  • Do you have cmake installed? – sweenish Apr 01 '23 at 14:13

    This is likely a bug that the vcpkg developers need to fix. However with that said you need to look at the `G:\VCPKG\vcpkg\buildtrees\libtorch\build-torch_cpu-x64-windows-dbg-out.log` file as it contains more information about the problem. – drescherjm Apr 01 '23 at 15:25
  • yes, the vcpkg installed cmake. I try to install opencv4 with vcpkg with no problem. – Seyed Amirreza Kabodian Apr 02 '23 at 16:56
  • @drescherjm it says `LINK: fatal error LNK1102: out of memory ninja: build stopped: subcommand failed.` but I have enough free memory. – Seyed Amirreza Kabodian Apr 02 '23 at 16:59
  • You can limit the parallel jobs or increase the size of your page file. I think that means because there were many parallel builds going at the same time your system exhausted the available virtual memory during building and stopped with an error. – drescherjm Apr 03 '23 at 00:42
  • This is probably what you want: [https://github.com/microsoft/vcpkg/issues/22689#issuecomment-1019290439](https://github.com/microsoft/vcpkg/issues/22689#issuecomment-1019290439) – drescherjm Apr 03 '23 at 00:45
  • [https://learn.microsoft.com/en-us/vcpkg/users/config-environment#vcpkg_max_concurrency](https://learn.microsoft.com/en-us/vcpkg/users/config-environment#vcpkg_max_concurrency) try setting this to 1. – drescherjm Apr 03 '23 at 00:47
