Oct 16, 2010, 11:45 am I have just been testing a 64kB SRAM module for my arduino mega I built based on the atmega 1280's external memory interface. However I seem to have hit some kind of software limitation in the arduino compiler.This works fine:Code: [Select]unsigned char a [30000];However this:Code: [Select]unsigned char a [60000];gives me "error: overflow in array dimension"Does anyone know what causes this? Or what the exact size limit may be?Thanks in advance.

I'm working with meshes and using Fortran to analyze entire of my mesh including nodes and elements. So, I have some variables, vectors and matrices. The biggest matrix has error overflow in around 61,000x61,000 arrays. During debugging of my program, following common message and highlighted ERROR are appearing every time: --------------------Configuration: Ali-0 - Win32 Debug--------------------Compiling Fortran...D:\\Thesis\\Fortran programming\\Copy of shin yokohama fortran\\Ali-0.forD:\\Thesis\\Fortran programming\\Copy of shin yokohama fortran\\Ali-0.for(25) : Error: A common block or variable may not exceed 2147483647 bytes & nfix(5000),r1(61000),sk(61000,61000)----------------------------------^Error executing df.exe. Ali-0.exe - 1 error(s), 0 warning(s) I know the reason is beacasue size of my matrix in bytes outnumbers maximum allocatable bytes for each matrix. I have no choice to use this matrix. I've searched the web for resons and solutions. It seems that this error relates to ram and operating system as well.I have 2 system 1- Window 32 bit 2GB ram, other Windows 64 bit, 6.00 GB. Could anybody help me resoling this problem! RSS Top 46 posts / 0 new Last post For more complete information about compiler optimizations, see our Optimization Noti
a detailed description of the error. To define the condition symbol values (PARAMETER statements) in your program, include the following file: for_iosdef.for As described in the table, the severity of the message determines which of the following occurs: with info and warning, program execution continues with error, the results may be incorrect with severe, program execution stops (unless a recovery method is specified) In the last case, to prevent program termination, you must include either an appropriate I/O error-handling specifier and recompile or, for certain errors, change the default action of a signal before you run the program again. In the following table, the first column lists error numbers returned to IOSTAT variables when an I/O error is detected. The first line of the second column provides the message as it is displayed (following forrtl:), including the severity level, message number, and the message text. The following lines of the second column contain the status condition symbol (such as FOR$IOS_INCRECTYP) and an explanation of the message. Number Severity Level, Number, and Message Text; Condition Symbol and Explanation 11 severe (1): Not a Fortran-specific error FOR$IOS_NOTFORSPE. An error in the user program or in the RTL was not an Intel Fortran-specific error and was not reportable through any other Intel Fortran run-time messages. 8 severe (8): Internal consistency check failure FOR$IOS_BUG_CHECK. Internal error. Please check that the program is correct. Recompile if an error existed in the program. If this error persists, submit a problem report. 9 severe (9): Permission to access file denied FOR$IOS_PERACCFIL. Check the permissions of the specified file and whether the network device is mapped and available. Make sure the correct file and device was being accessed. Change the protection, specific file, or process used before rerunning the program. 10 severe (10): Cannot overwrite existing file FOR$IOS_CANOVEEXI. Specified file xxx already exists when OPEN statement specified STATUS='NEW' (create new file) using I/O unit x. Make sure correct file name, directory path, unit, and so forth were specified in the source program. Decide whether to: Rename or remove the existing file before rerunning the program. Modify the source file to specify different file specification, I/O unit, or OPEN statement STATUS. 111 info (11): Unit not connected FOR$IOS_UNINOTCON. The specified unit was not open at the time of the attempted I/O operation. Check if co
