I do understand dependencies :) I just didn't think it was necessary to list that all out. However, this clearly isn't a dependancy issue! (Unless you are saying I have to use autoconf 2.5 or something instead of the current 2.68). I grabbed glib, devel stuff, pkgconfig, etc. Its all setup. Paths to mingw in msys setup. All the work to get things going are done.
Now, if what you're really saying is that no one works with the 32 bit version anymore, and so its basically unsupported, I'll grab the x64 msys....its just a hassle because internet access is slow here. I am an assembly optimizer, so I fully understand the benefits of x64. I also know very well QEMU is software only. I'm actually looking to emulate ppc to become a little more familier with the architecture before I have actual hardware to play with. I understand there is a wide range of PPC hardware, but the instruction set is still roughly similar.Given that its RISC I'm not sure exactly what I'm going to be able to do in assembly to speed things up unless when I get to my target platform I find the compiler is terrible at register management or something equally silly. (Its terrible on x86! So many performance gains can be had just by using ecx/rcx for something other than a loop counter when there isn't a loop going on! but I digress). Anyhow, if you do a fresh pull, grab dependencies, and get the build env all setup, you should see the same error starting with the autoconf issue. I'm still yet to figure out the undefined reference to _impure_pointer issue...most pages that talk about it are in the context of cygwin, and I havent touched cygwin since deleting the directory and re-extracting the archive. -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1276847 Title: Build fails on latest MinGW Status in QEMU: New Bug description: I've run across all sorts of problems. The first was simple, warnings treated as errors, and a warning of -fPIC ignored because its generating all code as position independant. Next came the %hhx's everywhere. MinGW is apparently following old MSVC non-C99 compliant systems, and hhx is not defined. Again, warnings as errors killed the build. zlib can never be found, for some reason I have to add a -I /include. %llx is also not recognized on mingw, but MinGW does have inttypes.h, so those could easily be converted to PRIx64's with a regex. asprintf is not included in MinGW, used in srcpos.c only so far, so I added an implementation in my build driectory which I found online. lstat is not part of mingw, and ntfs's links are different anyhow, so I #defined lstat to stat. fnmatch is included in libiberty, so I had to frab fnmatch.h from MinGW's sourceforge and then add the -liberty statement to the makefile. I get the feeling though, based on the number of warnings I'm seeing flash across as the compiler attempts to go through this that there are going to be more errors to fix. Catching the initial errors was quite tough because for some reason in pixman and dtc the errors couldn't cause compilation to stop, and running make again wouldn't attempt to rebuild the failures. I had to watch it like a hawk and ctrl-c it when I saw an error until I finally got a build! For reference, my build system looks like: User@Computer /c/projects/qemu-1.7.0 $ gcc -v Using built-in specs.
