Windows / Lua packages

[Nyyrazzilyss]

I'm trying to get the required lua packages to install on Windows 10. While I poke at it and try figuring out where i'm erroring out, i've included the messages i'm getting from attempted install of the various packages (following the win7 compile instructions). Among other things, it appears that it's attempting to use msvc lib files, rather then the mingw generated files. Anything obvious stand out? I do recall comments about LuaZip in the other thread, I haven't really looked at that yet (mostly been trying to get sqlite3 to link properly)

Results:

-- still erroring, i've seen mention about that previously i'll take a look

They are building, though loading them is another issue -

I'm re-reading an older post about Win7 compilation where various people were having issues with lua/versions.
http://forums.mudlet.org/viewtopic.php?f=7&t=3556

Judging from the below message when luarocks installs, i'm likely having issues with it recognizing 5.1.5

Could not find Lua. Will install its own copy.

(edit2)

Luarocks is looking for lua51.dll, which the lua 5.1.5 Makefile wasn't creating. I changed TO_LIB to create it

TO_LIB= liblua.a lua51.dll

The file was created now in /mingw32/lib, and a binary compare against the version shipped with Mudlet only had a 10 byte difference (filesize however was indentical).

Luarocks however would crash on install attempt, I needed to add c:\mingw32\lib into path. It now installed successfully, and I rebuilt everything (except LuaZip, which I really haven't looked at yet)

I've recompiled/rebuilt everything, but now when I attempt to connect to a profile mudlet crashes

[Nyyrazzilyss]

I wiped out everything, and reinstalled from ground up making sure I didn't have anything extra left behind/installed (Especially multiple versions of lua!). Getting there!

Now time to address the luazip thing

(edit 2)

Got zzip to compile following the below instructions - Installing LuaZip still not quite working.

Me too.




edit 1: Also, to the person that was having issues with their mudlet just crashing without telling you why, if your OS has an event viewer, see if you can find anything out from that? On Win10 I can open the start menu and search for event viewer, open that program, and looking in the following place, I was able to see that mudlet.exe was crashing due to something in lua51.dll, although i couldn't get any more information than that. I don't have the same crash pulled up, but this is close to what it looked like, except line P4: said lua51.dll or something.

[Nyyrazzilyss]

I did a search on the errors we're getting, and it appears to be from zlib (-lz) not being linked. Not sure how i'll force that, though (i'm not really familiar with luarocks)

Still not linking properly (on windows) but I found a somewhat more recent copy of the LuaZip source code at https://github.com/rjpcomputing/luazip

Searching the forum here, i'm not really finding much other then people having difficulties with building it (LuaZip), and old talk of replacing it with a different package that is easy to assemble in windows. There's more then a few threads where it looks like people reached LuaZip (in Windows) and gave up. In my 'trinity' of bugs I was concerned with, one of them had to do with the lack of error message when running into problems unzipping/installing packages. Would LuaZip also be where the lack of error messages was coming from? If so - LuaZip seems to be an abandoned package. Why not fork it into mudlet? Or perhaps revisit the idea of replacing it with QuaZip (on Windows, at least)

[Nyyrazzilyss]

Oh just as an aside - Not really directly related, however after retrieving all the individual source packages - A much easier way to untar all of them in the directory at once is

for a in `ls -1 *.tar.gz`; do tar -zxvf $a; done

[SlySven]

No, the lack of runtime error messages in handling zip files is less than perfect coding in the C++ (to a C libzip library).

One thing about those zip error messages might be the version of libzip - the current code is using some calls to that library that are now obsoleted (in the 1.x versions) whereas they were correct in the 0.10-0.12 that was current up to around 18 months ago - if people or their system install the latest version I wonder whether there will be issues in the future when/if they get to a 2.x and complete remove some obsolete calls...

[Nyyrazzilyss]

Woot! I got LuaZip to compile/load successfully in Mudlet! I'll probably have to redo for exact instructions, however -

I downloaded/extracted LuaZip from the above rjpcomputing link.

The commands to build the dll (from inside the luazip-master directory) were

gcc -O2 -c -o src/luazip.o -IC:/mingw32/include/ src/luazip.c -Ic:\mingw32\include
gcc -shared -o zip.dll src/luazip.o -Lc:\mingw32\lib -lzzip -lz c:\mingw32\lib\lua51.dll -lm

This created a zip.dll file that worked successfully when I copied it to my release directory It worked, though also looks like i'm including \mingw32\include twice

Almost there... Just need to figure out the LuaGlobal thing now.

(edit)

It looks like the LuaGlobal.lua I placed in the home directory (c:\release) isn't being loaded. The one located in mudlet-lua\lua however is.

(edit 2)

I was using the wrong mudlet-lua folder. I copied it over again, and everything is working properly.

I'm currently running a full compile of the recent posting of the new mapping structure, with an extremely large custom lua package. Everything appears to be working properly/no errors/etc, i'll leave it running overnight.
