[SOLVED] std::cout and gfortran print*, don't output to the screen
I am not sure where to post this other than here.
I am trying to figure out why an app gives different output when compiled under Ubuntu 10.10 and CentOS 5.5. I am pretty sure that the issue is that the Cent version has gcc 4.1 installed, while Ubuntu has gcc 4.4. I am trying to print from some fortran code using print*, as I have always done, but nothing appears on the terminal. I don't know how to debug this if I can't print any intermediary output.
I also tried std::cout << from inside the cpp code, but that doesn't do anything either. There aren't any compiler errors or warnings, so what did I miss?
Any suggestions???

cxref-cpp
cxref-cpp(1) General Commands Manual cxref-cpp(1)
NAME
cxref-cpp - A modified C preprocessor to use with cxref.
SYNOPSIS
cxref-cpp ...
DESCRIPTION
To improve the output that is available for the source code for cross-referencing a modified version of the GNU CPP v2.7.2 is supplied
(named cxref-cpp).
This modified C preprocessor allows for a finer control over some features of the preprocessing that are not important for a compiler. In
a standard preprocessor, the preprocessor directives are intended for use only by the preprocessor, so passing the information through is
not important.
With cxref-cpp, there are some features that are different to the standard GNU CPP:
Compared to gcc versions earlier than version 2.8.0 there is an extra option that will output the #include lines from the source
file. In version 2.8.0 and later this option is present.
Comments trailing a #include or a #define are not preserved by all versions of gcc even if the -C option is used. This is not
important while compiling, but is useful for documenting.
The cxref-cpp program will take on the personality of the installed version of gcc so that the gcc header files can be parsed. This
means that it includes the same default include directory paths and macro definitions. The file that contains these definitions is
called cxref-cpp.defines and is installed by the cxref-cpp-configure program or specified by the -cxref-cpp-defines command line
option.
OPTIONS
The same as for gcc, apart from '-cxref-cpp-defines' described above.
