Question

I am distributing my cpp files along with a makefile. Now the makefile is located in the same directory as the cpp file.

What is the variable (if any) in makefile that allows me to retrieve the current directory where the makefile is located? In this way I can use that variable to specify my cpp path for compilation.

My makefile is as follows:

all:
    g++ ($makeFileDir)/main.cpp ($makeFileDir)/hello.cpp ($makeFileDir)/factorial.cpp -o ($makeFileDir)/hello.exe

Edit: I am running my makefiles on Windows

I remember I had the exact same problem. It’s not possible, as far as I remember.
The best bet you can have is to pass it as a variable. That is both cross platform and guaranteed to work, as you know the makefile dir at invoke time (otherwise you can’t invoke it).

In alternative, you can do a very dirty trick, meaning you try to combine your current path (you can obtain with $(CURDIR) in gnu make) with the path of the invocation of the makefile (which can be tricky, and depends on your make)
