g95 back on stage

[Arjan]

I always liked the feedback of the g95 compiler. The resulting executables were slow, but many, many more bugs were eliminated (compared to other compilers) thanks to g95's unforgiving comments about my code! Today, I saw that Andy seems to have blown new life into g95 development! Hurray!!

Yes, some bug fixes appear on the web site. There are new builds but not yet for Linux x86-64 or Windows.

Hurray!!

Good to hear. I hadn't heard from him in a long time. I also like(d)
several things about g95. Its one big potential problem in my mind was
that it was so dependent on a single person.

Encore!!
I had given up on G95. I think the problem is that Andy could use some
help. Does he want it though?

Yes, there are quite a few minor upgrades to g95 which would make it
much more useful. For example: I've started writing code using things
like OPEN(NEWUNIT=u, ...) to save the trouble of having to find an
unused unit number, which is supported by gfortran and many commercial
compilers, but isn't in g95 at present.

Great! Since I roam on the savannah I tend to use gfortran these days,
but as I recall, you seemed to prefer g95. What we need is choice.

Hacking solo can take a lot out of you. Andy, besides being smart, is
very brave. I'm just glad he found the beans to get back into the game
and I hope he gets more support this time. Paying the rent and hacking
free software can be difficult.:)

Happy Holidays everyone!!

What really amazes me that the install executable is just 5MB. Such simplicity, you can solve very complex problems, by concentrating on the problem and not fancy bells and whistles. Think that the new Intel FORTRAN install approaches 900MB, the gFortran is around 65MB, and here is g95 just 5MB.. Andy must be a genius

[Ron Shepard]

In article <7c0c28d3-efbf-4c53...@googlegroups.com>,

In the case of Intel, I think that includes all of the parallel
support along with the MKL library, which used to be a separate
product, and very extensive documentation. It is not just the
parser and code generator of the compiler.

However, more compiler choices are better than fewer.

I'm sure he is, but as Ron and Clive point out the additional MBs bring
additional functionality.

Members of this group seem to like particular features of G95. What Andy
needs to do is keep the compiler lean and mean. We could help him keep
G95 distinctive by suggesting features for inclusion, and letting him
know what we find really useful.

I tried downloading g95 and got it to compile a simple console
program, but failed with a Windows program (-mwindows and WinMain).
After compensating for the lack of IANY and C_SIZEOF and working
around a bug with accessibility and a couple of ICEs with TRANSFER
and the lack of COMPILER_VERSION() and STDCALL name mangling, I
couldn't seem to get over:

c:/g95/bin/../lib/gcc-lib/i686-pc-mingw32/4.1.2//libf95.a(main.o):(.text+0x32):
undefined reference to `_MAIN_'

Has anyone gotten a Windows program to function in g95? Maybe
I did once but forgot how...

I have used g95 in the past on 32 bit linux and found it usefull. I now
use Linux x86-64. The absence of a build for Linux x86-64 is therefore a
problem for me, so I tried to build one from the source files. As
suggested at:-

http://www.g95.org/source.shtml

I downloaded gcc-4.0.3, even though I have 4.6, and tried to build that
gcc. That version is very old. The files are dated 2006. That web page
says:-

"Run 'make' to build gcc. A full build isn't necessary. If you end up
with libbackend.a, and libgcc.a, you've got enough to build g95. If
libgcc.a isn't present, try 'make libgcc.a'.".

It made libbackend.a, but not libgcc.a and 'make libgcc.a' reported "no
rule for making libgcc.a. I am therefore stuck and have no ideas. Does
anyone have any ideas?

Before trying that I earlier emailed Andy about the Linux x86-64
binaries, but he has not yet replied.

Cheers, Brian.
