where to find libvulkan 32bit

Hello guys (and gals, if any) after a few hours of trial and error (and new stuff to learn) I've managed to have a fully working vulkan enviroment for my 14.2 64bit (multilib)

In the end the only necessary thing was to install vulkansdk fron sbo (which also installs the /usr/lib64/libvulkan thing)

Now, while building wine 3.13 with wow64 and vulkan support, I've came across an error, saying that I miss 32bit libvulkan and 32bit moltenvk... which is true, in /usr/lib there's no trace of them...

So, the question is: where do I find the 32bit libraries?
I've looked for them in Lunar's site, but no luck, it seems that lunar's vulkansdk support ONLY 64bit...

Maybe I'm missing something obvius, but I can't really find the 32bit version anywhere (exept for some precompiled RPM on random websites... which I would prefer to avoid)

Any clue?

Thanks in advance!

It would need to be built for source where the SBo script is a binary repackaging, see vulkan from the main tree for current. I'm not sure what the issue with building it for 14.2 is?

You need to read the multilib instructions to build 32bit packages.

https://docs.slackware.com/slackware:multilib

see the section "Compiling 32-bit programs" , to build packages in 32bit

Make a 32-bit 14.2 VM.

Use the -current SlackBuild to build the Vulkan SDK in the 32-bit 14.2 VM.

LunarG provides 64-bit SDK binary packages but not 32-bit SDK packages. However, they also provide the sources used to build those packages.

Ok, I will try building it then, didn't noticed that sbo's version was a binary repackage.
compiling should solve the problem.
Thank you!

Thanks for the pointer!

Thanks, if I'll not manage building with multilib, I'll try that!

Ok, I've tried to compile the Slackbuild found here: https://mirrors.slackware.com/slackw.../x/vulkan-sdk/

Of course, before trying I've done a

Now, I've really no clue on what to do....
some info:

Code:

uname -a

Linux spikeship 4.14.59-spikeship #1 SMP PREEMPT Sat Jul 28 16:48:27 CEST 2018 x86_64 AMD Athlon(tm) II X3 440 Processor AuthenticAMD GNU/Linux



gcc:

gcc-5.5.0_multilib-x86_64-1alien

gcc-g++-5.5.0_multilib-x86_64-1alien



cmake:

cmake-3.5.2-x86_64-1

Note that I've successfully compiled a whole lot of other programs in 32bit, although only with the help of a "sboinstall -p" command
Any clue on what to do now?

I have two suggestions, first use an english locale, it makes it easier to read your logs. Second try building it for 64-bit first, it could make debugging it easier with the reduced complexity.

Hello again guys, no luck compiling 64bit Vulkan:

Any idea on what I miss?

Let's suppose that my slackware 14.2, while updated, it's still plain vanilla 64bit, what packages would I miss to compile that?

Could it have anything to do with lambda? however can't find anything in SBo...

Its a general build issue, not a dependency issue. I think its an old glibc bug, but I'm not sure the best way to solve it short of upgrading to current. You can check out this similar issue report for some other ideas.

Well, thank you and thanks to all the ones who replied this thread for the kind help.

I'll see what to do next,

Works for me on 64bit 14.2 after adding the line:

Code:

sed -i -e '/#include/i#include <cmath>\n' layers/parameter_validation_utils.cpp

in -current's SlackBuild just before the commented out line: # chown -R root:root .

WOW thank you! It worked ideed!

But i've found out it's not enough to build the 32bit version on multilib.

After a few researches I've found the solution to that too, I'll leave it here for whoever will need that in the future:

Code:

. /etc/profile.d/32dev.sh

ARCH=i586 ASFLAGS=--32 ./vulkan-sdk.SlackBuild

Without the ASFLAG snippet it was failing complaining to asm stuff.
I'm nowhere near expert on multilib things, but shouldn't asm flags be part of the 32dev.sh profile, just as the m32 cflags and cxxflags?

Anyway, thanks to all of you guys, problem SOLVED!
