How do I write the 'cd' command in a makefile?

Question

For example, I have something like this in my makefile:

all:
     cd some_directory

Answer 1

What do you want it to do once it gets there? Each command is executed in a subshell, so the subshell changes directory, but the end result is that the next command is still in the current directory.

With GNU make, you can do something like:

BIN=/bin
foo:
    $(shell cd $(BIN); ls)
