Build error

[MatthewWhiting]

Hi Matthew,

I'm trying to build Duchamp so I can run it on some simulated radio cubes, but I'm getting an error which I can't fathom. If you get a minute could you please take a look?

The system is running Ubuntu 10.04 64-bit.

I have attached the output of 'make' below. From what I can gather the first time it invokes gcc results in a line break and then a mysterious lone 'o', immediately after pgplot_related.o.

Thanks in advance for your time

-Ian

Adding email from Ian Heywood as ticket.

Gday Ian,

That is indeed a strange one that I haven't come across before. (I've added it as a ticket to my Trac system for future reference, and to make it easier to track these sort of problems)

What appears to be the problem is that the configure script has not found a fortran compiler - this is needed to do the linking when pgplot is included. If you like you can attach the config.log and Makefile to this ticket so I can have a look at what's going on.

If you know where the fortran compiler is (it appears it's in a somewhat non-standard location, else configure would have found it), you can run

./configure F77=<path-to-compiler>

Ideally this should be the same that was used to build pgplot (if you know what that was...)

Alternatively, you can do

./configure --with-pgplot=no   

so that it won't include pgplot and so do the linking with g++. You'll of course lose all the nice graphical stuff, so the first option is better.

I'm a bit puzzled as to the lone 'o', but it may be just how the -o flag for the linker works out when there's no compiler given...

Cheers, Matt.

Update from Ian:

Hi Matt,

Thanks for the quick response. It turns out that I didn't have f77 installed at all.

> sudo apt-get install fort77

fixed this.

It then grumbled about libf2c

/usr/lib/libf2c.so: undefined reference to `MAIN__'
collect2: ld returned 1 exit status

but a quick Google search revealed this:

> sudo rm /usr/lib/libf2c.so
> sudo ln -s /usr/lib/libf2c.a /usr/lib/lib2c.so

which I tried, as usual without considering whether that was sensible or not, and everything worked out fine.

No errors! Everything is working fine.

Just out of interest, what's the largest cube you've processed with Duchamp?

Thanks for sharing your software.

Cheers
-Ian

Closing ticket.
