I have got some problems with rootcint. I am using root version 5.22.0 on Ubuntu 8.10 (gcc 4.3.2). Whenever i try to generate dictionaries, I get the following error message:
rootcint -f BMS_RootDict.cc -c -I/opt/root/include -I/home/bastian/institut/geant4/bms/simulation/include -I/opt/geant4/9.2/include -I/usr/include BMS_Root.hh Linkdef.h

I am using Scientific Linux 4, gcc version 3.4.6 and root_v5.22.00.Linux.slc4.gcc3.4.tar.gz.
First, this post help me to solve my problem, but it is not a good solution (in my mind).
I got the same problem compiling a program with rootcint using -I/usr/include
Unfortunately, the program I used needed the log4cxx header and library that I had installed (long ago) in /usr/include and /usr/lib directories. And off course, when I used rootcint … -I/usr/include … , I got the same problem. I solved it by creating a new directory and by copying all the headers in this new directory. But I think that is not a good solution to solve that problem. And it will be nice this bug is fixe in future.
Note that I used root v5.20 et gcc.4.4 on apple Os X 10.5
hello!
I have read the content above, but still I can not solve my problem.
My system is Ubuntu 8.10,
My gcc version is as follows:
Using built-in specs.
Target: i486-linux-gnu
Configured with: …/src/configure -v --with-pkgversion=‘Ubuntu 4.3.2-1ubuntu12’ --with-bugurl=file:///usr/share/doc/gcc-4.3/README.Bugs --enable-languages=c,c++,fortran,objc,obj-c++ --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++/4.3 --program-suffix=-4.3 --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 4.3.2 (Ubuntu 4.3.2-1ubuntu12)
I use the ’ apt-get install rootsys ’ to install the root on my machine, the version is 5.18/00b
I wirte a small code:
[code]#include <stdio.h>
#include <iostream.h>
#include “iomanip.h”
#include<fstream.h>
gROOT->Reset();
void a()
{
A1 = new TH1F(“A1”,“A1”,100,0,4100);
A1->Fill(50);
TCanvas *c1 = new TCanvas(“c1”,“c1”,0,0,780,600);
c1->cd();
A1->Draw();
c1->Print(“A1.ps”);
cout<<“This is A1”<<endl;
}[/code]
When I run this code using ’ root a.C ', it is all right.
However, if I use:
$ g++ -L/usr/lib/root -I/usr/include/root a.C
it displays:

a.C:3:21: error: iomanip.h: No such file or directory
