OpenBLAS build for Win x86 with cmake + VC fails when -DDYNAMIC_ARCH=ON

[realgarik]

Hi,

I'm trying to build openBLAS for Windows x86 platform as it is described in build page:
CMake and Visual Studio
To build OpenBLAS for the 32-bit architecture, you'll need to use the builtin Visual Studio compilers.

Here is the cmake command that I'm running on my "Haswell" host machine. Afterwards build with VS17 completes successfully:
cmake -G "Visual Studio 15 2017" -A Win32 -DBUILD_WITHOUT_LAPACK=no -DNOFORTRAN=0 -DCMAKE_BUILD_TYPE=Release

but once I'm adding the DYNAMIC_ARCH feature enabling like this:
cmake -G "Visual Studio 15 2017" -A Win32 -DBUILD_WITHOUT_LAPACK=no -DNOFORTRAN=0 -DDYNAMIC_ARCH=ON -DCMAKE_BUILD_TYPE=Release
the build fails with some errors without generating the output library.
Note: that the same feature set mentioned above is working for x64 architecture using "1. Native (MSVC) ABI" build option.

Is it a known issue, or am I missed something?

You certainly missed to mention what the "some error" messages are...

[realgarik]

Definitely I've missed, because I'm facing some strange behavior so I don't know what to attach

Now I've received the full error list:

[martin-frbg]

That seems to be the same error as in #2746, somehow the preprocessor does not get run or does not insert the relevant constants e.g. for the size of "subbuffer" into the source files before compiling. (In #2746 I had assumed it was a problem with the build system not working with the Intel compiler, but perhaps this is/was actually an x86 build problem as well.) Offhand I do not see why x86 should behave differently, I will see if I can reproduce this.

[isuruf]

DYNAMIC_ARCH is not supported when building with Visual Studio compilers since the compiler doesn't understand the assembly syntax used in OpenBLAS. You can only build the TARGET=generic kernel.

[realgarik]

Thanks for support!
So do I need just add TARGET=generic to my cmake command and remove DYNAMIC_ARCH=on?

Also is there any other way to build x86 to use the static lib with VS?

[isuruf]

yes

[martin-frbg]

DYNAMIC_ARCH is not supported when building with Visual Studio compilers

Of course... where's my head today ?

[realgarik]

I didn't know this, maybe it will be nice to highlight that line in build page for x86.
I did builds with minGW and conda with enabled DYNAMIC_ARCH, so I thought it will be applicable with x86 build as well))

Ok guys, thank you very much for your support, I was able to successfully build the lib by removing DYNAMIC_ARC and adding -DTARGET=generic to my build command.

[realgarik]

@martin-frbg, @isuruf ,

Is there any way to build x86 like it was done for x64?

1. Native (MSVC) ABI with Miniconda3 ninja, LLVM etc.

As with VS build version I see significant performance loss, about 5x times worse compared to #1 build for x64

[isuruf]

You can, but you'll have to disable LAPACK and LAPACKE. Are you using BLAS and CBLAS only?

[realgarik]

Yes, I'm using BLAS only

for x64 I did with the following configuration

cmake .. -G "Ninja" -DCMAKE_CXX_COMPILER=clang-cl -DCMAKE_C_COMPILER=clang-cl -DCMAKE_Fortran_COMPILER=flang -DBUILD_WITHOUT_LAPACK=no -DNOFORTRAN=0 -DDYNAMIC_ARCH=ON -DCMAKE_BUILD_TYPE=Release

and it works well, but the same I've tried by setting VS tools for x86 and providing -A Win32 to cmake but it failed to configure

[realgarik]

The following error I received for x86:

cmake .. -G "Ninja" -A Win32 -DCMAKE_CXX_COMPILER=clang-cl -DCMAKE_C_COMPILER=clang-cl -DCMAKE_Fortran_COMPILER=flang -DBUILD_WITHOUT_LAPACK=no -DNOFORTRAN=0 -DDYNAMIC_ARCH=ON -DCMAKE_BUILD_TYPE=Release

Win32

was specified.

CMake Error: CMAKE_ASM_COMPILER not set, after EnableLanguage
-- Configuring incomplete, errors occurred!

[isuruf]

The same build command line should work. (You don't need -A Win32) Did you activate the x86 tools in a new cmd?

[realgarik]

ok thanks, I will try one more time without -A Win32 and making sure to activate x86.

[realgarik]

Can you do the following,

set CC=clang-cl
set CFLAGS=-m32
set CXX=clang-cl
set CXXFLAGS=-m32

clean the build directory and start again?

