require'lfs' in Local console crash IDE.

[pkulchenko]

It doesn't for me; any further details? version, platform?

[robertlzj]

Win10, newest IDE and lfs.dll in folder clib53. Crash only happens in Local console, Remote console, editor is fine. (I think it's related with #1080 ) ~I'll try on another computer later.~

[pkulchenko]

Yes, it has to be related if you run it from clibs53, as the version to be loaded from the console has to be linked with lua51. I'm certain that it's related to the wrong version to be loaded, but can you run print(package.cpath) from the console to confirm?

[robertlzj]

print(package.cpath) from local console is different from neither run nor debug.

--local console
bin/clibs/?.dll;
C:\Users\RobertLin\AppData\Roaming\LuaRocks\lib\lua\5.3\?.dll;
c:\programfiles\zerobranestudio\\lib\lua\5.3\?.dll;
C:\Users\RobertLin\luaplus\Tools\JamPlus\bin\win32\lua\modules\?.dll;

lfs would been first found at c:\programfiles\zerobranestudio\\lib\lua\5.3\?.dll;, if \\ won't trouble. Or, been found at C:\ProgramFiles\ZeroBraneStudio\bin\clibs\ expanded for bin/clibs/?.dll;. But in both position, I put the right lfs.dll already.

Also test. Script print(require'lfs') in editor using Lua 5.1 won't work, print nothing with no waring in Output, just complete script. Same script in console make crash.

And doesn't lfs.dll compatible with all version of Lua. (I use LuaRocks to get it) So, why crashes still happen?

[pkulchenko]

Script print(require'lfs') in editor using Lua 5.1 won't work, print nothing with no waring in Output, just complete script. Same script in console make crash.

It's because when you Run or Debug your application, it's executed in a separate process, which crashes, but leaves your IDE process intact. When you try to load a wrong library into the same process as the IDE, it crashes and takes down everything with it, including the IDE.

Your path information confirms that you are loading a library from lua53 into the process that expect lua51 library, which will lead to a crash.

The question is, how did you get lua53 path into the one used by the Local console, as it should reference only paths for lua51 modules by default. Did you set it up in LUA_CPATH before loading the IDE or in user.lua?

[robertlzj]

My fault. I did modify LUA_CPATH in environment variables. Now I restore them (almost empty now).

[pkulchenko]

Right, you can use LUA53_CPATH, but shouldn't put lua53 libraries in LUA_CPATH.
