Building codon on Windows 10/11 X64 platform with one step away

[TaiXeflar]

Yes, I'm interested on this project and seen lots of suggest to build on WSL2 or just Linux. But I keep tried various ways(#69) and have some record there.

I prepared 2 ways to build:

First one: Using MSVC(v143) or LLVM based(exaloop/llvm-project Clang/LLVM) build on Visual Studio 2022. I'm still keep trying these builds.

• pwsh (PowerShell 7, VS2022 environment)

 cd ~/Desktop;                                                                      # powershell recognize ~ path(unix-like) to $env:USERPROFILE
 git clone https://github.com/exaloop/llvm-project.git --depth=1      
 mkdir llvm-project/build; cd llvm-project/build                                    # powershell mkdir == shell "mkdir -p"
 
 cmake ../llvm -G Ninja                                                 \           # Ninja Generator
        -DCMAKE_BUILD_TYPE=MinSizeRel                                   \           # This option is due to my small 2TB SSD
        -DCMAKE_C_COMPILER=cl.exe                                       \           # MSVC v143 14.40.33807, cl= msvc compiler driver
        -DCMAKE_CXX_COMPILER=cl.exe                                     \           # MSVC v143 14.40.33807, cl= msvc compiler driver
        -DCMAKE_ASM_MASM_COMPILER=ml64.exe                              \           # MSVC Macro Assembler compiler
        -DCMAKE_INSTALL_PREFIX="C:/Developer/Codon/llvm"                \                       
        -DLLVM_TARGETS_TO_BUILD="host;NVPTX"                            \
        -DLLVM_ENABLE_PROJECTS="clang;lld"                              

 cmake --build . --target install       

 cd ~/Desktop; 
 git clone https://github.com/exaloop/codon.git --depth=1 --branch=windows
 mkdir codon/build; cd codon/build
 
 cmake .. -G Ninja
          -DCMAKE_BUILD_TYPE=MinSizeRel
          -DCMAKE_C_COMPILER=cl
          -DCMAKE_CXX_COMPILER=cl
          -DCMAKE_ASM_MASM_COMPILER=ml64
          -DCMAKE_PREFIX_PATH="C:/Developer/Codon/llvm"
          -DCMAKE_INSTALL_PREFIX="C:/Developer/Codon"
          -DCODON_GPU=ON

    # Remind in VS2022 env no target C/CXX compiler will auto select MSVC
    #

The build record see #69.

Second way: I rebuild llvm/clang and codon again, but Using "Strawberry Perl" with toolkit have GCC compiler:

 cd ~/Desktop;                                                                      # powershell recognize ~ path(unix-like) to $env:USERPROFILE
 git clone https://github.com/exaloop/llvm-project.git --depth=1      
 mkdir llvm-project/build; cd llvm-project/build                                    # powershell mkdir == shell "mkdir -p"
 
 cmake ../llvm -G Ninja                                                 \           # Ninja Generator
        -DCMAKE_BUILD_TYPE=MinSizeRel                                   \           # This option is due to my small 2TB SSD, Again
        -DCMAKE_C_COMPILER=gcc.exe                                      \           # MSVC v143 14.40.33807, cl= msvc compiler driver
        -DCMAKE_CXX_COMPILER=g++.exe                                    \           # MSVC v143 14.40.33807, cl= msvc compiler driver
        -DCMAKE_INSTALL_PREFIX="C:/Developer/Codon/llvm-gcc"            \                       
        -DLLVM_TARGETS_TO_BUILD="host;NVPTX"                            \
        -DLLVM_ENABLE_PROJECTS="clang;lld"                              

 cmake --build . --target install       

 cd ~/Desktop; 
 mkdir codon/build-gcc; cd codon/build-gcc
 
 cmake .. -G Ninja
          -DCMAKE_BUILD_TYPE=MinSizeRel
          -DCMAKE_C_COMPILER=gcc.exe
          -DCMAKE_CXX_COMPILER=g++.exe
          -DCMAKE_ASM_MASM_COMPILER=ml64.exe
          -DCMAKE_PREFIX_PATH="C:/Developer/Codon/llvm-gcc"
          -DCMAKE_INSTALL_PREFIX="C:/Developer/Codon"
          -DCODON_GPU=ON

 cmake --build .
    # By passing "CMAKE_ASM_MASM_COMPILER" to set Assembler compiler

And the second way have almost complete build(), but stop at ld.exe:

 x86_64-w64-mingw32/bin/ld.exe: error: export ordinal too large: 71633
 collect2.exe: error: ld returned 1 exit status

This is quite happy and f**k to me just a little bit objects to finish it... going play Genshin Impact for a little break.
Hope these results helps.

Considering the seconds case error, that is the windows limitation. This problem is actually described here: error-export-ordinal-too-large-104116 and the proposition there is to try -fvisibility=hidden in GCC and CLANG to hide some exported functions. Can you try to build it that way?

[TaiXeflar]

Sorry for a long time reply. I actually tried this way: The GCC toolchain compile is pretty normal with a fast speed by ninja until linking, it will stucks at very long time, with a high memory usage, and finally stoped linking by printing unknown external linking symbol(10k lines and more). The LLVM toolchain compiles also well, but with a build of lld or msvc linker also quickly stop with link problems(unknown symbol).
