[Discuss-gnuradio] RE: Discuss-gnuradio Digest, Vol 85, Issue 30

[汤图杨]

Hi :
    I am  trying to build a new block into the gnuradio, after writing the .h .cc .i files  and making some changes in the makefile.am configure.ac , I type the following command:
  
 
   >> ./bootstrap
 
   the result is :
  doc/Makefile.am:77: `%'-style pattern rules are a GNU make extension
  doc/Makefile.am:80: `%'-style pattern rules are a GNU make extension

  and it seems right,  then I tried the ./configure , and the terminal showed that :
  
  checking for gnuradio-core >= 2... Package gnuradio-core was not found in the pkg-config search path. Perhaps you should add the directory containing `gnuradio-core.pc' to the PKG_CONFIG_PATH environment variable No package 'gnuradio-core' found
configure: error: Library requirements (gnuradio-core >= 2) not met; consider adjusting the PKG_CONFIG_PATH environment variable if your libraries are in a nonstandard prefix so pkg-config can find them.


 I know the environment variable, but i am confused about why it did not show any error when i try to build the gr-how-to-write-a-block
module. and the error block i just tried is something like the example one.


 can anyone give me some suggestions?

 thanks!
