Adding libudev & tinyxml libraries to my QT compiler
-
I've been searching everywhere on how to do this and kind of getting frustrated because nothing seems to work.
I am working with QT 5.5.1 on Ubuntu 16.04.5 LTS
I have downloaded tinyxml online, and installed libudev-dev from my terminal. When I try to use either of these libraries, it gives me undefined reference to 'blah blah' which are classes that are in the headerfiles. I found a lot of posts telling me to link the library to my project, but when I run something like:~projectname$ gcc -Wall -o main main.cpp -ludev, it gives me
fata error:QCoreApplication: No such file or directory. Is there a simple and effective way to link the libraries to my project?test.pro
QT += core
QT -= gui
QT += widgetsTARGET = test
CONFIG += console
CONFIG += qt
CONFIG -= app_bundleLIBS += -l/usr/lib/arm-linux-gnueabihf/libtinyxml.a
TEMPLATE = appSOURCES += main.cpp
Also, everything I change something on my .pro file, my QT compiler outputs: /usr/lib/distcc/bin/g++-5:command not found.
Then I have to go to my Makefile and change CC & CXX from /usr/lib/distcc/bin/gcc-t to just gcc-5 & g++-5 and then it works. Are there any other settings I have to change in order for my compiler to do this automatically so I don't have to keep changing this every time I try to link something.

Hi,
Are you cross-compiling your application ?
Are you building your application on an ARM machine ? -
If I may add my two cents, since you're using QtCore, why not using QXmlStreamReader? I had experience with tinyxml: the whole data is loaded (which was a problem for me) and the syntax is very close to C... This would save you from importing / compiling a new library.

Got it.
I addedCONFIG += link_pkgconfig
DEFINES += LINK_LIBUDEV
PKGCONFIG += libudevto my .pro file and it works now.
@user614 glad you found the solution. So if your issue is solved, please mark your post as such!. Thanks.
