Hi All,  
I have updated gnuradio to 3.7.5 recently, and then reconfig&rebuild  
gr-osmosdr to link its lib against to v3.7.5’s gnuradio-runtime.so.  
But when I import osmosdr, I got below error

ImportError: libgnuradio-runtime-3.7.4.so.0.0.0: cannot open shared  
object file: No such file or directory

And then I run “ldd lib/libgnuradio-osmosdr-0.1.4git.so.0.0.0”, I found  
an interesting thing, this lib link to both v3.7.5 and v3.7.4

hutiantian@build-server:~/workspace/gr-osmosdr/build$ ldd  
lib/libgnuradio-osmosdr-0.1.4git.so.0.0.0

…  
libgnuradio-runtime-3.7.5.so.0.0.0 =\>  
/usr/local/lib/libgnuradio-runtime-3.7.5.so.0.0.0  
(0x00007f54e66b1000)\<-----It found v3.7.5  
libgnuradio-runtime-3.7.4.so.0.0.0 =\> not found\<------but It also link  
against to v3.7.4  
libgnuradio-pmt-3.7.4.so.0.0.0 =\> not found  
…

I have already deleted all v3.7.4’s lib in my “/usr/local”, and after  
run "grep -r -a “3.7.4” in “gr-osmosdr/build”, I didn’t find any string  
about 3.7.4  
I also run “ldconfig” after rebuild.  
I have checked other OOT modules like gr-dvbt, they didn’t have this  
issue.  
Anyone can give me some clues about this issue?

–  
Thanks

Resolved it  
Since my gr-osmosdr dependent on gr-iqbal, but I forgot rebuild it. Need  
rebuild gr-iqbal to let its lib also link against to v3.7.5
