Description

System Information
Operating system: Windows 10

Blender Version
Broken: 2.93.0 Alpha, branch: master, commit date: 2021-04-06 21:02, hash: e0a1a2f49dab
Worked: 2.91, 2.92

Recent 2.93 always gives cryptic errors when trying to compile any OSL script:

ERROR: error: C:\_WPLabs\Downloads\oslScriptFail.osl:1:10: warning: non-portable path to file '"c\\_WPLabssProgramsmblender29322.932scriptsraddonsacycles\shader\stdcycles.hd'; specified path differs in case from file name 
on disk
#include "c:\\_WPLabs\\Programs\\blender293\\2.93\\scripts\\addons\\cycles\\shader\\stdcycles.h"
         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
         "c\\_WPLabssProgramsmblender29322.932scriptsraddonsacycles\shader\stdcycles.hd
Error: OSL script compilation failed, see console for errors

Scripts are perfectly valid, even simple oneliner cant compile with recent alpha.

To reproduce: try to reload script in attached blend and look into console for this error

Can confirm, will check.

note I am getting a slightly different error:

ERROR: error: In file included from /08_Bugtracker_reports/T87279/oslScriptFail.osl:1:

Cant repro here in a local build, but can with the builds from buildbot.
I assume this has to do with the library upgrades in SVN r62577?

Actually, this has been reported before, see T86928: Error: OSL script compilation failed, will merge these reports.

Hopefully a631a9eb1f0b solves this for you @Ilja Razinkov (IPv6).

What I am wondering about is how c:\\_WPLabs\\Programs\\blender293\\2.93\\scripts\\addons\\cycles\\shader\\stdcycles.h gets changed to c\\_WPLabssProgramsmblender29322.932scriptsraddonsacycles\shader\stdcycles.hd
: gets dropped and 7 \ are replaced with s m 2 2 r a d

Sorry, but latest build STILL gives compilation problems. I assume that build already contain commit?

version: 2.93.0 Alpha, branch: master, commit date: 2021-04-10 16:36, hash: ed5507de8a25, type: Release

Moreover, Blender hangs when i tryed to compile script // Once. Most of times this gives error (with mistry chops), once it hanged completely

It is still not working (latest build from 14 apr)... really wish to switch for 2.93 because of Geometry Nodes, but this problem completely break workflow :(

Should i create another bug report instead of this one?
