Re: Why does preferences file get installed in /usr/local despite setting custom install prefix?

[Cinaed Simson]

Hi Wan - this path

  /home/..

is not your home path - or your home directory.

Type

  cd /home/..

and then

  ls

and see if you find the gnuradio directory. If you didn't have root privilege at the time then the install failed.

Assuming your userid is

  wan

then

  /home/wan

is you home directory..

What operating system and version are your running?

Hi Cinaed and Neel,

Thanks for your quick response.

My custom prefix is /home/<my path>. I was just shortening it with "/home/...", sorry for the confusion.

I followed a similar process as in the app note.

I ran $ cmake-gui ../ in the build directory.

Then I used the GUI to configure and generate the flags CMAKE_INSTALL_PREFIX, UHD_DIR, UHD_INCLUDE_DIRS, and UHD_LIBRARIES. I also set PYTHON_EXECUTABLE to usr/bin/python3.8

For good measure, tried to build again, this time I can ran

$ cmake -DCMAKE_INSTALL_PREFIX=/home/<my path> -DUHD_DIR=/home/<my path>/lib/cmake/uhd -DUHD_INCLUDE_DIRS=/home/<my path>/include -DUHD_LIBRARIES = /home/<my prefix>/lib/libuhd.so -DPYTHON_EXECUTABLE=/usr/bin/python3.8 ../

The preferences file is still installed to /usr/local

Here's the full gnuradio-config-info output after second attempt

/home/<my path>
/home/<my path>/etc
/usr/local/etc/gnuradio/conf.d
/home/<user>/.gnuradio
