[SOLVED] Errors compiling BFGMiner under Windows (MinGW 4.8.1)

Hello,

I'm having a hard time compiling bfgminer under Windows x86 and x64 environments with MinGW 4.8.1.
There are a few things that are now a bit outdated in bfgminer git's windows build instructions. But anyway, here's what is going on:

1. mingw-get-inst-xxxxxxxx.exe is no longer maintained, although you can still get a copy from different places on the net.
The new version is mingw-get-setup.exe, which I personally find worst than the previous installer, minor detail anyway, I still went ahead and installed exactly as instructed, through mingw-get-inst-20120426.exe.

2. From there on, I followed every step of the instructions without a hitch... until bfgminer compilation itself.

3. Next step:

Code:

CFLAGS="-O2 -msse2" ./configure

outputs these errors as a result:

Quote

checking for pthread_cancel... no
checking for pthread_create... no
configure: error: Could not find pthread library - please install libpthread

4. Now, getting pthread installed in MinGW... (not mentioned in the current build instructions)

Code:

mingw-get install pthreads

OK, this does the trick and the configuration is now able to proceed.

5. Now onto making...

Code:

make

...returns several errors related to missing header files.
In the 10+ times I tried compiling this program, under several builds of Windows, both x86 and x64, I have had this happen every time and not once is it mentioned in the build instructions, maybe something changed in the code since then, I don't know. Example:

Quote

miner.h:31:22: fatal error: blkmaker.h: No such file or directory
#include <blkmaker.h>

blkmaker.h is located under bfgminer\libblkmaker, this is getting weirder by the second.

6. At this point I start adding libraries to the make command:

Code:

make CFLAGS="-Ilibblkmaker"

Despite that, it still gives me the finger a few steps bellow:

7. The build instructions mentioned libusb as optional, but it seems is now mandatory.
After installing libusb, I get another missing header file:

Quote

lowl-vcom.c:53:22: fatal error: usbioctl.h: No such file or directory
#include <usbioctl.h>

8. The only places in my MinGW installation where usbioctl.h is present are:

C:\MinGW\include\ddk
C:\MinGW\mingw32\include\ddk

Since usbioctl.h in both of those folders is identical, I tried including one of their destinations in CFLAGS:

Code:

make CFLAGS="-Ilibblkmaker -IC:/MinGW/include/ddk"

...which unfortunately breaks on me once again:

I'm at loss here...
I followed the steps in the build instruction flawlessly and even got pthread libraries installed but I can't seem to compile it.

If anyone has any ideas about why this won't compile, I'm all ears!
Thanks.
