如何從 Windows 10 上的源代碼構建 Qt 6.2.2

Question

我一直在嘗試從源代碼構建 Qt 6.2.2。 我從在線安裝程序下載了 package 源代碼，但每次都失敗，每次都出現不同的錯誤。 我嘗試了各種配置，例如：

configure.bat -static -release -platform win32-msvc -opensource -confirm-license -prefix "C:\Qt\6.2.2\Static" -make libs -make tools -nomake examples -nomake tests

configure.bat -static -release -platform win32-msvc -opensource -confirm-license -prefix "C:\Qt\6.2.2\Static" -make libs -make tools -nomake examples -nomake tests -no-icu -no-opengl -no-openssl -skip qtwayland -skip qtquick3d -skip qtquickcontrols2 -skip qtquicktimeline -skip qtshadertools -skip qtdeclarative -skip qtdoc -skip qttranslations -skip qt3d -skip qt5compat -skip qtcharts -skip qtcoap -skip qtdatavis3d -skip qtlottie -skip qtmqtt -skip qtopcua -skip qtscxml -skip qtvirtualkeyboard -skip qtmultimedia -skip qtwebengine -skip qtwebview

configure.bat -static -release -platform win32-msvc -opensource -confirm-license -prefix "C:\Qt\6.2.2\Static" -no-openssl -make libs -make tools -nomake examples -nomake tests

我嘗試使用 VS 2017 的 x86_x64 交叉工具命令提示符、VS 2019 的 x86_x64 交叉工具命令提示符和 VS 2019 的 x64 本機工具命令提示符

這是我使用所有配置選項時遇到的錯誤之一，然后cmake --build.

我還從這里下載了 5.15.x 源代碼，我可以使用我發布的第一個配置命令毫無問題地構建它。

我目前有草莓 Perl 5.32.x、python 3.10、3.9.x 和 Cmake 3.22.1 它們都安裝在我的路徑中據此，我符合要求。 我確認使用 where <insert_name.exe> 返回的路徑是正確的：

where perl.exe
C:\Strawberry\perl\bin\perl.exe
where python.exe
C:\Users\MyNAme\AppData\Local\Programs\Python\Python39\python.exe
C:\Users\MyName\AppData\Local\Programs\Python\Python310\python.exe
where cmake.exe 
C:\Program Files\CMake\bin\cmake.exe
C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\Common7\IDE\CommonExtensions\Microsoft\CMake\CMake\bin\cmake.exe

當我寫這篇文章時，我一直在挖掘並發現了大量關於同一問題的錯誤報告。 似乎都回到了 OpenSSL。 我抓住了 OpenSSL 源，我安裝了 NASM 並將其添加到我的路徑中。 我配置並構建了 OpenSSL ：

perl Configure VC-WIN64A
nmake all

一旦 OpenSSL 完成重新配置 Qt ：

configure.bat -prefix "C:\Libraries\QT-Static" -release -platform win32-msvc -opensource -confirm-license -make libs -make tools -nomake examples -nomake tests -I "C:\Program Files\OpenSSL\include\openssl" -L "C:\Program Files\OpenSSL\lib"

這次它顯示以下內容：

Qt Network:
getifaddrs() ........................... no
IPv6 ifname ............................ no
libproxy ............................... no
Schannel ............................... yes
OpenSSL ................................ yes
Qt directly linked to OpenSSL ........ no
OpenSSL 1.1 ............................ yes
DTLS ................................... yes
OCSP-stapling .......................... yes
SCTP ................................... no
Use system proxies ..................... yes
GSSAPI ................................. no
Brotli Decompression Support ........... no

然后跑：

cmake --build . --parallel

它仍然失敗，但這次出現了更多錯誤，再次鏈接回 OpenSSL 問題。 我想這可能與 CMAKE_CXX_STANDARD 標志有關，所以我強制 17 而不是讓 MSVC 強制最新但沒有運氣。 有沒有人設法讓 6.2.2 在 windows 10 上構建，如果是這樣怎么辦？

將編譯器升級到最新的 VS2019 版本 (16.11) - 另請參閱https://bugreports.qt.io/browse/QTBUG-97999
