krita-5.1.0_build.log

The check that's failing means that the size of the `unsigned int` type in your system is *not* 32 bits, which renders those functions unusable.

Can you check what your compiler returns for the size of `unsigned int`?

Alternatively, can you replace the definitions in libs\pigment\compositeops\KoStreamedMath.h as follows, and try building Krita again? Replace "int" and "unsigned int" for "int32_t" and "uint32_t" respectively, in`struct PixelWrapper<quint16, ...>` and `struct PixelWrapper<float, ...>`.

I will at least say that I've also had problems building recent versions of Krita on my Debian sid system. The error I would get at around the 7% mark would be "/usr/bin/ld: cannot find -lxtl: No such file or directory", but it would stop at the same file.

Passing the flag that Timo noted seems to workaround the issue, so it's likely also xsimd related.

Sorry I've no  idea how to do that.

I'm attaching the patch I'm using as krita-5.1.0-xsimd.patch, maybe I did something wrong, with it applied I get the following error:

In regards to what tomtomtomreportingin@gmail.com just posted I want to note that we currently compile our xsimd package with xtl support disabled by passing -DENABLE_XTL_COMPLEX:BOOL=FALSE since we didn't package https://github.com/xtensor-stack/xtl yet.

We don't use xtensor-stack's xtl since we have no need for complex number maths (yet). So that would be best reported to your distribution.

I'm afraid your compiler is definitely reporting the wrong size for 32-bit unsigned integers (not 4 bytes), hence the generic version won't be usable. There's nothing we can do on our end, you'll have to upgrade GCC or build Krita without SIMD acceleration.

For this reason, marking as NOT A BUG.

I haven't come across any issues with other packages and since we're a source-based distribution and compile everything such fundamental issues should become directly obvious.

Also our GCC version is pretty recent:

# gcc -v

After further investigation and finding the actual problem I'd say this is clearly an issue on your side regarding the CMake magic you've implemented doing the wrong thing since if I compile with -march=x86-64 krita builds just fine with vectorization/xsimd enabled, but it fails when trying to build with -march=native on the very same machine with nothing else changed. That shouldn't be the case and I don't consider this an issue with our compiler. Probably you should be able to reproduce this when trying to compile with -march=native as well, not sure what the CMake magic does in regards to different hardware/processor features though and if that may also play a role here.

For reference, working:
CHOST="x86_64-pc-linux-gnu"
x86_64_pc_linux_gnu_CFLAGS="-march=x86-64 -O2 -pipe"
x86_64_pc_linux_gnu_CXXFLAGS="-march=x86-64 -O2 -pipe"

march=native? That's the key to this issue, reopening and assigning to myself.

Assigning.

A possibly relevant merge request was started @ https://invent.kde.org/graphics/krita/-/merge_requests/1552

If you can test build Krita with the MR above, it'd be great.

Appears to work for me with the changes from the MR.

Git commit 9c555836eef341bd6368d6181776838ae7163da0 by L. E. Segovia.

xsimd: fix architecture deduction on amd64 with march=native

Building Krita with march=native breaks a few assumptions existing in
my and Dmitry's code, namely:

- KoOptimizedPixelDataScalerU8ToU16 can't deduce the AVX batch type
  correctly on <= SSE4.1

- KoRgbaInterleavers can't select the correct implementation for AVX,
  because the AVX2 implementation is ifdef'd in instead of the AVX
  version

These assumptions are correct when building Krita with standard compiler
flags, which is why this bug cannot be reproduced in CI or locally out
of the box.

xsimd: fix architecture deduction on amd64 with march=native

Building Krita with march=native breaks a few assumptions existing in
my and Dmitry's code, namely:

- KoOptimizedPixelDataScalerU8ToU16 can't deduce the AVX batch type
  correctly on <= SSE4.1

- KoRgbaInterleavers can't select the correct implementation for AVX,
  because the AVX2 implementation is ifdef'd in instead of the AVX
  version

These assumptions are correct when building Krita with standard compiler
flags, which is why this bug cannot be reproduced in CI or locally out
of the box.
