Re: Compiling .c code using mkoctfile

[Colin Kikuchi]

Hey Carlo, 

Thank you for your response! I tried compiling to an mex file based on the link you sent, using "mkoctfile --mex mexADIconf.c", but got the same error. I am attaching an example of the code I am trying to compile (there are several other programs like this one) in hopes that you or someone else might be able to give me a tip about compiling into an octfile. Sorry, I am a bit inexperienced with Octave so would really appreciate any suggestions you might have!

Thanks again!

-Colin

This #include statement is meant for C++ not C.

Octave libraries are in C++, not C, so you cannot include their headers in your C code and compile with a C compiler.
Depending on what you want to do, you can either

* compile your C code with a C++ compiler (the easiest way to do so is  to rename it to .cc instead of .c)

* access Octave libraries via the mex interface (which is a Matlab compatible C API) as explained here : https://octave.org/doc/interpreter/Mex_002dFiles.html#Mex_002dFiles

Hope this helps, if you need more in-depth help you should provide more info, or share the .c code you are trying to compile.
