Cygwin problem, libc6

qrange · 01-14-2011, 03:05 AM

I'm not sure if this is the right sub-forum..

There is this program that compiles and runs nice on Linux Debian, but I need it to compile in Windows XP, so that it can run there as *.exe
I installed Cygwin but it seems some libraries are missing. The source file says I need, among other things, this in Debian: libc6-dev

How to install that in Cygwin? (make complains about stubs.h)

thanks.

if it is a linux.exe then it was built in MniGW and NOT CygWin

you need to use the MinGW .la or use dilltool to make the MS .dll
Gnome.org has large section for mingw

I don't understand, its not linux.exe
The program is opensource, I downloaded it as tar.gz and it compiles nicely in Debian just using command 'make'.
But, now I want windows binaries. Preferably so that it works in Cygwin 'environment' on Windows, because it uses some system commands (namely 'mkfifo').
and compiling needs to be done in Linux, because windows Cygwin lacks libc6 and other stuff.

you stated the program WAS A EXE FILE

so that it can run there as *.exe I installed Cygwin

therefor it was NOT A CYGWIN BUILD BUT A MINGW ONE !!!

cygwin dose NOT build librarys for windows *.exe files mingw dose ( .la and windows .dll's )

cugwin dose NOT build windows binary’s. MinGW dose

cugwin RUNS linux binary’s ON WINDOWS

cygwin DOSE NOT run windows binary’s MinGW dose

for cygwin just build the lib ON windows in the
c:\\CygWinRoot/usr/src/???
at you would on linux and install it ( --prefix=/usr)

You can compile things in Cygwin, but you need to install gcc first. I think the Cygwin setup.exe acts as a package manager. You'll need make, gcc, and libc-devel (Cygwin is from Redhat, so it uses the -devel suffix not -dev).

mingw is now using the same style as Cygwin
the setup/install.exe IS the package manager
as i recall the Ibidio.com is one of the fastest mirrors

No, it doesn't. All commands in C:\cygwin\bin are .EXE files. If I copy Linux binaries there it says: "cannot execute binary file".

Now I want to run crosscompiler in Linux to get Windows binary, because Linux has all the needed libraries.

In the same way you can't use Linux executables in Cygwin, you can't use the libraries either. Cygwin is (mostly) source compatible with Linux, not binary compatible. I think you can cross compile from Linux, but you will need to cross compile the libraries as well.

I see, well there must be an option to include the compiled libraries when making .exe? I mean the crosscompiler in Linux could search for installed source files of needed libraries and 'attach' them to the source of program, so that the result is just one file, right?

Yes you can do static linking which includes the libraries in the final exe. I still think it's easier to setup the compiler on Cygwin than setting up a cross compiler on Linux.
