Jim,

The build worked! It's the first successful MinGW64 build that I have had. This build was performed from within Cygwin using the mingw64 toolset. I am attempting a build with the MinGW build you pointed me to. Thank again!

However, when I attempt to compile the archive into my library I get the below error.

Isdmain.o:Isdmain.cpp:(.text+0x16c3): undefined reference to `boost::thread::start_thread()'

I have examined the library symbols and, indeed, I cannot find the appropriate externs. I jumped from 1.35.0 to 1.45.0. I was just wondering if you have any idea why this would start happening? Am I missing something? Any help would be greatly appreciated.

P.S. I will let you know if this changes with the new MinGW64 build.

I did run the regression test last night, FYI...

Last column. All tests pass but one.

HTH.

I have a trunk regression-test platform that runs Mingw64 on Win7-64. It's experimental and isn't in the regression matrix right now, but works as well as any MinGW platform (or pretty close). I use GCC 4.6 from here <http://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win64/Personal%20Builds/rubenvb/><http://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win64/Personal%20Builds/rubenvb/>. CygWin's not installed on this machine.

I've attached my complete set of patches. A little cryptic (and patches a pretty recent trunk revision), but should give you a set of changes that ought to get you close.

You should be able to use the pre-built bjam (32-bit). <http://www.boost.org/doc/libs/1_45_0/more/getting_started/windows.html#get-bjam><http://www.boost.org/doc/libs/1_45_0/more/getting_started/windows.html#get-bjam> boostrap.bat needs a little hacking for gcc.

Good luck!

Good Afternoon,

We have been using boost-threads for our native APIs and, thus far, Boost has been a godsend! We had a recent request to build a 64-bit version of this API. To accomplish this we have attempted to build using MinGW64. Unfortunately, I have had zero luck getting boost-threads to build. I can build the 32-bit address model without a problem but 64-bit continues to elude me.

I first tried Boost 1.35.0 and have now moved on to 1.45.0. I believe that the environment is set up correctly (see below). This build is being performed on a Windows 7 64-bit using MinGW64 from Cygwin.

    export CC=x86_64-w64-mingw32-gcc.exe
    export CXX=x86_64-w64-mingw32-g++.exe
    export LD=x86_64-w64-mingw32-ld.exe

I have, also, modified my PATH to use the appropriate 64-bit bintools and aliased gcc, g++ and ld to the 64-bit MinGW64 compilers and linkers.

To build Boost I have used the following with no success.

   boostrap.sh  address-model=64 -prefix=<install> --with-libraries=thread; bjam -a install;
   boostrap.sh  -prefix=<install> --with-libraries=thread; bjam -a address-model=64 install;
   boostrap.sh  -prefix=<install> --with-libraries=thread; bjam -a install;

The last build attempt succeeds but appears to have built 32-bit binaries. The previous two fail in building boost-threads complaining that 'address-model-64' is not found for certain build artifacts.  I have, also, tried the above with a prebuilt bjam with the same results.

I have tried much more than what I have cited here (including MSVC builds) with no success (some built but resulted in 32-bit binaries). I have scoured Google and found many talking about this but most either had no resolution or contained instructions that conflicted or made no sense. Does anybody have any insight into how I can produce a 64-bit boost-threads archive? Any help would be greatly appreciated.

Thanks in advance,
Dustin

P.S. If I have missed any information or you need more (build logs are too big to attach), please, let me know.
