c++ - 比特币编译（.undefined 对 `BlockAssembler::BlockAssembler(CChainParams const&)' 的引用）

问题描述

make 命令后出现错误，例如，

未定义对“BlockAssembler::BlockAssembler(CChainParams const&)”的引用

最后

Makefile:774: 目标“全递归”的配方失败

make: **[all-recursive] 错误 1

我已按照此处给出的所有步骤进行操作：-

如何解决这个错误并成功编译比特币源代码？

解决方案

本教程帮助我解决了这个问题。

通过，按照 Unix 构建说明，

https://github.com/bitcoin/bitcoin/blob/master/doc/build-UNIX.md

并下载所需的依赖项可以解决问题。我认为问题是由于 Berkeley DB 安装错误导致的，所以我删除了所有旧文件，然后再次按照 build-UNIX.md 中的步骤操作。

并下载依赖项，

sudo apt-get install build-essential libtool autotools-dev automake pkg-config bsdmainutils python3  

sudo apt-get install libssl-dev libevent-dev libboost-system-dev libboost-filesystem-dev libboost-chrono-dev libboost-test-dev libboost-thread-dev

sudo apt-get install software-properties-common
sudo add-apt-repository ppa:bitcoin/bitcoin
sudo apt-get update
sudo apt-get install libdb4.8-dev libdb4.8++-dev

这对我有用。谢谢！
