Change logging directory in Google glog

Question

How can I change the output directory in Google glog?

I only found google::SetLogDestination(google::LogSeverity, const char* path)

tried it with:

google::SetLogDestination(ERROR, "C:\\log\\error.log);
google::InitGoogleLogging("Test");  

LOG(ERROR) << "TEST";

but nothing was written!

Btw.: if you suggest another lightweight, easy to use and thread safe library please let me know!

Thx for any help!

You can also do one of the following:

Pass the log directory as a commandline argument as long as you have the GFlgas library installed:

./your_application --log_dir=/some/log/directory

If you don't want to pass it in the commandline and instead set it in the source:

FLAGS_log_dir = "/some/log/directory";

If the Google gflags library isn't installed you can set it as an environment variable:

GLOG_log_dir=/some/log/directory ./your_application
