How to distribute programs compiled on cygwin?

How to distribute programs compiled on cygwin?

[Srinivas Kommu]

I have a C program that uses the Win32 API and some curses functions. I was 
amazed at the speed at which I could develop this program with cygwin and 
gcc. cygwin is a wonderful thing, indeed. Now my problem is, how do I send 
this .exe to someone that doesn't use cygwin? Is there a way to get rid of 
the cygwin-specific dlls out of the executable? I tried -mno-cygwin but that 
seems to be something else, totally.

thanks a lot!
kommu

bash $ cygcheck a.exe
Found: .\a.exe
.\a.exe
  C:\cygwin\bin\cygncurses5.dll
    C:\cygwin\bin\cygwin1.dll
      C:\WINNT\System32\KERNEL32.dll
        C:\WINNT\System32\NTDLL.DLL

There is no way to remove the cygwin DLL from programs that use cygwin.  Sorry.

I couldn't find this info in the FAQ, but it probably should be there.

Indeed.  I'll add something.

Cheers,

Chris,

I added the following entry to the "Programming Questions" section of
the FAQ:

	"Can I build a Cygwin program that does not require
	cygwin1.dll at runtime?"

	No.  If your program uses the Cygwin API, then your executable
	cannot run without cygwin1.dll.  In particular, it is not
	possible to statically link with a Cygwin library to obtain an
	independent, self-contained executable.
	
	If this is an issue because you intend to distribute your
	Cygwin application, then you had better read and understand
	< http://cygwin.com/licensing.html >, which explains the
	licensing options.  Unless you purchase a special commercial
	license from Red Hat, then your Cygwin application must
	conform to the GPL.

I call your attention to the last paragraph.  I'm pretty sure it's
correct, but I don't speak for Red Hat, so someone should check that I
haven't lied.

Thanks,
David

It's perfect, David.

Thanks much for adding this section and for all of your work on the FAQ.
It is very much appreciated.

I've a little bone to pick: It's not consistent with the licensing.html
page which permits any opensource license, not just the GPL. This will
likely create confusion.

I second this.

Sorry!  Here's what is in the FAQ now:

    ... Unless you purchase a special commercial license from Red Hat,
    then your software must comply with the Open Source Definition or
    the GPL.

Better?

Cheers,
David

Why both ? (GPL is an OSD/DFSG license)

I'd make it ".. with the Open Source Definition, like the GPL."
                                                 ^^^^
Otherwise, ye might think GPL doesn't conform to the Open Source 
Definition..

Greetz!

Ah.  Well, I didn't actually *read* the OSD. :-)

Thanks for setting me straight, sorry for the ignorance.  And the
traffic.
