A reliable check is to use the CMAKE_<LANG>_COMPILER_ID variables. E.g., to check the C++ compiler: if (CMAKE_CXX_COMPILER_ID STREQUAL "Clang") # using Clang elseif (CMAKE_CXX_COMPILER_ID STREQUAL "GNU") # using GCC elseif (CMAKE_CXX_COMPILER_ID STREQUAL "Intel") # using Int...
collect2: error: ld returned 1 exit status, 说明在生成位置无关代码时候碰到了问题,但是我们并不慌,可以在生成目标文件.o的时候,添加-fPIC,经过三个命令,即可得到.so,分别为gcc -c ./files2/mean.cpp -o ./libs/mean.o -Iincludes2 -Ibase -fPIC,gcc -c ./files1/max_score.cpp -o ./libs/ma...
一般在Ubuntu上编译运行,只需要设置为gcc/g++即可。 编译工具链都是由厂商提供,用户只需要在编译脚本配置即可。设置交叉编译工具链方式如下: ## 绝对路径 set(CMAKE_C_COMPILER "xxx/arm-linux-gcc") set(CMAKE_CXX_COMPILER "xxx/arm-linux-g++") 设置浮点运算处理方式 在某些gcc编译器会检查软浮点和硬浮点...
