Library Issues (SDL)
-
I'm about ready to tear my hair out. I'm not used to using Qt, and I'm using a privately developed SDK for programming a Multitouch device. I transferred my code from an old computer to a new one running Lion, and while it worked in Snow Leopard and the environment I configured there, it's now throwing up errors over the stupidest things.
So, my issue. I'm not familiar with the .pro file, and I will not pretend to being comfortable with its set up. Here are the contents of the file:
@SOURCES += Main.cpp
tilewidget.cpp
activewidget.cpp
scorewidget.cpp
tilehome.cppCONFIG -= qt
TARGET = HelloWorld
macx {
LIBS += -framework Nimble
LIBS += -framework Radiant -framework Luminous -framework Screenplay
LIBS += -framework MultiTouch -framework MultiWidgets
LIBS += -framework Valuable -framework Fluffy -framework Poetic
LIBS += -lSDL -lSDLmainLIBS += -framework Cocoa
}HEADERS +=
tilewidget.hpp
activewidget.hpp
scorewidget.hpp
tilehome.hpp@When I try to compile the code, I get the following error from the compiler.
@09:49:00: Running build steps for project HelloWorldExt...

Hi Hostel,
Thank you for your response! I did try to do something like that, but it then freaked out about other things. It turns out the darn developers for the SDK didn't tell me they moved things around in their latest release, so I had to adjust my qmake steps. ARGH! Thank you so much for your help!

Hi Hostel,
It was for the Cornerstone SDK; I had been using 1.1.2, and upgraded to 1.2.0. The changes I needed to make were to add the following lines to my .pro file:
@INCLUDEPATH += /opt/multitouch/include
QMAKE_LIBDIR += /opt/multitouch/lib@After that, everything worked beautifully. :)
