Andrew Stitcher commented on PROTON-1558:
-----------------------------------------
Hmm, this seems to be because your system doesn't have pkg-config installed,
which is what the script uses to detect openssl (and cyrus-sasl as well).
I wonder what we can do in that case - can we not assume *any* prior tools at
all?

> Key: PROTON-1558
> URL: https://issues.apache.org/jira/browse/PROTON-1558
> Project: Qpid Proton
> Issue Type: Bug
> Components: python-binding
> Affects Versions: proton-c-0.17.0
> Environment: Ubuntu 16.04
> Reporter: Itamar Landsman
> Priority: Major
>
> When installing python-qpid-proton from pip there is no ssl support.
> Trying to build the package (pip download, untar and setup.py build) I get a
> warning about OpenSSL not installed:
> {quote}ยป python setup.py build
> running build
> running build_ext
> running configure
> Warning: command not found: pkg-config
> Building the bundled proton-c sources into the extension
> Warning: command not found: pkg-config
> Warning: OpenSSL not installed - disabling SSL support!
> creating build
> .
> .
> .
> {quote}
> And indeed SSL is not available for the resulting built package.
> A hack fix is to go into setup.py and edit the section where the presence of
> OpenSSL is verified:
> {quote}\# Check whether openssl is installed by poking
> \# pkg-config for a minimum version 0. If it's installed, it should
> \# return True and we'll use it. Otherwise, we'll use the stub.
> if misc.pkg_config_version_installed('openssl', atleast='0'):
> libraries += ['ssl', 'crypto']
> sources.append(os.path.join(proton_src, 'ssl', 'openssl.c'))
> else:
> sources.append(os.path.join(proton_src, 'ssl', 'ssl_stub.c'))
> log.warn("OpenSSL not installed - disabling SSL support!"){quote}
> Change to:
> {quote}\# Check whether openssl is installed by poking
> \# pkg-config for a minimum version 0. If it's installed, it should
> \# return True and we'll use it. Otherwise, we'll use the stub.
> if True:
> libraries += ['ssl', 'crypto']
> sources.append(os.path.join(proton_src, 'ssl', 'openssl.c'))
> else:
> sources.append(os.path.join(proton_src, 'ssl', 'ssl_stub.c'))
> log.warn("OpenSSL not installed - disabling SSL support!"){quote}
> Now, package is indeed built with SSL support.
> The library discovery mechanism needs to be fixed, I expect.
