Initial build fails if /tmp and /home/USER are not the same partition #1

Closed Kijewski closed 2 years ago

E.g. because /tmp is a tmpfs (i.e. mounted in the RAM, not on a disk).

Error: failed to splat Microsoft.VC.14.29.16.10.CRT.Headers.base.vsix

Caused by:
0: failed to move /tmp/.tmpEiI3xs/unpack/Microsoft.VC.14.29.16.10.CRT.Headers.base.vsix/include/pplcancellation_token.h to /home/YOUR_NAME/.cache/cargo-xwinbuild/xwin/crt/include/pplcancellation_token.h 1: Invalid cross-device link (os error 18)

This problem can be circumvented by

  1. creating a folder /tmp/cargo-xwinbuild, then soft linking /home/YOUR_NAME/.cache/cargo-xwinbuild to it,
  2. building your program,
  3. removing the soft link and moving the directory.

Afterwards everything will work fine for later executions of cargo xwinbuild.

Thank you for this fine tool! I'm astonished how fast the compilation is! (And that it actually works :) )

Thanks for the report, I'm glad it worked for you in the end.

I plan to add some options to let you customize CRT/SDK cache directory in the next release, hopefully it will improve the current situation.

Please give v0.2.0 a try, you can now specify cache directory via XWIN_CACHE_DIR env var or --xwin-cache-dir CLI option.
