When emerging vulkan-loader, lots of errors about unknown type names occur, with no clear solution. 

"emerge -pqv '=media-libs/vulkan-loader-1.1.114::gentoo'" info: 

[ebuild  N    ] media-libs/vulkan-loader-1.1.114  USE="X wayland -layers" ABI_X86="32 (64) (-x32)"

[Comment 1 Nick Sarnie 2020-01-16 23:34:00 UTC]

Please upload /usr/include/vulkan/vulkan_core.h

[Comment 2 27 2020-01-18 05:06:01 UTC]

/usr/include/vulkan/vulkan-core.h does not exist. Maybe something didn't install correctly? According to emerge, I have dev-util/vulkan-headers version 1.1.125 installed.

[Comment 3 Matt Turner 2020-01-18 06:04:59 UTC]

It should be

> /usr/include/vulkan/vulkan_core.h

with an underscore.

Ah! Now I see it; here it is.

[Comment 5 Nick Sarnie 2020-01-21 00:54:55 UTC]

Strange, it's the same as mine. Not sure what could be wrong. Some wild guesses:


1) Try re-emerging vulkan-headers 1.1.125 and try again

2) Try CMAKE_MAKEFILE_GENERATOR="emake" emerge vulkan-headers vulkan-tools

3) Try another gcc version? Shot in the dark

[Comment 6 Nick Sarnie 2020-01-21 00:55:17 UTC]

Sorry, for 2)

CMAKE_MAKEFILE_GENERATOR="emake" emerge vulkan-headers vulkan-loader

>1) Try re-emerging vulkan-headers 1.1.125 and try again

Re-emerging vulkan-headers does not do anything at all. I believe I had tried that multiple times in the past, but just to be sure, I tried again, and it still failed. 

>2) Try CMAKE_MAKEFILE_GENERATOR="emake" emerge vulkan-headers vulkan-tools

For vulkan-tools, it seems that it wants abi_x86_32, which I was advised to disable: 

# required by dev-util/vulkan-tools-1.1.124::gentoo
# required by vulkan-tools (argument)
>=media-libs/vulkan-loader-1.1.125 abi_x86_32

I now have it explicitly enabled instead of explicitly disabled, and the log after trying it again, which still results in failure, is attached to this message.

vulkan build.log with CMAKE_MAKEFILE_GENERATOR="emake" and GCC 8.3.0

Switching from GCC 9.1.0 to GCC 8.3.0 and running the same command (`CMAKE_MAKEFILE_GENERATOR="emake" emerge vulkan-headers vulkan-tools`), I still get the same error, log for this one also attached. I believe I had tried changing the compiler before as well. Has anyone successfully built this package yet? Maybe my system could be compared to it.

[Comment 9 Nick Sarnie 2020-01-23 04:30:37 UTC]

Thanks for trying.

Many people have built this successfully, including myself.

asm_offset.c includes loader.h which includes vulkan.h which includes vulkan_loader.h which has the variables it's complaining about.

I don't know what to try. The header file that defines this variable exists and is correct.

Can you see if /usr/include/vulkan/vulkan.h contains the following lines:

#include "vk_platform.h"
#include "vulkan_core.h"


Thanks,
Sarnex

It does:

#define VULKAN_H_ 1

I'm out of ideas.

[Comment 12 Matt Turner 2020-03-15 21:29:55 UTC]

Fixed in 1.2.xxx?

[Comment 13 27 2020-05-06 22:33:44 UTC]

My large update has finally got to this package, and it works now. 

However, the underlying issue may have also been something that I had forgotten about: I already had a bunch of vulkan files from a custom installation in /usr/local. I just moved a bunch of things in /usr/local to a disabled folder in order to fix another issue, and a lot of things seem to be working a lot better now. Vulkan-loader didn't actually get pulled in until after this change, so maybe the update fixed it rather than /usr/local changes, but if you are reading this and still have this issue even after the update, maybe try cleaning out /usr/local? It can get pretty messy when not managed by a package manager. 

I will mark this as fixed, because whatever fixed it, everything works now.
