Question

正在运行cmake -DCMAKE_TOOLCHAIN_FILE=ceres-solver/cmake/iOS.cmake -DCMAKE_CXX_FLAGS="-stdlib=libc++" -DEIGEN_INCLUDE_DIR=/usr/local/Cellar/eigen -DIOS_PLATFORM=OS ceres-solver

给了我这些错误

即使我将CXX11设置为ON，我也会得到同样的错误。我该怎么办？

假设我这样做了，我是否只是运行make install来获取libceres.a文件？

非常感谢。

这不是C ++ 11错误，请注意错误

CMake错误：生成器：执行make失败。命令是：＆＃34; CMAKE_MAKE_PROGRAM＆＃34; ＆＃34; cmTC_3feba /快＆＃34;

CMake正在尝试通过编译几个短程序片段来确定各种c ++ 11功能的存在，并且由于一些与Make相关的问题而无法这样做（你是否已经安装了？Xcore命令行工具？）最终得出的结论是c ++ 11不可用。

这里需要解决的问题是看看Make在你的系统上发生了什么。

在iOS上安装ceres-solver
