Question

我按照MinGW-64-bit的说明，使用选项A：在MSYS2-shell＆amp;中构建Qt。 MinGW-w64 Win64 Shell。

我下载了源代码

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

安装所有先决条件后，我构建了OpenSSL和ICU - 安装在

中

的/ usr /本地/ OpenSSL的
的/ usr /本地/ ICU

但从那里开始，指示并不那么明确。它声明使用windows命令shell来设置一些环境变量。但后来我使用的是MSYS2 64 Bit shell，所以这些都没有效果。这是我做的：

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=

mkdir qt-build
cd qt-build

../qt5/configure -prefix /opt/qt -debug-and-release -opensource -confirm-license -platform win32-g++ -developer-build -icu -I /usr/local/icu/include -opengl desktop -openssl -plugin-sql-odbc -nomake examples -nomake tests

configure脚本因以下错误而停止：

ERROR: Feature 'icu' was enabled, but the pre-condition 'libs.icu' failed.

在Qt的config.log中，我发现：

Trying source 0 (type inline) of library icu ...
 => source failed condition 'config.win32 && !features.shared'.

为什么脚本找不到包含？我将它们设置为

参数＆＃39; -I / usr / local / icu / include＆＃39;
export INCLUDE = / usr / local / icu / include：/ usr / local / openssl / include

我也试过

参数＆＃39; -I / C / msys64 / usr / local / icu / include＆＃39;
export INCLUDE = / C / msys64 / usr / local / icu / include：/ C / msys64 / usr / local / openssl / include

是否有另一种可能性为编译器提供正确的INCLUDE路径？

最后我解决了这个问题！

我删除了完整的qt5文件夹并从头开始。然后我收到以下错误：

Trying source 0 (type inline) of library icu ...
  => source failed condition 'config.win32 && !features.shared'.
Trying source 1 (type inline) of library icu ...

这次可以找到标题！但现在ICU lib无法链接。所以我添加了'-L / C / msys64 / usr / local / icu / lib'并再次尝试：

../qt5/configure -prefix /opt/qt -debug-and-release -opensource -confirm-license -platform win32-g++ -developer-build -icu -I /C/msys64/usr/local/icu/include -L /C/msys64/usr/local/icu/lib -opengl desktop -openssl -plugin-sql-odbc -nomake examples -nomake tests

Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into 'C:\msys64\opt\qt'

使用MSYS2 / MinGW 64构建Qt源 - 未找到ICU标头
