Build and Run DLT-Viewer in debug mode. Tips?

[MaxMagazin]

Hi dlt-viewer Team,

I am experiencing a crash of the app in my macOs environment when I try to make a new ECU/TCP connection. The app starts normally though. I assume it is NOT a problem of dlt-viewer, but rather of my local environment. Cause I did have it working properly some time ago, but most probably I ruined something in my environment while installing and setting up other software packages.

Crashed Thread:        0  Dispatch queue: com.apple.main-thread

Exception Type:        EXC_BAD_ACCESS (SIGSEGV)
Exception Codes:       KERN_INVALID_ADDRESS at 0x0000000000000000
Exception Codes:       0x0000000000000001, 0x0000000000000000

Termination Reason:    Namespace SIGNAL, Code 11 Segmentation fault: 11
Terminating Process:   exc handler [2691]

How do I build and run the dlt-viewer in Debug mode to see more debug outputs, and where exactly does the app break?
So far I found a cmake flag (CMAKE_BUILD_TYPE) to build the Debug type. But can not find the cli option to start the app with debug outputs.
For building in debug mode I use: CMAKE_BUILD_TYPE=Debug Qt5_DIR="/opt/homebrew/opt/qt5" cmake "Xcode" ../ && make

The detailed macOS-Report is also attached: 2024_02_29_dlt-viewer-crash.txt

Any help will be appreciated.

are you running the ".app" or the "unix makefile"?
Which version of DLT?

Hi @bunty95,
I used the makefile to build the latest available release sources (v2.25.0), available here

[bunty95]

@MaxMagazin Use below commands, and replace the cmake portion of build.sh in the Darwin fodler.
Let me know if you have issues.

cmake -G Ninja
-DCMAKE_INSTALL_PREFIX=${INSTALL_DIR}
-DCMAKE_PREFIX_PATH=/opt/qt512/lib/cmake
-DCMAKE_BUILD_TYPE=Debug
-DDLT_USE_QT_RPATH=ON
-DDLT_PARSER=OFF
-DDLT_APP_DIR_NAME=${APP_DIR_NAME}
-DDLT_LIBRARY_INSTALLATION_PATH="${APP_DIR_NAME}/Contents/Frameworks"
-DDLT_EXECUTABLE_INSTALLATION_PATH="${APP_DIR_NAME}/Contents/MacOS"
-DDLT_RESOURCE_INSTALLATION_PATH="${APP_DIR_NAME}/Contents/Resources"
-DDLT_PLUGIN_INSTALLATION_PATH="${APP_DIR_NAME}/Contents/MacOS/plugins"
"${SRC_DIR}"
cmake --build "${BUILD_DIR}"
