I'm using Yocto krogoth and meta-mingw to build the meta-toolchain for windows
system. The build is quite smooth.
I extract the built toolchain
poky-glibc-x86_64-meta-toolchain-core2-64-toolchain-2.1.tar.xz on windows to
c:/yocto2.1
However when I try to run a simple build from windows cmd console after I set
up the environment-setup-core2-64-poky-linux.bat, I got the following error.
By further check, it seems the error is related to the symbolic link in folder
sysroots/x86_64-pokysdk-mingw32/usr/bin/x86_64-poky-linux/../../libexec/x86_64-poky-linux/gcc/x86_64-poky-linux/5.3.0/
where the as, ar etc binutiles are the symbolic link to the file in ->
../../../../../bin/x86_64-poky-linux/
However on windows, such "../../" symbolic link can't work. Simply execute the
symbolic 'as.exe' will get error "Access is denied."
Anyone has the idea on how to solve this issue?
