Package installation - can't find header files

[charles reid]

Hi -

I'm trying to install the symbolic package.  When I run the 'pkg install symbolic-1.0.9.tar.gz' command from Octave, I see this:

octave-3.2.0:1> pkg install symbolic-1.0.9.tar.gz
symbols.cc:37:25: error: ginac/ginac.h: No such file or directory
ov-vpa.h:39: error: ‘GiNaC’ has not been declared
ov-vpa.h:39: error: expected ‘,’ or ‘...’ before ‘&’ token
ov-vpa.h:39: error: ISO C++ forbids declaration of ‘numeric’ with no type
[etc...]

There are a bunch of errors that are all caused by that ginac.h file not being included.  My Ginac was installed OK, and I see ginac/ginac.h where it's supposed to be:

[~/pkg/ginac-1.5.3/include/ginac] $ ls ginac.h
-rw-r--r--@ 1 charles  staff   1.9K Oct 20 20:41 ginac.h

I set my PKG_CONFIG_PATH to include the Ginac package config file, in ~/pkg/ginac-1.5.3/lib/pkgconfig.  I can't figure out why octave isn't finding the header file.  Is there an octave-specific environmental variable that I can set to point Octave to this header file?


Thanks,
Charles
