android - Qt 为所有架构构建静态库

问题描述

我尝试为 Android (*.a) 构建静态库。我的简历：

QT -= gui

TEMPLATE = lib
CONFIG += staticlib

CONFIG += c++11

DEFINES += QT_DEPRECATED_WARNINGS

ANDROID_ABIS = armeabi-v7a arm64-v8a x86 x86_64

SOURCES += \
    untitled3.cpp

HEADERS += \
    untitled3.h

文件 untitled3.cpp 和 untitled3.h 很简单。当我构建项目时，我得到了唯一的一个库 *.a，但预计会为所有架构获得四个库：armeabi-v7a arm64-v8a x86 x86_64

当我第一次构建时，编译完成时出现错误：

当我第二次构建时，编译成功完成，但在输出目录中我找到了一个 *.a - lib： 6543a40d-136b-42c6-a0c4-8a8c3f2b59ab-image.png

在文件夹 armeabi-v7a arm64-v8a x86 x86_64 仅存在 *.obj - 文件，但不存在。a - 文件。我的问题：为所有（4）架构的android构建静态库（ .a）如何正确？PS：Qt安卓版：5.14.1；Qt Creator 版本：4.11.0，基于 Qt 版本：5.14.0

解决方案

您是否尝试过为每个 android 架构（每个架构一个 .pro）构建 4 个单独的项目，看看结果是什么？当项目变得更大时，这显然并不理想，但从诊断的角度来看，值得一试。
