CMake+SVN或Hg生成版本号
原来的CMake需要用shell脚本生成SVN版本号,再作为cmake参数传入。CMake调用脚本示例: #!/bin/sh # cmake.shServerCodeRoot=~/Code/Server
CodeRevNum=`svn info ${ServerCodeRoot} | grep Revision | awk -F' ' '{ print $2 }'` cmake S{ServerCodeRoot} -DCMAKE_BUILD_TYPE=Release -DVERSION_REVISION=S{CodeRevNum}CMakeLists.txt中如下配置:
configure_file( "Version.h.in" "Version.h" )Version.h.in如下: #include <string> const std::string VERSION_MAJOY("1"); const std::string VERSION_MINOR("0"); const std::string VERSION_REVISION("@VERSION_REVISION@");Linux下执行cmake.sh会自动替换SVN版本号。
现改为用FIND_PACKAGE(Subversion)方式,不必用shell脚本生成SVN版本号,
并且在Windows上也可以生成版本号, cmake调用时不必传VERSION_REVISION参数。CMakeLists.txt改为(参考了开源网游ryzom的CMake):
SET(ROOT_DIR ${PROJECT_SOURCE_DIR}) IF(EXISTS "${ROOT_DIR}/.svn/") FIND_PACKAGE(Subversion)IF(SUBVERSION_FOUND)
Subversion_WC_INFO(${ROOT_DIR} Project) SET(VERSION_REVISION ${Project_WC_REVISION}) ENDIF(SUBVERSION_FOUND) ENDIF(EXISTS "${ROOT_DIR}/.svn/")CONFIGURE_FILE(
"Version.h.in" "Version.h" ) 如果不是SVN, 而是用Hg, 可用如下脚本: IF(EXISTS "${ROOT_DIR}/.hg/") FIND_PACKAGE(Mercurial)IF(MERCURIAL_FOUND)
Mercurial_WC_INFO(${ROOT_DIR} ER) SET(REVISION ${ER_WC_REVISION}) SET(CHANGESET ${ER_WC_CHANGESET}) SET(BRANCH ${ER_WC_BRANCH}) ENDIF(MERCURIAL_FOUND) ENDIF(EXISTS "${ROOT_DIR}/.hg/")
