Dear Stephen P. Molnar

You had to create the project using the entry Executable from the other pull
down menu.

You can connect me directly via: yehuda.singer@xxxxxxxxx

Subject: [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:

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.
