Hi,
I tried to install gnuradio on fedora 17 following the instructions at gnu.org. I tried using build-gnuradio install script but it gave "make failed" error at the end. Then I tried using yum install gnuradio but i again failed.
Now i want to rebuild it but before that do i need to delete some files or use some uninstall commands.

Please suggest


Regards
Fabe

well what were the gcc errors ?
A guess it has something to do with fedora 17 and gcc 4.7
and wre you fallowing the build guide ?
http://gnuradio.org/redmine/projects...iki/BuildGuide

what were the yum errors ?
from the install instructions
http://gnuradio.org/redmine/projects...i/InstallingGR

Thanks for your suggestions
Meanwhile I had again tried using buid-gnuradio given at http://gnuradio.org/redmine/projects...i/InstallingGR
But this time it is showing following at the end:
Building Gnu Radio...
...Doing cmake
...Cmaking

you do not appear to have the 'rtl-sdr' directory
you should probably use ./build-gnuradio gitfetch to fetch the appropriate
files using GIT

What to do now.

fedora dose not use "sudo" by default ( was felt to be a big security risk and not used)
the default state is off and unset

to use "sudo" you need to configure it

visudo is in the fedora repos but should not have been installed by default ( might be ? might be installed but turned off )
you need to install it and configure sudo

or
manually configure sudo

see the fedora docs or this one for fedora 15 ( same for 17 )
http://fedorasolved.org/post-install-solutions/sudo
or this one
http://www.server-world.info/en/note...itial_conf&f=7
or the older fedora wiki
