Hey,

I picked up your message off of the djgpp archives.  I was wondering if
you were still having the problem?  I was having the same problem as you,
compling and linking over and over agian just to get the same 'undefine'
error messages.

But if its still of use to you strangely in my depesperation in tinkering
I use this command line:   gxx -Wall -o test.exe mode13.cpp asmfunc.o
-lgpp

I don't know why this was special and linked perfectly when every other
way I attempted failed.  I used both gxx.exe and gcc.exe before.  I hope
this helps anyone else at all in figuring it out.

------------------------------------------
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:
undefined reference to `__rtti_class'
Error: c:/djgpp/lib/libstdcxx.a(iostream.o)(.text+0x1f4e):iostream.cc:

undefined reference to `__rtti_user'
Error: c:/djgpp/lib/libstdcxx.a(filebuf.o)(.text+0x46):filebuf.cc:
undefined
reference to `__eh_pc'
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;
    }
