我正在Linux上编译,但未来会在Mac和Windows上编译。
# Copies the given files to the destination directory
defineTest(copyToDestdir) {
files = $$1
for(FILE, files) {
DDIR = $$DESTDIR
# Replace slashes in paths with backslashes for Windows
win32:FILE ~= s,/,\\,g
win32:DDIR ~= s,/,\\,g
QMAKE_POST_LINK += $$QMAKE_COPY $$quote($$FILE) $$quote($$DDIR) $$escape_expand(\\n\\t)
}
export(QMAKE_POST_LINK)
}
接着按如下方式使用:
copyToDestdir($$OTHER_FILES) # a variable containing multiple paths
copyToDestdir(run.sh) # a single filename
copyToDestdir(run.sh README) # multiple files
Qt 5.6 添加了这个作为一个未记录的功能:
CONFIG += file_copies
想一个名称来描述您想要复制的文件:
COPIES += myDocumentation
列出要复制的文件,包括在其 .files
成员中:
myDocumentation.files = $$files(text/docs/*.txt)
在.path
成员中指定目标路径:
myDocumentation.path = $$OUT_PWD/documentation
可选地指定要从源路径中删除的基础路径:
myDocumentation.base = $$PWD/text/docs
它的工作原理基本上与其他答案所述的许多方法相同。请参见file_copies.prf,了解详细信息。
该接口与INSTALLS
非常相似。

会扩展为空字符串。${FILE}

defineReplace(fileCopyDestination) {

它是如何工作的
第一部分定义了一个额外编译器,该编译器将从COPY_FILES
变量中读取输入文件名。接下来定义了一个函数,用于合成每个输入对应的输出文件名。然后我们定义了用于调用此“编译器”的命令,这取决于我们使用的shell类型。
然后我们定义了一个额外的makefile目标copy_files.cookie
,它依赖于目标compiler_copy_files_make_all
。后者是qmake为我们在第一步中定义的额外编译器生成的目标名称。这意味着当构建copy_files.cookie
目标时,它将调用额外的编译器来复制文件。
CONFIG += copy_files
COPY_FILES
变量中:COPY_FILES += docs/*.txt
我发现我需要修改sje397提供的答案,用于与Qt5 Beta1和QtCreator 2.5.2一起使用。在构建完成后,我使用此脚本将qml文件复制到目标目录作为额外步骤。
我的.pro文件中有以下代码
OTHER_FILES += \
Application.qml
# Copy qml files post build
win32 {
DESTDIR_WIN = $${DESTDIR}
DESTDIR_WIN ~= s,/,\\,g
PWD_WIN = $${PWD}
PWD_WIN ~= s,/,\\,g
for(FILE, OTHER_FILES){
QMAKE_POST_LINK += $$quote(cmd /c copy /y $${PWD_WIN}\\$${FILE} $${DESTDIR_WIN}$$escape_expand(\\n\\t))
}
}
unix {
for(FILE, OTHER_FILES){
QMAKE_POST_LINK += $$quote(cp $${PWD}/$${FILE} $${DESTDIR}$$escape_expand(\\n\\t))
}
请注意,我使用$$PWD_WIN来提供源文件的完整路径,以便将其复制到目标位置。
include($$PWD/functions.pri) #optional
copyFile($$PWD/myfile1.txt, $$DESTDIR/myfile1.txt)
copyFile($$PWD/README.txt, $$DESTDIR/README.txt)
copyFile($$PWD/LICENSE, $$DESTDIR/LICENSE)
copyDir($$PWD/redist, $$DESTDIR/redist) #copy "redist" folder to "$$DESTDIR"
但是,为了使其工作,需要在某处定义下面的内容(来自XD
框架),比如在functions.pri
文件中:
# --------------------------------------
# This file defines few useful functions
# --------------------------------------
#copyDir(source, destination)
# using "shell_path()" to correct path depending on platform

#the qmake generated MakeFile contains "first" and we depend that on "xd_copydir"
first.depends *= xd_copydir
QMAKE_EXTRA_TARGETS *= first xd_copydir

