Use of own C functions with Qt projects

[Fabrizio Santini]

Hi,
I need to use some my C function in a Qt project.
But when I try to include and build them, the compiler
answers:

gcc -DHAVE_CONFIG_H -I. -I. -I.. -I/usr/lib/qt/include
-I/usr/X11R6/include     -O0 -g3 -Wall    -c plates.c
/bin/sh ../libtool --mode=link g++  -O0 -g3 -Wall      -o plates4linux
-L/usr/X11R6/lib   plates.o neural.o imageproc.o debug.o
plates4linuxview.o plates4linux.o main.o plates4linuxview.moc.o
plates4linux.moc.o  -lqt -lXext -lX11  
g++ -O0 -g3 -Wall -o plates4linux plates.o neural.o imageproc.o debug.o
plates4linuxview.o plates4linux.o main.o plates4linuxview.moc.o
plates4linux.moc.o  -L/usr/X11R6/lib -lqt -lXext -lX11
plates4linux.o: In function `Plates4Linux::_RunPlatesRecognition(void)':
/home/fabrizio/projects/plates4linux/plates4linux/plates4linux.cpp:340:
undefined reference to `B(void)'
/home/fabrizio/projects/plates4linux/plates4linux/plates4linux.cpp:340:
undefined reference to `B(void)'
collect2: ld returned 1 exit status
make: *** [plates4linux] Error 1
*** failed ***

where B is the C function declared in a <file>.c with <header>.h as

int B(void);

Can you help me?
