Hi,
I am developing a custom map viewer using Qt, C++, QWidgets and QGIS API. I
am not trying to compile QGIS source code. I am trying to show a vector map
using Qt.
For LTR version 3.34.10
1. Installed Visual Studio 2019 community edition (Desktop Development with
C++")
2. Installed qgis-ltr-deps using OSGeo4W network installer
3. Able to include headers
4. I have included my pro file as pro1.pro
Result: Getting lots of compilation errors. I have tried with Visual studio
2019 compiler and MinGW 64 bit. Getting errors in both cases.
I have already gone through the steps available on the internet and tried
ChatGPT. Kindly help me to make a simple map viewer in windows. Thanks in
advance.
