gml and thread-local storage

[ILMTitan]

I'm on windows compiling using mingw and scons.

I'm getting the error:

Code: Select all

My gcc is version 3.4.5. I looked through the SConstruct and rts.py and still have no clue how this problem started.

You need GCC 4.3.0 or higher to compile now because the multithreading library uses thread local storage. I'd recommend 4.3.1 since 4.3.0 seems bugged.

Edit: We need to change the mingw download instructions on this website so it points to a version that works :)

[imbaczek]

4.3.1 is also bugged, but, what's worse, hasn't yet been released even in alpha version.

[hoijui]

but imbaczek, you told me that you were able to compile with 4.3.0.

i also came around the lack of instructions to compile with MinGW 4. I wanted to do it and then actualize the wiki, but i also get errors still, though i seem to be close.

If anyone succeeded, pls actualize the Wiki!

Compiled fine for me, I think I'm using 4.2.1

[hoijui]

hmm.. well if you can, could you please explain how you setup everything? i guess it is already a while back, hm? :/

[KDR_11k]

I don't even remember how I got this mess to work but I spliced some testing build of GCC 4.2.1 into MinGW 3.4.5 (if I remember the version numbers right).

[rattle]

MingW 5.4.1, GCC 4.3.0
I'm able to compile again... or not.

After some googling it looks like that this is an issue with my gcc libs (*crt and some others). Though I have no clue right now . Any ideas?

edit: using gcc 4.2.1 seems to work

[ILMTitan]

Using those packages I too get those errors.

build\unitsync\tools\unitsync\test\test.o:test.cpp:(.text+0x510): undefined reference to `_InitArchiveScanner@0'

...great, unitsync fails too.

[imbaczek]

mingw g++ 4.2 and 4.3 are incompatible; that said, it links for me. I've got runtime crashes tho:

edit: missed unitsync, fails here too.
edit2: is it me, or has InitArchiveScanner disappeared completely?

[rattle]

Is that why spring ignores everything in the mods folder?

InitArchiveScanner has been deprecated (and a no-op) since like 0.74 or so. Don't remember whether it was actually removed later on or not, could very well be.

[zerver]

You should be able to use older versions of GCC again, since I have removed the TLS requirement if multithreading is disabled (which it is by default). Define _GML_ to enable multithreading.

* removed InitArchiveScanner() from unitsync
