This is a shapshot from my working folder as I get undefined references
to...xxx
gcc -c main.c to get main.o
gcc main.o -L. -lctapi -o main.so to get main.so and where ctapi is the
library ctapi.lib or libctapi.a. I have both.
My .lib library is ctapi.lib
This is my working folder.
a@ALFRED ~/scm
$ ls
Ct_api.o SerialIFx.o T0Handlr.o ct_api.h libctapi.a main.h main.o
MagCard.o Stc.o T1Handlr.o ctapi.lib main.c main.lo
All the .os are from libctapi.a. My aim is to use the ctapi.lib, but it's
not working, so I tried with .a, still cannot. main.lo was created from
libtool
