photran

Hi,
I'm not sure if this is Photran-specific or it's addressed elsewhere in 
the Eclipse docs, but I'm having trouble understanding if/how to share 
code among several projects without building libraries or duplicating 
source code.
Simple example: In ~/workspace/cow I have a source directory (src) 
containing cow.f90 (the PROGRAM) and two modules m_graze and m_moo in 
m_graze.f90 and m_moo.f90, respectively. This builds and links properly 
to create the executable 'cow'. The executable and modules (m_graze.mod 
and m_moo.mod) are stored in ~/workspace/cow/Debug and object files are 
stored under ~/workspace/cow/Debug/src
Later, I create ~/workplace/sheep and have src/sheep.f90 as the program 
and src/m_baa.f90 as the module m_baa. I want to 'use m_graze, only: 
ruminate' in sheep.f90 to get access to the ruminate() subroutine.
If I try to compile the sheep project, I'll get an error like:
error #7002: Error in opening the compiled module file.  Check INCLUDE 
paths.   [M_GRAZE]
Under Properties:Project References for sheep, I can select the cow 
project. Under Properties:Fortran Build:Settings:Intel 
Compiler:Preprocessor I can add ~/workspace/cow/Debug (location of the 
module files) so the compiler now finds the cow modules and compiles 
sheep.f90. However the linker dies with something like
Building target: sheep

Invoking: Intel(R) Fortran Linker

ifort -L/home/me/workspace/cow/Debug -o "sheep"  ./src/sheep.o

./src/sheep.o: In function `sheep':

/home/me/workspace/sheep/src/sheep.f90:11: undefined reference to 
`m_graze_mp_ruminate_'
This would normally be solved by adding libraries and library paths to 
the linker settings except that there are no appropriate libraries to 
link to (this is Fortran, not C.)
The cow project was perfectly capable of compiling and linking together 
cow.f90, m_graze.f90 and m_moo.f90 into an executable. Yet while the 
sheep project can compile sheep.f90 and m_baa.f90 and can find the 
module m_graze.mod, it can't seem to find the symbols for m_graze even 
though all the requisite information is present on the system for it to 
do so.
It would seem to be an easy matter of configuration to get the linker 
portion of ifort to find the missing pieces and put them together but I 
have no idea what magic words need to be entered where in the Photran UI 
to make this happen.
I confess an utter lack of interest and competence in C and the C build 
process and I'd rather avoid the diversion of creating libraries (.a or 
.so) unless that's the only way to make this work.
Ultimately, I'm looking for a pure Fortran solution to this problem so I 
can keep a single copy of the source code and don't have to manually 
maintain a pile of custom Makefiles.
So can this be done?
Apologies if this has already been documented somewhere; Google is only 
showing me simple build examples, how to create modules, and how to link 
with existing libraries. There don't seem to be (m)any examples of code 
reuse with modules.
Thanks for any light you can shed on this,

An update would be nice. There are a few new options that would be nice 
to have in the Settings page (F2003 standards check, for example) and 
it'd be lovely if the Windows version of the Intel toolchain could be 
supported. I'd help code it but I couldn't make heads or tails of the 
Java code the last time I looked at it. :/

Hi Brian,
I help manage a weather forecasting software package called WRF

Good to hear from you!  WRF is in Photran's (internal) test suite, but 
mostly as a goal...
It looked, at first glance, like all refactoring operations are 
disabled for Fortran source with C preprocessor directives.

1.   Are there any workarounds for refactoring Fortran code with CPP 
directives?

Unfortunately, not really, not at the moment.
Refactoring in the presence of preprocessor directives is still a 
research topic.  My group at Auburn University is working on fully 
preprocessor-aware refactorings for C.  We hope to migrate our work to 
handle C-preprocessed Fortran (in Photran) in the next year or two, but 
it will depend on funding, etc.  Completely handling WRF would be 
fantastic.  (On that note, if you know someone at UCAR or elsewhere who 
would be interested in working with us to fund that kind of work, I'd 
really like to talk to them...)
2.  Can other features of Eclipse/PTP help us with finding and fixing 
certain "bad" code blocks that appear?

This is a really good idea... and also one that Photran doesn't 
implement at the moment.

Managing this complex software with an IDE would be extremely helpful, but the IDE support for complex Fortran (i.e. free-form, with script-generated code inserted with CPP directives) has traditionally been absent.

It looked, at first glance, like all refactoring operations are disabled for Fortran source with C preprocessor directives.   Since most of the WRF software has these directives, which inserts automatically generated Fortran code sometimes in excess of 10,000 lines, it would seem l am still out of luck as far as using Eclipse/Photran to manage and try to control its ever-growing gnarliness.

One example: we don't want users writing debug messages  directly to various output streams, but call one of our debug message handling functions instead.   We would like Fortran lines of the form

I can't answer to your question about CCP directives.

About mange complex code, I'm developing fortran code not large as your code but it is about 100000 lines.
The use of Eclipse/Photran works very well and I'm really appreciate it, although, I've encountered several problems relatively to the size of the code/files :
- I don't find convenient to work with large files (more than several thousand lines), but it is OK.
- Unfortunately, I can't use refactoring (I've to disable it). I've had several "internal error" and I've had to "rebuilt the database" often. The worst is to save a file which can take ages (sometimes several minutes).

Every new version of Eclipse/Photran, I'm trying "the refactoring feature", but I don't see improvement.

Best regards

David

Hi all,

my colleague recently installed Eclipse Juno with the latest version of 
Photran. Everything works beautifully except that he gets strange syntax 
error messages in the project tree view. The problem is well visible on 
the screen shot available here: 
http://superflip.fzu.cz/download/photran_problem.jpg.

The project is a rather large, but otherwise standard Fortran Makefile 
project. File extensions are f95, but the code is in fixed format. We 
have changed the file settings to fixed format for f95 extension 
wherever we could find it, and the project recognizes the files as fixed 
format. Nevertheless the parser identifies strange syntax errors. The 
syntax error displayed on the screen shot points to a line with nothing 
but comments in it. This or similar syntax errors appear in essentially 
all files of the project.
I would greatly appreciate any hint about what might be causing this 
behaviour or what diagnostics should we perform to identify the source 
of the problem.
With best regards
Lukas Palatinus
