Configurable output

The build products seem to go in a weird (to me place). I'd like libraries, executables to just be output in the directory where the makefile/product is defined. I'm not clear on how to achieve this.

c3d commented

The simplest way would be to use make OBJROOT=$(PWD). Or if you want something that is slightly more encapsulated, use something like make OBJROOT=$(PWD)/.build.

In general, if you want the build output to go to /some/specific/path, you can use make OBJROOT=/some/specific/path. Note that the path must be absolute, relative paths won't work well if you have libraries.

Also note that if you want to preserve a per-target structure, you can use BUILD_OBJECTS instead of OBJROOT.

With make OBJROOT=$(PWD)/.build, the .build directory looks like:

With make BUILD_OBJECTS=$(PWD)/.build, there will be an additional macosx-clang/opt path so that builds for different values of BUILDENV and different targets will go at different places:

I close this topic for now, but please feel free to reopen if you think there would be a better way to do it. Thanks for your comments.

Sorry, what I want is ONLY the EXECUTABLES to go in some directory I specify.
If I want someone to check out my code from github, build it, and run an executable, I want the executable to be in some handy top-level directory or the root directory itself. They don't care about the object files or digging through the strange and unpredictable

.build/
└── macosx-clang
    └── opt
        ├── build

directory structure. They just want to run the freaking binary.
