Title: Can\'t link Qt Hello World on Dev image on C860
Post by: d_aero on June 02, 2004, 06:43:42 pm

I have loaded the 1.5 dev img and somehow copied the devkit on to my internal memory. (I am a Zaurus newbie but not a Unix novice so I understand normal mounts but not image mounting !)

I can get the obligatory Hello World to compile but when I link i get :-

/tmp/cc5jqItG.o(.rodata+0xe4): undefined reference to `QDropEvent type_info node\'
/tmp/cc5jqItG.o: In function `QArray<char> type_info function\':

The compilation command I am using is:

g++ -o hello hello.cpp -I /home/zaurus/devkit/include -I /home/zaurus/devkit/include/qt -lqte -L  /home/zaurus/devkit/lib

Can anybody help please ?

Also can anybody point me to a good explanation of how image mounting works on Zaurus ?

Don\'t compile by hand, use qmake.

As for your specific error, supply -fno-rtti to the compiler since your qte library also is compiled without RTTI.

Thanks Mickeyl, that got me further. I found a post with the full g++ command so I also added those options but I am still getting link errors:

/home/zaurus/devkit/lib/libmng.a(libmng_cms.o): In function `mnglcms_initlibrary\':
libmng_cms.o(.text+0x10)undefined reference to `cmsErrorAction\'
cmsOpenProfileFromFile, cmsOpenProfileFromMenu etc.........

Any clues ?.

I would use qmake but it doesn\'t appear to be in the dev-img. Is there somewhere I can get this from. I have used it successfully on the Linux box.

Any help welcome, I would love to get this going on the Z itself.
