Kotlin-native: CLion Kotlin Native not support Windows?

[lzl471954654]

I use windows 10.
When I download and configure Kotlin Native on CLion.
I created a default Hello World project and want to try complied and run.
But there is a CMake error

CMake Error at KotlinCMakeModule/CMakeKotlinInformation.cmake:128 (message):
Unsupported host target
Call Stack (most recent call first):
KotlinCMakeModule/CMakeKotlinInformation.cmake:170 (prepare_konanc_args)
CMakeLists.txt:7 (konanc_executable)
-- Configuring incomplete, errors occurred!
See also "D:/KotlinNative/CSVParser/cmake-build-debug/CMakeFiles/CMakeOutput.log".
[Failed to reload]

Then i saw the file named CMakeKotlinInformation.cmake

    if (NOT KONANC_TARGET)
        if (APPLE)
            set(KONANC_TARGET macbook)
        elseif (UNIX)
            set(KONANC_TARGET linux)
        else ()
            message(FATAL_ERROR "Unsupported host target")
        endif ()
    endif ()

@msink Thank you very much. ^_^

To make it work, i did:

set(KONANC_TARGET mingw)

inside the else() section.

It compiled, then i added an extension, but can't remember where.

[msink]

I tried something like that - it's lost after any reconfiguration, so hardly usable.

@hpcorona
I tried to change it

set(KONANC_TARGET mingw)

but there still a CMake Error

KONANC_TARGETmingw
CMake Error at KotlinCMakeModule/CMakeKotlinInformation.cmake:174 (if):
if given arguments:
"STREQUAL" "wasm32"
Unknown arguments specified

in the CMakeKotlinInformation.cmake

    if(${KONANC_TARGET} STREQUAL "wasm32")
        set(EXECUTABLE_EXTENSION "wasm")
    elseif (${KONANC_TARGET} STREQUAL "android_arm32")
        set(EXECUTABLE_EXTENSION "so")
    elseif (${KONANC_TARGET} STREQUAL "android_arm64")
        set(EXECUTABLE_EXTENSION "so")
    else()
        set(EXECUTABLE_EXTENSION "kexe")
    endif()

Using latest Clion and Kotlin/Native plugin installed, you need to make the following changes:

1. Add the followings after 126 line in the file KotlinCMakeModule/CMakeKotlinInformation.cmake:

        elseif (WIN32)
            set(KONANC_TARGET mingw)

1. Add to the end of 85 line in the cmake-build-debug/CMakeFiles/HelloWorld.kexe.dir/build.make to the following

.exe

1. Put on path a win32 equivalent of rm unix command line utility. I found it within already installed cmder. Be aware, you have to put it separately from other utilites, because of warning of the Clion cmake told it can't properly work with sh on path.

After the foregoing changes, I had got Clion successfully building "hello world" project.

[Draciel]

@wapxmas How I can change path? I changed RM path in cmake-build-debug/CMakeFiles/HelloWorld.compile.dir/build.make to Cmdr.exe but still this same issue with RM remains.

[wapxmas]

@Draciel Copy from cmder\vendor\msysgit\bin the following files: rm.exe, msys-1.0.dll to any other directory. After that put the foregoing directory on the path.

[neonailol]

@wapxmas No need to change make files, just remove ${EXECUTABLE_EXTENSION} part from lines 220-223, so it looks like

add_executable(${KONANC_NAME} ${KONANC_SOURCES})
add_dependencies(${KONANC_NAME} ${KONANC_NAME}.compile)
set_target_properties(${KONANC_NAME} PROPERTIES LINKER_LANGUAGE Kotlin)
add_custom_command(TARGET ${KONANC_NAME}

and the full diff of changes mentioned in this thread is

@neonailol Thank you, didn't dig as deep as you did.

@neonailol CMake does not know of any WINDOWS. You should use WIN32
https://cmake.org/cmake/help/latest/variable/WIN32.html

Still it will look something like:

"C:\Program Files\JetBrains\CLion 2017.2.2\bin\cmake\bin\cmake.exe" --build E:\w\w2\kn\hw\cmake-build-debug --target HelloWorld -- -j 4

Hi, I'm trying to setup the plugin with the last release of CLion and I can't manage to setup a win32 equivalent of rm unix command line utility (like @wapxmas suggest).
I downloaded cmder, copied rm.exe with the necessary .dll files in a different directory and then changed RM path in cmake-build-debug/CMakeFiles/HelloWorld.compile.dir/build.make to that directory, but I still can't build the HelloWorld project. What I'm supposed to do? I don't understand what I'm doing wrong.
I've also tried to link the directory in the PATH of system environment variables of Windows, but still have the problem.

If anyone needs a working reference, I have created a repo for that: https://github.com/Mordag/helloworld

If you get this error, just ignore it and rebuild:

'rm' is not recognized as an internal or external command,
operable program or batch file.
NMAKE : fatal error U1077: 'rm' : return code '0x1'
Stop.

@ttldtor the memory error

can be fixed by installing the 64-bit version of the JRE from here:
