Re: Compiling shared libraries
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

CFLAGS = -G -I. -DUNIX
CFLAGS_COMPILE_ONLY = -c -DUNIX
LIBS = -lmqm

Make sure when you cut and paste this makefile that the indented lines use
a single tab and NOT spaces.

Subject: Compiling shared libraries
Howdy all,
I am porting some C++ MQ code from Win32 to Linux and have never used shared
libraries.
While I can comile my MQ code, I cannot figure out how to link the shared
libraries (static libraries are ok).
Can anyone give me some usefull pointers ?
Sid

Re: Compiling shared libraries
Try linking with the gcc -G option (gcc -G module1.o module2.o etc.) I think that creates shared libraries on Linux. Try gcc --help or search the web fore details on gcc.
