freshclam：符號查找錯誤：freshclam：未定義符號：print_version，版本 FRESHCLAM_PRIVATE

Question

我按照本指南在 Ubuntu 20.04 LTS 上從源代碼安裝 clamav，但在收到以下錯誤后我停止了： freshclam: symbol lookup error: freshclam: undefined symbol: print_version, version FRESHCLAM_PRIVATE 。 以下是我發出的命令：

./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，我剛剛在 Example 之前添加了 # 以將其注釋掉。 然后：

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

這個錯誤是什么意思？

以下是 ./configure --enable-check 和 make check 的輸出：

./configure --enable-check

PS 這不是我第一次嘗試在此計算機上安裝 clamav。 我第一次沒有這個錯誤，但后來我在執行sudo make uninstall以完全刪除 clamav 文件並從頭開始安裝后手動刪除了一些文件。 我還刪除了 clamav 用戶和組，現在它們似乎不再自動創建，我想知道為什么。

我能夠通過以 root 身份運行ldconfig來解決這個特定錯誤。
