Howdy John et al,
Thanks to everyone who sent me an email, after "playing" all night, I came
up with the following two make files. The first builds my shared library,
the second links the MQ C++ shared libraries (and mine) into a test program.
I sugest you file this one away because it is bound to be usefull.

Here is a makefile for Linux. This makefile compiles test1.c into a shared
library of test1.so
+++++++++++++ cut here ++++++++++++++
# Makefile
CC = cc
CFLAGS = -G -I. -DUNIX
CFLAGS_COMPILE_ONLY = -c -DUNIX
LIBS = -lmqm
#
.c.o:
${CC} ${CFLAGS_COMPILE_ONLY} ${CFLAGS} $<
OBJ = test1.o
all: test1.so
test1.so: ${OBJ}
${CC} ${CFLAGS} -G -o $@ ${OBJ} ${LIBS}
+++++++++++++ cut here ++++++++++++++
Make sure when you cut and paste this makefile that the indented lines use
a single tab and NOT spaces.
later
Roger...
