error when compiling xdrawchem

[Jan Lentfer <Jan.Lentfer@web.de>]

Hi list,

I am trying to build a new package for xdrawchem (1.7.2). I got it build fine on
x86, but it fails to build on Alpha.

It fails with:

g++ -DHAVE_CONFIG_H -I. -I. -I..   -I/usr/X11R6/include -I/include
-I/usr/include/qt -I/usr/X11R6/include/qt -I../openbabel -DUNIX
-DRINGHOME="\"/usr/local/share/xdrawchem/\""
-DXDC_SERVER=\"herger.ibb.gatech.edu\"  -g -c -o arrow.o `test -f 'arrow.cpp' ||
echo './'`arrow.cpp
arrow.cpp: In method `class QPoint Arrow::Midpoint()':
arrow.cpp:165: implicit declaration of function `int lround(...)'
make[2]: *** [arrow.o] Fehler 1

Any ideas anyone?

TIA,
