Forum: GNU Radio Use of 64-bit libraries

Just starting to get involved with GNU Radio, on Mandriva 2011_x64
1. How do I tell cmake to use 64 bit libraries?
cmake says:
- checking for module 'orc-0.4 > 0.4.11'
--   package 'orc-0.4 > 0.4.11' not found
-- orc files (missing:  ORC_INCLUDE_DIR)
but:
[root@handel lib64]# ls -l|grep orc
lrwxrwxrwx  1 root       root             20 Aug 27  2011
liborc-0.4.so.0 -> liborc-0.4.so.0.14.0*
-rwxr-xr-x  1 root       root         506192 Jun 16  2011
liborc-0.4.so.0.14.0*
lrwxrwxrwx  1 root       root             25 Aug 27  2011
liborc-test-0.4.so.0 -> liborc-test-0.4.so.0.14.0*
-rwxr-xr-x  1 root       root          31152 Jun 16  2011
liborc-test-0.4.so.0.14.0*

2.    How to tell cmake that uhd is installed in /opt:
cmake says:
-- checking for module 'uhd'
--   package 'uhd' not found
-- Could NOT find UHD (missing:  UHD_LIBRARIES UHD_INCLUDE_DIRS)
But
[root@handel lib64]# cd /opt
[root@handel opt]# ls -l|grep uhd
drwxr-xr-x 5 root   root       4096 Feb  4 16:33 uhd/

Thanks

What does 'pkg-config --modversion orc-0.4' return? This is the string
that's compared against the version number. It's likely that you have 
the
libraries installed but not the development version (e.g., the headers).

Again, we use package config to find the installed versions of things 
like
this. You'll have to make sure 'pkg-config --modversion uhd' returns
something valid. Most likely, all you need to do is add
'PKG_CONFIG_PATH=/opt/uhd/lib/pkgconfig' (or where ever the uhd.pc file 
is
located).
