Is there a readme that tells what packages must be installed? Can't build on windows.

this got me closer: mingw-w64-x86_64-libusb-compat-git
this was a help: mingw-w64-x86_64-pkg-config
adding this the the makefile seemed to help, but was probably a mistake: PKG_CONFIG_PATH ?= ./src/sdr

I now get this error:

Package librtlsdr was not found in the pkg-config search path.
Perhaps you should add the directory containing `librtlsdr.pc'
to the PKG_CONFIG_PATH environment variable
No package 'librtlsdr' found

@dizzisound might have some insights on the Windows platform.

If we wanted to add general build instructions, we should include the Mac/Linux environment setup from the .travis.yml

@squinkylabs Hi, I can try to recover what worked for me. After some unsatisfactory trials at linking precompiled dependencies, I chose to install and build the required dependencies from source. For what I remember (I wrote down only some quick notes), I used the following cli command sets.

1. For libusb:

$ cd ~
$ git clone https://github.com/libusb/libusb.git
$ cd libusb
$ ./autogen.sh
$ make && make install

2. For librtlsdr:

$ cd ~
$ git clone git://git.osmocom.org/rtl-sdr.git
$ mkdir rtl-sdr/build && cd rtl-sdr/build
$ cmake -G "MSYS Makefiles" -D LIBUSB_FOUND=1 -D LIBUSB_INCLUDE_DIR=/mingw64/include/libusb-1.0 -D "LIBUSB_LIBRARIES=-L/mingw64/lib -llibusb-1.0" -D THREADS_PTHREADS_WIN32_LIBRARY=/mingw64/x86_64-w64-mingw32/lib/libpthread.a -D THREADS_PTHREADS_INCLUDE_DIR=/mingw64/x86_64-w64-mingw32/include -D CMAKE_INSTALL_PREFIX=/mingw64 ..
$ make && make install

Here a bunch of my sensible env vars:

MSYSTEM=MINGW64
MSYSTEM_CHOST=x86_64-w64-mingw32
MSYSTEM_PREFIX=/mingw64
MINGW_CHOST=x86_64-w64-mingw32
MINGW_PREFIX=/mingw64
MINGW_PACKAGE_PREFIX=mingw-w64-x86_64

That's all, then the makefile shared with Jon worked for me together with the latest Rack sourcecode.
Hope it's all correct and it can works for you.

@dizzisound thanks for that info - I want to move towards building dependencies in the makefile on all platforms #31

[squinkylabs]

tx for the info!

@wizardishungry Also could this be of some interest? https://github.com/FPGAwars/libusb-cross-builder
