老makefile文件转换为CMake的 [英] Converting old makefile to CMake

问题描述

我想我的旧的makefile code转换为CMake的。你可以帮我吗？这是我目前被困的部分。我不知道如何把这些参数传递到编译器。

I'm trying to convert my old makefile code to CMake. Can you help me? This is the part where I'm currently stuck. I don't know how to pass these arguments to the compiler.

COMPILE_FLAGS = -c -m32 -O3 -fPIC -w -DSOMETHING -Wall -I src/sdk/core

ifdef STATIC
    OUTFILE = "bin/test_static.so"
    COMPILE_FLAGS_2 = ./lib/ABC.a
else
    OUTFILE = "bin/test.so"
    COMPILE_FLAGS_2 = -L/usr/lib/mysql -lABC
endif

all:
    g++ $(COMPILE_FLAGS) src/sdk/*.cpp
    g++ $(COMPILE_FLAGS) src/*.cpp
    g++ -fshort-wchar -shared -o $(OUTFILE) *.o $(COMPILE_FLAGS_2)
    rm -f *.o

感谢您！

推荐答案

让我们尝试映射的Makefile 语法 CMake的：

COMPILE_FLAGS = -c -m32 -O3 -fPIC -w -DSOMETHING -Wall -I src/sdk/core

本声明直接映射到：

SET( COMPILE_FLAGS "-c -m32 -O3 -fPIC -w -DSOMETHING -Wall" )
INCLUDE_DIRECTORIES( src/sdk/core )

一个条件类型：

ifdef STATIC
  # Do something
else
  # Do something else
endif

被翻译在CMake的是这样的：

is translated in CMake in this way:

OPTION(STATIC "Brief description" ON)
IF( STATIC )
  # Do something
ELSE()
  # Do something else
ENDIF()

要修改默认的编译标志，你可以设置变量 CMAKE_＆LT; LANG＆GT; _FLAGS_RELEASE ， CMAKE_＆LT; LANG＆GT; _FLAGS_DEBUG 等，恰如其分。

To modify the default compilation flags you can set the variables CMAKE_<LANG>_FLAGS_RELEASE, CMAKE_<LANG>_FLAGS_DEBUG, etc. , appropriately.

最后一个可执行文件的编制要求您使用 ADD_EXECUTABLE 命令，它在许多CMake的教程解释。

Finally the compilation of an executable requires you to use the ADD_EXECUTABLE command, which is explained in many CMake tutorials.

在我建议你参考更多详细信息，在线文档，因为它是任何情况下，相当的解释和完整。

In any case I suggest you to refer to the online documentation for further details, as it is quite explanatory and complete.
