我在*.pro
文件中有一个自定义构建目标:
docs.commands = doxygen $$PWD/../docs/Doxyfile
QMAKE_EXTRA_TARGETS += docs
POST_TARGETDEPS += docs
作为后构建事件运行Doxygen
。问题是,如果某人构建项目并且尚未安装doxygen
,则构建失败。是否可以检查是否在构建项目的计算机上安装了doxygen
,以便仅在安装doxygen
并添加到系统PATH
?
doxygen
命令。使用qmake,您可以尝试以下方法:
DOXYGEN_BIN = $$system(which doxygen)
isEmpty(DOXYGEN_BIN) {
message("Doxygen not found")
}
另一个选项可能是以下一个:
DOXYGEN_BIN = $$system( echo $$(PATH) | grep doxygen )
isEmpty(DOXYGEN_BIN) {
message("Doxygen not found")
}
btw,如果您使用的是cmake
您可以使用
实现这一目标find_package(Doxygen)
示例:
FIND_PACKAGE(Doxygen)
if (NOT DOXYGEN_FOUND)
message(FATAL_ERROR "Doxygen is needed to build the documentation.")
endif()
您在此网站中有更多信息:
http://www.cmake.org/cmake/help/v3.0/module/finddoxygen.html
在您的.pro文件上尝试一下:
# Check if Doxygen is installed on the default Windows location
win32 {
exists( "C:Program Filesdoxygenbindoxygen.exe" ) {
message( "Doxygen exists")
# execute your logic here
}
}
# same idea for Mac
macx {
exists( "/Applications/doxygen.app/ ... " ) {
message( "Doxygen exists")
}
}
update
使用@tarod答案您可以使其与以下
兼容# Check if Doxygen is installed on Windows (tested on Win7)
win32 {
DOXYGEN_BIN = $$system(where doxygen)
isEmpty(DOXYGEN_BIN) {
message("Doxygen not found")
# execute your logic here
} else {
message("Doxygen exists in " $$DOXYGEN_BIN)
}
}
# Check if Doxygen is installed on Linux or Mac (tested on Ubuntu, not yet on the Mac)
unix|max {
DOXYGEN_BIN = $$system(which doxygen)
isEmpty(DOXYGEN_BIN) {
message("Doxygen not found")
# execute your logic here
} else {
message("Doxygen exists in " $$DOXYGEN_BIN)
}
}
qt文档说:
在运行QMAKE时获得环境价值的内容,请使用$$(...)操作员...
即:
PATH_VAR = $$(PATH)
DOXYGEN = "doxygen"
contains(PATH_VAR, DOXYGEN) {
message("Doxygen found")
}
