Error compiling librdkafka

[adamof]

In case anyone else is seeing this on os X, I was able to install the library by specifying the following paths to openssl libs:

CPPFLAGS="-I/usr/local/opt/openssl/include" LDFLAGS="-L/usr/local/opt/openssl/lib" gem install rdkafka

The values are taken from the brew post-installation message of openssl (brew install openssl)

Thanks for that! I'm considering adding some platform detection logic to set sensible defaults like this.

Looks like the compile process is having trouble locating OpenSSL. Are you using OpenSSL 1.0? How did you install it?

We still need to do some work on installation instructions.

@thijsc I installed it using Homebrew.
It is this version:

openssl: stable 1.0.2o (bottled) [keg-only]
SSL/TLS cryptography library
https://openssl.org/
/usr/local/Cellar/openssl/1.0.2o_1 (1,791 files, 12.3MB)

/usr/local/Cellar/openssl/1.0.2o_2 (1,792 files, 12.3MB)

Are any of the tips here helpful?
confluentinc/librdkafka#1639

It’s not really in the scope of this gem to handle this. But i would like to add some error handling with debug output and hints on what to do. If you can do a bit of digging that would be very good input.

[thijsc]

@lephyrius did you make progress on this?

[thijsc]

Closing until more information is added here.

[thijsc]

@lephyrius I might have fixed this in #61. Could you test by https://github.com/appsignal/rdkafka-ruby#development in that branch?

[thijsc]

Closing this for now, hopefully #61 improves things. If not we'll reopen.

@thijsc I had the same problem today. The fix from @adamof solved it for me.
-- edit: I just realize that the fix you mentioned above is not yet deployed, so that was the reason I had to use the work-around.
