Hi. When I try to build binaries for Linux on MacOS I get error ld.lld: error: unable to find library -lcurl

[Giorgi]

It is a small project that uses ktor client and curl implementation("io.ktor:ktor-client-curl")

[Giorgi]

Here is the build file for root project

plugins {
    kotlin("multiplatform") version "1.9.21"
}

group = "org.example"
version = "1.0-SNAPSHOT"

repositories {
    mavenCentral()
}

kotlin {
    jvmToolchain(17)
    macosX64()
    linuxX64()
    mingwX64()

    sourceSets {
        val commonMain by getting {
            dependencies {
                implementation(project.dependencies.platform("io.ktor:ktor-bom:2.3.7"))
                implementation("io.ktor:ktor-client-auth")
                implementation("io.ktor:ktor-client-encoding")
                implementation("io.ktor:ktor-client-curl")
                implementation("io.ktor:ktor-client-logging")
                implementation("io.ktor:ktor-client-content-negotiation")
                implementation("io.ktor:ktor-serialization-kotlinx-json")
                implementation("com.squareup.okio:okio:3.7.0")
                implementation("org.jetbrains.kotlinx:kotlinx-datetime:0.4.1")
                implementation("org.jetbrains.kotlinx:kotlinx-coroutines-core:1.7.3")
                implementation("org.jetbrains.kotlinx:kotlinx-io-core:0.3.0")
            }
        }
        val commonTest by getting {
            dependencies {
                implementation(kotlin("test"))
                implementation("org.jetbrains.kotlinx:kotlinx-coroutines-test:1.7.3")
            }
        }
    }
}

Here is the one for another module that includes rootProject

plugins {
    kotlin("multiplatform") version "1.9.21"
//    id("org.jetbrains.kotlin.jvm")
//    id("com.jakewharton.mosaic") version "0.10.0"
}

version = "1.0"

repositories {
    mavenCentral()
}

kotlin {
    jvmToolchain(17)
    macosX64 {
        binaries {
            executable {
                baseName = "mpp-macosX64"
                entryPoint = "hidden"
            }
        }
    }

    linuxX64 {
        binaries {
            executable {
                baseName = "mpp-linuxX64"
                entryPoint = "hidden"
            }
        }
    }

    mingwX64 {
        binaries {
            executable {
                baseName = "mpp-mingwX64.exe"
                entryPoint = "hidden"
            }
        }
    }

    sourceSets {
        val commonMain by getting {
            dependencies {
                implementation(rootProject)
                implementation("com.github.ajalt.clikt:clikt:4.2.1")
            }
        }
    }
}

tasks.withType<Wrapper> {
    gradleVersion = "8.1.1"
    distributionType = Wrapper.DistributionType.BIN
}

When I run linuxX64Binaries this is the output

Hey, you need to install the curl or libcurl package on your system.
