Binary caching cannot cross host

[huangqinjin]

The triplet arm64-android-dynamic for testing.

set(VCPKG_CMAKE_SYSTEM_NAME Android)
set(VCPKG_CMAKE_SYSTEM_VERSION 24)
set(VCPKG_TARGET_ARCHITECTURE arm64)
set(VCPKG_CRT_LINKAGE dynamic)
set(VCPKG_LIBRARY_LINKAGE dynamic)
set(VCPKG_BUILD_TYPE release)
set(VCPKG_DISABLE_COMPILER_TRACKING ON)
set(VCPKG_C_FLAGS -s)
set(VCPKG_CXX_FLAGS -s)

It produces exactly same binary libsqlite3.so (same sha1) on Windows and Linux. But the two vcpkg_abi_info.txt are not same.

The first issue is that vcpkg_abi_info.txt on Windows contains powershell version.

The second issue is that vcpkg-cmake is a host dependency and it's vcpkg_abi_info.txt contains the host triplet information. This means that all package ABIs indirectly contain host infomation even we are cross-compiling.

I've employed a slightly hacky way to get around this: pass --only-binarycaching --host-triplet <triplet of original build that you want to re-use>

Of course, this only works if you know for sure all your packages are built and cached

Probably only works if you disable compiler tracking as well.

[huangqinjin]

@russelltg It does not work if the <triplet of original build that you want to re-use> is x64-windows.

On Linux, --host-triplet x64-windows outputs

error: in triplet x64-windows: Use of Visual Studio's Developer Prompt is unsupported on non-Windows hosts.
Define 'VCPKG_CMAKE_SYSTEM_NAME' or 'VCPKG_CHAINLOAD_TOOLCHAIN_FILE' in the triplet file.

And no way to bypass the different hash calculation between Linux and Windows.

The first issue is that vcpkg_abi_info.txt on Windows contains powershell version.
