Up to now Xcode is not a great tool to develop Fortan codes.
The best compiler integrated to Xcode is iFort by Intel. The lattest version can be easily integrated in Xcode (A documentation provided by Intel explains how to do it). This permits to develop thanks to Xcode editor and to compile.
Unfortunatly,
- Fortran syntax is still not fully recognized. (For example there is no way to recognize DO loops or IF tests and collapse them as for other langages with Xcode as C, java, ...)
- idb, the Intel debugguer is still not compatible by Xcode and Xcode cannot be used to debug Fortran code. Intel is working on the subject.

As far as I am concerned :
- I am using Xcode to develop fortran code because of the nice interface to manipulate complex codes
- I am compiling in command line
- I debug with other tools.

I am happy to learn that it is possible to debug fortran code thanks to Xcode. I never succeeded to make this work on my code. Do you succeed to access global variables ? If yes which compiler / debugger do you use ?

By the way do you succeed to use Instruments and Shark (with source code) on it ?

Hi Dave,

I am trying to run and debug Fortran programs on Xcode, what should I do??, I am using gcc/gfortran because I can't find a free icc/ifort compilers for Mac...

Is there any guide or something??

Thank you.

I second (third, ..) that. Any suggestions on how to debug (or even study performance issues) from within xcode with the intel fortran compilers would be greatly appreciated! I can edit, build etc a fairly complicated code within XCode using a makefile as external target. But I cannot find useful information on how to use breakpoints etc.

Hey everyone !

I stuck in the same position : unable to compile any fortan in Xcode (even from C).
I have followed many posts about FortanPlugIn (XCode 2.4, 3.0, 3.1 ...) in this forum
I have been trying for days to compile very simple code in fortran from C ...

My config :
XCode3.2.3
gfortran-42-5664.pkg from http://r.research.att.com/tools/
libgfortran-4.2.4-5646 (dynamic lib) from http://r.research.att.com/tools/
latest "FortranPlugin.pbplugin" in /Developer/Library/Xcode/Plug-ins
latest "Fortran File.pbfiletemplate" in /Developer/Library/Xcode/File\ Templates/Fortran

What I have tried :

main.c

#include

int main (int argc, const char * argv[]) {
// insert code here...
printf("Hello, World from MAIN.C!\n");
test_();
return 0;
}

Fortran.f95

subroutine test
print *,"Hello World from FORTRAN!"
end

XCode error:
"_test_", referenced from:
_main in main.o
ld: symbol(s) not found
collect2: ld returned 1 exit status
I have the same error when I try to add "-lgfortran -lgfortranbegin" in "Other Test Flag" and "/usr/local/lib/" in "Library Search Fields" in my target file information ...

Terminal error :
MacBook-Pro-de-Mac-PNT:Fortran macpnt$ gcc -c main.c
MacBook-Pro-de-Mac-PNT:Fortran macpnt$ gfortran -c Fortran.f95
MacBook-Pro-de-Mac-PNT:Fortran macpnt$ gcc -o test Fortran.o main.o -lgcc_s.1

I don't see what I am doing wrong ... has anyone found a working HowTo to compile fortran from C ? or can anyone help me to debug this ?

Or Can you share your working configuration (XCode, fortran compiler ...) ?

Thanks !
