[PD-dev] Compiling debug mode for GDB on MSYS2 MINGW64

[Christof Ressi]

Hi,

yes, "make app" strips the binaries by default.

Since autotools/libtool is incredibly slow on Windows, I typically only 
do "make app" once in the beginning; in my IDE I have a added a custom 
build step "cp ./src/pd.dll ./pd-0.x.x/bin" that just copies the 
(unstripped) Pd DLL into the bin folder (assuming I only want to 
test/debug the Pd core and not one of the externals in "extra").

Cheers,

Christof
