Scons + boost = error?

Hello everyone!

I'm trying to compile freeorion but running into trouble.

Boost 1.34 is installed:

Code:

[matjes@Data FreeOrion]$ rpm -qa | grep boost
boost-1.34.1-13.fc9.x86_64
boost-devel-1.34.1-13.fc9.i386
boost-1.34.1-13.fc9.i386
boost-doc-1.34.1-13.fc9.i386
boost-devel-static-1.34.1-13.fc9.i386

When I run scons in the sourcecode directory freeorion/trunk/FreeOrion I'm getting the following error:

Code:

[matjes@Data FreeOrion]$ scons
scons: Reading SConscript files ...
Configuring for POSIX system...
Checking for Py_Initialize() in C library python2.5... yes
Checking for pkg-config... yes
Checking for GiGiSDL >= 0.6.0... no
Checking for C++ header file boost/shared_ptr.hpp... yes
Checking Boost version >= 1.34... (cached) yes
Checking for C++ header file boost/graph/dijkstra_shortest_paths.hpp... no
Boost configuration... (cached) no

But the file dijkstra_shortest_paths.hpp exists in the inlcude directory:

Code:

[matjes@Data FreeOrion]$ ls /usr/include/boost/graph/dijkstra_shortest_paths.hpp 
/usr/include/boost/graph/dijkstra_shortest_paths.hpp

What am I doing wrong?

Post config.log created by scons.

Okay... here it comes

Seems that there is a missing #include to limits.h (in this file is CHAR_BIT defined). I already did a little google search for the scons function Configure.CheckHeader but didn't found a way to do the necessary #include before testing for the dijkstra header -.-

I hope it can be fixed ^^

CheckHeader can take a list of include files, so it's possible to pass limits.h along with dijkstra_shortest_paths.hpp . But IMO boost should take care of including files that it needs itself..

Hello!

With the list of headers it works... but can i tell scons which compiler he has to use? Because boost isn't compatible with gcc version 4.3.x.
So I have to tell scons to use g++34 instead of g++.

With command line options you can't AFAIK. Either modify SConstruct to set env["CXX"] = "g++-3.4" or switch compiler e.g. with Gentoo's gcc-config.
