Error making Scapi (libOTe)

[Ruth1993]

Hi people,

When I make Scapi, I get the following error in building libOTe on Ubuntu 18.04:

[ 40%] Building CXX object cryptoTools/frontend_cryptoTools/CMakeFiles/frontend_cryptoTools.dir/Tutorials/Network.cpp.o [ 41%] Building CXX object cryptoTools/frontend_cryptoTools/CMakeFiles/frontend_cryptoTools.dir/main.cpp.o [ 43%] Building CXX object cryptoTools/frontend_cryptoTools/CMakeFiles/frontend_cryptoTools.dir/signalHandle.cpp.o [ 45%] Linking CXX executable ../../bin/frontend_cryptoTools /usr/bin/ld: cannot find -lz collect2: error: ld returned 1 exit status cryptoTools/frontend_cryptoTools/CMakeFiles/frontend_cryptoTools.dir/build.make:150: recipe for target 'bin/frontend_cryptoTools' failed make[3]: [bin/frontend_cryptoTools] Error 1 make[3]: Leaving directory '/home/osboxes/libscapi/build/libOTe' CMakeFiles/Makefile2:253: recipe for target 'cryptoTools/frontend_cryptoTools/CMakeFiles/frontend_cryptoTools.dir/all' failed make[2]: [cryptoTools/frontend_cryptoTools/CMakeFiles/frontend_cryptoTools.dir/all] Error 2 make[2]: Leaving directory '/home/osboxes/libscapi/build/libOTe' Makefile:129: recipe for target 'all' failed make[1]: [all] Error 2 make[1]: Leaving directory '/home/osboxes/libscapi/build/libOTe' makefile:246: recipe for target 'compile-libote' failed make: [compile-libote] Error 2

Could anyone help me with this error? Thanks in advance!

Hello @Ruth1993,

Please install this library: sudo apt install zlib1g-dev. Afterwards run: make clean && make. I will add it to our install instructions.
