Building native - Default native-compiler executable 'cl.exe' not found via environment variable PATH

[Mark Jayson Gonzaga]

Hi Team,

I have been trying to build our quarkus project natively following this article.

https://quarkus.io/guides/building-native-image

I'm running Windows 10 and upon building I got the below error.

Error: Default native-compiler executable 'cl.exe' not found via environment variable PATH
Error: To prevent native-toolchain checking provide command-line option -H:-CheckToolchain
com.oracle.svm.core.util.UserError$UserException: Default native-compiler executable 'cl.exe' not found via environment variable PATH
To prevent native-toolchain checking provide command-line option -H:-CheckToolchain

I have graalvm and the Microsoft Native Tools in my machine but still getting the above error.

As advised from the article. I created this bat file 

cmd /c 'call "C:\Program Files (x86)\Microsoft Visual Studio\2017\BuildTools\VC\Auxiliary\Build\vcvars64.bat" && mvn package -Pnative'

But still getting the same result. I tried looking for the above error from the internet but wasn't able to find a solution for this. Wondering if anyone got the same exception or is it just me

Thanks for the help.

Do you have visual studio installed?

Hello,

On a windows CI, I had to install "Developer Command Prompt for Microsoft Visual C++” to get the GraalVM compiler working.

Hello,

GitHub workflow Windows systems have Visual studio installed IIRC, so one "just" needs to do some trickery with env vars [1].

If you have your own box, all it takes is to use Choco

to install VS and to setup PATH:

(my script, Powershell dummy, use with caution)

https://gist.github.com/Karm/56b5d7286482e45fc3bbb54aa00fbfaf

The you can run as simply as:

call vcvars64
set "GRAALVM_HOME=....."
set "JAVA_HOME=%GRAALVM_HOME%"
set "PATH=%JAVA_HOME%\\bin;%PATH%"

mvnw....

HTH

Cheers

K.
