Long time ago we add possibility to build Clang into mingw-builds scripts. Now we want to provide Clang builds for mingw-w64 toolchains. There are two possibilities that we can do: *1. *Include clang builds into toolchain archive *2.* Provide separate builds of GCC+Clang I have a question to users what use our toolchains. I want you to vote for the best variant of doing that. I know that some users don't want to have bigger toolchains but I think that in modern time it is not a problem because all drives has big volume. Regards, Alexey. I would like to see a separate build for GCC + Clang, I would also like to know 1) if it is now possible to have 64 bit clang with SEH ? 2) If clang can work with a more recent libstdc++ (say 4.7.2 or 4.8 ? ) 3) most importantly, can we now debug clang compiled code with gdb ? (That was not possible with Ruben's build) I would also like to see 1) some clang tools along with the compiler. like clang-analyzer/ format/modernizer etc ( and include what you want, if possible) 2) debug release libraries for clang llvm, so that one can also use it like Clang C++ SDK to build new tools. Also in long term i like to see ( I hope it is sorter than i think! ) libc++ lldb working on windows, along with some other clang tools like Address Sanitizer, Memory Sanitizer etc Thanks abir -- CenturyLink Cloud: The Leader in Enterprise Cloud Services.

Also in long term i like to see ( I hope it is sorter than i think! ) libc++ lldb working on windows, along with some other clang tools like Address Sanitizer, Memory Sanitizer etc I would guess the Sanitizers should work, but I haven't tested. libc++ is on my todo list (still needs quite some work, but it passed most tests at one point, with a very hackish setup, which I am now trying to improve quite a bit), and lldb will probably not be for this year, if history is any indication.

Due to some ABI incompatibilities, Clang 3.4 will only work with older versions, like 4.6. Clang from svn works with recent versions. Check this bug http://llvm.org/bugs/show_bug.cgi?id=18034report. It says it support enough of the ABI to bootstrap and run all the tests. 3) most importantly, can we now debug clang compiled code with gdb ? (That was not possible with Ruben's build) I haven't checked, but I think something is going wrong on the Clang side wrt debug info. No idea what or how to check. Ideas welcome. I'm able to debug Clang programs on gdb. Though i've only tested with trivial programs. I would also like to see 1) some clang tools along with the compiler. like clang-analyzer/ format/modernizer etc ( and include what you want, if possible) 2) debug release libraries for clang llvm, so that one can also use it like Clang C++ SDK to build new tools.

Now we want to provide Clang builds for mingw-w64 toolchains. There are two possibilities that we can do: *1. *Include clang builds into toolchain archive Please don't. Clang is experimental as a Windows C compiler and useless as a Windows C++ compiler. It has its uses, but it is no match for gcc/g++ yet. If you include it into the stable toolchain archive, uninformed people will waste their time trying it to end being frustrated and disparaging MinGW-W64. Be patient ;-), dllexport for classes is on its way (patches are being finalized and merged). Then it'll be useful as a 32-bit C++ compiler. 64-bit is still missing EH stuff unfortunately. *2.* Provide separate builds of GCC+Clang I have a question to users what use our toolchains. I want you to vote for the best variant of doing that. I know that some users don't want to have bigger toolchains but I think that in modern time it is not a problem because all drives has big volume. There are still parts of the world with slow and/or limited Internet connections and people using old computers. Personally, I'm more concerned about potential clashes with the Clang binaries that I build. As Clang is experimental and fast-evolving on Windows, it makes sense to build it quite frequently from SVN and a stable distribution becomes obsolete quite fast (the standard response for bug reports against Clang releases on the Clang/LLVM channels is use the SVN sources.) I would also suggest an addon package as I previously built when I was an active toolchain builder. This is a extract and use kind of thing, and relied on the main GCC package. I do think a release build would be useful. Not that much changes on the Windows front, although I have a feeling 3.5 will be a nice one :-) Anyways, I'm currently working on getting native MinGW-w64 Clang Driver support written. Unfortunately, there are still bits and pieces (specifically libgcc, and crtbegin/crtend, and libstdc++/libsupc++ which depend on a working MinGW-w64 cross-compiler :-(). I'll try to get as much as possible ironed out, any help on this front (i.e. getting GCC-less runtime libraries working) is appreciated!

I am assuming that most of the users of MinGW64, especially the users of your prebuilt binaries, are just interested in a compiler that they can use. Bundling 2 compilers together would just make using the package more confusing. People (including myself) like your packages because they make using the toolchain much less confusing. -- ˙uʍop-ǝpısdn sı ɹoʇıuoɯ ɹnoʎ 'sıɥʇ pɐǝɹ uɐɔ noʎ ɟı -- CenturyLink Cloud: The Leader in Enterprise Cloud Services.
