Bug ID: 405661
Summary: Cross-mingw64 compilation: Cannot compile app using
syntax highlighting framework
Product: frameworks-syntax-highlighting
Version: 5.56.0
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: framework
Assignee: kwrite-bugs-n...@kde.org
Reporter: mar...@rpdev.net
Target Milestone: ---
SUMMARY
In a Fedora mingw64 cross compile environment for Windows, in an app using the
syntax highlighting framework, compilation fails with the following error:
In file included from
/usr/i686-w64-mingw32/sys-root/mingw/include/c++/ext/string_conversions.h:41,
from
/usr/i686-w64-mingw32/sys-root/mingw/include/c++/bits/basic_string.h:6400,

^~~~~~~~~~
STEPS TO REPRODUCE
1. Set up mingw64 cross compile environment in Fedora by installing from
repository.
2. Install ECM and syntax-highlighting framework from source.
3. Try to compile an app which uses cmake and which compiles and links against
the syntax highlighting library.
OBSERVED RESULT
Compilation fails (e.g. when #include <functional> is used).
EXPECTED RESULT
Compilation works fine.

ADDITIONAL INFORMATION
I am developing an app which I also want to compile for Windows. For this
purpose, I am using the mingw64 packages provided by Fedora. Qt 5 is provided
as part of these packages as well. I am using Docker for this. To reproduce,
you can create a Docker image using the following Dockerfile:
=====================================

dnf install -y --nogpgcheck \
cmake \

cd / && \
git clone https://github.com/qt/qtquickcontrols2.git && \
cd qtquickcontrols2 && \
git checkout v$(mingw32-qmake-qt5 -query QT_VERSION) && \
mingw32-qmake-qt5 && \
make -j4 && \
make install && \
cd .. && \
rm -rf qtquickcontrols2
=====================================
In my app, I also want to use the syntax highlighting framework. As this
library is not part of the mingw packages included in Fedora, I compile and
install both ECM and the syntax highlighting framework as part of my build
script:
# Install ECM
pushd 3rdparty/KDE/extra-cmake-modules
mkdir -p build
cd build
mingw32-cmake -GNinja ..
cmake --build .
cmake --build . --target install
popd
# Install KDE syntax highlighting
pushd 3rdparty/KDE/syntax-highlighting
mkdir -p build
cd build
mingw32-cmake -GNinja -DKF5_HOST_TOOLING=/usr ..
cmake --build .
cmake --build . --target install
popd
After this is done, I try to compile my own app, which, among other things,
does the following to include the syntax highlighting library:
# Find KDE Syntax Highlighting engine
find_package(KF5SyntaxHighlighting)
if(KF5SyntaxHighlighting_FOUND)
set(LIB_LIBRARIES ${LIB_LIBRARIES} KF5::SyntaxHighlighting)
set(LIB_DEFINES ${LIB_DEFINES} HAVE_KF5_SYNTAX_HIGHLIGHTING)
endif()
The two variables LIB_LIBRARIES and LIB_DEFINES are used later on to set linker
and compiler flags for the app. When trying to build, however, the compilation
fails e.g. when using
#include <functional>
When I edit the file
/usr/i686-w64-mingw32/sys-root/mingw/lib/cmake/KF5SyntaxHighlighting/KF5SyntaxHighlightingTargets.cmake
and change the following:
set_target_properties(KF5::SyntaxHighlighting PROPERTIES
INTERFACE_INCLUDE_DIRECTORIES
"/usr/i686-w64-mingw32/sys-root/mingw/include/KF5/KSyntaxHighlighting;/usr/i686-w64-mingw32/sys-root/mingw/include/KF5;/usr/i686-w64-mingw32/sys-root/mingw/include"
INTERFACE_LINK_LIBRARIES "Qt5::Gui"
)
to:
set_target_properties(KF5::SyntaxHighlighting PROPERTIES
INTERFACE_INCLUDE_DIRECTORIES
"/usr/i686-w64-mingw32/sys-root/mingw/include/KF5/KSyntaxHighlighting;/usr/i686-w64-mingw32/sys-root/mingw/include/KF5"
INTERFACE_LINK_LIBRARIES "Qt5::Gui"
)
Then compilation works fine. I am not entirely sure, but it seems that this
might be due to the include directories set there are passed to consuming
targets via the `-isystem` switch.
