In order to use the FindBugs annotations, you need to include annotations.jar and jsr305.jar from the FindBugs distribution on your classpath. If you are sure that you want the @SuppressFBWarnings annotation only (and not the others), then annotations.jar alone would be sufficient. You can find the two JARs in the lib folder of the FindBugs … Read more
Consider you have a module my_mod with a pub function my_func. You can’t use this function in your crate (or outside your crate) until you include your module using mod my_mod statement. After you include your module, you can use your function like that: mod my_mod; … my_mod::my_func(…) … You can’t use my_mod::my_func statement if … Read more
As you’ve already been told, it’s useful to read the manual – specifically this chapter – and even more specifically right here. Specifically, you want g++ -I/root/workingdirectory -I/root/workingdirectory2 Note also the documentation on #include directive syntax, described here as: 2.1 Include Syntax Both user and system header files are included using the preprocessing directive #include. … Read more
Yes, you have to include what you use. It’s not mandated that standard headers include one another (with a few exceptions IIRC). It might work now, but might fail on a different compiler. In your case, apparently <iostream> includes <string>, directly or indirectly, but don’t rely on it.
I had this same issue going from e.g gcc to visual studio for C programming. Make sure your include file is actually in the directory — not just shown in the VS project tree. For me in other languages copying into a folder in the project tree would indeed move the file in. With Visual … Read more
If the path to your headers is fixed in relation to your sources, then you should be able to avoid having to pass this info via the command line. Say your project’s directory structure is: /CMakeLists.txt /my_sources/main.cpp /my_sources/foo.cpp /my_includes/foo.hpp and in your CMakeLists.txt, you currently have something like: add_executable(MyExe my_sources/main.cpp my_sources/foo.cpp) then to add the … Read more
ssize_t is defined in sys/types.h. Per the POSIX documentation: NAME sys/types.h – data types SYNOPSIS #include <sys/types.h> DESCRIPTION The header shall define at least the following types: … ssize_t Used for a count of bytes or an error indication.
Logically, that copy/paste is exactly what happens. I’m afraid there isn’t any more to it. You don’t need the ;, though. Your specific example is covered by the spec, section 6.10.2 Source file inclusion, paragraph 3: A preprocessing directive of the form # include “q-char-sequence” new-line causes the replacement of that directive by the entire … Read more
