Paste the command in the Makefile directly to the command line and see what gcc says. Note that you might not be able to select your environment. If it’s from Linux, you might need to use a real Linux or WSL. The following commands are in the context of the makefile that follows. I hadn’t tried either, so I figured this would be a good excuse to learn.

Simple suffix rules work well as long as the source files do not depend on each other and on other files such as header files. Another route to simplify the build process is to use so-called pattern matching rules that can be combined with compiler-assisted dependency generation. As a final example requiring the gcc compiler and GNU Make, here is a generic makefile that compiles all C files in a folder to the corresponding object files and then links them to the final executable. Before compilation takes place, dependencies are gathered in makefile-friendly format into a hidden file “.depend” that is then included to the makefile.
Note that this won’t propagate to sub-makes automatically. Can I pass variables to a GNU Makefile as command line arguments? In other words, I want to pass some arguments which will eventually become variables in the Makefile.

Portable programs ought to avoid constructs used below. The Makefile (input for make) contains a Forest Arrow Casino set of targets. Each target has a set of dependencies (on other targets) and rules how to build the target. Make reads the Makefile(s) and manages all targets, dependencies, and build rules.
This will make your yourLocalBranchName track the remote branch called develop. Since a thread that does disk operations is technically almost idle from CPU point of view, add one to the total number of cores. So in order to attack the problem, the error message from gcc is required.
I know its a little late but other people with similar problem might get some help. From GNU Make error appendix, as you see this is not a Make error but an error coming from gcc. In the former Makefile, a is not evaluated until it’s used elsewhere in the Makefile, while in the latter a is evaluated immediately even though it’s not used. There isn’t any need to install Chocolatey (executable choco) anymore. On Windows 10 or Windows 11, you can run the command winget install ezwinports.make in the command line or PowerShell to quickly install it, restart the command line or PowerShell.
Examples of built-in implicit rules that use CPPFLAGS
Git branch -u–set-upstream-to has been introduced with a saner order of arguments. As you say the -j flag tells make that it is allowed to spawn the provided amount of ‘threads’. Ideally each thread is executed on its own core/CPU, so your multi-core/CPU environment is used to its fullest.
Every environment variable that make sees when it starts up is transformed into a make variable with the same name and value. However, an explicit assignment in the makefile, or with a command argument, overrides the environment. Makefiles can access predefined internal macros, with ? In addition to referring to the original Unix tool, Make is also a technology since multiple tools have been implemented with roughly the same functionality – including similar makefile syntax and semantics. If you set the allowed number of threads too high, it is not possible to schedule each thread on its own core.
