Re: [Mingw-w64-public] Problem with MSYS on 64-bit
Mercurial is a revision control system (like git, svn, etc). In other words it was fixed after the release and is in their public repository. You can safely ignore that particular test's error, the bug is in the test-suite program itself. If you want to see it be clean, you could apply the patch that I posted and rerun the test.

Could I ask for an explenation? Also, does your reply mean that I can ignore the error I got from make check? I used MSYS to build MPFR using ./configure --disable-shared --host=x86_64-w64-mingw32 --with-gmp-build=/home/chris/gmp-5.0.1 and make check ran with no errors.

[Mingw-w64-public] Dwarf-2 debugging support?
Hi there, Our project (MAME) recently converted a bunch of C code to C++, and as a result our symbol size has bloated tremendously (EXE is now 280MB(!) with symbols, versus 40MB without), killing our link times. Our cohorts on the Linux side have not noticed any significant difference. After some investigation, it looks like the difference is due to stabs versus DWARF debugging information. We are using the sezero builds. I tried forcing mingw-w32 to output DWARF-2 (via -gdwarf-2; also tried -ggdb) but the binary size ends up almost identical. I strongly suspect that the compiler was not built with support for generating DWARF symbols and is just ignoring my pleas. I know the DWARF EH model is not supported, but from what I understand, the support for DWARF debugging information is independent of the EH model. So basically: 1. Can you confirm/deny the existence of DWARF debugging support in current sezero builds? 2. Are there other builds of the 4.4.x tree we can use that have this enabled? 3. Or alternately, Ozkan, can we convince you to turn this on for your builds? :) Thanks, Aaron -- ThinkGeek and WIRED's GeekDad team up for the Ultimate GeekDad Father's Day Giveaway.

DW- 2 debug is already in use with -gdwarf-2, but DW2 EH on win64 don't work at all. There have been work on SEH but its not in GCC yet. Actually, no, I'm not confusing them, as I stated above: I know the DWARF EH model is not supported, but from what I understand, the support for DWARF debugging information is independent of the EH model. Regardless, after further investigation, it appears that the dwarf-2 debugging is the default after all, but interestingly for our case -gstabs produces much smaller binaries (132MB versus 280MB). Which is contradictory to information I've read in other areas where dwarf is supposed to be much more efficient. I still believe there is a significant size discrepancy between mingw and linux here. I will gather more information to understand what is going on. Aaron -- ThinkGeek and WIRED's GeekDad team up for the Ultimate GeekDad Father's Day Giveaway.

But in general you have here different possiblities to solve this. First of course by the debugging-level switch -gn. Additionally you can use object-copy tool to split debugging information into an separate file. The gstabs information isn't possible for x64, so I would recomment that you stick to the dwarf-2 information. In 4.4.x and 4.5.x series there are some tweak about debugging information and inlined code. To avoid this don't use debugging information (or strip them out into separate debugging file) for optimization levels = 1. Regards, Kai -- | (\_/) This is Bunny.

[Mingw-w64-public] FLTK 1.1.10 for w64
Hello Zhau, the FLTK 1.1.x devel library on [1] is not usable. There are missing some basic libraries (libfltk.a, libfltk_images.a). I think the build was incomplete, because the GCC stops on such errors: FL/Fl_Menu_Item.H:91: error: cast from 'void*' to 'long int' loses precision fl_open_uri.cxx:117: error: cast from 'HINSTANCE__*' to 'int' loses precision I know, that is not a MinGW problem. I would only note this here, and ask for an idea to build FLTK 1.1.x with MinGW-w64.
