Another question about making a signal processing block

GNU Radio
1

Hi,

I was trying to make a signal processing block. I basically did
nothing but copied the ``how-to-write-a-block’’ package and modified
the name of the block in files according to the Shen tutorial.With the
help from Philip, I got around several make problems I asked earlier.
The automake passes with two messages that do not seem to be bad:

[root@wlab02 trytry]# automake
doc/Makefile.am:77: %'-style pattern rules are a GNU make extension doc/Makefile.am:80:%’-style pattern rules are a GNU make extension

But make is giving me problems. It seemed to be complaining about not
being able to find “fvirtual”, therefore the no zzblk.cc is produced
and g++ cannot find the source file to compile. The detailed messages
are the follows. Any hint is greatly appreciated. Thanks!

The shell environment variable CC isn’t getting picked up properly by
configure, or it is not correctly defined in your shell environment.

Thanks for the help! I will check it.

automake has been complaining about not being able tofind PYTHON
variable:

src/lib/Makefile.am:55: Python sources seen but `PYTHON' is

undefined

After adding `AM_PATH_PYTHON’ micro to Makefile.am, automake does not
complain any more. I actually don’t think I should be doing this
because it should be automatically done, I guess. The missing of the
CC variable may due to the same problem.

Thanks again for the help!

What versions of automake and autoconf do you have?

$ autoconf --version
$ automake --version

OK, those look fine.

Try this:

rm -fr config.cache autom4te*.cache

aclocal -I config
autoconf
autoheader
libtoolize --automake
automake --add-missing -c -f -Wno-portability

./configure
make && make check

[I realized that we’re not distributing the “bootstrap” script with the tarballs. I’ll fix that in a minute.]

Eric,

Thanks so much! I will try them first time tomorrow morning.

Eric,

Thanks a lot for the help. I tried your commands and it is working
now. I can build a signal processing block and run qa tests. Thanks so
much.

It took me a while to because there were some bugs in my files.
