Bug ID: 46053
           Summary: Support cross-toolchains that need target sysroot
                    explicitly passed via '--sysroot' command-line option
                    (Yocto/Poky SDK)
           Product: Wine
           Version: 3.19
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: tools
          Assignee: wine-bugs@winehq.org
          Reporter: focht@gmx.net
      Distribution: ---
Hello folks,
I'm currently reviving/polishing up my local aarch64 and armv7-hf cross-compile
environments (lost interest some years ago when WinRT died). I seem to fail
building Wine with GCC/Clang cross-compilers that weren't built using the
'--with-sysroot' option. This is prettly much standard for all Yocto project
SDKs (cross-toolchain + full development sysroot, matching the target rootfs).
The Yocto project (https://www.yoctoproject.org/) allows to easily create
embedded Linux distros with full cross-development support (SDK). I often use
it at my work when porting/adapting various ARM SoC vendor Linux BSPs. No need
to go extra mile and manually cross compile any of Wine's dependencies - they
are already built into the target development sysroot. Everything is properly
set up, cross pkg-config, etc.
Linaro aarch64 Linux toolchains are not an option, they only contain a minimal
target sysroot. I want to build Wine with the same featureset as on my 64-Intel
host but for various non-Intel targets (armv7, aarch64, ...).
https://www.yoctoproject.org/docs/2.5/sdk-manual/sdk-manual.html
I succeeded on all things - except for the final linking step. I haven't found
a way to pass the target sysroot via '--sysroot' command-line option through
'winegcc' wrapper to the cross-compiler.
I've tried 'configure' with
* --with-sysroot="$SDKTARGETSYSROOT" (not supported)
* --extra-cflags and/or EXTRACFLAGS (EXTRACFLAGS works, except for winegcc)
* CFLAGS (works, except for winegcc)
