openSSL build error

Hello,

I am following tschmelcher written guide "sshd-guide".

http://forum.niosforum.com/forum/index.php?showtopic=3252 (http://forum.niosforum.com/forum/index.php?showtopic=3252)

In the first step:

1. I downloaded the openssl-0.9.7e.tar.gz file to ~/download

2. build with "make" command.

it gave following error:

**********************************************************************

make[1]: Entering directory `/home/goutam/buildroot/build_nios2/openssl-0.9.7e'

libs='-L. '; for i in crypto ssl; do

if [ "crypto ssl" = "ssl" -a -n "" ]; then

libs=" $libs";

fi;

( set -x; /home/goutam/buildroot/build_nios2/staging_dir/bin/nios2-linux-uclibc-gcc

-shared -o lib$i.so.0.9.7

done

    The error does not matter because it is post building the libcrypto.a and the libssl.a. The error appears when applications for SSL are build which we do not need. The error happens because the Nios does not support shared libs.

    If you want to compile without error make following lines a comment in openssl.mk file:

    $(OPENSSL_DIR)/apps/openssl: $(OPENSSL_DIR)/Makefile

    $(MAKE1) CC=$(TARGET_CC) -C $(OPENSSL_DIR) all

    # Work around openssl build bug to link libssl.a with libcrypto.a.

    # -rm $(OPENSSL_DIR)/libssl.a.*.*.*

    # $(MAKE1) CC=$(TARGET_CC) -C $(OPENSSL_DIR) do_linux-shared
