help about linking a library

[RajasekharReddy Guntaka]

Hi group,
When I compile an GUI program with gcc, command gives ld exit status.

I compiled a program with fallowing command.
gcc -I/usr/local/include -I/usr/openwin/include -I/homes/guntaka/pub/guide/include -DMAIN -D_OTHER_TEXTSW_FUNCTIONS -DHARDWIRED -g -L/usr/local/lib -L/usr/openwin/lib -L/homes/guntaka/pub/guide/lib -o dlx_hw dlx_ui.o hw_ui.o dlx_stubs.o dlx_paint.o dlxasm.o dlx_mem.o dlx_simu.o datapath.o dp_op.o hw_ed_op.o hw_init.o hw_cu.o hw_file.o hw_paint.o -lguide -lguidexv -lxview -lolgx -lX11 -lpixrect

I put guide and guidexv in /homes/guntaka/pub/guide

the command gives th fallowing error.
cannot find -lpixrectld returned 1 exit status.

but i am sure that pixrect header files is in /usr/openwin/include
I think I have to create some library file like libpixrect.a
Is it in system library default.
Or how can I create that library file

please help me.



sincerely,

This is irrelevant - the linker returned an error stating it can't
find a library file (not header file).

Are you sure you need that library? Try to compile without the
-lpixrect switch. You can create that file by compiling the software
this library belongs to or you possibly find an already compiled
version for your architecture and OS. Just search the web - google is
your friend.
