It fixed now in commit 5a7f52a. I tested with the latest DMD and LDC2 on Windows.

Run dub upgrade to upgrade all the dependencies to the latest.

[Ezneh]

Alright, after dub upgrade, hunt-proton is compiling with LDC2. However, now the issue comes from hunt-amqp (Error: expression AT_MOST_ONCE = ProtonQoS("AT_MOST_ONCE", 0).ordinal() is not a constant)

[Heromyth]

The hunt-amqp should be upgraded to 1.1.0-beta.3 too. Check this in dub.selections.json, please.

[Ezneh]

It is upgraded to that version as well.

Here is my dub.selections.json

[Heromyth]

It's so sorry. A file was fogot to submit. It's fixed now in commit huntlabs/hunt-amqp@a561292

[Ezneh]

Sorry for the late reply, I was busy this week.

I tried compiling again with both dmd and ldc2 and it seems fine (at least, it's compiling). I will make further tests this weekend and see if it is linking and running properly.

Thanks.
