SOLVED: Invalid option: +EX

I am setting up MPLab IDE v5.40 and ccs compiler v4.124 and I can't get my new project to compile.

I created a new project in MPLAB and used existing source and header files (which have been successfully compiled by others but I'm not sure their setup).

Every time I try to build the project I get an error in mplab and an external window from "pic c compiler" pops up saying: "Invalid Option: +EX"

MPLAB seems to be complaining about the make file. See error messages below:

"C:\Program Files (x86)\PICC\CCSC.exe" out=""build/default/production"" main.c +EXPORT +FH +DF +CC +EX +Y=9 +EA +DF +LN +T +A +M +J +Z -P \#__18F46K20=1 +EXPORTD="build/default/production"

BUILD FAILED (exit value 2, total time: 8s)

I have multiple source files in my build. Is that an issue? I've seen old posts about only being able to have the main file as the source code but I don't know if that still applies...

Any help would be greatly appreciated.

Note: I am running Windows 10 Home 64 bit

Normally the 'best' way, is to just have the single main project.c file,
and have this #include the rest of the files. The other files are added to
the 'header file' section of the project, and the one main file
is to only one put in the source file section.
It is technically possible to have the files compiled separately (which
means they can then be in the source file section), but they will all
have to be changed to have the main file #import the other files,
and have the other files all #export the functions and variables to
be passed to the main (look at 'multiple compilation units' in the manual.
However the 'traditional' way results in more efficient code, so honestly
use this.

And if you want to include the same .H files into those included .C files without error,

(if no one has mentioned yet)

Make sure to include this in every included H file (or similar)

Thanks for the info on multiple source files. I will read up on it!

Also, I contacted ccs tech support and they got back to me right away.
It turns out this is because I am using an older version of the compiler which doesn't have the +EX feature. So I either need to update my compiler or install an older version of the plugin for MPLAB.

Turns out my company does have a new version of the compiler but hasn't put it on our server yet. So I will install the newer version, test and post again to cofirm it's fixed the problem.

UPDATE
I installed the current version of ccs and made a new project, placed the existing files in it and was able to compile without any issues.
