Build errors in Windows Visual Studio 2015 - expression must have a constant value about opus

[rillian]

It's difficult to say without seeing your config and the exact error message. Opus as several allocator configurations.

If it's any help, 1.2.1 does build in automation under Visual Studio 2015.

[SMUsamaShah]

Well, these are the steps.

1. I downloaded opus 1.2.1 source. Opened opus.sln from opus-1.2.1\win32\VS2015\.
2. Select Release and Win32 configuration, (other configurations give the same result)
3. Select the project opus from solution explorer panel, right click and build.
4. I get following output :)

It looks like there's a problem with your config.h and somehow VS is trying to use the C99 VLAs rather than alloca().

[SMUsamaShah]

@jmvalin Anything I should try as a workaround?

[evpobr]

Opus v1.2.1 with VS2017 (with VS2015 platform toolset) - no error. Actually, even no warnings.

Opus v1.2.1 from GiHub also works.

[evpobr]

The only way to get the same errors is to add manually VAR_ARRAYS to definitions list.

[jmvalin]

Doesn't look like it's a bug. Closing for now.

Maybe you should decompress a clean source code separately, and then compile it in win32/VS2015 at windows.
When I use automake compiled at unix in the root source directory and then went to win32/VS2015 at windows to compile, the problem you mentioned also appeared. So I create another clean copy of the source code and compiled it at windows again, and there was no problem.
[Opus v1.3.1] with VS2022 (with VS2017 platform toolset) - no error. Actually, even no warnings.
