enhanced librtlsdr for RTL_SDR dongle

[w6sz]

Hello Leif,

Still trying to get a dongle to work.

The linrad installation and ./configure(s)  are running fine up to the point that I need to install the librtlsdr ( lin04.07 )

 Not present: librtlsdr.so 
 This package is needed for the Realtek RTL2832 based DVB dongle
 Modern Linux distributions may have a librtlsdr-dev(el) package
 You may install the standard osmocom package from source
 http://sdr.osmocom.org/trac/wiki/rtl-sdr
 To get the improved library for Linrad use the following commands:
    cd /usr/src
    rm -r -f librtlsdr
    wget http://sm5bsz.com/linuxdsp/hware/rtlsdr/rtl-sdr-linrad5.tbz
    tar xvfj rtl-sdr-linrad5.tbz
    cd librtlsdr
    mkdir build
    cd build      ( Everything progressing fine up to cd /build.)
    cmake ..     
    make
    make install

--------------

the cmake does not seem to do anything,  needs cmake  unknown  for me at least

see cmake using in /build

  Unix Makefiles              = Generates standard UNIX makefiles.

root@raspberrypi:/usr/src/librtlsdr/build# ls
root@raspberrypi:/usr/src/librtlsdr/build# 

the result up to here is an empty /build

make 

and make install 

both unknown  No action

Not sure this is the problem, but probably part of the problem''

Sorry Leif for all the hassle.
I really like getting that dongle to run again as before I had to redo the Rasppi

Oooh!!!

The command is "cmake .."
The two dots are essential, they mean run cmake on the
parent directory.
