Issue with Log4Qt in Cross-Compilation Setup for BeagleBone Black

seqat

Hello Qt Community, I’m currently working on a project where I’m cross-compiling Qt applications for a BeagleBone Black (BBB) using Ubuntu 20.04. I’ve integrated Log4Qt into my project but encountered some issues during the cross-compilation process. I’m new to the Qt platform so I might be missing something fundamental.

Here’s a brief overview of my setup:

Qt Version: 5.15.2
Cross-Compiler: GCC Linaro 7.5.0 (using their sysroot 2.25, all folders in the home directory)
Target Platform: BeagleBone Black (BBB)
Operating System: Ubuntu 20.04

Problem:
When I try to build my project with Log4Qt, I get an error like this:

/home/userProfile/qt-everywhere-src-5.15.2/Log4Qt/src/log4qt/helpers/initialisationhelper.h:24: error: log4qt/log4qtdefs.h: No such file or directory

I’ve verified that Log4Qt is correctly configured and the necessary libraries are present, but I’m still facing problems.

What I’ve Tried:

Cleaned and rebuilt the project
Tried static linking
Updated the project’s .pro file with the following changes:


include(/home/userProfile/qt-everywhere-src-5.15.2/Log4Qt/src/log4qt/log4qt.pri)

QT += network core
QT += sql concurrent

INCLUDEPATH += /include
LIBS += -L/usr/lib -llog4qt

# Default rules for deployment.
qnx: target.path = /tmp/$${TARGET}/bin
else: unix:!android: target.path = /opt/$${TARGET}/bin
!isEmpty(target.path): INSTALLS += target

HEADERS += \
    mqttloggerbridge.h \
    loggermodule.h

SOURCES += \
        loggermodule.cpp \
        mqttloggerbridge.cpp \
        main.cpp

I would greatly appreciate any guidance or suggestions on how to resolve this issue. If additional information is needed, please let me know.

Thank you in advance for your help!

Best regards,

I solved the issue by changing INCLUDEPATH += /include to INCLUDEPATH += /absolute/path/of/include for both INCLUDEPATH and LIBS.
