Bug ID: 474749
Summary: KDevelop crashes when adding wxWidgets
Classification: Applications
Product: kdevelop
Version: 5.12.230801
Platform: Other
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: Language Support: CPP (Clang-based)
Assignee: kdevelop-bugs-n...@kde.org
Reporter: cabral....@gmail.com
Target Milestone: ---
Created attachment 161765
--> https://bugs.kde.org/attachment.cgi?id=161765&action=edit
main.cpp with #include wx.h and CMakeLists.txt with wxWidgets package
configured
Have wxWidgets installed.
```
$ wx-config --cxxflags --libs
-I/usr/lib/wx/include/gtk3-unicode-3.2 -I/usr/include/wx-3.2 -DWXUSINGDLL
-D__WXGTK3__ -D__WXGTK__ -pthread
-pthread -lwx_gtk3u_xrc-3.2 -lwx_gtk3u_html-3.2 -lwx_gtk3u_qa-3.2
-lwx_gtk3u_core-3.2 -lwx_baseu_xml-3.2 -lwx_baseu_net-3.2 -lwx_baseu-3.2
```
Create a new project from template "Terminal" (hello world with cmake).
Add to main.cpp the widgets header
```
#include <wx/wx.h>
```
Add wxWidgets package to the CMakeLists.txt
```
find_package(wxWidgets REQUIRED)
include(${wxWidgets_USE_FILE})
```
Saving CMakeLists.txt trigger KDevelop to start cmake reconfiguration and
during the "Background parser", KDevelop crashes.
If one removes the `#include`, the reconfiguration does not crash, but adding
it back and reconfiguring will crash.
If one has the `#include`, but not the `find_package()` and reconfigures,
KDevelop does not crash.
Only when both are present is that KDevelop crashes, and only during
auto-reconfigure (the crash happens during the "Background parser").
It also crashes if the CMakeLists.txt uses `wx-config`, but as before, only if
there is `#include` in the code.
```
# wx-config-qt or wx-config

message("wx_CFLAGS ${wx_CFLAGS}")
# wx-config-qt or wx-config

```
Tested on Ubuntu and Biglinux (Manjaro).
Tested with wxWidgets-qt and wxWidgets-gtk3.
```
$ wx-config-qt --cxxflags --libs
-I/usr/lib/wx/include/qt-unicode-3.2 -I/usr/include/wx-3.2 -DWXUSINGDLL

-pthread -lwx_qtu_xrc-3.2 -lwx_qtu_html-3.2 -lwx_qtu_qa-3.2 -lwx_qtu_core-3.2
-lwx_baseu_xml-3.2 -lwx_baseu_net-3.2 -lwx_baseu-3.2
```
Building from the command line it compiles fine.
