  • why do you write tests and what is a unit test and how does it differ other types of testing ?

    - by dfafa
    im curious as to know, why tests are written? why would bother writing it ? why not just compile and run the code or view it in your browser, click around and test out stuff. i mean i can understand, a crawler that checks your web app's functions....but why is tests written, maintained and treated as important as the main feature codes ? is it crucial to always write and use tests ?

  • System loops using non-integers?

    - by mary
    I wrote a .sh file to compile and run a few programs for a homework assignment. I have a "for" loop in the script, but it won't work unless I use only integers: #!/bin/bash for (( i=10; i<=100000; i+=100)) do ./hw3_2_2 $i done The variable $i is an input for the program hw3_2_2, and I have non-integer values I'd like to use. How could I loop through running the code with a list of decimal numbers?

  • is it possible to load a shared library on a shared memory?

    - by quimm2003
    I have a server and a client written in C. I try to load a shared library in the server and then pass library function pointers to the client. This way I can change the library without have to compile the client. Because of every process has its own separate memory space, I wonder if it is possible to load a shared library on a shared memory, pass the function pointers and map the shared memory on the client and then make the client execute the code of the library loaded by the server.

  • Get column name in jpa

    - by German
    Hi all, I have a query factory that takes a column name as an attribute in order to search for that column. Right now I'm passing the name of the column as a string, so it's kind of hardcoded. If the name of the column changes in the entity's annotation, that "hidden dependency" breaks up. Is there a way in jpa to retrieve the real name of the column and have it available at compile time, so I can use it in queries?

I know that I should link the wchar library during compilation, but how do I do that?

  • Question on gcc compiler commands

    - by user271916
    I had to compile a small little C program using the following; gcc sine.c -o sine -lm I needed the "-lm" because the program included the math.h. In looking this up under compiler commands man shows it a either -llibrary or -l library. I could not find any information on what other libraries. Apparently -lm is needed for math.h what other library commands might be needed. Thanks

  • Is there a way to suppress warnings in Xcode?

    - by kdbdallas
    Is there a way to suppress warnings in Xcode? For example I am calling an undocumented method and since the method is not in the header I get a warning on compile. I know I can add it to my header to stop the warning, but I am wondering if there is a way other then adding it to the header (so I can keep the headers clean and standard) to suppress the warning? A pragma or something?

  • Convert an array of primitive longs into a List of Longs

    - by CaptainAwesomePants
    This may be a bit of an easy, headesk sort of question, but my first attempt surprisingly completely failed to work. I wanted to take an array of primitive longs and turn it into a list, which I attempted to do like this: long[] input = someAPI.getSomeLongs(); List<Long> = Arrays.asList(input); //Total failure to even compile! What's the right way to do this?

  • What binary architectures should be cross-compiled when building Mac OS X packages?

    - by Alex Leach
    Currently, Apple's native binaries and libraries are distributed as fat files, with support for both i386 and x86_64 architectures. The SDK (Xcode 4.4 w/ command line tools) doesn't support cross-compiling powerpc binaries any more, so they can be safely ignored I think, but there doesn't seem to be any specific guidelines or recommendations about which Intel architectures to support. So, when compiling code for distribution on OS X, do people still cross-compile for the i386 architecture? Or are x86_64 binaries the only architecture worth bothering with nowadays?
