Hello! Haven't talked for a while... I am currently involved with Tizen OS and my dream is to get its build system running on Cygwin. The whole thing is based on RPM, so i had to do some upgrades to our RPM port. I took 4.12 version, v5 appeared to be too problematic. Download URL is: http://nashdisk.ru/bc3d24/ . The site is in Russian, sorry for that, just press the green button in order to get a single TAR file. All packages (64-bit) are inside. Of course before uploading to Cygwin i'll rebuild the 32-bit version too.
I have tested this version, even built some packages. Seems to work OK. This version even works for installing root filesystem packages into a dedicated sysroot. I had to do some improvements to unpacking algorithm in order to make this possible. Also i have enabled Python API, which is necessary for running gbs.
