I have install openssl library using make menuconfig, after that I have tried the program using the crosscompling as shown:

mipsel-linux-gcc client.c -o client -lssl

and I got the folowing errors:

In file included from client.c:1:
sockets.h:12:25: openssl/rsa.h: No such file or directory
sockets.h:13:25: openssl/evp.h: No such file or directory
sockets.h:14:25: openssl/pem.h: No such file or directory
client.c: In function `main':
client.c:12: error: `RSA' undeclared (first use in this function)
client.c:12: error: (Each undeclared identifier is reported only once
client.c:12: error: for each function it appears in.)
client.c:12: error: `key' undeclared (first use in this function)
client.c:12: error: `key2' undeclared (first use in this function)
client.c:36: error: `RSA_PKCS1_PADDING' undeclared (first use in this function)

So I tried this way because I knew where those files ware:

mipsel-linux-gcc -I/home/jchorro/whiterussian/openwrt/staging_dir_mipsel/usr/include -L/home/jchorro/whiterussian/openwrt/staging_dir_mipsel/usr/lib  client.c -lssl

And I got the folowing errors.

client.c:(.text+0x350): undefined reference to `PEM_read_RSAPrivateKey'
client.c:(.text+0x3a4): undefined reference to `RSA_private_encrypt'
client.c:(.text+0x3bc): undefined reference to `RSA_free'

I think you need to link against libcrypto too.

Thank you, you are right, but I had to do some thing elese, here is the hole command line:

mipsel-linux-gcc -I/home/jchorro/whiterussian/openwrt/staging_dir_mipsel/usr/include -L/home/jchorro/whiterussian/openwrt/staging_dir_mipsel/usr/lib  client.c -o client  -lssl  -lcrypto

and I had to add another include

<openssl/pem.h>

And I want to remark that compiling for linux 2.6 in a pc it was only necesary de -lssl option.

Regards.

I have a similar problem - yet to be solved... I would like to do EAP-TLS authentication with pppd, for which a patch is needed: http://eaptls.spe.net/download/ppp-2.4. … -0.7.patch. I've already had success with this patch on Fedora and Ubuntu, works like a charm. smile (There's one more thing: the ssl.h in newer OpenSSL versions must also be patched like this:)

Patching OpenSSL works fine, at least compiling doesn't end there (and without the pppd patch everything compiles fine). At pppd however, with V=99 I see the following error:

mipsel-linux-uclibc-gcc -Os -pipe -mips32 -mtune=mips32 -funit-at-a-time -fhonour-copts -DHAVE_PATHS_H -DHAVE_MMAP -I../include -DCHAPMS=1 -DMPPE=1 -DHAVE_CRYPT_H=1 -DUSE_CRYPT=1 -DPLUGIN -DPPP_FILTER -DPPP_PRECOMPILED_FILTER -I/home/neutron/OpenWRT/trunk/staging_dir/mipsel/usr/include -DINET6=1 -DMAXOCTETS -Wl,-E -o pppd main.o magic.o fsm.o lcp.o ipcp.o upap.o chap-new.o md5.o ccp.o ecp.o auth.o options.o demand.o utils.o sys-linux.o ipxcp.o tty.o eap.o chap-md5.o eap-tls.o md4.o chap_ms.o sha1.o pppcrypt.o pcap_pcc.o ipv6cp.o eui64.o -lssl -lcurl -lcrypt -ldl /home/neutron/OpenWRT/trunk/staging_dir/mipsel/usr/lib/libpcap.a

collect2: ld returned 1 exit status
make[5]: *** [pppd] Error 1

So I guess compiling is fine, but linking fails... The steps I took were the following:
1. check out trunk from the svn repository
2. make package/symlinks
(2.1, 2.2, etc.: make menuconfig, build fancy new firmware for my Asus WL-500gP v1 smile)
3. copy openssl patch into trunk/package/openssl/patches/190-ssl_md5.patch
4. copy pppd patch into trunk/package/ppp/patches/320-eaptls.patch
5. make V=99

What am I doing wrong?

Adam
