Hi all, I'm trying to debug a C++ program (compiled with gcc 4.1.1) with gdb 6.5-15.fc6rh (on a FC6 x86_64 machine), and I'm experiencing a most vexing problem. I'm breaking the program in a constructor and want to look at the local variables, but gdb says there are no such symbols in the current context. The program is compiled with -g -O0. Here's some code: mcrx::mappings_stellarmodel::mappings_stellarmodel(Preferences& p, const nbody_data_grid& gr) : prefs(p), g(gr), axes(4), middle_axes(4), use_teff(prefs.defined("use_teff") && prefs.getValue("use_teff", bool())) { using namespace boost::lambda; FITS input_file("/home/patrik/mappings/Zmodels.fits", Read ); Array< T_float, 4 > temp; read (input_file.pHDU(), temp); // to get in increasing wavelength order temp.reverseSelf(fourthDim); // and transpose (z, t, 0/1, l) to get axes to be (0/1, t, Z, l) temp.transposeSelf(thirdDim, secondDim, firstDim, fourthDim); int crapass = 4; ExtHDU& axes_HDU = open_HDU (input_file, 1); The details are not important, but as you can see, p and gr are parameters, and input_file, temp, and crapass are local variables. When I stop gdb on the final line, I can do this: 352 int crapass = 4; (gdb) 353 ExtHDU& axes_HDU = open_HDU (input_file, 1); (gdb) p crapass No symbol "crapass" in current context. (gdb) info scope 353 Scope for 353: Symbol this is a variable with complex or multiple locations (DWARF2), length 8. Symbol p is a variable with complex or multiple locations (DWARF2), length 8. Symbol gr is a variable with complex or multiple locations (DWARF2), length 8. As you can see, only the this pointer and the parameters to the constructor are recognized, it's as if the local variables don't exist. They are there, I can step into the calls to their member functions and examine them, but they are missing from the gdb symbol table. If I step up to the overlying stack frames, I can see those variables fine. Does anyone have any idea what could be causing this and how to fix it? thanks, /Patrik J.
