freshclam：符号查找错误：freshclam：未定义符号：print_version，版本FRESHCLAM_PRIVATE

编程问答 2022-06-09

问题描述

我遵循this guide在Ubuntu 20.04 LTS上从源代码安装clamav，在遇到以下错误后我停止了运行：freshclam: symbol lookup error: freshclam: undefined symbol: print_version,version FRESHCLAM_PRIVATE 。 这是我发出的命令：

./configure --enable-check
make -j2
make check
make install
sudo cp /usr/local/etc/freshclam.conf.sample /usr/local/etc/freshclam.conf
sudo nano /usr/local/etc/freshclam.conf

在freshclam.conf中，我在Example之前添加了＃，以将其注释掉。 然后：

sudo mkdir /usr/local/share/clamav
freshclam
freshclam: symbol lookup error: freshclam: undefined symbol: print_version,version FRESHCLAM_PRIVATE

此错误是什么意思？

以下是./configure --enable-check并进行检查的输出：

./configure --enable-check

P.S。这不是我第一次尝试在此计算机上安装clamav。我第一次没有这个错误，但是在完成sudo make uninstall以完全删除clamav文件并从头开始安装之后，我手动删除了一些文件。我还删除了clamav用户和组，现在它们似乎不再自动创建，我想知道为什么。

解决方法

我能够通过以 root 身份运行 ldconfig 来解决这个特定错误。
