我正在尝试在我的新Macbook上构建一个项目,该项目之前通常是在Linux计算机上构建的。

首先,当我运行cmake时,我得到以下内容:

-- The C compiler identification is Clang 5.1.0
-- The CXX compiler identification is Clang 5.1.0
-- Check for working C compiler: /usr/bin/cc
-- Check for working C compiler: /usr/bin/cc -- works
-- Detecting C compiler ABI info
-- Detecting C compiler ABI info - done
-- Check for working CXX compiler: /usr/bin/c++
-- Check for working CXX compiler: /usr/bin/c++ -- works
-- Detecting CXX compiler ABI info
-- Detecting CXX compiler ABI info - done
-- Performing Test HAVE_CLOCK_GETTIME
-- Performing Test HAVE_CLOCK_GETTIME - Failed
-- Boost version: 1.55.0
-- Found the following Boost libraries:

-- Could NOT find Doxygen (missing:  DOXYGEN_EXECUTABLE) 
-- -> doxygen not found -> api-doc will not be created
-- Configuring done
-- Generating done
-- Build files have been written to: /path/to/folder

然后当我运行make时,它会一直运行到30%左右然后会因此错误而停止:

/path/to/project/lib/helpers.cpp:555:2: error: use of undeclared identifier 'gettimeofday'
        gettimeofday(&tv, NULL);
        ^
1 error generated.
make[2]: *** [lib/CMakeFiles/genom.dir/helpers.cpp.o] Error 1
make[1]: *** [lib/CMakeFiles/genom.dir/all] Error 2
make: *** [all] Error 2

我在线查看了一些建议,可以将clock_gettime(CLOCK_REALTIME, &t);更改为clock_get_time(CLOCK_REALTIME, &t);

但他们没有工作。

您提供的错误消息表明未包含gettimeofdayclock_gettime与您的关系无法从您提供的信息中说出来。

快速搜索这个产量,gettimeofday应该可用(它是POSIX的一部分)。 您有#include <sys/time.h>Apple Docs)还是#include <sys/types.h>SO Answer)?
