Unable to find 'openssl/opensslv.h'

[GoPerry]

For Ubuntu16.04 , i meet same build error about opensslv.h .

Solution: apt-get install libssl-dev

[ChuckIT]

Took this approach to but once libssl-dev was installed
python setup.py install --user
fails with

SWIG/_evp.i:12: Error: Unable to find 'openssl/opensslconf.h'
SWIG/_ec.i:7: Error: Unable to find 'openssl/opensslconf.h'
error: Setup script exited with error: command 'swig' failed with exit status 1

Investigation yields that the the following option may be missing from the call to swig

-I/usr/include/x86_64-linux-gnu

I can verify through find that
/usr/include/x86_64-linux-gnu/openssl/opensslconf.h
exists on my system
Thanks

What is your OS? Please try pip install --user M2Crypto and if that fails while headers are available, then it's M2crypto bug and should be reporter in their tracker.

I'm running a fresh updated install of Ubuntu 14.04.1 (3.13.0-39-generic) with the following installed Apt-get install gitApt-get install lamp-server^Git clone https://Github ‎.com/letsencrypt/lets-encrypt-preview.gitApt-get install python....etcChecked for opensslconf.h...not found so installed Apt-get install libssl-devOpensslconf.h was now there.I tried to run pip install M2Crypto but needed pip installed so afterApt-get install pipAnd running Sudo pip install M2Crypto The package installed correctly Running python setup.py install --user now ran cleanly. ‎Could this have something to do with installing pip? Ran into problem with. / letsencrypt after that but that may be an apache server configuration issue. I'll retry to see if pip install made a difference. Thanks Chuck Peeren (226)[email protected] From: Jakub WarmuzSent: Thursday, November 20, 2014 15:01To: letsencrypt/lets-encrypt-previewReply To: letsencrypt/lets-encrypt-previewCc: ChuckSubject: Re: [lets-encrypt-preview] Unable to find 'openssl/opensslv.h' (#37)What is your OS?

Did you get it working? If you describe the problem when running ./letsencrypt.py I can probably help debug.

On fresh trusty, before apt-get install libssl-dev I do get:

but, then, after sudo apt-get install libssl-dev it installs correctly.

I think strictly speaking this is an upstream bug in the Python M2Crypto package, so having our own dependency on libssl-dev could be seen as a workaround rather than a fix to the underlying bug.

[kuba]

M2Crypto needs openssl headers to compile. It doesn't look like a bug, does it?

[schoen]

I'm not quite sure how pip is supposed to handle the need for development headers.

Now that I think of it, I have gotten header-related errors when installing things in pip before, and I then used my system package manager to get them, so I guess that's a common occurrence that isn't regarded as an upstream bug.

‎Thanks I can confirm that the updated procedure works for me now on a fresh install. The only issue is that the procedure does not enable the new site I did it manually and restarted apache and the https site came up. Thanks again.

Hmm... alright. I really haven't tested nearly as much as I should have on Ubuntu 14.04 Apache 2.4. The configurator code was originally designed on Ubuntu 12.04 running Apache 2.2. I am guessing it might have to do with 2.4 requiring that all configuration files in sites-available/enabled to end in *.conf. (2.2 didn't have this restriction) At least that is what held me up when I did my setup on Apache 2.4. (I did record the demo video on 2.4 but I haven't messed around with many configurations)

I am really glad you got it up and running, solved the DVSNI challenge, issued and installed a cert.

I will be tackling and updating the apache_configurator.py class over the weekend to handle 2.4 properly. Hopefully hardening the code quite a bit and solving issues like sites not enabling properly. Any insight you have would be greatly appreciated or if you would like to dive in with me... I accept patches!

Thanks for your interest in the project and for helping us work through the problems with installation!
