The example files helped a ton, got it to compile now.

Planning on messing with macroing within the sequencer as well, is the easiest way to just set some env variables in envPaths file that I load in the st.cmd?

Hi Adam, 

 

The sequencer’s build rules run each .st file through the C Preprocessor (generating the .i file which you’ll see in the O.<arch> directory) before compiling the result to a .c file, so you can use #include statements to pull the sources of other files into the .st that you ask the build system to compile. The result must of course be syntactically correct and you’ll need to be careful to not re-use the same global variable names in different sequences, but you should be able to split up your existing large file quite easily using that.

 

The makeBaseApp example uses that to compile the sncProgram.st file, although that is to generate a stand-alone executable so the Makefile entries will look slightly different.

 

HTH,

Hey All,

 

Is it possible to have multiple .st files and compile them together similar to #include in C and compiling the multiple .c files?  I couldn’t find anything explicit in the documentation, only that I could add in the SRCS += *.st files in the Makefile but I think this only compiles each st file separately?  My Goal is to separate out the multiple sequencers that I have currently in a large .st file.

 

Thanks,

Adam
