help on getting ezx working..

[mightymop]

hello guys
i have a working cross compiler and now want to set it up for compiling ezx applications for my a780
then i installed the ezx_sdk from forum...
now everytime i wanted to compile a hello word included in the sdk i got compile errors from the QT libs (something is not declared and others)
i copied the header files in all include directories that have sth. to do with the cross toolchain and sdk to eliminate patherrors.. but no luck

i have opensuse 10 running and also tried ELDK but this doesn't work
so i use the ezx-crosstool-0.5

could someone give some instructions how to set up my environment?

ps: i also have searched the forum

i did use the standard installation directories (/opt) for the cross-compiler and ezx-sdk...

Maybe I can help you with my ezx text editor source code. I will attach it in development forum, be patient. I have build native ezx text editor base on ezx-crosstool-0.5 and dev-ezx-0.2.0 + zmultilineedit header from ezx_sdk.

i am using dev-ezx-0.2.0 too and always get the following errors when i try to compile the helloworld program

mopserver:/opt/dev-ezx-0.2.0/helloworld # make
arm-linux-g++ helloworld.o -o helloworld -L../lib -L../lib/ezx/lib -lezxappbase-xscale-r -lqte-mt-xscale-r -lezxjpeg-xscale-r -lezxnotification-xscale-r
/opt/crosstool/gcc-arm-iwmmxt/gcc-3.3.6-glibc-2.3.2/arm-linux/lib/gcc-lib/arm-linux/3.3.6/../../../../arm-linux/bin/ld: cannot find -lqte-mt-xscale-r
collect2: ld returned 1 exit status
make: *** [helloworld] Error 1

of course I copied the libraries from phone to /opt/dev-ezx-0.2.0/lib and /opt/dev-ezx-0.2.0/lib/ezx/lib

[blackhawk]

Try my addon package to dev-ezx-0.2.0. Good luck!

[mightymop]

i copied your addon to /opt/dev-ezx-0.2.0/ and extracted it like decribed
then i switched to /opt/dev-ezx-0.2.0/helloworld-qmake and have edit
the setenv.sh, did a qmake helloworld.pro, make ...
and now i get this:

mopserver:/opt/dev-ezx-0.2.0/helloworld-qmake # qmake helloworld.pro
mopserver:/opt/dev-ezx-0.2.0/helloworld-qmake # make
/opt/dev-ezx-0.2.0/helloworld-qmake/../qt/bin/moc -I../qt/mkspecs/qws/linux-ipaq-g++ -I. -I/opt/dev-ezx-0.2.0/helloworld-qmake/../qt/include -I/opt/dev-ezx-0.2.0/helloworld-qmake/../ezx/include -I. -I. helloworld.cpp -o helloworld.moc

i think a little step by step documenation after installing the crosstool would be very useful

I have follow leprechaun's and samr7's crosstool build instructions on Fedora Core 3 (qt-3.3.2) and then read carefully dev-ezx build instructions. samr7's crosstool resolve calculation problem (i.e. opie calculator, I call opie 'strange' calculator before recompile it with samr7's crosstool), now I used samr7's solution.

I am not an advance to prepare a Makefile, I need qmake of course. Read my output message to build samr7's helloword, is there something different? Please check your qmake version.

[rpconnect]

that sounds like the problem. have you checked to make sure that the reported "missing" library is actually in "-L/opt/dev-ezx-0.2.0/helloworld-qmake/../ezx/lib"? (i noticed in a previous post that you said you did copy these over, but for some reason its still not seeing this lib).

[mightymop]

yes i now have copied them again to this folder
and furthermore some copies named ezxappbase-xscale-r, ezxappbase-xscale-r.so.1.0.0, libezxappbase-xscale-r,... but still the same error...
i try to compile with root permission so he should be able to read all directories...

hm.. !?!?

UPDATE:
i've found the error i had renamed all Libs to lib*.so without the version number at the and this results in another error, but the linker could now find the libs
new ERROR:

arm-linux-g++ -Wl,-rpath-link,/opt/crosstool/gcc-arm-iwmmxt/gcc-3.3.6-glibc-2.3.2/arm-linux/arm-linux/lib -o helloworld helloworld.o -L/opt/dev-ezx-0.2.0/helloworld-qmake/../qt/lib -L/opt/dev-ezx-0.2.0/lib -lezxappbase-xscale-r -lezxjpeg-xscale-r -lezxnotification-xscale-r -lpthread -lqte-mt-xscale-r

make: *** [helloworld] Error 1

[mightymop]

yeah i get it

the last error comes up 'cause i file was corrupted...

now it works, i can compile ezx

thank u all

PS: any good ideas for some usefull applications? hehe
