This symbol has too many characters

Escarela-Perez__Rafa — Sat, 12 Apr 2008 02:40:37 GMT

Does anyone know how to solve the following error or its meaning?

My program used to be correctlycompiled by CVF.

ifort /c /warn:stderrors /stand:f03 /check:bounds /O2 /libs:qwin /nologo /I e:fldsml generic.f90
generic.f90(21) : Error: This symbol has too many characters. [T_IMAGE_RESOURCE_DIRECTORY_STRING]
CONTAINS

Thanks

You didn't use /stand:f03 with CVF, did you? Or any /stand at all?

C:Documents and SettingsSteve>df /c /stand t.f90

t.f90
t.f90(1) : Warning: This symbol has too many characters. [T_IMAGE_RESOURCE_DIRECTORY_STRING]

--------^

This is a standards violation diagnostic saying that the identifier has more characters than allowed by the standard. It would normally be a warning but you also said /warn:stderrors to force it to be an error.

The only problem here is that this diagnostic is inappropriate with /stand:f03 (it would be correct for CVF and /stand:f90 or f95). In F90/95, identifiers are limited to 31 characters, yours has 33. However, Fortran 2003 raises this limit to 63 characters and this seems to be a distinction we missed updating. I'll report it.

The easiest way out is to turn off /warn:stderrors or perhaps /stand:f03. You could also shorten the name by two characters.

Thanks for your helpful answers.You are right, I didn't use any /stand at all with CVF. However, I don't know how to shorten the name because the code of my fortran module does not contain this T_IMAGE_RESOURCE_DIRECTORY_STRING symbol. Is this symbol hidden in another way? I don't see problem in reducing it but I don't find a string within my code with more than 31 characters.

Thanks

Ah, I see. This symbol is defined in module IFWINTY. I assume that there is a USE statement somewhere that names one of the Win32 API modules. It is a bit surprising to me that a USE of a module with a long name would trigger the warning. I can't reproduce that. Can you post a small but complete source that shows the problem?

Or - hmm. Do you have an INCLUDE that defines Win32 API things?

One way around this is to use an ONLY clause on the USE to bring in only those names you are interested in. For example:

use kernel32, only: GetlastError, HANDLE, TRUE, FALSE

Or just drop the /stand for now.

Thanks Steve for your prompt answer. I am using IFWIN (Previously DFWIN) in a module which was compiled without /warn:stderrors. Iam ssuming that the error is reproduced later beausemy other module isusing this one. I have added an only clause as follows:
USE
IFWin, only: loadcursor, idc_cross

This too many characterserror has gone now. Thank you.

I have another problem with MKL. I am traying to test the mkl installation but I have linking problems. First, I am opening the Build Environment for applications running on IA-32 and set the mkl environment with mklvars32.bat.After this procedure, I want to complie and link the dss_sym_f90.f90 located in the E:Program FilesIntelMKL10.0.2.019examplessolversource with:

ifort dss_sym_f90.f90 mkl_c.lib libguide.lib

I get the following result:

-out:dss_sym_f90.exe

Could you help me?

Thanks again!!!!!!

I'm going to have to check out that module issue - that's weird.

I'd prefer you ask the MKL question over in the MKL forum, where the MKL experts hang out.

Thanks !!!!!. I found what mkl library must be used.
