Hi all, I am trying to enable a customer for using YP SDKs on Windows. It apparently is supposed to work, but I am unable to get past fatal errors.
I have looked for documentation at the YP site and the meta-mingw repo, but to no avail. 1) My project is a simple default "qemux86-64" with YP-2.5 HEAD, with the latest "meta-mingw" layer added and <SDKMACHINE ?= "i686-mingw32">. The SDK builds fine and I get the "*.xz" generated file. 2) However, when I use 7ZIP to extract it on my Windows host (which is recommended for XY files), I get several fatal issues. (a) I get more than a hundred errors "Can not create symbolic link: Access is denied". While I do not care about the ones for the bin tools in the sysroot, I do care that most of the cross toolchain EXE files are thusly broken, plus many of the libraries and header files in the sysroot. Am I missing a step? If I in fact extract this file on my Linux host, I can directly see that it is full of symlinks! Why are there symlinks in a Windows-specific tarball? (b) If I attempt to build a simple C file from the shell in the SDK environment, I either get a silent failure (for the 32-bit toolchain) or a blatant error as per: x86_64-poky-linux-gcc: error: CreateProcess: No such file or directory I am assuming this error arises from the broken symlinks, specifically all those broken files in: SDKDIR\sysroots\i686-pokysdk-mingw32\usr\bin\x86_64-poky-linux-gnux32 (all zero length): 03/04/2018 08:29 PM 0 x86_64-poky-linux-gnux32-addr2line.exe 03/04/2018 08:29 PM 0 x86_64-poky-linux-gnux32-ar.exe 03/04/2018 08:29 PM 0 x86_64-poky-linux-gnux32-as.exe 03/04/2018 08:29 PM 0 x86_64-poky-linux-gnux32-c++.exe 03/04/2018 08:29 PM 0 x86_64-poky-linux-gnux32-c++filt.exe 03/04/2018 08:29 PM 0 x86_64-poky-linux-gnux32-cpp.exe 03/04/2018 08:29 PM 0 x86_64-poky-linux-gnux32-elfedit.exe 03/04/2018 08:29 PM 0 x86_64-poky-linux-gnux32-g++.exe 03/04/2018 08:29 PM 0 x86_64-poky-linux-gnux32-gcc-ar.exe ...

Please help, David Reyna From: yocto-boun...@yoctoproject.org [mailto:yocto-boun...@yoctoproject.org] On Behalf Of Wang, Yang Y Sent: Thursday, August 17, 2017 11:41 PM To: Yocto Subject: [yocto] toolchain from meta-mingw gets error x86_64-poky-linux-gcc: error: CreateProcess: No such file or directory 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? c:\Yocto2.1>%CC% c:/temp/temp/temp/test.c x86_64-poky-linux-gcc: error: CreateProcess: No such file or directory c:\Yocto2.1>%CC% c:/temp/temp/temp/test.c --verbose Using built-in specs.