除了Jake's answer和@Phlucious评论中提到的方法,还可以使用qmake的defineReplace
函数,这个函数适用于这种情况。在使用提供的示例后,我遇到了一个问题,即qmake跳过了我添加的最后一个链接操作。可能是变量导出的问题,尽管内容一直看起来很好。长话短说,这里是修改后的代码
defineReplace(copyToDir) {
files = $$1
DIR = $$2
LINK =
for(FILE, files) {
LINK += $$QMAKE_COPY $$shell_path($$FILE) $$shell_path($$DIR) $$escape_expand(\\n\\t)
}
return($$LINK)
}
这个通用的复制函数可以被一些方便的函数使用,比如这个。
defineReplace(copyToBuilddir) {
return($$copyToDir($$1, $$OUT_PWD))
}
第二个只需要一个参数(一个或多个文件),并提供了一个固定的路径。基本上与参考答案相同。
但现在请注意调用的区别。
QMAKE_POST_LINK += $$copyToBuilddir(deploy.bat)
正如您所看到的,您可以将返回的命令附加到QMAKE_PRE_LINK以获得更大的灵活性。
首先,定义以下两个函数以支持Windows/Unix。
defineReplace(nativePath) {
OUT_NATIVE_PATH = $$1
# Replace slashes in paths with backslashes for Windows
win32:OUT_NATIVE_PATH ~= s,/,\\,g
return($$OUT_NATIVE_PATH)
}
# Copies the given files to the destination directory
defineReplace(copyToDestDirCommands) {
variable_files = $$1
files = $$eval($$variable_files)
DDIR = $$nativePath($$2)
win32:DDIR ~= s,/,\\,g
POST_LINK = echo "Copying files to $$DDIR" $$escape_expand(\\n\\t)
win32 {
POST_LINK += $$QMAKE_MKDIR $$quote($$DDIR) 2>&1 & set errorlevel=0 $$escape_expand(\\n\\t)
}
!win32 {
POST_LINK += $$QMAKE_MKDIR -p $$quote($$DDIR) $$escape_expand(\\n\\t)
}
for(ORIGINAL_FILE, files) {
FILE = $$nativePath($$ORIGINAL_FILE)
POST_LINK += $$QMAKE_COPY $$quote($$FILE) $$quote($$DDIR) $$escape_expand(\\n\\t)
}
return ($$POST_LINK)
}
接下来,您可以使用以下代码调用之前定义的函数将文件复制到特定文件夹,并在必要时创建目录。该代码已在Win32下测试通过,欢迎进行Linux测试。
BATOS_FILES = \
$$BATOS_BIN_ROOT/batos-core.dll \
$$BATOS_BIN_ROOT/batos-pfw.dll \
$$BATOS_BIN_ROOT/dre.dll \
$$BATOS_BIN_ROOT/log4qt.dll
QMAKE_POST_LINK += $$copyToDestDirCommands(BATOS_FILES, $$DESTDIR)
BATOS_PLUGINS_FILES = \
$$BATOS_BIN_ROOT/plugins/com.xaf.plugin-manager.dll \
$$BATOS_BIN_ROOT/plugins/org.commontk.eventadmin.dll
QMAKE_POST_LINK += $$copyToDestDirCommands(BATOS_PLUGINS_FILES, $$DESTDIR/plugins)
$$OUT_PWD
代替$$DESTDIR
以使它能够工作。参考一下,$$OUT_PWD
是程序构建的文件夹,而$$PWD
是正在构建程序的文件夹 -换句话说,它就是.pro文件所在的位置。 - LogandefineTest
而不是defineReplace
?我无法通过defineReplace
让 qmake 构建此项目,但我不明白为什么。文档中说:“这种类型的函数只应在条件表达式中使用”,但在这种情况下并不正确。 - PhluciousQMAKE_POST_LINK
行为QMAKE_POST_LINK += $$QMAKE_COPY $$quote($$FILE) $$quote($$DDIR)$$escape_expand(\\n\\t\\n\\t)
。 多个换行符是必要的,因为Windows路径可能以\\
结尾,但这会转义该行并使其继续到下一行。 - Ross Rogers$$quote
替换为$$shell_quote
,将$$DESTDIR
替换为$$OUT_PWD
。 - retif
