Hey, I try to build https://github.com/JetBrains/kotlin/tree/master/kotlin-native/tools/benchmarksAnalyzer and have not played with Kotlin/Native for a very long time so sorry if those are basic questions. When importing the project in IDEA, I had both

import platform.posix.*

and

import libcurl.*

in red (unresolved reference) in

kotlin/kotlin-native/tools/benchmarksAnalyzer/src/main/kotlin-native/org/jetbrains/analyzer/Utils.kt

. I found in Kotlin Native README that I had to run

./gradlew :kotlin-native:dist :kotlin-native:distPlatformLibs

at the root of the

kotlin

project to get

import platform.posix.*

resolving. This part is now fixed. But I am blocked for libcurl:

> Task :compileNativeMainKotlinMetadata FAILED
e: /home/seb/playground/kotlin/kotlin-native/tools/benchmarksAnalyzer/src/main/kotlin-native/org/jetbrains/analyzer/Utils.kt: (10, 8): Unresolved reference: libcurl

I have libcurl installed (Archlinux) and headers are in

/usr/local/include

. I tried to modify the build to specify `compilerOpts '-I/usr/local/include'`:

fromPreset(presets.linuxX64, 'linux') {
            compilations.main.cinterops {
                libcurl {
                    compilerOpts '-I/usr/local/include'
			        includeDirs.headerFilterOnly '/usr/include', '/usr/local/include'
                }
            }
        }

But still the same error. When I try to build the project with

gradle build

I get:

> Task :compileNativeMainKotlinMetadata FAILED
e: /home/seb/playground/kotlin/kotlin-native/tools/benchmarksAnalyzer/src/main/kotlin-native/org/jetbrains/analyzer/Utils.kt: (10, 8): Unresolved reference: libcurl

The command

gradle cinteropLibcurlLinux

seems to run properly and invokes

cinterop -o /home/seb/playground/kotlin/kotlin-native/tools/benchmarksAnalyzer/build/classes/kotlin/linux/main/cinterop/benchmarksAnalyzer-cinterop-libcurl.klib -target linux_x64 -def /home/seb/playground/kotlin/kotlin-native/tools/benchmarksAnalyzer/src/nativeInterop/cinterop/libcurl.def -compiler-option -I/usr/local/include -Xmodule-name benchmarksAnalyzer-cinterop-libcurl

which seems to work fine. Could somebody point me to what I am missing to get libcurl resolving both in IDEA and with

gradle build

?

Hello! There are some problems now connected with HMPP. You can use flag as here https://github.com/JetBrains/kotlin/blob/rrn/lepilkina/macosArm64_benchs/kotlin-native/tools/benchmarksAnalyzer/gradle.properties#L3 (I haven't yet commited to master because I wanted to do some other changes in this branch) but pay attention that in this case you need full K/N bundle build (not only dist) or you can disable HMPP with

kotlin.mpp.hierarchicalStructureSupport=false

(in same file). Sorry for inconvenient state of this app in master branch, this will be fixed soon

kotlin.mpp.hierarchicalStructureSupport=false

made the trick, thanks!

Very surprising that HMPP doesn't work in this case since it is supposed to work with Kotlin Native programs that contain one or more Linux targets. My understanding is that HMPP works with Linux targets in a Kotlin Native program, but not with a Kotlin Native library although that should be resolved in the near future.

HMPP works when adding

kotlin.mpp.enableCInteropCommonization=true

in this case. This is case of master branch and features are enabling step by step.
