创建一个.pc文件

Qmake creating a .pc file

本文关键字：一个 pc 文件 创建      更新时间：2023-10-16

有人知道qmake是否可以创建。pc文件吗?我找到了一个说可以的人:http://www.qtcentre.org/threads/24422-How-can-we-create-.pc-file-automatically。但我已经尝试过了，并得到了与在帖子底部有问题的人相同的结果。我想知道是否有人知道这件事。

TEMPLATE = lib
TARGET = proc_Model
QT += declarative dbus
CONFIG += qt plugin dbus create_pc
DESTDIR = /usr/lib/
OBJECTS_DIR = .obj
MOC_DIR = .moc

TARGET = $$qtLibraryTarget($$TARGET)
INCLUDEPATH += ../common 
# Input
SOURCES +=    ../common/proc_struct.cpp 
    listitem.cpp 
    listmodel.cpp 
    process.cpp 
    proc_if.cpp
HEADERS +=  ../common/proc_struct.h 
    listitem.h 
    listmodel.h 
    process.h 
    proc_if.h

headers.path= /usr/include/proc_Model
headers.files = ../common/proc_struct.h 
    listitem.h 
    listmodel.h 
    process.h 
    proc_if.h
target.path = /usr/lib

QMAKE_PKGCONFIG_NAME = proc_Model
QMAKE_PKGCONFIG_DESCRIPTION = Model that emits process info
QMAKE_PKGCONFIG_LIBDIR = $$target.path
QMAKE_PKGCONFIG_INCDIR = $$target.path
QMAKE_PKGCONFIG_DESTDIR = pkgconfig

INSTALLS+=headers target

当我执行install时，我得到以下输出:

install -m 755 -p "/usr/lib/libproc_Model.so" "/usr/lib/libproc_Model.so"
install: `/usr/lib/libproc_Model.so' and `/usr/lib/libproc_Model.so' are the same file
make: [install_target] Error 1 (ignored)
strip --strip-unneeded "/usr/lib/libproc_Model.so"
install -m 644 -p "/usr/lib/pkgconfig/proc_Model.pc" "/usr/lib/pkgconfig/proc_Model.pc"
install: cannot stat `/usr/lib/pkgconfig/proc_Model.pc': No such file or directory
make: [install_target] Error 1 (ignored)

根据qmake源代码，您必须添加:

CONFIG += create_prl no_install_prl

create_pc仅使用命令"qmake -prl"将。pc文件目标的规则添加到makefile中，并且该命令仅在create_prl选项存在时创建。pc文件。

no_install_prl防止在${target.path}中安装由create_prl生成的不需要的.prl文件。

我在这里做了一个完整的例子:https://github.com/pvanhoof/dir-examples/blob/master/qmake-example/src/libs/qmake-example/qmake-example.pro 

## We get the PREFIX, MAJOR_VERSION, MINOR_VERSION and PATCH_VERSION
## from this project-wide include
include(../../../qmake-example.pri)
## We will use the standard lib template of qmake
TEMPLATE = lib
## We need to set VERSION to a semver.org version for compile_libtool
VERSION = $${MAJOR_VERSION}"."$${MINOR_VERSION}"."$${PATCH_VERSION}
## According https://autotools.io/libtool/version.html, section 4.3
## we should have as target-name the API version in the library's name
TARGET = qmake-example-$${MAJOR_VERSION}"."$${MINOR_VERSION}
## We will write a define in config.h for access to the semver.org
## version as a double quoted string
QMAKE_SUBSTITUTES += config.h.in
## Our example happens to use QDebug, so we need QtCore here
QT = core
## This is of course optional
CONFIG += c++14
## We will be using libtool style libraries
CONFIG += compile_libtool
CONFIG += create_libtool
## These will create a pkg-config .pc file for us
CONFIG += create_pc create_prl no_install_prl
## Project sources
SOURCES = 
    qmake-example.cpp
## Project headers
HEADERS = 
    qmake-example.h
## We will install the headers in a API specific include path
headers.path = $${PREFIX}/include/qmake-example-$${MAJOR_VERSION}"."$${MINOR_VERSION}
## Here will go all the installed headers
headers.files = $${HEADERS}
## Here we will install the library to
target.path = $${PREFIX}/lib
## This is the configuration for generating the pkg-config file
QMAKE_PKGCONFIG_NAME = $${TARGET}
QMAKE_PKGCONFIG_DESCRIPTION = An example that illustrates how to do it right with qmake
# This is our libdir
QMAKE_PKGCONFIG_LIBDIR = $$target.path
# This is where our API specific headers are
QMAKE_PKGCONFIG_INCDIR = $$headers.path
QMAKE_PKGCONFIG_DESTDIR = pkgconfig
QMAKE_PKGCONFIG_PREFIX = $${PREFIX}
QMAKE_PKGCONFIG_VERSION = $$VERSION
## Installation targets (the pkg-config seems to install automatically)
INSTALLS += headers target
