Message-ID: <1330089155.1826.YahooMailNeo@web171508.mail.ir2.yahoo.com>

Hello, tgis is my problem

after download and install libosmore by git and install it ( no soucy)

i go to osmo-tetra/src

I do a make, for compile tetra-rx etc ... ok, no soucy

i make a "tmp" directory

i make the two fifo

mkfifo ./tmp/out.float
mkfifo ./tmp/out.bit

Ok, no soucy for the moment

I have a funcube and i'm launching with these commands

./osmo-tetra/src/demod/python/fcdp-tetra_demod_fft.py -D hw:1,0 -o ./tmp/out.float -L12500 |
./osmo-tetra/src/float_to_bits ./tmp/out.float ./tmp/out.bits |
./osmo-tetra/src/tetra-rx ./tmp/out.bits

Ok the program Osmo-Tetra FCDP"is running but i have an error msg from tetra-rx
./osmo-tetra/src/tetra-rx: error 
while loading shared libraries: libosmocore.so.4: cannot open shared 
object file: No such file or directory"

What is the problem ? i think the librairies are correctly installed

These are the terminal return message

./osmo-tetra/src/demod/python/fcdp-tetra_demod_fft.py
 -D hw:1,0 -o ./tmp/out.float -L12500 | ./osmo-tetra/src/float_to_bits 
./tmp/out.float ./tmp/out.bits | 
./osmo-tetra/src/tetra-rx ./tmp/out.bits
./osmo-tetra/src/tetra-rx:

shared object file: No such file or directory

Most likely that's corrent, otherwise the compiler driver could not have
linked the executable.

        $ sudo ldconfig

should do the trick. That's always necessary after installing libraries.
See the manpage of ldconfig.

Kind regards,
