Here is what I did:
I first bega by configuring the OpenSSL toolkit from source, supplying
configure with the following arguments:
./Configure --prefix==/home/dclusin/Development/obvius_libs/openssl
linux-generic32 -DL_ENDIAN -static
I then edited the Makefile in OpenSSL's source directory to use my
vendor's tool chain. (/usr/local/arm/3.4/bin/arm-linux-*: gcc, ar,
ranlib)
My makefile contains the following:
CC = arm-linux-gcc
CFLAGS = -O3 -Wall -c
LFLAGS = -static
OBVIUS_LIBS = /home/dclusin/Development/obvius_libs
INCLUDES = -I./ -I$(OBVIUS_LIBS)/expat/include
-I$(OBVIUS_LIBS)/gsasl/include \
-I$(OBVIUS_LIBS)/openssl/include/
LIBRARY_PATHS = -L$(OBVIUS_LIBS)/expat/lib/ -lexpat
-L$(OBVIUS_LIBS)/gsasl/lib/ -lgsasl \
-L$(OBVIUS_LIBS)/openssl/lib/ -lcrypto -lssl -lpthread
objects = main.o iq.o xmpp.o xml_node.o parser.o linked_queue.o socket.o
powertalk: $(objects)
$(CC) -o powertalk $(objects) $(LFLAGS) $(LIBRARY_PATHS)
main.o: main.c
$(CC) $(CFLAGS) $(INCLUDES) main.c
iq.o: xmpp/iq.c
$(CC) $(CFLAGS) $(INCLUDES) xmpp/iq.c
xmpp.o: xmpp/xmpp.c
$(CC) $(CFLAGS) $(INCLUDES) xmpp/xmpp.c
xml_node.o: xml/xml_node.c
$(CC) $(CFLAGS) $(INCLUDES) xml/xml_node.c
parser.o: xml/parser.c
$(CC) $(CFLAGS) $(INCLUDES) xml/parser.c
linked_queue.o: Util/linked_queue.c
$(CC) $(CFLAGS) $(INCLUDES) Util/linked_queue.c
socket.o: Util/socket.c
$(CC) $(CFLAGS) $(INCLUDES) Util/socket.c
.PHONY: clean
clean:
rm powertalk $(objects)
When I go to build it compiles fine, but linking yields the following
output:
make powertalk
arm-linux-gcc -o powertalk main.o iq.o xmpp.o xml_node.o parser.o
linked_queue.o socket.o -static

/* Truncated... More undefined references to SSL stuff. */
I don't think that it an issue of the entire library not being built,
because I am able to run the OpenSSL command line utility on my target
box when I compile it. Perhaps I could be off base. Any input on this
issue is very much appreciated.
P.S. Sorry for the HTML; I turned it off in outlook.

(don't use HTML while posting to mailing-lists).
What does the command-line (link command) looks like?
Remember the order of libs are important.