[realgarik]

I've cleaned the build directory, set above mentioned variables and run the same command, here is the result:

You need to do the following to disable fortran

cmake .. -G "Ninja" -DCMAKE_CXX_COMPILER=clang-cl -DCMAKE_C_COMPILER=clang-cl -DBUILD_WITHOUT_LAPACK=yes -DNOFORTRAN=1 -DDYNAMIC_ARCH=ON

[martin-frbg]

@isuruf seems the problem is with linking the getarch tool (which wants to be built for the x64 compile host as it needs to run as part of the build). I do not recall this being a problem but maybe something got broken fairly recently (or nobody actually tried this quasi-crosscompile on Win10) ?

[realgarik]

If this build is broken recently, then maybe reasonable to try with an older version instead of using the latest one?

[isuruf]

@realgarik, can you try downloading clang for 32-bit from https://llvm.org and add it to the front of the PATH?

[realgarik]

Let me download it, if I understand it correctly, I need to build clang for windows...

[isuruf]

Here's a pre-built binary, https://github.com/llvm/llvm-project/releases/download/llvmorg-10.0.0/LLVM-10.0.0-win32.exe

[isuruf]

@martin-frbg, do you know if CMAKE_CXX_FLAGS is passed when compiling getarch?

[martin-frbg]

@isuruf it is not explicitly passed at least - cmake/prebuild.cmake from line 500 would be the place to check. (I do not think anything with a CMAKE_CXX_ prefix is used anywhere in the build ?)

[isuruf]

Sorry, I meant CMAKE_C_FLAGS. I'll have a look.

[martin-frbg]

Hmm. I see CMAKE_C_FLAGS_DEBUG conditionally appended to GETARCH_FLAGS in system.cmake, but no explicit passing or adding of CMAKE_C_FLAGS in either file.

[realgarik]

@isuruf today I've built the clang for Win32 arch. Did the same variable initialization that you provided before for CC and CXX variables to set to my newly built clang-cl.exe and here is the result for cmake build:

[isuruf]

@realgarik, can you send the full output after a clean build? I suspect that the correct clang-cl was not picked up.

[realgarik]

@isuruf ,

Actually by correctly setting CC, CXX flags to refer to my newly built clang-cl.exe

set CC="C:/home/llvm-project-master/build/Release/bin/clang-cl.exe"
set CFLAGS=-m32
set CXX="C:/home/llvm-project-master/build/Release/bin/clang-cl.exe"
set CXXFLAGS=-m32

and providing the same .exe to cmake command line:

cmake .. -G "Ninja" -DCMAKE_CXX_COMPILER="C:/home/llvm-project-master/build/Release/bin/clang-cl.exe" -DCMAKE_C_COMPILER="C:/home/llvm-project-master/build/Release/bin/clang-cl.exe" -DBUILD_WITHOUT_LAPACK=yes -DNOFORTRAN=1 -DDYNAMIC_ARCH=ON

I was able to complete build, but now I am receiving the linker errors:

The list is long for dynamic arch, so I will mention just module names which are failing:
setparam_KATMAI.c.obj
setparam_COPPERMINE.c.obj
setparam_NORTHWOOD.c.obj
setparam_PRESCOTT.c.obj
setparam_BANIAS.c.obj
setparam_NEHALEM.c.obj
setparam_CORE2.c.obj
setparam_ATHLON.c.obj
setparam_BARCELONA.c.obj

@isuruf , @martin-frbg ,

do you have any clue for these link issues?
have you ever faced such an issue?

[martin-frbg]

Sorry; I have no idea what is happening here. I trust you started from a clean build directory every time you changed cmake options (?) Perhaps a complete build log would help (and perhaps you could add CMAKE_VERBOSE_MAKEFILE=ON to your
cmake options for additional information, though it will increase the size of the log) ?

[LYP951018]

Maybe unrelated, but MSVC does not support VLA and AT&T assembly which are required by DYNAMIC_ARCH.

[martin-frbg]

Maybe unrelated, but MSVC does not support VLA and AT&T assembly which are required by DYNAMIC_ARCH.

Yes, this was clarified in #2826 (comment) , then TARGET=generic was used instead with MSVC and the discussion moved on to building with LLVM (clang-cl) for better performance - which worked for x64 but failed for 32bit. (Maybe the "wrong" linker got called, or 64bit object files got picked up from an earlier build attempt, but at that point it seems everybody ran out of time or energy)

[realgarik]

Sorry guys I didn't have time to dig into the issue so finally it was decided to drop the x86.
Thank you very much for your support!
