问题 I am just trying to compile some simple example code I typed in from a book, and GCC gives me the above error.

iOS - How to view NSLog and printf output in ssh session on phone?

阅读更多关于 iOS - How to view NSLog and printf output in ssh session on phone?

问题 I have a simple iPhone App that uses an NSLog and several printf statements. The app is a simple test app that I created to test serial communication on the iPhone (3GS). Obviously I can not test serial com with the iOS Simulator, so I have my device unplugged from the computer after I click Run from within Xcode. I installed syslogd from Cydia, and tail /var/log/syslog allows me to monitor certain log messages. However when I open my app and it reaches the NSLog portion of the code I don't

Python's SyslogHandler and TCP

阅读更多关于 Python's SyslogHandler and TCP

问题 I'm trying to understand why the SyslogHandler class from Python's logging framework (logging.handlers) does not implement any of the framing mechanism described by RFC 6587: Octet Counting : it "prepends" the message length to the syslog frame: Non-Transparent-Framing : a trailer character to separate messages. This is what most of the servers understand. This "problem" can be easily solved by adding a LF character to the end of the messages, however I would expect that the SyslogHandler

how to parse syslog timestamp

阅读更多关于 how to parse syslog timestamp

问题 http://www.syslog.cc/ietf/drafts/draft-ietf-syslog-protocol-23.txt 6.2.3.1. Examples in the above link provides examples of different timestamp formates. How can I parse these timestamps in C ? On-the-fly, any type of message can arrive and I want to be able to parse it. 回答1: The date format is a stricter version of RFC3339 giving a string such as '2011-08-18T23:31:42Z' I'm not certain the strptime function can deal with the timezone specifier (Z in the time string above), so it may be easier

Glassfish to Syslog

阅读更多关于 Glassfish to Syslog

I'm struggling to make Glassfish 3.1.1 to log to syslog, but I'm unable to. I don't know if it's a bug, but I don't even know how to debug it. First and obvious step: I checked the box on the administration console to write to system log, and after I also marked the checkbox write to system console. None of them worked. I checked the logging.properties and this line is there com.sun.enterprise.server.logging.SyslogHandler.useSystemLogging=true Googling I found a few people complaining with abandoned questions. Is there anything else I should do or I have to write a custom log handler to do

Using Syslog's unix socket with Log4J2

阅读更多关于 Using Syslog's unix socket with Log4J2

问题 I would like to send the logs of an application on a rsyslog server using the client protocol : Unix socket. Both application and rsyslog server are on the same machine. I've been comparing different logging tools : Log4J, Logback and Log4J2. Log4J's Syslog appender doesn't permit it natively. A solution is to use Syslog4J and configure our Syslog4JAppender this way : <appender name="mySyslogAppender" class="org.productivity.java.syslog4j.impl.log4j.Syslog4jAppender"> <param name="protocol"

How can I use `syslog` in Swift

阅读更多关于 How can I use `syslog` in Swift

Looks like syslog() function is not available in Swift 2. How can I send a message to syslog on OS X? The problem is that void syslog(int priority, const char *message, ...); takes a variable argument list and is not imported to Swift. You can use void vsyslog(int priority, const char *message, va_list args); instead and define a wrapper function in Swift: func syslog(priority : Int32, _ message : String, _ args : CVarArgType...) { withVaList(args) { vsyslog(priority, message, $0) } } syslog(LOG_ERR, "i=%ld, x=%f", 123, 34.56) Note that string arguments have to be passed as C strings: syslog

What is the most modern way to log to syslog using a java.util.logging handler?

阅读更多关于 What is the most modern way to log to syslog using a java.util.logging handler?

问题 I am specifically looking for the most up to date, modern SysLogHandler for java.util.logging . I have found a few that date back to 2001 - 2003, mostly un-supported now. I know that syslog is a pretty static service, I am wondering before I write something myself, if there are any newer handler implementations that support the Java 1.5 and newer features. I am not interested in any of the other logging frameworks or wrapper / proxy libraries. I am not looking for SLF4J or any other
