Hi all!
This is kind of out there, but hoping someone might know what I did wrong.
I am trying to add a STRAIGHT_TRAVERSE2 function right next to the original
STRAIGHT_TRAVERSE function in the code.
I did the following:
1. Added a STRAIGHT_TRAVERSE2 function in src/emc/task/emccanon.cc (This
already contains the original STRAIGHT_TRAVERSE function)
2. Added an extern declaration for STRAIGHT_TRAVERSE2 in
/src/emc/nml_intf/canon.hh (This already contains an extern declaration for
the original STRAIGHT_TRAVERSE function)
3. I try to call STRAIGHT_TRAVERSE2 in the
/src/emc/rs274ngc/interp_convert.cc file right below a call to the original
STRAIGHT_TRAVERSE function.
When trying to build this, I get the following error
Linking rs274
g++ -L/home/lawrence/emc2-dev/lib -Wl,-rpath,/home/lawrence/emc2-dev/lib -o
../bin/rs274 objects/emc/sai/saicanon.o objects/emc/sai/driver.o
objects/emc/rs274ngc/tool_parse.o ../lib/librs274.so.0 ../lib/libemcini.so.0
-Wall -g -I. -I/home/lawrence/emc2-dev/src/include -DULAPI -D_GNU_SOURCE -Os
-DLOCALE_DIR=\"/usr/share/locale\" -DPACKAGE=\"emc2\"
../lib/librs274.so.0: undefined reference to `STRAIGHT_TRAVERSE2(int,
double, double, double, double, double, double, double, double, double)'
collect2: ld returned 1 exit status
I must be doing something wrong but I can not for the life of me figure out
what it is. My implementation of STRAIGHT_TRAVERSE2 is right below the code
for STRAIGHT_TRAVERSE in emccanon.cc and my external declaration for
STRAIGHT_TRAVERSE2 is right below the external declaration for
STRAIGHT_TRAVERSE in canon.hh .
Anybody suggest anything I can try? I really don't understand why the
linker is saying undefined reference when it is defined...
Thanks in advance!
