Compile Lib

Build libc_opentimestamps shared library and main sample binary.

mkdir build
cd build
cmake ../
make

Import and Run

The sample main.cpp imports and uses shared library. To compile successfully follow:

g++ main.cpp -o main -L./build/ -lc_opentimestamps
./main

Problems Compiling

If cmake ../ result's is somethings similar to:

{…omissis…}
CMake Error at /usr/local/{…omissis…}/cmake/Modules/FindPackageHandleStandardArgs.cmake:137 (message):
  Could NOT find OpenSSL, try to set the path to OpenSSL root folder in the
  system variable OPENSSL_ROOT_DIR (missing: OPENSSL_INCLUDE_DIR)
{…omissis…}

you can specify the right path to OpenSSL in OPENSSL_ROOT_DIR; for example:

cmake -DOPENSSL_ROOT_DIR=/usr/local/opt/openssl ../

to debug:

cmake -DOPENSSL_ROOT_DIR=/usr/local/opt/openssl -DCMAKE_BUILD_TYPE=Debug ../
