[CLN-list] CLN compile errors on GCC4.2

[Vipin Varma]

Hi

Thanks for the replies.

@Alexei:
This is the OS and gcc that I use:

>>>>>>>>>>>>>>>>>>>>>>>>>

Using built-in specs.
Target: i486-linux-gnu
Configured with: ../src/configure -v 
--enable-languages=c,c++,fortran,objc,obj-c++,treelang --prefix=/usr 
--enable-shared --with-system-zlib --libexecdir=/usr/lib 
--without-included-gettext --enable-threads=posix --enable-nls 
--with-gxx-include-dir=/usr/include/c++/4.2 --program-suffix=-4.2 
--enable-clocale=gnu --enable-libstdcxx-debug --enable-objc-gc 
--enable-mpfr --enable-targets=all 
--enable-checking=release--build=i486-linux-gnu --host=i486-linux-gnu 
--target=i486-linux-gnu
Thread model: posix
gcc version 4.2.4 (Ubuntu 4.2.4-1ubuntu3)

>>>>>>>>>>>>>>>>>>>>>>>>>>

And the include portion of the graph.cpp:

<SNIP>
#include <cmath>
#include <iostream>
#include <iomanip>
#include <sstream>
#include <map>
<SNIP>

@Bruno:

When I give the compiler-option of just -I/users/varma/cln-1.3.1/include 
and 
not -I/users/varma/cln-1.3.1/include/cln, the compiler is unable to find 
the header files which are in include/cln:

rational.h: No such file or directory
ES_lattice_temp.cpp:13:25: error: rational_io.h: No such file or directory
ES_lattice_temp.cpp:156: error: integer constant is too large for âlongâ 
type
ES_lattice_temp.cpp:156: error: integer constant is too large for âlongâ 
type
ES_lattice_temp.cpp:28: error: cln is not a namespace-name
ES_lattice_temp.cpp:28: error: expected namespace-name before ; token
In file included from BHH_Nsite_final.cpp:12,
                  from ES_lattice_temp.cpp:34:
CoulombEnergy.cpp:1: error: cl_RA was not declared in this scope
CoulombEnergy.cpp:1: error: template argument 1 is invalid
CoulombEnergy.cpp:1: error: template argument 2 is invalid

......and more errors ......

I am wondering how to make the compiler just pick up the relevant header 
files from include/cln ...

Regards,
Vipin
