怎么启用scim的全部打印？

[hantengc]

ubuntu 2004系统
操作步骤：

1. 终端执行 scim ，查看日志打印信息
2. 发现在scim_module_init里面的stderr信息都有输出到终端上
3. 发现scim的engine里面日志信息没有被输出在终端上
4. 当前存在的进程：scim-launcher、scim-helper-manager、scim-panel-gtk和scim-im-agent这几个进程
5. 查看进程的fd文件发现也没有任何的日志输出：sudo tail -f /proc/pid/fd/2 或者sudo tail -f /proc/pid/fd/1或者sudo tail -f /proc/pid/fd/0 都是没有任何输出的。代码里面使用的打印方式是： SCIM_DEBUG_IMENGINE(2) << "engine debug info \n"

请问我应该怎么设置debug输出等级，将打印信息输出呢？

You may build the scim with debug enabled and specify the debug flag to see if your module is loaded correctly.

how to build the scim with debug enabled?

You may configure the scim with --enable-debug to enable the debug facility support.

$ ./configure --help | grep debug
  --enable-debug          Turn on debugging

构建的时候执行的命令是：./configure --prefix=/opt/scim --enable-debug --enable-clutter-immodule
并且log信息显示我已经启用了debug
我在终端执行./scim并没有任何有用的日志输出，请问我应该怎么运行scim才可以看到里面所有的log？

You may specify the -m (or --mask) and -v (or --verbose) flags to specify the debugging module and level.
For example, scim -v 7 -m all
