how to write a makefile for c program multiple files

gcc -std=c99 -o go go.c neuron.c -lm #include #include #include #include 'neuron.Compiling the source code files can be tiring, especially when you have to include several source files and type the compiling command every time you need to compile. Here is our main program which is called go.c: This calculation, and that the code is stored in a file called Provided us with) a C function called compute_PD() that performs Imagine for the moment that we have already written (or someone has The details of how theseĬomputations are done are not so important to consider here, but

Is, the direction of movement for which the neuron fires mostĮnthusiastically (most spikes per second). Per second averaged over a window starting 150ms before movement onsetįor each neuron, the goal is to compute a preferred direction. Velocity vector at peak hand velocity), and second, another array ofĤ0 values that indicate for each movement, the mean number of spikes Of the movement (specifically, the direction, in radians of the The data for each neuron are represented by two sets of values: first,Īn array of 40 values that indicate for each movement, the direction Movements to each of theĨ targets were repeated 5 times for a total of 40 movements. Targets around the circumference of a circle. Moved his hand from a central start target to one of 8 peripheral Recorded in primary motor cortex of rhesus macaques, during a Here is a program that computes the preferred direction of a neuron Place, and you don't have to go searching through all of your You find and fix an error) that you only have to change it in one It also means that if you everĭecide to change one of those re-usable functions (for example if WhenĬompiled, it's just like copying and pasting the code above main(),īut for the purpose of editing and writing your code, this allows you Incorporate into your C programs is to place them in their own file,Īnd to include a statement above main() to include that file. A better way to re-use functions that you commonly Your main source file, above the declaration of the main()įunction. We saw in the section on functions, that one way of includingĬustom-written functions in your C code, is to simply place them in Will see how to place C functions and data structures in their ownįile(s) and how to incorporate them into a new program. Re-use in your own scientific programming and data analysis. Your own library of C functions and data structures, that you can other C libraries) you will have toĭeal with code that resides in multiple files. As your programs become larger, and as you start to deal

The programs we have seen so far have all been stored in a single
