我的平台信息：
mips-linux
当我尝试在网页上"Print Test Page"时，它提示"stopped Filter failed"。然后我查看日志文件(/var/log/cups/error_log)，信息如下：

现在，我真的不知道如何找到这个问题的原因...
有什么想法吗？
谢谢，
艾伦
我已经解决了这个问题。
方法：
当我编译 cups-filter 时，我在 flag:CFLAGS、CXXFLAGS、CPPFLAGS 中指定参数“-Wl,--rpath=lib_path_in_run_board”。为什么需要指定三个标志？我必须确保 lib_path_in_run_board 编译到执行程序中。
还有一个问题让我很困惑。 liblcms2.so.2 存在于可用环境 LD_LIBRARY_PATH 的搜索目录中。我使用 LD_DEBUG=libs execute_program 调试可以看到它会搜索 LD_LIBRARY_PATH 中的目录并找到指定的库。为什么执行居然会报"error while loading shared libraries: liblcms2.so.2: cannot open shared object file: No such file or directory"。实在看不懂。
我今天解决了这个问题。
我的打印机是LENOVO_M2041_F2072_Series
我在 error_log 中发现的内容表明文件权限有问题。
因为我在日志中看到很多权限拒绝错误。
这是我的日志的一部分

我意识到 /Library/Printers/LENOVO/M2041_F2072/prefilter 或 /Library/Printers/LENOVO/M2041_F2072/rastertolenovo
的许可有些问题
所以我使用
切换到超级用户
sudo su
并更改了他们的权限
sh-3.2# chmod +x prefilter rastertolenovo
然后我再次点击打印，成功了！
我构建了 Cups-2.2.5，还构建了 cups-filter-1.17.8 及其所有依赖项。
我的平台信息： mips-linux
当我尝试在网页上"Print Test Page"时，它提示"stopped Filter failed"。然后我查看日志文件(/var/log/cups/error_log)，信息如下：

我可以看到信息 "error while loading shared libraries: liblcms2.so.2: cannot open shared object file: No such file or directory"。但是，这个库 "liblcms2.so.2" 存在于搜索目录中：

现在，我真的不知道如何找到这个问题的原因...
有什么想法吗？
谢谢， 艾伦
我已经解决了这个问题。
方法：
当我编译 cups-filter 时，我在 flag:CFLAGS、CXXFLAGS、CPPFLAGS 中指定参数“-Wl,--rpath=lib_path_in_run_board”。为什么需要指定三个标志？我必须确保 lib_path_in_run_board 编译到执行程序中。
还有一个问题让我很困惑。 liblcms2.so.2 存在于可用环境 LD_LIBRARY_PATH 的搜索目录中。我使用 LD_DEBUG=libs execute_program 调试可以看到它会搜索 LD_LIBRARY_PATH 中的目录并找到指定的库。为什么执行居然会报"error while loading shared libraries: liblcms2.so.2: cannot open shared object file: No such file or directory"。实在看不懂。
我今天解决了这个问题。
我的打印机是LENOVO_M2041_F2072_Series
我在 error_log 中发现的内容表明文件权限有问题。
因为我在日志中看到很多权限拒绝错误。
这是我的日志的一部分

我意识到 /Library/Printers/LENOVO/M2041_F2072/prefilter 或 /Library/Printers/LENOVO/M2041_F2072/rastertolenovo
所以我使用
切换到超级用户sudo su
并更改了他们的权限
sh-3.2# chmod +x prefilter rastertolenovo
然后我再次点击打印，成功了！
