【问题描述】：
我正在尝试在 Windows 上使用 msys2 通过 ndk 工具链为 Android 构建 gmp。但我不断收到此错误：
configure: error: Cannot find a build system compiler
我什至不确定什么是构建系统编译器？ NDK 中的哪个可执行文件？如何指定？

【问题讨论】：
-
GMP 想要构建一些在你的 windows 机器上运行的程序，以便它可以运行它们来生成一些表，然后将它们包含在你的 android 库中。所以它还需要一个本机编译器。至少我是这样理解这个信息的。 gmplib.org/manual/Build-Options.html#index-CC_005fFOR_005fBUILD
-
尝试在日志文件中查找此步骤失败的原因：
checking build system compiler C:/Developer/AppPlugin/build/android/toolchain-arm-21/bin/arm-linux-androideabi-clang... no。 “配置”脚本会留下一些日志。为了检查编译器，configure 脚本编译了一些代码，日志中应该有特定的错误。
