The stripped exe debug info is saved as part of each cygport build and supplied as part of the binary -debuginfo package, if available, under /usr/lib/debug/usr/.../*.exe.dbg. With recent cygport releases I believe everything is taken care of unless you override (or mess up, or don't use) the cygport build and upload defaults. If I want to try a package, I grab the sources from upstream, copy and modify a cygport file to do the build, as it makes it so easy to use a variety of tool chains I am unfamiliar with, and gdb if required for diagnosis. $ apt-cyg listfiles cygwin-debuginfo | fgrep .dbg usr/lib/debug/usr/bin/cygwin1.dbg usr/lib/debug/usr/bin/chattr.exe.dbg usr/lib/debug/usr/bin/cygpath.exe.dbg ... usr/lib/debug/usr/bin/cygwin-console-helper.exe.dbg usr/lib/debug/usr/bin/ldh.exe.dbg usr/lib/debug/usr/bin/strace.exe.dbg usr/lib/debug/usr/sbin/cygserver.exe.dbg $ apt-cyg listfiles coreutils-debuginfo | fgrep .dbg usr/lib/debug/usr/bin/arch.exe.dbg usr/lib/debug/usr/bin/b2sum.exe.dbg usr/lib/debug/usr/bin/base32.exe.dbg ... usr/lib/debug/usr/bin/whoami.exe.dbg usr/lib/debug/usr/bin/yes.exe.dbg usr/lib/debug/usr/bin/[.exe.dbg usr/lib/debug/usr/libexec/coreutils/libstdbuf.so.dbg $ -- Take care.
