[Expat-discuss] Statically linking against expat libs

[Dan Clusin]

Good day everyone,

 

I'm trying to write a program that statically links against expat. The
target platform I am writing for is an embedded arm board running
embedded linux (using uClibc). When I compile my program using the
vendor provided tool-chain (gcc variant targeting the arm platform) I
get the following error:

 

/usr/local/arm/3.4/bin-ccache/../lib/gcc/arm-linux-uclibc/3.4.3/../../..
/../arm-linux-uclibc/bin/ld: cannot find
-l/home/dclusin/Development/obvius_libs/expat/lib/libexpat.a

 

The libexpat.a archive does exist there. I have google searched for this
particular problem, but haven't found any useful advice. Most of the
static linking advice that I have seen doesn't pertain to expat, or
doesn't solve my problem. I have configured the source for expat using
the following options:

 

./configure --prefix=/home/dclusin/Development/obvius_libs/expat/
--host=arm-linux-uclibc CC=/usr/local/arm/3.4/bin/arm-linux-gcc
LFLAGS=-s

 

The relevant section of my makefile is as follows:

 

CC=/usr/local/arm/3.4/bin/arm-linux-gcc

CFLAGS= -O3 -Wall -c

LFLAGS= -static

 

OBVIUS_LIBS=/home/dclusin/Development/obvius_libs/

LIBRARIES=-l$(OBVIUS_LIBS)/expat/lib/libexpat.a

 

#...

#$(objects) is rather long so I left it out for clarity's sake.

myApp: $(objects)

            $(CC) $(LFLAGS) $(LIBRARIES) -o myApp $(objects)

 

Perhaps it could be because I mis-configured my source build of expat,
or I have inadvertently screwed something up in my make file. Any ideas
that you can offer are greatly appreciated. If you need more
information, please don't hesitate to ask. I tried to provide everything
I thought was pertinent with out giving you the kitchen sink.
