You’re missing the log4j.properties or log4j.xml in your classpath. You can bypass this by using BasicConfigurator.configure(); But beware this will ONLY log to System.out and is not recommended. You should really use one of the files above and write to a log file. A very simple example of log4j.properties would be #Log to Console as … Read more
Why is this a narrowing conversion? Because the definition includes (with my emphasis): C++11 8.5.4/7 A narrowing conversion is an implicit conversion […] from an integer type […] to a floating-point type, except where the source is a constant expression and the actual value after conversion will fit into the target type and will produce … Read more
If you want to turn it on (or off) in the project setting, you have to go to: Configuration Properties -> C/C++ -> Command Line and then under Additional Options you can enter: /w3#### to set your warning to level 3, and thus enable it; or you can enter /wd#### to disable a warning. Current … Read more
You need to set$final[$id] to an array before adding elements to it. Intiialize it with either $final[$id] = array(); $final[$id][0] = 3; $final[$id][‘link’] = “https://stackoverflow.com/”.$row[‘permalink’]; $final[$id][‘title’] = $row[‘title’]; or $final[$id] = array(0 => 3); $final[$id][‘link’] = “https://stackoverflow.com/”.$row[‘permalink’]; $final[$id][‘title’] = $row[‘title’];
For warnings to be “flagged” to PHP natively would require changes to the mysql/mysqli driver, which is obviously beyond the scope of this question. Instead you’re going to have to basically check every query you make on the database for warnings: $warningCountResult = mysql_query(“SELECT @@warning_count”); if ($warningCountResult) { $warningCount = mysql_fetch_row($warningCountResult ); if ($warningCount[0] > … Read more
In this case the compiler detects that s is written but not read, and deliberately suppresses the warning. The reason is because C# is a garbage-collected language, believe it or not. How do you figure that? Well, consider the following. You have a program which calls a method DoIt() that returns a string. You do … Read more
GCC does warn about this. But you need to do two things: Enable optimization. Without at least -O2, GCC is not doing enough analysis to know what a is, and that you ran off the edge. Change your example so that a[] is actually used, otherwise GCC generates a no-op program and has completely discarded … Read more
This should do the trick: #pragma warning (error: 4715). Or the /we4715 command line option (see /w, /W0, /W1, /W2, /W3, /W4, /w1, /w2, /w3, /w4, /Wall, /wd, /we, /wo, /Wv, /WX (Warning Level) (courtesy of Tom Sigerdas)).
If you really, really must do this, and you are sure you are not making a mistake, check out the @SuppressWarnings annotation. I suppose in your case you need @SuppressWarnings(“fallthrough”) Is the annotation @SuppressWarnings (javadoc) what you are looking for? For example: @SuppressWarnings(“unchecked”) public void someMethod(…) { … }
To silence warnings you have to add the allow(warning_type) attribute to the affected expression or any of its parents. If you only want to silence the warning on one specific expression, you can add the attribute to that expression/statement: fn main() { #[allow(unused_variables)] let not_used = 27; #[allow(path_statements)] std::io::stdin; println!(“hi!”); } However, the feature of … Read more
