Array Size Limit

[ElectronDes 0]

When using boostc_pic18 (v6.97) inside MPLAB IDE (v8.53.00.00) and trying to declare an array of more than 256 elements, the message "error: total number of array elements can not exceed 0x100 (use -idx 2 compiler command line argument to remove this restriction)" is displayed.

 

Trying again with -idx 2 set as an option thus:

boostc_pic18.exe Filename.c -O1 -W1 -t 18F8722 -idx 2

gives:

 

warning: unrecognized command line agrument '-idx', skipped

 

FileName.c

C:\Pathname\Filename.c(138): error: total number of array elements can not exceed 0x100 (use -idx 2 compiler command line argument to remove this restriction)

2

FATAL: Unable to open input file: C:\Pathname\2

Error: preprocessing error

 

similarly, trying -idx2 thus:

boostc_pic18.exe Filename.c -O1 -W1 -t 18F8722 -idx2

gives a similar result:

warning: unrecognized command line agrument '-idx2', skipped[\b]

 

Trying again with -IDX 2 set as an option thus:

boostc_pic18.exe Filename.c -O1 -W1 -t 18F8722 -IDX 2

gives (note NO warning about skipped command line agrument):

 

FileName.c

C:\Pathname\Filename.c(138): error: total number of array elements can not exceed 0x100 (use -idx 2 compiler command line argument to remove this restriction)

2

FATAL: Unable to open input file: C:\Pathname\2

Error: preprocessing error

 

and again trying -IDX2 thus:

boostc_pic18.exe Filename.c -O1 -W1 -t 18F8722 -IDX2

gives a similar result.

 

Can someone tell me how to get around tis problem please?

Can someone tell me how to get around tis problem please?

Wait for BoostC V7, this has support for large arrays. A release candidate should be coming soon.
