我正在尝试构建我的项目以包含生产源(在src子文件夹中)和测试(在test子文件夹中).我正在使用CMake来构建它.作为一个最小的例子,我有以下文件:
的CMakeLists.txt:
cmake_minimum_required (VERSION 2.8)
project (TEST)
add_subdirectory (src)
add_subdirectory (test)
SRC /的CMakeLists.txt:
add_executable (demo main.cpp sqr.cpp)
SRC/sqr.h
#ifndef SQR_H
#define SQR_H
double sqr(double);
#endif // SQR_H
SRC/sqr.cpp
#include "sqr.h"
double sqr(double x) { return x*x; }
src/main.cpp - 使用sqr,并不重要
测试/的CMakeLists.txt:
find_package(Boost COMPONENTS system filesystem unit_test_framework REQUIRED)
include_directories (${TEST_SOURCE_DIR}/src)
ADD_DEFINITIONS(-DBOOST_TEST_DYN_LINK)
add_executable (test test.cpp ${TEST_SOURCE_DIR}/src/sqr.cpp)
target_link_libraries(test
${Boost_FILESYSTEM_LIBRARY}
${Boost_SYSTEM_LIBRARY}
${Boost_UNIT_TEST_FRAMEWORK_LIBRARY}
)
enable_testing()
add_test(MyTest test)
测试/ TEST.CPP:
#define BOOST_TEST_MODULE SqrTests
#include <boost/test/unit_test.hpp>
#include "sqr.h"
BOOST_AUTO_TEST_CASE(FailTest)
{
BOOST_CHECK_EQUAL(5, sqr(2));
} …我是CMake的初学者.我的环境有几个项目,如:
project
|------ CMakeLists.txt (The main Cmake)
|------ ProjectA
| |----- .cpp files
| |----- .hpp files
| |----- CMakeList.txt
|------ ProjectB
| |----- .cpp files
| |----- .hpp files
| |----- CMakeList.txt
|
|------ build
| |----- CMakeStuff
|------ bin
| |---- executables
|------ lib
| |---- libwhatever.a
|------ db
|---- Database stuff
我想为每个项目使用一个构建目录,如上所示.更好的是,它可以分为多个子项目,例如build/projectA,build/ProjectB如果我需要重建一个项目,我可以删除整个build/Project文件,一切都消失了,新的Cmake将再次构建它.
我在配置CMAKE时遇到了困难.
我在项目文件夹中的原始CMakeList.txt:
cmake_minimum_required(VERSION 3.2.2.)
set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/../lib)
set(CMAKE_LIBRARY_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/../lib)
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/../bin)
project(projectA)
set(CMAKE_BUILD_TYPE Debug)
file(GLOB SOURCES "*.cpp")
add_library(commonmessage …C:\blah\duh\bin\Android>"C:\Program Files (x86)\CMake\bin\cmake.exe" --build . --target SysTest --use-stderr -- -j 8
我有上面的CMake构建命令.我明白了 - 建造.将从当前目录中的Makefile构建.但是选项-target SysTest和-j 8有什么作用呢？这是--build的CMake文档,但我承认我不理解--target的使用.
--build <dir>
Build a CMake-generated project binary tree.
This abstracts a native build tool’s command-line interface with the following options:
<dir> = Project binary directory to be built.
--target <tgt> = Build <tgt> instead of default targets.
--config <cfg> = For multi-configuration tools, choose <cfg>.
--clean-first = Build target 'clean' first, then build.
(To clean only, use --target 'clean'.)
--use-stderr = Ignored. Behavior is …我有一个具有以下文件结构的项目:
project
|
|-------> lib1
| |----> lib1.h
|
|-------> lib2
| |----> lib2.h
|
|-------> main.cc
这两个库lib1,并lib2只包含头文件,同时lib2.h包括lib1.h,和main.cc包括lib2.h.
我现在如何为这个项目编写cmake文件？我试图创建一个接口库的lib2,但是编译器无法找到lib1.h.以下是我的cmake文件的内容:
lib2的CMakeLists.txt:
add_library(lib2 INTERFACE)
target_sources(lib2 INTERFACE lib2.h)
target_include_directories(lib2 INTERFACE ../lib1/lib1.h)
整个项目的CMakeLists.txt:
add_executable(project main.cc)
target_link_libraries(project lib2)
cmake文件中有什么问题？
在Catch2的示例中，我尝试使用cmake项目结构如下运行该示例：
/factorial
+-- CMakeLists.txt
+-- /bin
+-- /include
| +-- catch.hpp
| +-- fact.hpp
+-- /src
| +-- CMakeLists.txt
| +-- fact.cpp
+-- /test
+-- CMakeLists.txt
+-- test_fact.cpp
fact.cpp：
unsigned int factorial( unsigned int number ) {
return number <= 1 ? number : factorial(number-1)*number;
}
fact.hpp：
#ifndef FACT_H
#define FACT_H
unsigned int factorial(unsigned int);
#endif
test_fact.cpp：
#define CATCH_CONFIG_MAIN
#include "catch.hpp"
#include "fact.hpp"
TEST_CASE( "factorials are computed", "[factorial]" ) {
REQUIRE( factorial(1) == …我有一个简单的cmake项目,我无法在OS X 10.8.4上编译.cmake/make过程在Linux上运行良好但在OS XI上遇到此错误:
Linking CXX static library libImageFilter.a
ar: no archive members specified
...
make[2]: *** [lib/libImageFilter.a] Error 1
make[1]: *** [lib/CMakeFiles/ImageFilter.dir/all] Error 2
make: *** [all] Error 2
我在两个平台上都使用Eclipse CDT4 Generator Unix MakeFile.这似乎与两个系统上的ar之间的差异有关.但是,我在谷歌找不到太多帮助我排除故障.
