Re: [lttng-dev] Building the Babeltrace-Libary for Windows?

["Seidl, Aron via lttng-dev" <lttng-dev@lists.lttng.org>]

Hi Michael,

Thank you a lot for your answer! I think I can work with that.

I set up the msys64 environment with all the packages that I need to build, except for glibc. I ran the script and as always does the build process fail because I can't install glibc in this environment.
Even building glibc from source fails, because the system is not compatible.

Do you guys link babeltrace to a different C library when building on windows, or is there a way for a possible workaround?
I'd be super grateful for a little more help!

I wish you a nice day

Sincerely,
Aron

Hi,

It should be technically possible to cross-compile babeltrace2 with Mingw on Linux but it was never tested, so a lot a small fixes to the build system might be required.

What is tested however is building with Mingw in an MSYS2 [1] environment on a Windows host. You can have a look at the CI job [2] for the details, the configuration including the build script is publicly readable in "View Configuration".

Cheers,

Michael
