/home/vivien/Desktop/openocdcopie/src/helper/options.c:130:
undefined reference to `usbinit'
This is a linking problem. Compiled code references a symbol that is not
present when linking. (What would happen if you forget to link in an .o
file for instance.).
Automake, autoconf etc. can sometimes be a bit tricky.
Yes :(
But in general they
end up wrapping gcc.
What I would do.
Which .c file is "usbinit" defined in.
usbinit is a function in detection.c called on options.c
Is that .c file compiled to an .o file? (You can always try to add
#error Some dummy text
into the .c file. If compile fails, it what compiled before.
I have add this in makefile :
libopenocd_la-detection.lo: detection.c
$(LIBTOOL) --tag=CC $(AM_LIBTOOLFLAGS) $(LIBTOOLFLAGS)
--mode=compile $(CC) $(DEFS) $(DEFAULT_INCLUDES) $(INCLUDES)
$(libopenocd_la_CPPFLAGS) $(CPPFLAGS) $(AM_CFLAGS) $(CFLAGS) -MT
libopenocd_la-detection.lo -MD -MP -MF
$(DEPDIR)/libopenocd_la-detection.Tpo -c -o
libopenocd_la-detection.lo `test -f 'detection.c' || echo
'$(srcdir)/'`detection.c
$(am__mv) $(DEPDIR)/libopenocd_la-detection.Tpo
$(DEPDIR)/libopenocd_la-detection.Plo
# source='detection.c' object='libopenocd_la-detection.lo'
libtool=yes \
# DEPDIR=$(DEPDIR) $(CCDEPMODE) $(depcomp) \
# $(LIBTOOL) --tag=CC $(AM_LIBTOOLFLAGS) $(LIBTOOLFLAGS)
--mode=compile $(CC) $(DEFS) $(DEFAULT_INCLUDES) $(INCLUDES)
$(libopenocd_la_CPPFLAGS) $(CPPFLAGS) $(AM_CFLAGS) $(CFLAGS) -c -o
libopenocd_la-detection.lo `test -f 'detection.c' || echo
'$(srcdir)/'`detection.c
and it's create libopenocd_la-detection.o
Is the .o file linked into the .a/.la file?
How can I know this ?
I have it in libopenocd.a (if this is want you wanna know)
Is the .a/.la file linked into the final target?
No because it fail before the end of compilation :)
