c++ - 从源代码构建 Qt 5.8 - 配置 : Unknown command line option '-c++11'

Question

我按照 MinGW-64-bit 中的说明进行操作，使用选项 A:在 MSYS2-shell 和 MinGW-w64 Win64 Shell 中构建 Qt。

gcc -v 说:

Using built-in specs.

我下载了源码

git clone https://code.qt.io/qt/qt5.git
cd qt5
perl init-repository
git checkout 5.8

我知道还有其他选择:

• git 克隆 https://github.com/qt/qt5.git
• wget http://download.qt.io/official_releases/qt/5.8/5.8.0/single/qt-everywhere-opensource-src-5.8.0.tar.gz

我在第二个选项(存档)中发现了同样的问题。

安装所有先决条件后，我构建 OpenSSL 和 ICU - 安装在

• /usr/local/openssl
• /usr/local/icu

但是从那里开始的说明不是很清楚。据说使用 windows 命令 shell 来设置一些环境变量。但是后来我使用的是 MSYS2 64 位 shell，所以这些都没有作用。这是我所做的:

export INCLUDE=/usr/local/icu/include:/usr/local/openssl/include
export LIB=/usr/local/icu/lib:/usr/local/openssl/lib
export QMAKESPEC=
export QTDIR=
windows2unix() { local pathPcs=() split pathTmp IFS=\;; read -ra split <<< "$*"; for pathTmp in "${split[@],}"; do pathPcs+=( "/${pathTmp//+([:\\])//}" ); done; echo "${pathPcs[*]}"; }; systemrootP=$(windows2unix "$SYSTEMROOT"); export PATH="$PWD/qtbase/bin:$PWD/gnuwin32/bin:/c/msys64/mingw64/bin:/c/msys64/usr/bin:/c/msys64/usr/local/icu/lib"
export MAKE_COMMAND=
./configure -debug-and-release -opensource -confirm-license -platform win32-g++ -developer-build -c++11 -icu -opengl desktop -openssl -plugin-sql-odbc -nomake examples -nomake tests

配置脚本运行了一段时间，但随后因以下错误而停止:

...
Creating qmake................................................................................................Done.
Info: creating stash file C:\msys64\home\asp\qt5\.qmake.stash
Info: creating super cache file C:\msys64\home\asp\qt5\.qmake.super
ERROR: Unknown command line option '-c++11'.

也许我忘记在某处设置一些标志，但目前我被困在这里。有人知道如何继续吗？

根据 Andrei R. 的评论，我删除了标志 -c++11 并且这个接缝可以解决问题。
