EXTERNal symbol not found flash_led

[Mike Jennings]

Hi,

Something really strange is happening. Last week I had successfully compiled and run my code but today I get an "EXTERNal symbol not found flash_led" but have no idea why.

Nothing in the code has changed since I last successfully compiled.

The function flash_led comes after the main function and has a function prototype at the tope of the file and is in the same file as main which calls it. There are no other calles to this function from any other file.

What it happening????

The compiler version is PCWH 3.238


I would greatly appreciate if anyone can offer any suggestions or reasons.


Thanks

The "EXTERNal symbol not found flash_led" is the actual error the compiler throws up; flash_led is one of my functions within my code.

My spelling is not great but there are no other colpiler errors and the code is currently working. However, I require to make a change but when trying to recompile without changing anything I got this error.

One this that has changed is that I on a new PC and have therefore reinstalled the PCWH software which had been updated but have rolled back to 3.238 as I no longer have support agreement.


Thanks

Can you post a small test program that shows the problem ?
Strip down the program so that it only contains the flash_led()
function, and the prototype, and the code to call it in main().
In other words, strip it down to the smallest possible program
that will still show the problem. Also post the #include and
#fuses statements so the program can be pasted into MPLAB
and will compile without errors. If you can do this, we can
probably find the problem. I have PCH vs. 3.238 and can
install it to check the problem.

I have found the problem, I had an external reference to led_flash in another file where of the project where I used a call to led_flash for testing purposes. I failed to remove the external prototype definition after I removed the calls.

The PCWH search feature failed to find it. It was when I did a search using windows file explorer that it appeared.

It is still strange that this code was in there for a good few compiles before it decided to throw the error.

Anyway, thanks for your interest and offer of assistance.

thanks for the speedy reply...
i've only one source file.. no other file is present.. is it ok if i don give the extern key word??

the problem is with prototype declaration of a variable,, its declared as extern byte s[12]
it compiles properly if i remove that extern key word.. so is it ok if i don use that key word???
