Re: [Mingw-w64-public] changing a DLLs load-time dynamic link dependency
2013/11/15 Jon jon.for...@gmail.com: After skimming LRN's ntldd https://github.com/LRN/ntldd tool, reading tinype again http://www.phreedom.org/research/tinype/ and updating my upx http://upx.sourceforge.net/ I'm curious if binary tweaks to mingw built DLLs (e.g. - libffi, libxml2, etc) could easily solve one of the mingw/VC++ integration issues. Specifically, the using-the-same-msvcrt-version issue. Mingw GCC's default to linking against msvcrt.dll and the VC++ compilers link to other versions depending up toolchain version. The only fix I'm aware of is creative use of GCC spec files when building from source. One day I'll find time to swing back to work on my symlink-to-multiple-spec-files hack, but there's also the missing .a file concern. Could an easier solution be to simply build your DLL library (e.g. - libffi) with GCC that load-time dynamic links to msvcrt.dll, then munge the PE format to replace the reference to msvcrt.dll (a string?) to say msvcr120.dll (another string?) and then fixup all effected references/addresses in the DLL library? Essentially build a tool that creates binary copies of the original msvcrt.dll load-time linked DLL that switches the load-time link info to reference another msvcr*.dll version. Nothing else. Similar to working in the frequency domain rather than the time domain. Completely bypass source and spec file issues and just generate slightly tweaked clones of your original DLL. I've not spent enough time with the PE format or the MSFT system DLL Export Address tables, dynamic linker, ordinals, et al to know if this idea is DOA, but it's highly likely some of you know. I'm making a lot of assumptions, but what are the showstoppers to this idea? Anyone tried this, working on this, or know of a tool (binutils?) that already does this? RTFM links to get smarter? Thanks, Jon To introduce delayed-loading isn't working 100%. The none-function-imports especially making troubles here. Well, for proper decorated dllimport-ed symbols it works. Nevertheless are all feature of auto-import not working (pseudo-relocation etc). IMHO it would be easier to write a tool, which modifies the PE-header of a DLL/EXE.

[Mingw-w64-public] pthread_attr_setschedpolicy not implemented
Hello, versions posix-sjlj for 32 bits (I need C++11 threading) have pthread_attr_setschedpolicy not implemented I think that there are some versions of pthread that implement that feature.

Nevertheless, yes we lack this function. In general its implementation is pretty much trivial, as on Win32 target just SCHED_OTHER can be supported.

2013/11/15 Victor Bombi son...@telefonica.net Hello, Why cant we have C++11 threading with non-posix versions? Because libstdc++ implements thread, mutex and future on top of GCC's internal thread API, for which only the posix threads backend is implemented fully.

Regards, Kai Ah, so if I'm trying to change from this scenario exe (VC++) -- DLL (mingw-w64) -- msvcrt.dll to this scenario via binary hacks to the DLL exe (VC++) -- DLL (mingw-w64) -- msvcr110.dll are you saying I need to learn how to modify the PE header of *only* the mingw-w64 DLL, or are you saying *both* the DLL and exe PE headers need to be modified? Also, are you saying that the VC++ exe should *not* be delay load linked (i.e. - no /DELAYLOAD linker option) because this doesn't work reliably? I'm also assuming if I'm able to build this Frankenstein mingw-w64 DLL linked with msvcr110.dll not msvcrt.dll, I could still use pexports or gendef to create the .def required by VC++'s lib tool to create the import lib needed to link to the new mingw-w64 DLL that is linked to msvcr110.dll. Correct? Another wacky idea...is it possible to create a custom linker script https://sourceware.org/binutils/docs/ld/Scripts.html#Scripts that could persuade ld and its binutils friends to do this rewriting as part of its job of creating the mingw-w64 DLL?
