Building Qt fro Source with MSYS2 / MinGW 64 - ICU headers not found

Beitrag von irrlicht » 27. Januar 2017 16:36

I followed the instructions from https://wiki.qt.io/MinGW-64-bit [MinGW-64-bit], using Option A: build Qt in MSYS2-shell & MinGW-w64 Win64 Shell.

I downloaded the source code

Code: Alles auswählen

    git clone https://code.qt.io/qt/qt5.git
    cd qt5
    perl init-repository
    git checkout 5.8
After installing all prerequisites I build OpenSSL and ICU - installed in

- /usr/local/openssl
- /usr/local/icu

But from there on the instructions are not so clear. It's stated to use a windows command shell to set some environment variables. But later I'm using the MSYS2 64 Bit shell, so these have no effect. Here is what I did:

Code: Alles auswählen

    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
The configure script stops with the following error:
ERROR: Feature 'icu' was enabled, but the pre-condition 'libs.icu' failed.
In Qt's config.log I found:

Why doesn't the script find the includes? I set them as

- parameter '-I /usr/local/icu/include'
- export INCLUDE=/usr/local/icu/include:/usr/local/openssl/include

I also tried

- parameter '-I /C/msys64/usr/local/icu/include'
- export INCLUDE=/C/msys64/usr/local/icu/include:/C/msys64/usr/local/openssl/include

Is there another possibility to give the correct INCLUDE path to the compiler?
