We had some problems to install Gecode on our new parallel computer
with Intel Compiler 64 bits which crash when compiling the library :
icpc -I. -I. -DNDEBUG -fPIC -ggdb -O3 -fno-strict-aliasing -DNDEBUG
-fPIC -ggdb
-O3 -fno-strict-aliasing \
-c -o gecode/int/var/imp.o gecode/int/var/imp.cc
../gecode/kernel/core.icc(1605): error #1556: conversion from inaccessible
base class "Gecode::ActorLink" is not allowed
t[0] = static_cast<Propagator*>(f[0]->prev());;
which is an internal error of the compiler. According to the c++ expert
from Intel the program is not c++ standard conforming.
So, to install the library we must modified the class Space as :
--- ./gecode/kernel/core.icc 2007-06-12 17:14:48.000000000 +0200
+++ ./gecode/kernel/core.icc-save 2007-06-12 17:14:43.000000000 +0200
@@ -402,7 +402,7 @@

- class Actor : public ActorDeleteLink {

public:
If someone have to install Gecode onto this architecture it could be
usefull.
