- Fortran print allocatable array in gdb 3 answers
I've debugged the following piece of code in Cygwin and Eclipse using gdb as the debugger:
program codetest
implicit none
integer, parameter :: dp = kind(1.0d0)
integer, parameter :: N = 10
real(dp), dimension(:), allocatable :: vector
integer :: i
allocate(vector(1:N))
forall(i = 1:10)
vector(i) = sqrt(real(i, dp))
end forall
write(*, '(F7.3, 1X)', advance = 'no') (vector(i), i = 1, N)
deallocate(vector)
end program codetest
When running gdb, I attempt to print the allocatable array "vector" following its allocation, but I end up with the following:
(gdb) p vector
Unhandled dwarf expression opcode 0x97
I've scoured Stack Overflow and Google, but I haven't found anything that gets to the heart of the matter. I've checked out the following,
- http://numericalnoob.blogspot.be/2012/08/fortran-allocatable-arrays-and-pointers.html
- Unhandled dwarf expression
- Fortran print allocatable array in gdb
but I'm still not understanding what the problem is or how to fix it. I've gotten the same complaint from gdb in Eclipse (Mars.1 Release, 4.5.1) when trying to print/display the contents of a derived type. Current specs about my machine/compiler/debugger include the following:
- Windows 8.1
- gfortran version: GNU Fortran (GCC) 4.9.3
- gdb version: GNU gdb (GDB) 7.8
Any help is appreciated.
