@sagrawal87 Same error here , same configuration as Rocky before. Any solution so far?

Hi. I haven't seen this error before. May be try the newer version of Charm, Charm 0.43, which I used. It can be downloaded from here.

Let me know if the error doesn't go away.

@sagrawal87 tried it with Charm 0.43 and still the same error

@emantas @sagrawal87 Hi, everyone, I also tried Charm 0.43 on my Mac OS(High Sierra10.13, Python 2.7.11). After Installing GMP 5.x, PBC, OpenSSL, I download the Charm-Crypto-0.43_Python2.7.tar.gz (Python 2.7 Source) on my laptop, when executing "make", I meet this error:

I am wondering whether it caused by my openssl installation, have you meet this error before?

@sagrawal87 Hi Shashank, can I ask you which is your Charm 0.43 version? Charm-Crypto-0.43.dmg (Mac OS X 10.6+ Installer) or Charm-Crypto-0.43_Python2.7.tar.gz (Python 2.7 Source)？Have you test your code under Charm-dev?

from abe.

The DMG file is an easy way to install charm. Just download, extract, and follow the instructions in README-OSX.rtf. I think dependencies like PBC, OpenSSL, etc. are automatically taken care of.

Hi Shashank, Thanks for your response, well, I still failed in my Macbook, but then I have deployed it successfully in my Ubuntu 12.04 with Charm 0.42 and Python 3.2.3. The AC17 and BSW07 scheme has been tested correctly. 👍 But there is another issue about CGW15 and waters11 scheme. I will open a new topic to talk with you more.
