I'm trying to build Skia for 32-bit Windows. I was able to make a build for 64-bit Windows eventually but upon following the instructions for 32-bit builds I'm met with a wall of errors. I've seen other threads with the same issues but they are outdated and contain little practical info.

I have downloaded the VS Build Tools and reinstalled my Windows SDK multiple times.
I was unable to get Clang working when building 64-bit so I am not attempting to use it currently. From what I can tell there is an issue with SetEnv.cmd missing as that is not included in the Build Tools anymore but I am unsure.

Error:
'C:/Program' is not recognized as an internal or external command,
operable program or batch file.
I do not know enough about CLIs and bash scripts etc to be able to solve this myself so I'm hoping someone has updated info on 32-bit builds.

What's happening there is the script is attempting to access
SetEnv.cmd
which is non-existent. The path itself is properly whitespaced & quoted etc.

Of course that's the cause of the immediate error. It would require
investigation to see if the x86 side of this should be updated to
match the arm64 side, except for replacing the last 'x64' with 'x86'.

above is not quoted or escaped, which is the cause of the error
message given. Whether or not SetEnv exists doesn't really matter at
this point. However, if it does not exist anyway, then obviously
quoting will not fix that.

Again, I have put quotes into that path string correctly and received the same error regardless.
I was able to find a dumb solution by messing with the scripts:
toolchain("msvc") {
lib_switch = ""
lib_dir_switch = "/LIBPATH:"
bin = "$win_vc/Tools/MSVC/$win_toolchain_version/bin/HostX64/$target_cpu"
env_setup = ""
if (target_cpu == "x86") {
# Toolchain asset includes a script that configures for x86 building.
# We don't support x86 builds with local MSVC installations.
# env_setup = "$shell $win_sdk/bin/SetEnv.cmd /x86 && " <----------------------------------- ** Comment out this line **
} else if (target_cpu == "arm64") {
# ARM64 compiler is incomplete - it relies on DLLs located in the host toolchain directory.
env_setup = "$shell set \"PATH=%PATH%;$win_vc\\Tools\\MSVC\\$win_toolchain_version\\bin\\HostX64\\x64\" && "
}
lib_switch = ""
lib_dir_switch = "/LIBPATH:"
bin = "$win_vc/Tools/MSVC/$win_toolchain_version/bin/HostX64/$target_cpu"
env_setup = ""
if (target_cpu == "x86") {
# Toolchain asset includes a script that configures for x86 building.
# We don't support x86 builds with local MSVC installations.
# env_setup = "$shell $win_sdk/bin/SetEnv.cmd /x86 && " <----------------------------------- ** Comment out this line **
} else if (target_cpu == "arm64") {
# ARM64 compiler is incomplete - it relies on DLLs located in the host toolchain directory.
env_setup = "$shell set \"PATH=%PATH%;$win_vc\\Tools\\MSVC\\$win_toolchain_version\\bin\\HostX64\\x64\" && "
}
As a non-google user of Skia I would strongly suggest updating the information on the Skia site for using Skia in a project. Far too many of the steps just do not work and the entire experience has been a months-long headache.
