I downloaded FORTRAN Composer XE 2013 Update 1 for OS X* to put on my Macbook Air. After starting the installation, a message popped up saying that startup script could not run - error while executing the startup script. Also, a message said that I needed to grant write permissions to /tmp folder and Users/Shared/Library/Application/Support/Intel/Licenses folder. What is all this?

suppress floating invalid in runtime check due to large number
Dear Sirs,
I have ifort (IFORT) 12.1.3 20120212 on the Linux Debian server, and I would to suppress error message with runtime-checking flags.
The short F90 testing program is attached.
First, I got the code code execution proper :
:~/work/programming/various/floating_invalid/.ifort -i8 -g -O0 test.F90 test.F90(8): remark #7960: The floating overflow condition was detected while evaluating this operation; the result is an Infinity. [1.7976931348623157E+308]
Which OS and newbie questions.
Hello everybody,
I am interested in numerical problems and am trying the evaluate version of the Intel Fortran compiler.
I have been an old Fortran 77 user and I would like to switch back to fortran, since now it also adheres to most of the modern programming paradigms.
I am running the evaluate version of the Intel® Fortran Composer XE 2013 for OS X*, on my MacBookPro6,2; i5 2.4 GHz with 4GB RAM. I have tried the famous 'hello world' on XCode using a .f90 extension and it compiled and had been executed successfully.
Execution error
After i installed Fortran Compiller for Linux XW 2011 and tried to compile a sample code a see this message:
:/opt/intel/composer_xe_2013.0.079/Samples/en_US/Fortran/vec_samples$ ifort matvec.f90
ifort: error while loading shared libraries: libintelremotemon.so: cannot open shared object file: No such file or directory
Looking for a solution, i unistalled the software and re installed in an other PC, with the next results

polym. array of polym. elements having array-valued type-bound func.
Hello,
with a program similair to the following example I ran into a very confusing problem:
A polymorphic array of pointers (containers with a reference "ptr" pointing to a polymorphic "obj"-type) is allocated and initialized. Then, calling a type-bound array valued function from any referenced "obj" in that array behind the first causes a segmentation fault, unless the array elements are accessed in a loop with index starting by 1.
More details are given below the code.
