Re: [igraph] Installing igraph on Solaris

[Jens Pfau]

After getting rid of igraph_logbl, I can compile the library with the
newer GCC without getting any assembly error. However, I do still get
the linking error when using the lib. Maybe you know what might be the
problem?

Some other things I had to modify to be able to compile the source on Solaris:
I had to change the suffixes of all files that include cs/cs.h from .c
to .cpp such that they are compiled by g++ and not gcc because gcc was
unable to include complex.h (even though it is present in the
compiler's include directory). I tried to change the include
declaration to different versions without success but I do not want to
rule out that this could have been solved in a much simpler way.

In bignum.h I changed the include of pstdint.h to sys/int_types.h.
Probably because of that there appeared a conflict between the
definition of cnt_t and a system definition. I changed the name of
this both in bignum.h and bignum.c.

The function sqrtf does not exist on Solaris. As far as I remember I
changed the call to sqrt() somewhere.

logbl is called in bliss_bignum.hh, so I cannot compile without it. I
changed the call to logb() but maybe it would be better to provide a
working implementation of igraph_logbl.
