I am very sorry, I see the OpenVPN compilation thread was already discussed some months ago, but even following the Hans Eklund recipe at http://www.vpx.nu/dokuwiki/doku.php?id=vpn_solutions I still get errors.

Kernel compilation went smooth, I patch the kernel, enable libssl library and compile it. I install the new kernel and this is ok.

I start with compilink openvpn, download the 2.0.9 version, unpack and start configuring with

./configure --host=bfin-uclinux --disable-lzo --with-ssl-headers=../../lib/libssl/include/ --with-ssl-lib=../../lib/libssl CPPFLAGS="-DUCLINUX" LDFLAGS="-Wl,-elf2flt"

but it exit with an error

...

configure: checking for libdl Library and Header files...

checking dlfcn.h usability... yes

checking dlfcn.h presence... yes

checking for dlfcn.h... yes

checking for dlopen... no

checking for dlopen in -ldl... no

libdl library not found.

configure: checking for OpenSSL Crypto Library and Header files...

checking openssl/evp.h usability... yes

checking openssl/evp.h presence... yes

checking for openssl/evp.h... yes

checking for EVP_CIPHER_CTX_init in -lcrypto... no

configure: error: OpenSSL Crypto library not found.

If I look, libraries seem present in the --with-ssl-lib directory

# ls -la -s ../../lib/libssl/lib*a

2344 -rw-r--r-- 1 root root 2395028 2008-10-08 22:19 ../../lib/libssl/libcrypto.a

416 -rw-r--r-- 1 root root  418598 2008-10-08 22:19 ../../lib/libssl/libssl.a

EVP_CIPHER_CTX_init seems to be present in libcrypto.a

# nm ../../lib/libssl/libcrypto.a  | grep  EVP_CIPHER_CTX_init

00000000 T EVP_CIPHER_CTX_init

         U EVP_CIPHER_CTX_init

         U EVP_CIPHER_CTX_init

         U EVP_CIPHER_CTX_init

         U EVP_CIPHER_CTX_init

         U EVP_CIPHER_CTX_init

         U EVP_CIPHER_CTX_init

         U EVP_CIPHER_CTX_init

         U EVP_CIPHER_CTX_init

Any hint? is there the ipkg package for openvpn available for download?

this isnt the forum for ipkg as none of those are maintained with the normal uclinux-dist

you have to read the config.log to figure out the real error

Below is what I found related from config.log:

configure:9830: checking for openssl/evp.h

configure:9837: result: yes

configure:9842: checking for EVP_CIPHER_CTX_init in -lcrypto

configure:9872: bfin-uclinux-gcc -o conftest -g -O2 -DUCLINUX -I../../lib/libssl/include -I. -Wl,-elf2flt -L../../lib/libssl/ conftest.c -lcrypto   >&5

../../lib/libssl//libcrypto.so: could not read symbols: File in wrong format

collect2: ld returned 1 exit status

Please advise how to fix it.

Thanks.
