Though I have http_proxy env variable set up properly

[olonho]

have you tried solution in https://github.com/JetBrains/kotlin-native/issues/1446?

[anidotnet]

Nope

[anidotnet]

I am using Clion and I have provided the details as follows:

[anidotnet]

Sorry could not upload screenshot here so I uploaded in the channel

[anidotnet]

Even I tried with below settinngs in cmake file

[anidotnet]

set(ADDITIONAL_KONANC_FLAGS "-Dhttp.proxyHost=******** -Dhttp.proxyPort=*******")
set(CMAKE_Kotlin_FLAGS "-Dhttp.proxyHost=********* -Dhttp.proxyPort=******")

[anidotnet]

but no result

[olonho]

could you please try konanc with -D options as suggested in the bug and let us know the result. Could you run other networked Java programs?

[anidotnet]

Yes I can run other java program using -Dhttp.proxyHost

[anidotnet]

I didnot get he konanc part. I am running from CLion using cmake. Where do I set these?

[olonho]

please download Kotlin/Native redistributable https://github.com/JetBrains/kotlin-native/releases/tag/v0.6.2 for your platform and run command line compiler called konanc. It will download all needed toolchains.

[anidotnet]

$ ~/.konan/kotlin-native-linux-0.6.2/bin/konanc      
error: you have not specified any compilation arguments. No output has been produced.

[olonho]

build some sample from samples folder

[anidotnet]

First I set export COMPILER_ARGS_linux='-Dhttp.proxyHost=**************** -Dhttp.proxyPort=********' and then run build.sh. Still same error. After that I started gradle build with proxy args let see.

[olonho]

nope, try ./gradlew -D...

[anidotnet]

Just now tried with ./gradlew -Dhttp.proxyHost=*********** -Dhttp.proxyPort=****** build

[anidotnet]

but got this error

> Task :csvparser:compileKonanCsvParserLinux 
Downloading native dependencies (LLVM, sysroot etc). This is a one-time action performed only on the first run of the compiler.

Waiting 3.0 sec and trying again (attempt: 2/10).

[olonho]

hmm, are you sure this is correct proxy config? could you check that it matches your browser config?

[anidotnet]

Yes positively. The same gradle command build my java projects just fine

[olonho]

also try -Dhttps.proxyHost= -Dhttps.proxyPort=

[anidotnet]

Tried this too

[anidotnet]

None of these works

[anidotnet]

So any solution for this? Oh and this gradle setting just successfully downloaded gradle 4. 5 dist while building samples.

[olonho]

hard to tell, generally -D solution is known to work for cases we aware of. You could try to debug the download code, which is at https://github.com/JetBrains/kotlin-native/blob/master/shared/src/main/kotlin/org/jetbrains/kotlin/konan/util/DependencyDownloader.kt

[olonho]

oh, and try ./gradlew -stop

[anidotnet]

@olonho I tried many more methods. Only working solution is, I modified run_konan script as below

java_opts=(-ea \
            -Djava.net.useSystemProxies=true \
            -Xmx3G \
            "-Djava.library.path=${NATIVE_LIB}" \
            "-Dkonan.home=${KONAN_HOME}" \
           -Dfile.encoding=UTF-8)

[olonho]

cool, then it means proxy servers you pass originally were not functional and so relying on system-wide proxy config worked. Likely you could pass same argument via -D switch.

[anidotnet]

No that did not work. Reading the shell scripts for linux I understand it is not propagating those args to the run_konan that's why it was not working. In place of java.net.useSystemProxies if I pass http.proxyHost and http.proxyPort in run_konan, that was also working. I choose the java.net.useSystemProxies as I don't have to pass host, port again. Can you please verify if those -D args are being passed from gradle script to run_konan properly?

We think we have found the root cause of issue and are working on the resolution. The progress is tracked within the following github issue: https://github.com/JetBrains/kotlin-native/issues/1446
