*Official* mingw gcc 4.4.0

[imbaczek]

Release notes

most interesting for spring will be

Code: Select all

- Shared libgcc: If all modules are linked with -shared-libgcc,
  exceptions can be thrown across DLL boundaries.  Note that this is
  the default for all languages other than C.

- Zero cost exceptions: New exception model Dwarf only has performance
  penalty when being thrown.  The old model, SJLJ, is no longer
  available.

- Thread local storage support: The  __thread keyword is honoured.

edit: mingwlibs for this gcc release: http://cloud.github.com/downloads/sprin ... _dwarf2.7z

Did you tried if it fixes the exception leakage?

[imbaczek]

need to recompile the whole spring _and_ relevant parts of boost. will take a while but i'm doing it now.

current master doesn't crash at exit which would mean exceptions are fixed.

this makes mingw gcc 4.4.0 the recommended if not the required gcc version on windows.

bibim: please please please install it on buildserv?

Please don't forget to update mingwlibs.

uploading already.

btw your v19 can't be downloaded, it's some xml file instead of the archive...?

as you compile boost with this new exception types, does this mean we need two separate mingwlibs now? one for 4.4.0+ and one for - ?

[imbaczek]

yes, unfortunately.

but tbh we shouldn't need other mingwlibs because mingw currently supersedes any compiler used to date; you can think of even gcc 4.4.0-tdm as deprecated/unsupported as of now.

[hoijui]

you mean... you want ot force everyone to use the new mingw?
it would be ok in my eyes, as long as we hav ereally well documented steps for installing mingw on windows, and well documented minimal version requirements for linux (cross compiling) in obvious places (eg the Wiki).

[imbaczek]

yes, because it's the first mingw that will really work (it catches exceptions, at last!)

[zerver]

Maybe Dwarf exceptions work in conjunction with threading too :) that would be hueg improvement.

[imbaczek]

dwarf2 afaik is the system that virtually everybody else uses, ie. a shared memory area in a runtime dll (that's why you need -shared-libgcc). chances are it works fine. (i may be mixing up some stuff ^^)

I have installed official mingw gcc 4.4.0 and tdm gcc 4.4.0 on buildserv, but somehow they failed when linking with mingwlibs v19 :/

[Societal]

I deleted my 4.4.0TDM directory and replaced it with the following packages:

binutils-2.19.1-mingw32-bin.tar.gz (one older file than ggc-full)
gdb-6.8-mingw-3.tar.bz2 (lots of older files than gcc-full)
gcc-full-4.4.0-mingw32-bin-2.tar.lzma
mingw32-make-3.81-20080326-3.tar.gz
mingwrt-3.15.1-mingw32-dev.tar.gz
mingwrt-3.15.1-mingw32-dll.tar.gz
mingw-utils-0.3.tar.gz
w32api-3.13-mingw32-dev.tar.gz
diffutils-2.8.7-1-bin.zip

I have no problems compiling with mingwlibs_v19_dwarf2.7z here.

[bibim]

Thanks Societal, but buildserv is cross-compiling, it's a bit different

However it's fixed now. Concerning tdm gcc 4.4.0 I had some libglew conflicts between mingwlibs and mingw_cross_env, and concerning mingw gcc 4.4.0 I had forgotten to adjust the dwarf2 flag when compiling gcc...

mingw64 still fails though :/

Code: Select all

mingwlibs/include/boost/thread/win32/basic_timed_mutex.hpp:152: error: cast from 'void*' to 'long int' loses precision

[hoijui]

someone who already did it, please update the pages linked here:
http://springrts.com/wiki/Building_spring#Compiling
with the instructions for 4.4.0 for windows and cross-compiling.
if you did so, i will test it and add some comments here and there where i had problems, if any.
..please!!! :D

bump for the update on the compiling instructions for the gcc 4.4.0, because apparently for some reason I can't configure it by using cmake and I did the installation manually, because the automatic installation isn't updated with the latest MinGW release. It gives me this following error. When I try to configure it.

Code: Select all

Well apparently it can't seemed to find the crt2.o file and I did a search on it and it doesn't seem to find it. Were can I find and download the crt2.o file located in the list of MinGW downloads?

Extract these to your MinGW directory.
