Package: gdb Version: 6.6.dfsg-1 Severity: normal Consider the following Fortran 90 program.
$ cat using_modules.f90 module dummy implicit none integer :: m = 3 end module dummy program using_modules use dummy implicit none real :: alpha = 0.3 write(*,*) 'm = ', m write(*,*) 'alpha = ', alpha end program using_modules There are two variables in this program : m, alpha. The variable 'm' declared inside the module 'dummy' acts as a global variable inside the program 'using_modules'. However, the value of m cannot be printed when the program is run via gdb. $ gfortran -g using_modules.f90 $ gdb -q ./a.out Using host libthread_db library "/lib/libthread_db.so.1". (gdb) b using_modules.f90:11 Breakpoint 1 at 0x80486c9: file using_modules.f90, line 11. (gdb) r Starting program: /home/rajuonu2/deleteafter/a.out m = 3 Breakpoint 1, MAIN__ () at using_modules.f90:11 11 write(*,*) 'alpha = ', alpha Current language: auto; currently fortran (gdb) p m No symbol "m" in current context. As you can see, we can access the variable 'm' inside the program. But that variable cannot be accessed inside gdb. However, the local variable 'alpha' can be accessed without any problem. (gdb) p alpha $1 = 0.300000012 The problem exists only with variables accessed via modules. hth raju -- System Information: Debian Release: testing/unstable APT prefers oldstable APT policy: (500, 'oldstable'), (500, 'unstable') Architecture: i386 (i686) Kernel: Linux 2.6.17-2-686 (SMP w/1 CPU core) Locale: LANG=en_US, LC_CTYPE=en_US (charmap=ISO-8859-1) Shell: /bin/sh linked to /bin/bash Versions of packages gdb depends on: ii libc6 2.5-7 GNU C Library: Shared libraries ii libncurses5 5.5-1 Shared libraries for terminal hand ii libreadline5 5.2-2 GNU readline and history libraries gdb recommends no packages. -- no debconf information -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
