Hello ALSA-devel team, nice to contact you. Firstly I want to let you know I'm a fan of the work of you guys of the ALSA Project, specifically of the alsa-lib of which I had a little experience. I'm needing help with the compile of the alsa-lib library, I'm using cygwin and following the instructions in the "INSTALL" file inside the source but during the compiling with the command "./gitcompile" I'm getting some errors, here the entire log:
