Hello everyone, I am just getting started with software defined radio (Ettus E320) for work/school and am trying to install UHD on Windows 10. I have followed the instructions on the ettus knowledge base website, and even though everything seems to install fine, I get some warnings in CMake and then similar errors when I attempt to run executables, so something must have gone awry. I may eventually backup my computer and switch everything over to dual boot in Linux to make this easier, but I thought I’d try to get it working in Windows a little longer first. TL;DR version: If I try to run UHD\bin\uhd_config_info.exe (or uhd_find_devices or any other executable) I get the error "The code execution cannot proceed because libusb-1.0.dll was not found. Reinstalling the program may fix this problem." I have tried moving the libusb files to different locations, using different versions of UHD/libusb, and recompiling everything, but the same message appears. LIBUSB_INCLUDE_DIRS is set to 'C:/libusb-1.0.23/include/libusb-1.0 ' and LIBUSB_LIBRARIES is set to 'C:/libusb-1.0.23/MS64/dll/libusb-1.0.lib' in CMake and the dll is in the same directory as the lib file. More details: I have Windows 10, Visual Studio 2019, msvc 14.2, libusb 1.0.23 (also tried 1.0.22), cmake 3.18.2, boost 1.73, and python 3.8.5. I use Ubuntu-WSL for communicating with the E320 and have not had any issues doing that. I run everything as an administrator and use WSL to run executables with the sudo command, so I don’t think file access is the issue. I have mostly been trying to use UHD 3.15.LTS to get it to work. In CMake I get the warnings and missing packages included below. There are some references to libusb in the CMake log files as well and can include those outputs if they will help. The installation in Visual Studio seems to run fine, but if I try to run C:\Program Files (x86)\UHD\bin\uhd_config_info.exe (or uhd_find_devices or any other executable) I get the error "The code execution cannot proceed because libusb-1.0.dll was not found. Reinstalling the program may fix this problem." LIBUSB_INCLUDE_DIRS is set to 'C:/libusb-1.0.23/include/libusb-1.0 'and LIBUSB_LIBRARIES is set to 'C:/libusb-1.0.23/MS64/dll/libusb-1.0.lib' in CMake. I have tried it with the location ‘C:\Users\myusername\libusb-1.0.23\…’ as well, but got the same problem. The CMake output is below. Hopefully that was enough information to at least get started on solving this, if I’m missing any important details please let me know, and thanks in advance!
