CMake(Android工具链) - 运行链接命令时出错:没有这样的文件或目录

Question

我正在使用CMake构建Android项目."android.toolchain.cmake"工具链用于构建项目.

所有环境变量都按照android cmake的用法部分所述进行设置.以下选项变量被设置为环境变量ANDTOOLCHAIN ANDROID_STANDALONE_TOOLCHAIN ANDROID_ABI ANDROID_NATIVE_API ANDROID_STL CC和CXX分别指向androideabi-gcc和androideabi-g ++

CMAKE成功生成了Make文件,但当我"生成"项目时,它正在抛出"错误运行链接命令:没有这样的文件或目录".

link.txt的详细信息如下

link.txt文件中的所有文件都指向正确的目录/路径,并且任何文件路径都没有问题.在link.txt文件中,而不是使用编译器的实际路径,它使用CMAKE_C_COMPILER.我认为这是创建问题,因为"make"命令无法找到编译器的实际路径.

任何帮助解决这个问题将不胜感激.

Answer 1

我最近遇到了同样的问题,并且无法弄清楚为什么它无法用正确的路径替换CMAKE_C_COMPILER.所以我最终做的是修改android.toolchain.cmake,其中设置了CMAKE_CXX_CREATE_YYY.从

set( CMAKE_CXX_CREATE_SHARED_LIBRARY "<CMAKE_C_COMPILER> ...")
set( CMAKE_CXX_CREATE_SHARED_MODULE  "<CMAKE_C_COMPILER> ...")
set( CMAKE_CXX_LINK_EXECUTABLE       "<CMAKE_C_COMPILER> ...")

至

set( CMAKE_CXX_CREATE_SHARED_LIBRARY "<CMAKE_CXX_COMPILER> ...")
set( CMAKE_CXX_CREATE_SHARED_MODULE  "<CMAKE_CXX_COMPILER> ...")
set( CMAKE_CXX_LINK_EXECUTABLE       "<CMAKE_CXX_COMPILER> ...")

并且CMake能够生成正确的link.txt.希望这可以帮助.
