Generating Linux Compatible binaries

Generating Linux Compatible binaries

[Goswami-EXT, Himanshu]

Hi,

I want to generate the Linux compatible binaries on Windows System.
Cygwin is a cross compiler which offers POSIX environment.
But I could not find any Unix libraries to generate the Linux compatible binaries.
Could you please advice any steps that I can follow?

Thanks in Advance.

Cygwin doesn't work that way.  It uses a custom built library that translates
POSIX system calls to similar Windows systems calls.  There are a few places,
such as file permissions, where differences will peek through.  Anyway, since
it does not run Linux compatiable libraries, it is not designed to build them.

The only solution I can recommend is to use a virtual machine, such as the Windows
Subsystem for Linux (WSL), Oracle Virtual Box, or VMWare.

Eliot Moss recommends a VM and that's a good option.

Another option is to use Cygwin to host a cross compiler. I  have used
Cygwin to build and install cross compilers that ran on Cygwin and
built code for my Raspberry Pi 2. There are many tutorials on building
and creating cross compilers and I won't try to equal them. But this
is a versatile method. If the target Linux was one that runs on a
different processor and a virtual machine would be inefficient or lack
the resources to carry out the build, then running a cross compiler on
your Windows machine, under Cygwin or otherwise, might be an option to
consider.

If you are on a recent Windows version your easiest option is probably
to use WSL and use native compilation on Linux.  second easiest is
likely to set up a VM to run Linux in (that might actually be easier
than WSL if you already have some virtualisation environment set up for
something else, but you said you were on Windows).

No, Cygwin is a user-space layer on top of Windows that provides a POSIX
environment for applications that target Cygwin (i.e. Cygwin
applications are neither Windows nor Linux applications).

Just like you'd do on any other non-Linux system: set up a
cross-compilation toolchain and start compiling all dependencies until
you can finally compile whatever Linux application you wanted orginally.

Following up my previous post and the two others I have seen ...

Cross-compilation is a definite possibility.  However, you can't test
the result directly under Windows or Cygwin.  If you want to test, then
AFAIK a VM (or maybe qemu?) is your only option.
