[photran] Problem Implementing Eclipse 2019-06 with Fortran
|
I am a new user for Eclipse, although I have been using computers since
the early 1960's for my work.
I downloaded the 2019-06 version for my Debian Linux platform and
elected to install the Eclipse for Scientific Computing as my first
programming language was FORTRAN II (yes, there was that version.) I
then downloaded and installed PyDEV as I am also using Python for some
of my applications. But enough background.
Implementing Python presented no problems. FORTRAN, however, is another
matter.
I have been trying to follow the steps in the 'Starting a Project with
an Auto-Generated Makefile" in Help.
Step 3. Choose "Executable (Gun Fortran)' from the project type list.
The problem is that there is no such selection in Executable pull down
menu. Unchecking the "Show project type . . ." dones not expand the list.
There is an entry "Executable (Gnu Fortran on Linux/*nix)" in the Others
pull down menu.
At this point, about ready to give up, but on a whim, i opened a
terminal and ran 'gfortran hello.f90' which resulted in an executable
a.out file, which, when run output 'Hello World. But, when I clicked on
Build Targets/HelloFortran/Debug/hello I got the followign errors:
14:53:00 **** Build of configuration Debug for project HelloFortran ****
make hello
cc hello.o -o hello
/usr/bin/ld: hello.o: in function `MAIN__':
/home/comp/Apps/Eclipse/workspace/HelloFortran/Debug/../hello.f90:3:

/usr/bin/ld:

/usr/bin/ld:

/usr/bin/ld: hello.o: in function `main':

/usr/bin/ld:

undefined reference to `_gfortran_set_options'
collect2: error: ld returned 1 exit status
make: *** [<builtin>: hello] Error 1
"make hello" terminated with exit code 2. Build might be incomplete.
14:53:01 Build Failed. 8 errors, 0 warnings. (took 300ms)
At this point an excess of mental entropy made me decide to take an
break and compose this message.
Is there a better source of help than the Eclipse Help Files?
I appreciate the effort expended to read to this point.
Thanks in advance.
