The rt lib seems to be missing, where can I obtain such lib to successfully compile 'system' lib? Changing bootstrap argument between gcc / mingw doesn't help. Before using bootstrap I set path to mingw using: > set PATH=c:\mingw\bin;%PATH% and change bootstrap.bat in line 38 to: > set toolset=gcc Any idea how to successfully compile system library under windows for QNX?"
