Does the Konan Gradle plugin have a way to setup environment variables? Trying to run the weather program (was successfully compiled and linked) through Gradle, but an error appears:

> Task :runWeather FAILED
/home/napperley/repos/openfaas-weather-sample/build/konan/bin/linux_x64/weather.kexe: error while loading shared libraries: libcjson.so.1: cannot open shared object file: No such file or directory

The same as with Gradle Groovy You can use environment variables

for run task would be probably better to modify run task itself and pass variables there

Tried that via

tasks.withType<JavaExec>{ doFirst { //... } }

but it didn't have any effect. 🙁

Do you want use libcjson as shared library? Maybe easier just to use it as static library? especially for your case

I don’t think that konan

run

task is inherited from JavaExec

huh, looks that you cannot pass environment variables directly to run, https://github.com/JetBrains/kotlin-native/blob/60fff469304b4d06e87f89d4a79dd1c1b22025ad/tools/kotlin-native-gradle-plugin/src/main/kotlin/org/jetbrains/kotlin/gradle/plugin/KonanPlugin.kt#L303-L319

but probably can do that directly to gradle, something like: MY_ENV_VAR=something ./gradlew run

Probably should also look into using libcurl as a static library too, unless Kotlin Native has a way of statically linking a KLib into a Kotlin Native program (binary).

Had a look at what libcurl needs for static linking by running the following:

curl-config --static-libs
/usr/lib/x86_64-linux-gnu/libcurl.a -Wl,-Bsymbolic-functions -Wl,-z,relro -Wl,--as-needed -lidn -lrtmp -lssl -lcrypto -lssl -lcrypto -Wl,-Bsymbolic-functions -Wl,-z,relro -lgssapi_krb5 -lkrb5 -lk5crypto -lcom_err -llber -llber -lldap -lz

Tried appending everything after "libcurl.a" to compilerOpts.linux in the definition file, however it doesn't work with libcurl. Tons of "undefined reference" errors are appearing ☹️.
