nano-x user program

Hi,

finally I created user/displaytext and added it in menuconfig, i run compiler in this directory:

/>nios2-linux-uclibc-gcc displaytext.c -o displaytext -I/home/uclinux/nios2-linux/uClinux-dist/user/microwin/src/include -L/home/uclinux/nios2-linux/uClinux-dist/user/microwin/src/lib -lnano-X -lpthread

and it compiled okay to file for running

*displaytext

but when i run in altera nios ii embedded evaluation kit (http://www.terasic.com.tw/cgi-bin/page/archive.pl?language=english&categoryno=56&no=372) after

/>nano-X &

/>nanowm &

/>displaytext &

it made crash system - uclinux finished and i am back from nios-terminal.

When i see to make process, i see that make run nios2-linux-uclibc-gcc .....with -lmwengine -lmwdrivers -lmwfonts -ljpeg -lpthread -lm -lz

and when i try:

/>nios2-linux-uclibc-gcc displaytext.c -o displaytext -I/home/uclinux/nios2-linux/uClinux-dist/user/microwin/src/include -L/home/uclinux/nios2-linux/uClinux-dist/user/microwin/src/lib -lmwengine -lmwdrivers -lmwfonts -lphtread -lm -lz

It reports:

/home/uclinux/nios2-linux/toolchain-build/build/nios2/lib/gcc/nios2-linux-uclibc/3.4.6/../../../../nios2-linux-uclibc/bin/ld.real: cannot find -lphtread

collect2: ld returned 1 exit status

Now i am not able to continue. I tryed to make all again with this error.

I compiled user/microwin/demos first time only random way, i think.

Maybe i with make clean and make erase something important.

I can try again install uclinux and compile again.

I wanted only use nano-x with nxview example.jpg

and after this draw and erase some lines in real time.....

Is any other way to draw/erase lines except use nano-x (lib) ?

Thank you.

Jan

drunken79 (http://forum.niosforum.com/forum/index.php?showuser=6042) posted SDL sources at sdl for nios2 (http://drunken.inter****.com/sdl.tar.gz)

look in the file CONFIGURE.NIOS for ./configure options. After compiling, the library is in /src/.libs/ or in the directory you specified with --prefix.

Some small example programms from :
