[Coin-discuss] cygwin build

Tue Aug 15 11:56:27 EDT 2006

Hi,

On Cygwin, currently the COIN makefiles always use the '-mno-cygwin' flag 
when it compiles code.  This is done because then the generated 
executables use the native Windows runtime libraries (not Cygwin1.dll) and 
therefore run also outside the Cygwin environment, i.e. in DOS, which is 
what you probably want when you compile an executable and want to use it 
"natively" in Windows (e.g., the AMPL solver executables).

But this requires that all code, also the code that links with the 
library, is compiled and linked with that flag.  If you use the Makefiles 
in the examples subdirectories, you will see that the flag is there.

It seems that a number of people are not happy with this, since it also 
changes what header files are used etc.  I'm planning to change the 
behavior so that by default the -mno-cygwin flag is not used, but that a 
user can choose --enable-dos-compile (or so) on Cygwin, which would then 
generate a native Windows executable.  I already submitted a BuildTools 
ticket (to myself) and will try to get to it soon.
