cmake交叉编译错误  发帖心情 Post By:2019-4-2 17:34:00 [只看该作者]

使用 ESM6802-toolchain-x86_64-qt5-8.sh 安装编译工具链。使用默认安装目录/opt/fsl-imx-x11/4.1.15-2.0.1/sysroots/


编译目录如下面

cmake-test

|-- build
|-- CMakeLists.txt
|-- cross-compile.txt
`-- hello.cpp

使用其他家的交叉编译器没有问题。使用你们家的出现如下编译错误

newrt@newrt-desktop:~/Documents/cmake-test/build$ cmake -DCMAKE_TOOLCHAIN_FILE=../cross-compile.txt ..

使用TI的交叉编译器

回到错误的问题点

》》》cannot find crt1.o: No such file or directory

发现在/opt/fsl-imx-x11/4.1.15-2.0.1/sysroots/cortexa9hf-neon-emtronix-linux-gnueabi/usr/lib/crt1.o。

那就是我哪里设置问题。但是cross-compile中该设的变量我都设置啦。那就奇怪了???

你好,如果使用cmake编译的话,不需要对工具链做任何设置,所以cross-compile.txt是不需要的,只需要在CmakeList设置工程的名称,源文件等就行了。然后使用source命令加载工具链安装目录下的environment文件,就可以直接在工程中使用cmake .生成makefile了。
