Gcc Compiler Error List

Contents

These can often be more frustrating because they aren't necessarily the result of something written in your program. Generally, you can set the warning level of your compiler--I like to keep it at its highest level so that my compiler warnings don't turn in to bugs in the running There are two pieces of good news though. For instance, even if you include the correct header files for all of your functions, you still need to provide your linker with the correct path to the library that has http://blogeurope.net/gcc-error/gcc-error-list.php

Gcc Error Message Format

Example: #include int main (void) { printf ('Hello World!\n'); /* wrong quotes */ return 0; } The program above confuses single-quotes and double-quotes. Nevertheless, compiler warnings aren't going to stop you from getting your program working (unless you tell your compiler to treat warnings as errors), so they're probably a bit less frustrating than Fortunately, it's pretty clear that the function definition for foo was OK; this tells us that the error must have been caused somewhere else in the program. Linker Errors Once you've finally cleaned up all those frustrating syntax errors, taken a nap, had a meal or two, and mentally prepared yourself for the program to build correctly, you
