Hi All,

Outcome build failed on MSVC, this issue can be reproduced on latest version https://github.com/ned14/outcome/commit/a853fc09bb9590204a33c62bd3fd32f9b212c69f on VS2019 16.7.6, can you help look?

repro steps:

  1. git clone --recursive https://github.com/ned14/outcome.git Outcome
  2. mkdir outcome\build_amd64 && cd outcome\build_amd64
  3. cmake -G "Visual Studio 16 2019" -A x64 -DCMAKE_SYSTEM_VERSION=10.0.18362.0 .. > cmake.log
  4. set CL=/D_HAS_DEPRECATED_IS_LITERAL_TYPE=1 /D_SILENCE_CXX17_IS_LITERAL_TYPE_DEPRECATION_WARNING /Zc:externC-
  5. msbuild /m /p:Platform=x64 /p:Configuration=Release ALL_BUILD.vcxproj /t:Rebuild > build.log

Build.log: build.log

This should have been fixed since. Can you confirm?

Thanks for the quick fix, verified that the following error can still be reproduced.

Confirmed. Relocating to the pcpp issue tracker, as the cause is there.

This should now be fixed completely. Thanks for the BR!
