hplip/hpcups “libImageProcessor.so：無法打開共享對象文件：沒有這樣的文件或目錄”

我有 Debian 10 系統和 HP OfficeJet Pro 8020 列印機。Debian 10 不包含此型號的驅動程序。HP 提供64 位 Debian 的手動升級說明… Debian 版本 6。

您需要首先安裝的某些軟體包可能已更改名稱。我主要作弊 - 我使用apt build-dep hplip, 從舊的 Debian 版本中獲取所有建構依賴項。

建構成功。我現在可以看到特定列印機的驅動程序，並且可以在 CUPS 中進行設置。我的問題是它無法列印任何東西。

/var/log/cups/error_log包含這一行：

令人困惑的是，有時順序會發生變化，因此首先列印“stopped with status 127”。更令人困惑的是，在此錯誤之後還有更多日誌消息。其中之一是“斷管”，就好像 CUPS 設置了一個程序管道，當 hpcups 死亡時，所有程序都會崩潰。

我確認這是庫路徑的問題：

$ ldd /usr/lib/cups/filter/hpcups | grep libImageProcessor
   libImageProcessor.so => not found

請注意手冊說明中的此步驟：

./configure --with-hpppddir=/usr/share/ppd/HP --libdir=/usr/lib64 --prefix=/usr --enable-qt4 --disable-libusb01_build --enable-doc-build --disable-cups-ppd-install --disable-foomatic-drv-install --disable-foomatic-ppd-install --disable-hpijs-install --disable-udev_sysfs_rules --disable-policykit --enable-cups-drv-install --enable-hpcups-install --enable-network-build --enable-dbus-build --enable-scan-build --enable-fax-build

中只有幾個文件/usr/lib64/，除了一個之外，所有文件都是由 hplip 安裝的。Debian 10 上正確的庫路徑是/usr/lib/x86_64-linux-gnu/. 如果您已經使用錯誤的路徑建構，請執行make clean. 然後，更改說明以改用此配置命令：

./configure --with-hpppddir=/usr/share/ppd/HP --libdir=/usr/lib/x86_64-linux-gnu --prefix=/usr --enable-qt4 --disable-libusb01_build --enable-doc-build --disable-cups-ppd-install --disable-foomatic-drv-install --disable-foomatic-ppd-install --disable-hpijs-install --disable-udev_sysfs_rules --disable-policykit --enable-cups-drv-install --enable-hpcups-install --enable-network-build --enable-dbus-build --enable-scan-build --enable-fax-build
