betachen/tinychain

A simple and useful blockchain instance for learning blockchain technology.

tinychain's Issues

Compile failed.

The build can not pass.

First error:
c++: error: unrecognized command line option ‘-std=c++14’
Solution:
Then I change ‘-std=c++14’ to ‘-std=c++1y’.

Senond error:

Solution:
I do not know how to solve this problem.

windows下Cmake构建后bin下无可执行文件

cmake构建完成后bin下找不到可执行文件
cmake版本3.18.3

window下编译出错

通过cmake可以构建出tinychain的工程文件，但是打开工程之后build会报错，错误信息如下：

烦请指教。

在Docker 裡面的Ubuntu:16.04環境中，編譯成功後，執行tinychain報錯 出現segmentation fault

請教作者，我按照你的書上面的附錄Ｃ去實作編譯tinychain
在Docker 裡面的Ubuntu:16.04環境中，編譯成功後，執行tinychain報錯 出現segmentation fault
請問我該如何解決？ 謝謝回答

能否给代码文件夹写一个说明文档

看了《深入浅出区块链》的课程，想来学习代码，不知道从何看起，能否写一个简要的阅读指引。

make报错：ld: library not found for -lcryptopp

你好~我在OSX 10.14上编译，已经通过brew install cryptopp成功安装了cryptopp，cmake ..也执行成功了，但是在make时报如下错误：

当前安装情况：

Apple LLVM version 10.0.0 (clang-1000.11.45.2)
Target: x86_64-apple-darwin18.0.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

尝试过删除 build文件夹重新cmake，但依然报上述错误。麻烦帮忙看一下，谢谢~~

在macOS平台上编译报错

macOS 10.13.5
Xcode 9.4.1

用make指令编译链接的时候的时候报错如下：

Desktop/tinychain/include/tinychain/database.hpp:64:77: error: lambda
      capture 't' is not used [-Werror,-Wunused-lambda-capture]
  ...auto iter2 = std::find_if(tl.begin(), tl.end(), [&tx_hash, &t](const tx& t){

这个好像是苹果自带编译器的问题，陈老师这个问题是不是有方便的方法来解决啊？
我看到WebKit里面类似的错误好像是通过修改c++源码来解决的，但是c++我不熟悉，请求陈老师抽空看一下吧~
