I am trying to setup curl in my multiplatform project by following this guide:
<https://kotlinlang.org/docs/curl.html#generate-bindings>

But when I try to add Interop to host targets , it doesn’t get recognised by IDE….

Any help is appreciated!

I am struggling with this error: (when I don’t enable interop)

Here is a build file that you could look into:
<https://github.com/sellmair/mpp-issue-bootstrap/blob/kt-40975-i2/p2/build.gradle.kts>

<https://github.com/sellmair/mpp-issue-bootstrap/blob/kt-39324-hierarchical-commonization-it-1/p1/build.gradle.kts>

Maybe this branch also helps

Thanks <@UF3V7CF4M>, I will look into those!

And here would be a sample project for libcurl exactly, that I wrote for integration testing :relaxed: :thumbsup:

Ping me if you need help, or have any questions or ideas :thumbsup:

<@UF3V7CF4M> I enabled cInterop but now getting `fatal error: 'curl/curl.h' file not found`

In those sample projects I put the header files into the repository!
You can either use headers on your machine coming from any libcurl installation, or do the same as me. For personal projects, I would also just put the headers into the repo!

See: <https://github.com/JetBrains/kotlin/tree/master/libraries/tools/kotlin-gradle-plugin-integration-tests/src/test/resources/testProject/commonizeCurlInterop/libs/include/curl|https://github.com/JetBrains/kotlin/tree/master/libraries/tools/kotlin-gradle-plug[…]st/resources/testProject/commonizeCurlInterop/libs/include/curl>

Will see, I am new to Kotlin/Native so forgive me for asking stupid questions or asking things which for you might be common sense:no_mouth::upside_down_face:

<@UF3V7CF4M> I added the headers in repo and done required changes, CInterops Tasks Completed Successfully All targets Except *linuxX64* compile successfully

But LinuxX64 still fails with error:

`&gt; Task :linkDebugTestLinuxX64`
`e: /Users/shabinder/.konan/dependencies/clang-llvm-apple-8.0.0-darwin-macos/bin/ld.lld invocation reported errors`

`The /Users/shabinder/.konan/dependencies/clang-llvm-apple-8.0.0-darwin-macos/bin/ld.lld command returned non-zero exit code: 1.`
`output:`
`ld.lld: error: unable to find library -lcurl`

<@UF3V7CF4M> Just Removing LinuxX64 as a Target Solved All Build Errors!

If You want to look at a *reproducer* , here you go : <https://github.com/Shabinder/youtube-api-dl>

but I want to have LinuxX64 as a target , and I get a feel that the issue is related to my Build Machine ….., if Possible,Can you <@UF3V7CF4M> try building on yours if you get same error or not.

I think the problem is that you also need the binary for linux on your machine to link against!
Do you have a curl binary on your hands for linuxx64?

How do I check that? Do I have to download Curl for linux and link manually using compilerOpts/LinkerOpts?

If yes how do I do that?
