Compiling pgplot on opensuse 11.1

From: "andrew cooke" <andrew@...>

Date: Wed, 24 Jun 2009 23:23:42 -0400 (CLT) 

In general, follow the instructions given.  Make sure gcc 3.3 and gfortran
4.3 are available.

Once the makefile (with linux g77_gcc) is generated, edit it to:
- remove the dependencies for pndriv.o (png.h etc - a single line which
expects system libs to be in the current working directory for some odd
reason)
- change gcc to gcc-3.3
- change g77 to gfortran

MFDRIV and TXDRIV failed to compile (so I disabled them again in drivers)

To use:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/pgplot
export PGPLOT_DIR=/usr/local/pgplot/

I am very worried about the different versions of the libraries, but the
demo works and I cannot get C code to compile with gcc 4.3 (malloc
argument issue) or fortran code to run with g77-3.3 (s_cat linker issue).


To install KGB's Perl interface, install cpan and ExtUtils and YAML from
Yast, the start cpan and type "install PGPLOT" and it all just works
perfectly.

Theano Experience

From: andrew cooke <andrew@...>

Date: Fri, 2 Jul 2010 17:39:44 -0400 

I used todays source and found:
- a pile of tests failed on install
- it doesn't work with gcc-4.4 (standard on OpenSuse 11.2), despite CUDA 
  working OK
- when I use ggc-4.3 (they describe how to do this), the test says that
  it's using GPU then reports it used the CPU.
- specifying the float type finally fixes that.

Having said that, I could have been a bit smarter and the response to emails
was quick.  You can see the whole thing here: http://groups.google.com/group/theano-users/browse_thread/thread/6b091d02d6260dc1

So looks promising, if still a little raw (understandably) now.

Andrew
