Odd, it builds fine on my system. Did you sync down the code on Windows or
WSL, and to a Windows or WSL directory? My code actually lives in Windows
under /mnt/c/...
Yes, otherwise it wouldn't have worked at all since Windows can't reach
the WSL paths. The src was cloned in Cygwin originally.
I believe there is a difference (regarding case sensitivity) depending on if
you are on a Windows filesystem or a WSL filesystem.
I don't think this is really about case sensitivity, but it could be a
symptom.

Hello,
I took your patch for a spin, and configure passes, but I get the
same build error I got with my patch:
fatal error C1083: Cannot open compiler intermediate file:
'd:\erik\jdk-wsl\build\windows-x86_64-server-release\hotspot\variant-server\libjvm\objs\build_libjvm.pch':
No such file or directory
This is repeated for every C++ file in Hotspot. I see two issues
here. First of all, I need to figure out why the compiler will not
find the file, which is clearly there. Second, why isn't this failure
picked up by make? Somewhere the return value of cl.exe is disappearing.
Can you build without errors if you disable PCH?
Also, a wild guess: can it be related to file permissions? Can you
read the file properly from both WSL and Windows?
It is readable, but it could be something with case. The file is actually
called BUILD_LIBJVM.pch, but that is also how it's given to the compiler
command line. Here is the output from DEBUG_FIXPATH:

An interesting note is that make is rebuilding the pch file on every invocation
so it too has trouble finding the file.
