like the idea or not ;-) THE IDEA: The idea is to make GCC better when it comes to gcc error message format error reporting. This will be done using so called error codes which then can be looked up in a properly formatted document to see what the error means when in confusion. This

will save time when it comes to searching what a error means around and improve usability. ERROR CODE FORMAT: The way errors are shown is as follow: for example instead of: "ISO C forbids specifying range of elements to initialize" you get: "c742: ISO C forbids specifying range of elements to initialize" Note that this error code is random i want to avoid this by strerror a numbering system as follows: The numbering starts from x100 and goes on from there, there will be no particular error code pattern because its to late for that rather it will start with warning() in alphabetic order of the source file names. so in a file called aaa.c the first warning will be x100 and then the second warning x101 until all warnings are numbered the next source file gets numbered. The order is: warning() error() pedwarn() (and pedwarn_c99()) From there on if warning or errors are added the numbering goes up so it wont be arranged anymore. The `x' prefix will indicate what language for C++ specif errors/warning it should differ from the C prefix. ERROR CODE DOCUMENT: To document error codes there needs to a be a format. It will look very familiar for those who have been reading/making man pages as well ;-) These are the sections: *ERROR Code of the error. *DESCRIPTION Describe the error. *EXAMPLES Show a pseudo-code example on how you should not do it but how to do it instead. (if needed) *SEE ALSO Show error codes that looks similar. *SUPPORT If t

are one of three types: Compiler Errors Linker Errors Run Time Errors lets examine these three types of errors in einprogress more detail. Compiler Errors Compiler errors are caused by incorrect syntax. This means that you have not followed the basic rules of C. These basic rules are things like: putting a https://gcc.gnu.org/ml/gcc/2006-01/msg00419.html semicolon at the end of a line writing a proper function header passing the correct number and type of arguments to a function matching up all pairs of braces {} and parentheses () not using variables that you haven't declared declaring all variables at the top of a function many, many more When you run the compiler on your code it first does any preprocessing (that http://web.ics.purdue.edu/~cs240/misc/errors.html is any line that begins with #). Then it checks the syntax of your code. In other words it makes sure that you have followed all the rules of C. If you haven't it prints out an error so that you can fix your syntax. Unfortunately most new users find the messages sent back from gcc confusing. So we will go over some common gcc error messages, what they mean, and how to fix them. General compile-time error and warning description In C, a compilation error is usually fatal, meaning that the C compiler cannot compile the source code. A warning, on the other had, is usually just that. The compiler has identified that there may be a problem, but it can produce object code anyway. Warnings should not be ignored, because they usually do indicate that there is something wrong with the program, and it is likely to behave differently from what you would expect. Error messages and warnings are preceded by the program file name and function in which the error was encountered. For example, prog.c: In function `main': indicates that the error was encountered in the program file prog.c, and specifically in func

If I've missed anything in the conversion process, please tell. Sometimes GCC emits something that can be described as Haiku poems - and you have no clue as to what it really is complaining about.

I downloaded the 3rd download on this page: http://www.codeblocks.org/downloads/26#windows .Thank you. « Last Edit: January 04, 2013, 08:05:11 pm by pb910 » Logged laYahooz Single posting newcomer Posts: 2 Re: can't find compiler executable in your search path (GNU GCC compiler) « Reply #1 on: January 04, 2013, 11:06:00 pm » I had a similar problem. Please note I'm a total n00b in C++ and IDE's but heres what I did (after some research)So of course I downloaded the version that came with the compiler and it didn't work. Heres what I did:1) go to settings in the upper part2) click compiler3) choose reset to defaults.Hopefully this works Logged pb910 Single posting newcomer Posts: 2 Re: can't find compiler executable in your search path (GNU GCC compiler) « Reply #2 on: January 06, 2013, 12:56:37 am » yes that worked, thanks Logged blahzay Single posting newcomer Posts: 1 Re: can't find compiler executable in your search path (GNU GCC compiler) « Reply #3 on: March 29, 2013, 03:53:25 pm » yes thanks, that worked for me too.
