That said, isn't the just-uploaded-to-hwloc-website win64 build enough for you? It contains the libhwloc.a static build in lib/ Samuel
Re: [hwloc-users] Compiling hwloc into a static library on Windows and Linux
COMPILING HWLOC ON WINDOWS WITH MINGW/CYGWIN I've attached the output of make V=1 in make_output.txt. I included the demonstration first of it failing because it can't find the include directory, but I just fix that by copy/pasting the contents of include/ into src/. HWLOC_HAVE_WINDOWS_H is defined to 1 in /include/hwloc/autogen/config.h. I copied the .def file from the official Windows build into .lib and ran the following from inside src/ (after running vcvars32 bat file to set up environment variables local to the terminal): C:\hwloc-1.3.1\src>dolib.exe lib.exe X86 .libs/libhwloc.def libhwloc- .libs/libhwloc.lib This creates a .lib file, but when I use the VS compiler to compile and link against it, it asks for a dll at runtime. I have a couple other things I'll try, but I wanted to get this email off before too long. Also, prior to VS linking my program with hwloc, there are a few errors that crop up: * VS does not know what __inline__ means This is fixed by changing the definition of __hwloc_inline from __inline__ to __inline in include/hwloc/autogen/config.h See: http://msdn.microsoft.com/en-us/library/z8y1yy88.aspx * VS spouts out a whole bunch of errors relating to the definition of __attribute__ and __deprecated__ This is new in hwloc 1.3.1 - just using the header from 1.3.0 does away with all of these errors The generated headers are the same as in the official releases for 1.3.1 and 1.3.0 The error output is attached in the file vs_output.txt COMPILING HWLOC ON WINDOWS WITH VS VS apparently has problems when functions are declared as static inline when using its C compiler. A way around this I've found is to explicitly pass it the /TP flag, which makes it use its C++ compiler. A bunch of errors about the identifier '__attribute__' being a syntax error then pop up, however, and I haven't found a way around those yet. Thanks for all your help so far!

Could you run make V=1 to get the command lines, and check that HWLOC_HAVE_WINDOWS is 1 in ./include/hwloc/autogen/config.h ? At worse, I believe you can just copy the libhwloc.def contained in the 32bit build of the exact same version of hwloc, it should be compatible. Thanks, Samuel

Ah yes, I was misunderstanding the purpose of --enable-embedded-mode. I understand now, and also use the --enable-static and --disable-shared flags. I have been able to successfully compile into only a static library with headers on Linux, but Windows is still giving me some trouble. I've installed MinGW and Cygwin, and specified HWLOC_MS_LIB as the path to the VS lib tool when running configure. Make works just fine (although the include directory isn't set properly, but that's easy to work around) until the Windows library linking stage: C:\hwloc-1.3.1>make Making all in src make[1]: Entering directory `/cygdrive/c/hwloc-1.3.1/src' CC topology.lo CC traversal.lo CC distances.lo CC topology-synthetic.lo CC topology-xml.lo CC bind.lo CC cpuset.lo CC misc.lo CC topology-windows.lo topology-windows.c: In function 'hwloc_win_get_VirtualAllocExNumaProc': topology-windows.c:323:30: warning: assignment from incompatible pointer type [e nabled by default] topology-windows.c:328:28: warning: assignment from incompatible pointer type [e nabled by default] topology-windows.c: In function 'hwloc_look_windows': topology-windows.c:469:36: warning: assignment from incompatible pointer type [e nabled by default] topology-windows.c:470:38: warning: assignment from incompatible pointer type [e nabled by default] CCLD libhwloc_embedded.la copying selected object files to avoid basename conflicts...

But the library is built, it's just not installed because projects often prefer to link the library in, or something similar.
