构建Qt来源与MSYS2/MinGW 64 - ICU标题找不到

Question

我遵循从MinGW-64-bit，使用选项A：构建Qt在MSYS2壳& MinGW-w64 Win64外壳的指示。

我下载的源代码

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

安装我建立OpenSSL和ICU的所有先决条件后 - 安装在

• 在/ usr /本地/ OpenSSL的
• 在/ usr /本地/ ICU

但从那里的指示并不那么清楚。据说使用Windows命令shell来设置一些环境变量。但后来我使用MSYS2 64位外壳，所以这些都没有效果。下面是我做的：

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 

配置脚本与以下停止错误：

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

在Qt的我的config.log发现：

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

为什么不呢脚本找到包含？我将它们设置为

• 参数 '-I在/ usr /本地/ ICU /包括'
• 出口INCLUDE =在/ usr /本地/ ICU /包括：在/ usr /本地/ OpenSSL的/包括

我还试图

• 参数 '-I/C/msys64的/ usr /本地/ ICU /包括'
• 出口INCLUDE =/C/msys64的/ usr /本地/ ICU /包括：/ C/msys64/usr/local/openssl/include

是否有另一种可能性给编译器提供正确的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。然后我得到以下错误：

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

所以这个时候可以找到标题！但是现在ICU库不能被链接。所以我说 '-L/C/msys64在/ usr /本地/ ICU/lib目录'，并试图再次：

../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'
