Re: library files

["Harry Overs" <hovers@dera.gov.uk>]

Hi,

thanks both for replying.

I've checked what you have both suggested and:
1) we are using the gnu gnat compiler
2) the Ada sub programs have got the pragma export designation
3) I believe I have all of the needed source code apart from the common
system files (though as I dont know anything about Ada I cant verify this).

I have continued to persevere with this and going through the gnu
documentation I found out I was actually creating an archive instead of a
library (now following the steps laid out at
http://www.delorie.com/gnu/docs/gcc/gnat_ug_188.html), so I have now change
my build script so that it attempts to create a library instead.  However
I'm now getting errors during the creation of the library (e.g. "undefined
reference to 'system__soft_links__get_jmpbuf_address_soft'").  During my
attempts to solve these errors I've created a dummy Ada program which
contained one method (no main) and one external method (using pragma
export), this program also came up with similar errors when I tried to
compile it into a library.

so can anyone give me any pointers on how to remedy this?

many thanks,
