compile errors

[osoese]

1) Block.cpp:6:23: error: 'time' was not declared in this scope _tTime = time(NULL);

• I was able to get rid of this one with #include

but the rest of these are puzzling me and I am not the best at C++ any ideas appreciated

2) C:\Users\\src\github.com\testchain>g++ -o testchain -std=c++11 main.cpp Block.cpp Blockchain.cpp sha256.cpp Block.cpp: In member function 'void Block::MineBlock(uint32_t)': Block.cpp:44:12: error: 'sHash' was not declared in this scope while (sHash.substr(0, nDifficulty) != str) ^ Block.cpp:56:32: error: 'sHash' was not declared in this scope cout << "Block mined: " << sHash << endl; ^ Block.cpp: In member function 'std::__cxx11::string Block::_CalculateHash() const': Block.cpp:66:18: error: aggregate 'std::stringstream ss' has incomplete type and cannot be defined stringstream ss; ^

@osoese you did not forget to delete the lines? `#ifndef TESTCHAIN_BLOCK_H

define TESTCHAIN_BLOCK_H

...

endif`

similarly on g++ at me all was compiled

@AlexNickrodef I did not include those lines. I didn't use repo just wrote the code as I went through your write up then compared to repo. I also did not start with canned IDE code just a text editor and compile using gcc and g++. Thank you for the reply.

If you clone the repo and compile with the following command without making any changes to the code:

gcc -lstdc++ \
    -o TestChain \
    -std=c++11 \
    -stdlib=libc++ \
    -x c++ \
    main.cpp Block.cpp Blockchain.cpp sha256.cpp

If you use "g++" compiler, this command g++ -std=c++11 main.cpp Block.cpp Blockchain.cpp sha256.cpp -o TestChain would work.
