complex.h: present but cannot be compiled
zieglerk
I am running OpenSUSE 11.1 and had problems with the last binaries (or
at least, that's what I am assuming for the moment), so I want to
build
sage from source. I checked all dependencies given on
http://www.sagemath.org/doc/installation/source.html
Still, ``make'' fails and the first warning -- along with the request
to
report it -- is given below.
configure: WARNING: complex.h: present but cannot be compiled
configure: WARNING: complex.h: check for missing prerequisite
headers?
configure: WARNING: complex.h: see the Autoconf documentation

To me this looks like you do not have g++ installed. I googled it and
it seems that the relevant package to install is called 'gcc-c++'. Can
you try to install that with your package manager?
Best,
Alex

I believe you have found a bug in the prereq script, as this is
indicating you are mixing GNU and non-GNU compilers, which I doubt
could happen on Suse. That test was put in place for systems like
Solaris, HP-UX, AIX etc where compilers from Sun, HP or IBM may be
present in addition to the GNU compilers.

After installing the package gcc-c++ everything compiled smoothly.
The problem was, that with OpenSUSE installing the package gcc (as
mentioned on http://www.sagemath.org/doc/installation/source.html)
does not automatically install gcc-c++, too. (This is possibly
trivial for people who are familiar with gcc or maybe a deficit of
OpenSUSE?)
So, thank's for the quick help.

Could you please post the first part of your log file, where this faillure occured?
It is good you have solved this, but I would dearly like to change the
perquisite checks for Sage to ensure that g++ is present and working. Knowing
exactly what when wrong with your build would really help this.

Glad to hear it worked for you.

A lot of Linux distributions have their quirks, so it's often impossible
(or useless) to give precise generic instructions in regards to
prerequisites, etc. It might be good for us to collect these
distribution-specific issues and put them, for instance, on the wiki.
