Compilation Issues on 64 bit linux system #6

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
There are several places in the original CAIR.cpp code where a void pointer
is cast to int, which throws an error during compilation:

~/projects/seam-carving-gui$ make
g++ -c -pipe -O2 -Wall -W -D_REENTRANT -DBACKEND_CAIR -DQT_NO_DEBUG
-DQT_GUI_LIB -DQT_CORE_LIB -DQT_SHARED -I/usr/share/qt4/mkspecs/linux-g++

cair/CAIR.cpp:1264: error: cast from ‘void*’ to ‘int’ loses precision
make: *** [CAIR.o] Error 1

This was easily fixed by including the inttypes.h header and casting to
intptr_t which should be portable, as changing those 4 lines made it
compile smoothly. Thanks for the software!

I knew that crazy void*->int stuff was going to bite me sometime. I have a fix 
coming
into v2.18 of CAIR that will fix it.

:) Let me know and I'll do a Qt 4.5.1 build. Hopefully the Mac build won't suck 
as 
much then. Anybody feel like donating a Mac with OS X 10.5?

I finally got CAIR v2.18 done. Pointers are fixed. I threw in a few other 
changes
that might be of interest :)

Try the latest source package. It should work.
