- Hello,
-
- I've tried this question in comp.unix.aix and gnu.g++.help and have gotten
- no responses, I really hope someone here can help me.
-
- First off I am running AIX3.2 on an RS6000.
- I am using gcc 2.3.2/libg++ 2.3
- I am using gdb 4.7
-
- I am having problems debugging c++ programs with gdb4.7.
- gdb seems to work OK on small C programs compiled with gcc but I am
- having problems debugging C++ code compiled(-g of course) with g++.
-
- I should mention that my sys-op says the RS6000 assembly patch(for gcc) has
- been applied. Here is an example of what happens when I try to load a
- executable:
- ------------------------------------------------------------------------

- (gdb) file monte
- Reading symbols from monte...GDB Error: `.bf' not found.
- GDB Error: `.bf' not found.
- done.
- (gdb)
- ------------------------------------------------------------------------
-
- And here is the same thing for what is a simpler program:
-
- ------------------------------------------------------------------------
- cithe502:flux > gdb
- GDB is free software and you are welcome to distribute copies of it
- under certain conditions; type "show copying" to see the conditions.

- (gdb) file flux
- Reading symbols from flux...GDB Error: `.bf' not found.
- GDB Error: `.bf' not found.

- Catastrophe in realloc: invalid storage ptr
- IOT trap (core dumped)

-
- In addition, the first program, which it allows me to load, starts in the
- middle of the routine if I tell it to "break main". It sets the
- breakpoint 17 lines down into routine.
-
- Here is the source code for the second very simple program:
-
- ************************************************************************
-
- #include <iostream.h>
- #include <iomanip.h>
- #include <math.h>
-
- const double E_BREAK = 2.0e6;
- const double K1 = 2.7e4;
- const double K2 = 4.3e6;
- const double GAMMA1 = 2.65;
- const double GAMMA2 = 3.00;
-
-
- /* This program produces a muon flux */
-
- main ()
-
- {
-
- double dN_dE; /* number/m^2*s*sr*Gev */
- double flux;
- double energy; /* in GeV */
- double gamma;
- double K;
-
- for (energy=1e5; energy<1e9; energy = energy*pow(10.0,1.0/10.0))
- {
- if (energy <= E_BREAK) {
- dN_dE = K1*(1.0/(1-GAMMA1))*pow(E_BREAK,1.0-GAMMA1);
- dN_dE = dN_dE + K1*(1.0/(GAMMA1-1))*pow(energy,1.0-GAMMA1);
- dN_dE = dN_dE + K2*(1.0/(GAMMA2-1))*pow(E_BREAK,1.0-GAMMA2);
- }
- else {
- dN_dE = K2*(1.0/(GAMMA2-1))*pow(energy,1.0-GAMMA2);
- }
-
- flux = dN_dE*72.0*12.0*PI*60.0*60.0*24.0*356.0 ;
-
- cout.setf(ios::scientific);
- cout << setprecision(3) << energy << " " << flux << endl;
- }
- }
-
- ************************************************************************
-
- Also I'm not sure if this is relevant but I get the following warning
- message when I compile the above code -g:
-
- cithe303:flux > g++ -lm -g -oflux flux.cc
- /usr/local/lib/g++-include/iomanip.h: In function `class smanip<int> setbase (int)':
- In file included from flux.cc:2:
- /usr/local/lib/g++-include/iomanip.h:141: warning: dbx info for template class methods not yet supported
- cithe303:flux >
-
- ************************************************************************
- Any suggestions would be most appreciated!
