Just tried it. Unfortunately, it doesn't work:
bc++ -v -q -ebin/kylix/debug/main-target-hello/hello 
bin/kylix/debug/main-target-hello/main.o
bin/kylix/debug/main-target-hello/hello_world_widget.o
bin/kylix/debug/main-target-hello/moc_hello_world_widget.o 

Error: Unresolved external 'QApplication::~QApplication()' referenced from 
bin/kylix/debug/main-target-hello/main.o

Obviously, the linker command line is incomplete: the -L option and the QT 
library are missing. Here is something that works:
bc++ -v -q -L$QTDIR/lib -ebin/kylix/debug/main-target-hello/hello 
bin/kylix/debug/main-target-hello/main.o 
bin/kylix/debug/main-target-hello/hello_world_widget.o
bin/kylix/debug/main-target-hello/moc_hello_world_widget.o 
libqt.so

As you see, I didn't use "-lqt" because that doesn't work. According to the 
bc++ documentation, "-l" does something else:
-lx Pass option x to linker
-l-x Disable option x for linker
So, I don't know if there's a better way to specify libraries. Makefiles 
generated by the Kylix IDE actually contain calls to ilink where the 
libraries are also specified by their complete file name. As a reminder, 
here's an excerpt from a Kylix generated Makefile that I send to you in a 
previous email:
ilink \ 
-Tpd -aa -D"" -x -Gn -v \
-Ltmp:/Net/hubble/Users/felix/local/lib/kylix3//lib/obj \
-L/Net/hubble/Users/felix/local/lib/kylix3//lib:/usr/lib:/lib \
-L/usr/X11R6/lib:/Net/hubble/Users/felix/local/lib/kylix3//bin \
borinitso.o foo.o, libfoo.so,, \
libborcrtl.so libborstl.so libborunwind.so libc.so libm.so libdl.so,, \
foo.res
