Thank you for your reply Anton. I'm sorry it's taken a while to get
back to you. This binutils came with the MinGW installer. I have made
some progress by reinstalling according to these instructions, though
I took slightly more recent versions in some cases and also found I
needed Perl (thank you Anton and Ted):

Now I can compile and install llvm-2.4 but the first step in the
tutorial fails for me with another missing symbol:

$ g++ -g tut1.cpp `llvm-config --cxxflags --ldflags --libs core` -o tut1
/mingw/lib/libLLVMSystem.a(Process.o):Process.cpp:(.text+0x8d):
undefined reference to `GetProcessMemoryInfo at 12'
collect2: ld returned 1 exit status

I'm using GNU ld (GNU Binutils) 2.18.50.20080109.

Thanks for any further help you can provide,

Duncan Pierce

I believe you will need additional libraries like imagehlp and psapi.

I have /lib/libimagehlp.a  and /lib/libpsapi.a

nm --defined-only /lib/libpsapi.a | grep "GetProcessMemoryInfo" -

returns:

00000000 T _GetProcessMemoryInfo at 12
00000000 I __imp__GetProcessMemoryInfo at 12

And llvm-config seems to be asking for them to be picked up:

-I//include  -D_DEBUG  -D_GNU_SOURCE -D__STDC_LIMIT_MACROS -O2
-fomit-frame-pointer  -Woverloaded-virtual
-L//lib  -lpsapi -limagehlp -lm
-lLLVMCore -lLLVMSupport -lLLVMSystem

So I'm still mystified.

Best regards,
Duncan
