OpenSSL Crypto headers not found.

I'm trying to configure OperVpn but an error appears : OpenSSL Crypto headers not found.. I installed ssl again but i can't fix the problem.

Thanks!!!

I got the same problem with you, when I run ./configure I get this output

Code:

configure: checking for OpenSSL Crypto Library and Header files... 
checking openssl/evp.h usability... no 
checking openssl/evp.h presence... no 
checking for openssl/evp.h... no 
configure: error: OpenSSL Crypto headers not found

evp.h exists at /usr/local/ssl/include/openssl

I also tried

Code:

./configure --with-ssl-headers=/usr/local/ssl/include/openssl/

but nothing better.

I've google it and found that:

Code:

export LDFLAGS="-lkrb5" 
./configure

and nothing happened again

I got OpenSSL 0.9.6c but OpenVpn 2.0 betta 11 requires version 0.9.5 or higher.
I hope someone who knows something more, make a hint...

Finaly, I tried

Code:

./configure --with-ssl-headers=/usr/local/ssl/include/

and the problem passed but stopped with another error of

Code:

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.

so I tried

Code:

./configure --with-ssl-headers=/usr/local/ssl/include/ --disable-crypto

and finished normally. With this action, I suppose that I bypassed the packet encryption (--disable-crypto Do not compile OpenSSL crypto support) and I hope it's gonna work

I did

Code:

make
make install

with success.

Hi, i am not sure if the answer has been answered yet.. and i came across the same question in multiple bbs's/ forums (as i had the same problem).
Then i remembered that i can just install the libssl-dev package which carries the header files which break the .configure..
So. installed the dev package ran the config script again (make; make install and openVPN installed without further problems..

Maybe you are right but
when I had those kind of problems, I've had already OpenSSL 0.9.6c [engine] 21 dec 2001. I didn't try to install a newer version.

MarvTowel · 01-27-2006, 10:49 PM

I used YaST and searched for ssl. I installed the only ssl developement package found and tada, problem solved.

kd2323 · 02-04-2008, 05:51 PM

I ran into this same problem on ubuntu and to fix it I downloaded libssl0.9.8 and libssl-dev and the openvpn installed without a problem.

Tosh2o · 03-24-2008, 01:00 PM

And another way to compile with no errors not for ubuntu users:

Code:

./configure --with-ssl-headers=/usr/local/ssl/include/ \
--with-ssl-lib=/usr/local/ssl/lib/

Для русских:
Еще один метод компиляции openVPN без ошибок это прописать путь не только к инклудам ssl но и к откомпиленной библиотеке:

Code:

./configure --with-ssl-headers=/usr/local/ssl/include/ \
--with-ssl-lib=/usr/local/ssl/lib/

Если вы ставили ssl в другую папку - исправьте пути!
If you have installed ssl in another directory then you should to replace paths!

issen007 · 08-27-2008, 06:10 AM

I just installed OpenVPN on my OpenSuSE 11 x86_64 installation.
I needed to install libopenssl-devel packed and also zlib-devel packed.
After that then did the ./configure go though without any extra exclude switches.

Cheers

Some how I managed to solve the Crypto Headers problem, it's been a while so I can't really remember what I did. When I started this thread OpenVPN was going to be used as a class project and I believe it would have been against the rules to help me with it. I already graduated so it's cool.

In the end when I tried to connect to the server I would never receive the confirmation that it was successful, I also tried OpenSwan but I didn't have much luck with it.

I remember now, I was using Ubuntu at the time and I went into Synaptic and did a search for SSL and downloaded everything that seemed relevant. It was like killing flies with a rocket launcher. Give me time to dive back in to my notes and I will then be of more assistance.

ndedobbeleer · 12-11-2008, 05:23 AM

I Had the same error and installed the DEV packages and it worked.....

# apt-get install libcurl4-openssl-dev
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following extra packages will be installed:
comerr-dev libidn11-dev libkadm55 libkrb5-dev libldap2-dev libssl-dev zlib1g-dev
Suggested packages:
libcurl3-dbg krb5-doc
The following NEW packages will be installed:
comerr-dev libcurl4-openssl-dev libidn11-dev libkadm55 libkrb5-dev libldap2-dev
libssl-dev zlib1g-dev

BaRYaN · 04-03-2009, 02:30 AM

I have CentOS 5.
I'm just update openssl and openssl-devel.

yum install openssl
yum install openssl-devel

After this all its work.

mrkylekervin · 07-29-2010, 09:40 AM

ok so just get the latest OpenSSL from openssl.net, install it.

Then after that's done, go and configure your openvpn package:

./configure --with-ssl-headers=/usr/local/ssl/include/ --with-ssl-lib=/usr/local/ssl/lib/

you shouldn't receive any openssl errors.

Chaaaaaaaz · 12-09-2010, 06:24 AM

I had the same problem recently and found that installing the openssl-dev package resolved the issue.

sudo apt-get install openssl-dev
