Question

我正在创建一个使用外部库的小型Qt应用程序。我有头文件和lib文件。我的专业档案是

QT       += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = IndexCreator
TEMPLATE = app


SOURCES += main.cpp\
        mainwindow.cpp

HEADERS  += mainwindow.h


win32:CONFIG(release, debug|release): LIBS += -L$$PWD/../ExternalLibrary/ -lHASHLIB
else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/../ExternalLibrary/ -lHASHLIBd

INCLUDEPATH += $$PWD/../ExternalLibrary
DEPENDPATH += $$PWD/../ExternalLibrary

我收到了这个错误：

12:01:11: Running steps for project IndexCreator...

我需要使用此库中的函数。

似乎你正在混合mingw（你的工具链设置）和msvc（如何构建hashlib）。如果可能的话，在Windows上甚至是最新版本都应该以几乎所有成本避免这种情况。

由于您似乎无法访问源代码，如果您无法让供应商提供mingw版本，您最好删除项目的mingw，或者将hashlib作为依赖项。

在Qt中添加外部库时出错“文件格式无法识别”
