Has anyone been successful in compiling OpenSSL for the NAS as a dynamic library?
The source code uses a weird configuration script, which makes it a bit difficult to set up.

Here's what I tried with openssl-0.9.8g:

Code:

./Configure linux-generic32 -DL_ENDIAN shared
make CC=arm-linux-gcc RANLIB=arm-linux-ranlib AR="arm-linux-ar r"

This compiles just fine, and .so files are produced as expected. But on the NAS, an executable using the libssl.so and libcrypto.so files complains that I shall compile them with -fPIC, which as far as I can tell they are!

Here's what I use:

Code:

    ./Configure linux-elf \
        --prefix=$CPREFIX \
        --openssldir=$CPREFIX/etc/ssl \
        zlib shared no-asm

    make CC=$CC RANLIB=$RANLIB
    make CC=$CC RANLIB=$RANLIB INSTALL_PREFIX=$D install

Alternatively you can set CFLAGS to -fPIC before running configure to make sure you compile with that flag. "CFLAGS=-fPIC; export CFLAGS"

PS: Here's a way to test which lib really is the culprit.

Thanks for the link.
Running the shell script revealed that 2 of my compiled libraries have the mentioned problem, libxml2.so.2.6.31 and libcrypto.so.0.9.8.
Interestingly, libssl.so.0.9.8 does not have the problem.

I tried several things with the compilation, but am so far unable to find a solution.
Here are my build scripts for both libraries:

openssl:

Code:

#!/bin/bash
source ../setpath
CC=arm-linux-gcc
RANLIB=arm-linux-ranlib
CPREFIX=/home/kylek/crosscompile/ch3snas

./Configure linux-generic32 --prefix=$CPREFIX --openssldir=$CPREFIX/etc/ssl zlib shared no-asm \
                             -I${CPREFIX}/include -L${CPREFIX}/lib
export CFLAGS=-fPIC
make CC=$CC RANLIB=$RANLIB install

libxml2:

Code:

#!/bin/bash
source ../setpath
CPREFIX=/home/kylek/crosscompile/ch3snas

./configure --prefix=$CPREFIX --build=i686 --host=arm-linux --with-pic \
                --with-zlib=$CPREFIX/lib

Compiling statically works just fine, any reason why I should prefer dynmically linked binaries?
