Error due to multiple causes

The error message is caused by one of three following causes:

— The Simulink model is unable to locate variables which it needs to run correctly inside of PARFOR.

To debug this issue place the SIM command calling the Simulink model inside of a TRY CATCH block as demonstrated below, and attempt to execute the model again. By placing the SIM command inside of the TRY CATCH block you will be able to identify all the variables that the model expects in the global workspace, and which are not present on the workers when the model is called.

The contents of error_var, stack_var, exception_var will be useful in determining the missing variables.

Please be aware that Simulink requires are input variables to be present in the ‘base’ workspace. To ensure that the missing variables are placed inside of the worker ‘base’ workspace use the ASSIGNIN command:

Also the model always returns output variables either to the global workspace or as the output of the SIM command. If you don’t specify the output variable for the SIM command and the model outputs variables which you need to return back to the calling program or to the client, or the model is called from within a function, you will need to use the EVALIN function to copy these variables to the local function workspace as follows:

— The Simulink model is run in accelerated mode and tries to compile itself across multiple instances at the same time causing file corruption.

For information on how to resolve model compilation issues please review the following section of documentation by typing the following in the MATLAB Command Window:

You may access the same information on the following webpage:

— You can also debug the Simulink model by placing it inside of an SPMD statement, or submitting it as a parallel job. When you submit the simulation as the parallel job, the errors will be included in the Parallel Task Error and ErrorMessage properties.

More information about ErrorMessage property of the Task object is available by typing the following in the MATLAB Command Window:

You may access the same information on the following webpage:

Note that when debugging a model using parallel jobs, there might be File and Path Dependencies that might have to me satisfied before the model starts executing correctly. More information about Path and File Dependencies is available by typing the following in the MATLAB Command Window:

Есть ли у кого опыт успешной установки под линукс?

Пробовал матлабы 2010б, 2010а, 2009б не получается, лог ниже

>>setupDSPBuilderPath ('install', false, '/usr/altera/10.1sp1/quartus/dsp_builder/bin', '/usr/altera/10.1sp1/quartus/dsp_builder/bin/matlab', '/usr/altera/10.1sp1/quartus/dsp_builder/bin/mdllibrary')

Install type is install
Creating board components
Error executing : createSBlock('ComponentFactory', 'Stratix_EP1S25_alteradspbuilder2', 'Stratix_EP1S25:config', 'Stratix EP1S25 DSP Development Board');
Previous command was : alt_dspbuilder_internal_new_system('Stratix_EP1S25_alteradspbuilder2', 'Library');

Information on the last error:

Message: Error using ==> createSBlock at 46
Error due to multiple causes.

Failed at

тоже самое и для 10.1 версии.

детали того, что есть и прочее

1) матлаб устанавливался 32 битный

2) пробовал добавлять пути в ручную в classpath.txt, тогда при попытки открыть пример из дспбилдера получаю такое

Error in block : Test3C120Board_QuadDisplay/VCC
Error due to multiple causes.
....

2.1) Отрывал пример и пытался менять свойства какого либо модуля получал такое «invalid MEX-file»

3) пробовал из под рута с тем же результатом

У меня есть подпрограмма С++, которую я хотел бы упаковать в Simulink S-Function. Эта подпрограмма С++ вызывает другие подпрограммы, которые находятся в нескольких других файлах на С++.

Мне удалось собрать все скомпилированные файлы (т.е. файл mexglx), используя инструмент legacy_code. Однако выдается следующее предупреждение:

Warning: You are using gcc version "4.4.4-14ubuntu5)".  The earliest gcc version
supported  with mex is "4.1".  The latest version tested for use with mex 
is "4.2". To download a different version of gcc, visit http://gcc.gnu.org 

Проблема возникает, когда я пытаюсь сгенерировать блок S-Function, выписав команду:

legacy_code('slblock_generate', def);

В этот момент возникает следующая ошибка с упоминанием версии GLIBCXX:

Честно говоря, я немного потерял в этот момент. Я не знаю, было бы достаточно понизить компилятор g++, или если мне придется делать некоторые другие вещи. У вас есть возможное решение этой проблемы?
