Custom make rules

[holychicken99]

Hi,
I am new to premake and had a doubt about custom rules for makefile generated by

premake5 gmake2

is there a way to add a custom rule which can later be invoked by saying

make {something}

is there a way to add a custom rule which can later be invoked by saying

No, that's not supported. The custom build rules are more like "when see files of type X, here are the build steps to apply to them", and are intended for things like shaders and DSLs. It sounds like you're asking for something more like a custom makefile target, which you can actually inject into your generated makefiles using makesettings().

Does that help?

hey , thx for the response !
I read the docs for makesettings and tried to do this

makesettings[[
    foo = ok

    all:
    ifeq ($(foo), ok)
        echo "foo equals ok"
    else
        echo "nope"
    endif
]]

this did not work as I was getting

==== Building output (debug) ====
output.make:34: *** missing separator.  Stop.
make: *** [Makefile:30: output] Error 2

also why does the shown example use [[ ]] ?

Thanks in advance !

Have you opened up the generated makefile and tried to investigate the issue at line 34? You probably shouldn't be defining an all: target since Premake has already create one for you, and makefile file targets should not be indented.

why does the shown example use [[ ]] ?

See String Tutorial on lua-users.org.

I have a test directory which contains a test.cpp file and I wanted to define a premake configuration such that the generated makefile
will let me write

make test 

and will then compile the test.cpp file. Thats why I was thinking of adding a custom target test. what should I do in this case ?
thank you

I'm pretty sure you can achieve make test using:

project "test"
  files { "tests/**.cpp" }

I've done it once before with a Premake generated makefile, so I could be wrong on exactly how it works but I'm pretty sure that's it.
