Don't worry about. I think I understand the problem. I fix will be
pushed later today to the maint and master branches. Just update your
source tree and rebuild uhd. Or if you used the build-gnuradio script,
just re-run that script.

Subject: [USRP-users] Building From Source (MSVC 2010 32bit) Run Time
Errors
Message-ID:
<4b5c436558dc844f812ed62cdb7689690f7f9...@exchmbx03.fed.cclrc.ac.uk>
Content-Type: text/plain; charset="us-ascii"
Hello
I keep getting runtime errors with the example .exe files built in release mode
from source. However, if I build the files in debug mode then they work without
error.
I am using microsft visual studio 2010 on windows xp (32 bit) to build the
master branch from the git repo. for my N200 device.
I have followed the instrucitons in your build guide (installed dependies etc)
and have tried assembling the msvc UHD.sln file using the CMake options as
shown in http://dl.dropbox.com/u/56452610/CMake%20Options%201.PNG and
http://dl.dropbox.com/u/56452610/CMake%20Options%202.PNG .
The log from configuring and generating the files is here
http://dl.dropbox.com/u/56452610/CMake%20Log.txt.
When I then set the mode to release and build I get the following log:
http://dl.dropbox.com/u/56452610/MSVC%20build%20log.txt
Taking tx_bursts.exe as an example, when I run it the console gets as far as
"Creating the usrp device with:.." and then I get a debug assertion error
(http://dl.dropbox.com/u/56452610/Assertion%20Error.PNG ).
Other example .exe's just go straight to the standard windows "xxxxx has
encouterd a problem" message.
Any help would be much appreciated.
Cheers
John
