Re: [Discuss-gnuradio] get GPS time from GPSDO module

[Bastien Auneau]

Hi Nick

We have compiled (in debug mode) the last UHD (3.2.1)
Now there are no "unhandled exception" while querying the sensors
I guess I made a mistake with release/debug mode earlier

Also, I understood that I have to build UHD in debug mode, and that I
cannot use the binary version for windows, while my project using UHD is
on debug mode ? Please confirm/infirm

Also, in case of missing msvcp100.dll, installing Visual C++
redistribution package helps only if you install the x86 (32 bit)
version. Hope this will help someone...

Regards
Bastien
