Hello,

I know ther have been billions of questions about LFN, c++ programs
compiling, lstdcxx, etc.

BUT, I still encouter this problem. (By the way, don't you think it's not a
pure hazard if almost everyone encounters this problem ?)

I read section 8 of the FAQ, and checked DJGPP.ENV. In fact, I no longer
encounter the -lstdcxx error message (a big step). Instead, I encouter the
following surprising errors when I try compiling within RHIDE, although I
downloaded evreything correctly :

Error: c:/djgpp/lib/libstdcxx.a(iostream.o)(.text+0x1b9d):iostream.cc:
undefined reference to `__rtti_class'
Error: c:/djgpp/lib/libstdcxx.a(iostream.o)(.text+0x1cdd):iostream.cc:

Error: c:/djgpp/lib/libstdcxx.a(filebuf.o)(.text+0x4f):filebuf.cc: undefined
reference to `__throw'

There are many more lines like this. If I understand well, the linker finds
libstdcxx.a, but disagrees with it --> what can I do since it is the correct
file ?

In fact, when I use the command line
    g++ hello.cpp -o hello.exe
I get the exspected hello.exe file without any error.

Does someone have an explanation ?

Here is the code :

#include <iostream.h>
int main()
    {
    cout << "Hi everybody !";
    return 0;
    }
