Hi, can't require C module about dogfood HOT 6 CLOSED

Hello, I'm sorry to react this late.
Nice to hear you like it!
I will investigate your issue.

from dogfood.

I've tried to reproduce your issue but did not got the same result.
But instead of the 'lfs' I used my own filesystem module and that worked.

The following three points may help you.

Do you use the pre-build binary?
In that case, then issue could be that the pre-build dogfood binaries are build with MSVC which may not be compatible with your Lua Rocks configuration (I assume).

Are the C modules and the dogfood executable of the same platform (x86/x64)?

Are you sure that you placed all the dependencies/DLLs required by 'lfs', 'socked' 'iuplua', 'gbk' are placed too in the same folder as these C modules? You can use Depdency Walker to figure out what is missing.

Hi,
I use dogfood53_win_x86-32.zip and C module for lua 5.3.
I attach 'lfs.dll' and all the demo. I'm not sure compile compatible problem.

I use pre-compile binary for lfs.dll and lua5.3 from official, generally not suffer any compatible problem.
But the issue presents like a lua5.1 interpreter handles a 5.3 module - process blocks till some timeout, then program stop, without any error message.

Are the C modules and the dogfood executable of the same platform (x86/x64)?

Yes, they are. Otherwise, there will be prompt: error loading module 'lfs' from file 'lfs.dll', %1 not a valid Win32 application.

Are you sure that you placed all the dependencies.

Yes. Otherwise, it will prompt "module 'lfs' not found".

Demo:

--test.lua
print(_VERSION)
package.path=''
package.cpath='?.dll'
print(package.cpath)
--	require'lfs'
local _,lfs=assert(pcall(require,'lfs'))
print(lfs)
print'test OK'

Step:

1. dogfood.exe test.exe test in cmd.
2. test.exe, will get

D:>test.exe
Lua 5.3
?.dll

D:>

Files:
dogfood_test.zip

• lfs.dll
• test.exe
• test.lua

Thanks for your work, again~

The lfs C module required lua53.dll.
However when I added lua53.dll then a 'multiple Lua VMs detected' message was displayed in the command prompt.

The pre-build Lua binaries are statically build with Lua which effectively disables support for C modules.
So, dogfood needs to be dynamically linked to support C modules.

I really liked the single dogfood executable without dependencies.
Its possible to embed a DDL in an executable but that requires a change to dog.c and the Visual Studio project files. I will try this but I'm not sure how it turns out.

I've managed to embed Lua53.dll into the dogfood executable.

This zip contains a debug build of dogfood for Lua 5.3
It runs your test without errors.
Can you try this build with other libraries?

A new release of dogfood has been made.
Also the pre-build binaries are updated to include the fix for your issue.
