比特币编译（.undefined reference to `BlockAssembler::BlockAssembler(CChainParams const&)'）

Question

make 命令后出现错误，

对`BlockAssembler::BlockAssembler(CChainParams const&)'的未定义引用

最后

Makefile:774: 目标 'all-recursive' 的配方失败

make: **[全递归] 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？

本教程帮我解决了这个问题。

通过，遵循 Unix 构建说明，

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

下载需要的依赖即可解决问题。我认为问题是由于 Berkeley DB 安装不当造成的，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！
