如何使用命令行在Windows上编译qwt-6.1.2的64位库
如何使用命令行在Windows上编译qwt-6.1.2的64位库
提问于 2021-12-20 18:10:56
我们在Windows 10上使用Visual 2019、Qt5.12.3和qwt-6.1.2 (Qwt是Qt应用程序框架的图形扩展)。我们的解决方案传统上是一个32位的应用程序，但我们已经收到了以32位和64位的方式交付它的请求。
我的问题具体涉及64位qwt-6.1.2.
编译qwt-6.1.2的32位版本时，运行在批处理文件中的以下脚本没有问题(不，我们不能使用power shell，因为我们的网络上禁用了power shell脚本)。
cd\resources
tar -xf qwt-6.1.2.zip
rem del qwt-6.1.2.zip
cd\resources\qwt-6.1.2
REM Add the x86 path to compile qwt-6.1.2
SET PATH=%PATH%;C:\Qt\Qt5.12.3\5.12.3\msvc2017\bin;
REM Create qwt make files
REM 1. Set up x86 environment
"C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\VC\Auxiliary\Build\vcvars32.bat"
REM 2. Create x86 make files
qmake qwt.pro
REM 3. Compile the binaries for x86 version of qwt-6.1.2
nmake当尝试使用下面的脚本编译64位的相同源代码时，我会收到数百个链接器错误。

REM Create qwt make files
REM 1. Set up x64 environment

REM 2. Clean up the old qmake data for rebuild to x64

Stop.似乎有些地方引用了一些32位库，但我找不到任何文档(我已经搜索了几天)，这些文档专门涉及在Windows上编译64位版本的qwt-6.1.2 (或任何相关的qwt版本)。
任何关于查找64位源的指导，或关于如何为64位编译的说明都将不胜感激。

根据@SebDieBln的建议，我能够构建64位版本。不过，还需要采取一项额外步骤。
尽管我们可以运行"nmake“来清理MS构建数据，但是没有"qmake”来清理qmake数据。这是一个手动步骤。
下面是为qwt-6.1.2构建32位和64位二进制文件的完整脚本，包括中间的清理过程。
注意：这个过程不安装qwt-6.1.2，它只编译32位和64位二进制文件。
