Several Questions.

Several Questions.

[Stephen P. Molnar]

Question 1.  How do I join the gfortran users mailing list?

Question 2 (a tad longer than 1):

I have the source code for a fortran program that I wrote in 1996 using 
the Microsoft FORTRAN compiler that I would like to port to gfortran as 
I no linger have a copy of the Microsoft application.

I have Debian v-9.1.0 installed on my 64bit AMD platform with the 
distribution with gcc/gfortran installed.

Much to my surprise, gfortran produced an executable file with only 
correcting a couple of typographic errors.

Naturally, there were run errors:

comp@AbNormal:~/Apps/gFortran$ ./mt3dm1 B1.prn
At line 18 of file MT3DM1.FOR (unit = 1)
Fortran runtime error: Cannot open file '': No such file or directory

Error termination. Backtrace:
#0  0x7f3b14086d4a
#1  0x7f3b14087825
#2  0x7f3b14087f79
#3  0x7f3b141478fa
#4  0x7f3b14147b3d
#5  0x4023e3
#6  0x40300c
#7  0x7f3b1358b2b0
#8  0x400a19
#9  0xffffffffffffffff

Which I assumed that the source code was not linked to the necessary 
libraries.

So I tried winking with the -static switch. Again (not surprisingly) errors:

comp@AbNormal:~/Apps/gFortran$ gfortran -static -fno-align-commons 
MT3DM1.FOR -o MT3DM1s
/home/comp/Apps/psi4/lib/gcc/x86_64-unknown-linux-gnu/5.2.0/../../../libgfortran.a(main.o): 
In function `_gfortrani_find_addr2line':
(.text._gfortrani_find_addr2line+0xe): undefined reference to 
`__secure_getenv'
/home/comp/Apps/psi4/lib/gcc/x86_64-unknown-linux-gnu/5.2.0/../../../libgfortran.a(unix.o): 
In function `_gfortrani_open_external':
(.text._gfortrani_open_external+0x86): undefined reference to 
`__secure_getenv'
collect2: error: ld returned 1 exit status

Question 2 then is what's missing?

I am sure that there will be a necessary editing of in and out 
statements, but those can wait.

Thanks in advance for yer  attention.

Hi Stephen,

This, in fact, is a list for the developers of gfortran not users.

However, your problem does deserve some attention. Janne Blomqvist
picked it up earlier on this year:
https://gcc.gnu.org/ml/gcc-patches/2017-04/msg01388.html

Given the content of the thread, I rather think that you should not
use static but instead set LD_LIBRARY_PATH to include libgfortran. In
my linux distro /lib64 has the system supplied libgfortran.

Regards

Paul

Select Fortran from the list and follow instructions.

Need to see source code, but it looks like you tried
to open unit with an empty file, i.e.,

   open(unit=1,file='')

1. Unit 1 is normally standard input, so you're closing stdin.
   Folklore suggests starting unit numbering at 10 and go up.
2. gfortran can't find a file in the current working directory
   named ''.  So, gfortran issues a runtime error.

Your system does not have libunwind or gfortran cannot find libunwind,
so the stack trace is simply addresses.  If you do not have libunwind,
you can prevent the noise by adding -fno-backtrace to your command line.

Cannot help you here as I do not use Linux (or Windows).

Thanks for the answers.

I wasn't sure if I was using the correct address.

I will probably post the code as soon as I have made as many edits as I can.

You can also set the environment variable

export GFORTRAN_ERROR_BACKTRACE=N

If you find the backtrace bothersome.

If you want to subscribe to the list, go to https://gcc.gnu.org/lists.html#subscribe and select fortran.

As usual, you need to post the code in order to get some help.

Welcome on board!
