我在针对 androidNativeX64、androidNativeArm64、linuxArm64、linuxX64 目标进行编译时遇到问题。

我有一个相当复杂的设置（多模块 gradle 项目）。

我有核心模块 sqlx4k 和 sqlx4k-mysql , sqlx4k-postgres 3 个客户端模块 sqlx4k-sqlite （我们称之为 impl 模块）。

每个模块都“包装”了一个 Rust 库，该库会创建一个静态库（ .a )

.
 build-logic
    multiplatform-convention
 sqlx4k
    rust_lib -> produces static lib libsqlx4k.a
    src
 sqlx4k-mysql
    examples
    rust_lib -> produces static lib libsqlx4k_mysql.a
    src
 sqlx4k-postgres
    examples
    rust_lib -> produces static lib libsqlx4k_postgres.a
    src
 sqlx4k-sqlite
     examples
     rust_lib -> produces static lib libsqlx4k_sqlite.a
     src

在每个 impl 模块（例如 sqlx4k-mysql）中，rust 包都包含 sqlx4k/rust_lib as 依赖项。一般来说， sqlx4k （核心模块）包含 rust 和 kotlin 代码库的通用代码。

当然，每个 impl 模块都包含核心 kotlin 模块 sqlx4k .

每个模块 .def 针对每个目标都有几个文件。以下是目标的示例 macosArm64 ：

package = sqlx4k.impl
headers = sqlx4k_postgres.h
compilerOpts = -I./rust_lib/target

staticLibraries = libsqlx4k_postgres.a
libraryPaths = ./rust_lib/target/aarch64-apple-darwin/release

一般来说，在每个 impl 模块中，我只链接来自同一个模块的静态 rust 库（我不链接 libsqlx4k.a ），因为它已经打包在每个 impl 静态库中。

以下设置仅对 Linux（也包括 Android）目标失败。对于 Apple 目标，运行完全正常。

错误是：

我认为这很奇怪。因为这些符号是每个 impl 模块创建的绑定。

完整项目可以在这里找到： https://github.com/smyrgeorge/sqlx4k

更新：

我刚刚看到如果我跑

./gradlew clean :sqlx4k-sqlite:build -Ptargets=linuxArm64

完美编译 linuxArm64 而构建

但是，如果我运行：

./gradlew clean :sqlx4k-sqlite:build -Ptargets=linuxArm64,linuxX64

这将构建 linuxArm64 并 linuxX64 失败并出现上述错误。

错误出现在 :sqlx4k-sqlite:compileNativeMainKotlinMetadata 任务上。可能在编译过程中写入了公共文件，由于是并行发生的，因此失败。虽然对于苹果目标来说没有问题。
