hi all i compile qt embedded 4.6.2 successfully and when i want copy lib directory to my sdcard i have this error : Error while copying "libQtCore.so", There was an error copying the file into /media/5EEB-D89E/usr/local/Qt/lib. Filesystem does not support symbolic links how can i copy all of this file to sdcard? thanks a lot. i m use ubuntu 10.04
write on commandline of mini2440: export $LD_LIBRARY_PATH = /my/lib/path under /my/lib/path must be all Qt libs which your app use
thank you i copy my files with filezilla and my problem solved but when i run some demos in mini2440 i get illegal instruction error. what am i doing? whats the problem
illegal instruction comes if you dont compile with arm-linux-g++ maybe you compile for x86? also for your desktoplinux
Ok how can i compile with arm-linux-g++? another question when i configure qt 4.6.2 i dont use -nomouse-tslib because i m getting error of that -although my ubuntu have tslib library- so i want use qtopia ts lib but my directory isn't like the directory of another this is my directorys in mini2440: but i have this directory with this files: /usr: bin , local, sbin , share /usr/local: bin , etc, lib /usr/local/bin: ts_calibrate (file) /usr/local/etc: ts.conf (file) /usr/local/lib/ts: dejitter.so, input.so, linear.so ,pthres.so ,variance.so how i must set environmental variables of mini2440? thanks a lot.
to compile with arm-linux-g++ , you have to change mkspecs/qws/linux-arm-g++/qmake file, also actually there is already setted as arm-linux-g++, but everybody prefers to use arm-none-linux-gnueabi-g++. I dont know the difference, but i compiled yesterday with arm-linux-g++ and i have segmentation fault. I have now problems with tslib, because i cant compile tslib with arm-none-linux-gnueabi you have to add on your PATH something like /usr/local/arm/4.3.2/bin, or where ever you installed your compiler.
ok so you mean i dont need set environmental variable for tslib and only i must set another environmental variables,is this correct? and about compiling with arm-linux-g++, i install qt sdk on my ubuntu before, and i use Qt creator for create application. so i must change Makefile, what i must change in my MakeFile? thanks.
ok i compile with arm-linux-g++ and arm-none-linux-gnueabi-g++ in both release and debug mode successfully but when i run program on board i get illustration error again. what am i doing? whats wrong? i get a headache! please help me.
i mean illegal instruction error again and again
hey danics, try this steps: http://projektender.blogspot.com/ its worked with my mini2440
thanks Andreo for your helps but before i test this please tell me how you copy library files to your mini2440, maybe i m wrong with that,some file in this directory is link file so i cant use cp command for copy their to my flash or SD card and i get this error: Fat32 dont support this kind of file, but when i m using filezilla i can copy them to SD card, so what are you doing?
something strange happened. i cant compile anymore my qt 4.6 i get this error in every condition for qws/arm-linux-g++/qmake file,( i test all compile type ) when configuration is complete and i want to make i get this error: bootstap -lbootstrap -lz error /usr/bin/ld havent -lz, i don't know what is change,but i don't get this error before. i m so tired, what am i doing now?
I also ran into problems some time ago when compiling QT with gcc 4 without deactivating optimization (thus the -O0 suggestion in one of the previous messages). I'm wandering if using gcc 3 instead avoids this problem (and if it's possible and how, since I couldn't get it, even through crosstool), since I've noticed gcc optimizer seems to have lots of issues in cross-compilers (I've banged my head against the wall with avr-gcc v4, and had to revert to v3 for getting rid of them). Best regards
