>From 4e8dec03681b223fa7eec05c8a5a49ef11165b18 Mon Sep 17 00:00:00 2001 From: Vladislav Dzhidzhoev <vdzhidzh...@accesssoftek.com> Date: Mon, 15 Jul 2024 22:52:40 +0200 Subject: [PATCH] [LLDB][test] Update Makefile.rules to support Windows host+Linux target These changes are aimed to support cross compilation build on Windows host for Linux target for API tests execution. They're not final: changes will follow for refactoring and adjustments to make all tests passing. Chocolatey make is recommended to use, since it is maintained better than GnuWin32 recommended here https://lldb.llvm.org/resources/build.html#codesigning (it was updated last time in 2010) and helps to avoid problems with building tests (for example, GnuWin32 doesn't support long paths and there are some other failures with building for Linux with it).
