Msvc 2010 build problems

GNU Radio
1

Hello,
I made an attempt to compile the actual git master branch with MSVC2010
under win 7.
There some issues which I want list as follows. (Sorry for some german
compiler
messages, but I think there are self explanatory.)

It would be fine if gnuradio can also be builded by MSVC compiler in the
future as we had in the past.

Thanks,
Dietmar

This is a known issue with log2() and ‘not’, ‘and’, ‘or’ macros - see

Also known problem, msvc can only make init in cc file, not in header
file. - see:

prob 3

Seems volk_malloc doesn’t need pthreads because msvc using windows
threads. The include is new compared to version 3.6.5.1.
#ifdef would be sufficient.

new compiler error, has worked under 3.6.5.1

As follows is a link problem. qwt.lib version (using qwt 6.1.1) is in
the link list and was formerly used to build version 3.6.5.1 successful.
It seems that the decoration of the imported functions has changed.
