A modern programming language that makes developers happier.

&gt;  Install the <https://curl.se/download.html|curl library>
however, I am a bit confused and annoyed by this step as
1, this shouldnt be necessary, developers shouldnt download and install arbitrary things just to make their machine able to build a project, this is literally what tools like gradle are meant for, why is this not handled by gradle?!
2, the link is just a download page, which gives absolutely no information as to how to "install" (pretending that even makes sense) the package
3, I have curl already "installed"

even if you have the `curl` binary installed, that doesn't mean you have the development libraries

how to get those depends on platform/distribution

it's not in Maven because that's not how native dependencies are traditionally distributed

(and I don't think Maven could cope with the huge diversity in Linux distributions anyway)

after following <https://github.com/JetBrains/kotlin/blob/master/kotlin-native/samples/libcurl/README.md>
I can run task `runDebugExecutableMingwX64` succesfully, but task `assemble` has a similar error ".konan\dependencies\msys2-mingw-w64-x86_64-1\bin\ld.gold: error: cannot find -lcurl"

because you will need a Windows libcurl in order to build for Windows

I'm not sure how to set up the sysroot for cross-compiling though

but I assume I already have a windows libcurl because running the application works

`assemble` works if I disable the linux build

however, obviously, that is not acceptable

hmm. then perhaps run just wants a shared library, assemble wants a static library, and you only have one of them

I cannot help with anything Windows-related; all I can say is that dealing with native libraries is a pain in every language, even the most native language of C

wait, are you working on Windows? then you'll need a Linux libcurl in order to build for Linux (and `assemble` builds for enabled targets)… and there's not just *one* Linux libcurl… it is challenging to make redistributable Linux binaries

I am working on windows, but I'd be deploying on AWS Lambda, those are currently the only runtimes that really need to be supported, so I dont necessarily have to have a fully redistributable linux binary, just for the one target that runs the AWS Lambda containers

looking at issues related to libcurl and aws(lambda), I find that the solution is to install libcurl-devel, but after installing it via <https://www.msys2.org/> using `pacman -S libcurl-devel` it still cant find the package...

usually you need to build from a Linux system or container containing the same or compatible versions as your target - those applies to all native development. now that's not completely necessary for Kotlin because Konan fixes the glibc it build against, but that doesn't extend to external libraries. you will need to get the development version of whatever libcurl AWS lambda has, or deploy your own with your program

msys2 pacman only installs the windows curl library

I am now trying to set up a build pipeline to build the application from an AWS Lambda instead of local machine... which would be the end goal, but building and deploying from local machine would definitely be a nice bonus, especially during the current phase which is just exploring how things work
