Let's add a few more phony targets: generate and clean to the Makefile :. That's because only the first target in the makefile is the default target. Often called the default goal , this is the reason you will see all as the first target in most projects. It is the responsibility of all to call other targets. We can override this behavior using a special phony target called.
As the name suggests, the phony target. This is why most makefiles include all as a target that can call as many targets as needed. Before running make , let's include another special phony target,. PHONY , where we define all the targets that are not files. Here is the complete makefile:. It is a good practice not to call clean in all or put it as the first target.
Now that you have an idea of how a basic makefile works and how to write a simple makefile, let's look at some more advanced examples. Our latest Linux articles In the above example, most target and prerequisite values are hard-coded, but in real projects, these are replaced with variables and patterns.
For example, to assign the command gcc to a variable CC :. This is also called a recursive expanded variable , and it is used in a rule as shown below:.
But if one tries to reassign a variable to itself, it will cause an infinite loop. Let's verify this:. We should have no problem running the makefile below:. The following makefile can compile all C programs by using variables, patterns, and functions. Let's explore it line by line:. In this case, all files with the. In this case, if SRCS has values 'foo. Let's look at an example to understand this rule. Below is the rule in its expanded form:. Every prerequisite in the previous rule is considered a target for this rule.
Below is the rewrite of the above makefile, assuming it is placed in the directory having a single file foo. For more on makefiles, refer to the GNU Make manual , which offers a complete reference and examples. You can also read our Introduction to GNU Autotools to learn how to automate the generation of a makefile for your coding project.
An example makefile for Windows seems that nmake on Windows ignores the bash script shebang top line, so I left it in :. Then I change a few items for the Linux makefile. Change the compile options, change the object file extension to ". It is certainly possible to add more source files for a larger project. The makefile could use subdirectories to organize the object files and take advantage of declaring more variables to define directories and other options, but I've left that out for this example.
Does the example. How many source files do you have, and would more automated parsing of the. Thanks Greg for posting this. It is nice to have this for reference. Something like this belongs in a How To Hi Jim, Thanks for the encouragement. I could post to Stackoverflow too, perhaps adding the source files to give a more complete example. The area. Great thanks for your support. The lessons learnt are:. F90 files in the proper order! This lists sets the order of.
F90 files compilation and linking again, I am not make expert. F90 and. F files. F files and prints out sth like this:. I will apply this concept to my real project I have about F files in various locations, module-submodule dependencies, including external libraries, etc..
If I have further thoughts I will definitely comment here. I'm glad to hear you're making progress with your make file. If you have source files in a project it will be worthwhile to automate the text parsing of the. January 28, at PM.
In both cases, however, I am unable to build a platform in Vitis. If I grab the xsa file and copy it over to my linux environment, I can repeat the process in Vitis and the platform compiles without error. I don't know for sure if the HLS origins has anything to do with the failure, but it's possible. All Answers. Hi, I encountered the sam problem, but the problem is leading tab character before ' ', in comment line. I just deleted leading tab character in mentioned lines with echo VitisHLS Hi jerhillhil7 If the code is working in Linux and not in windows, then this is possibly an issue with the path the files are located in.
I have the identical error. Which only appears in vitis Update Platform works, the problem is when building the platform. Attached you can find the make file that creates the trouble. I created the same ip core with HLS The make files look completly different.
In my case, it throws the error at line 40 or 41?
