I trying to learn Bitlash to make a websever, storing pages on a SD card. Currently I am working on bitlashsd at the moment to understand SD using bitlash. I'm getting the following errors:

bitlash\bitlash.cpp.o: In function `scriptfileexists':
C:\arduino-1.0.1\libraries\bitlash\/src/bitlash-instream.c:50: multiple definition of `scriptfileexists(char*)'

bitlashsd.cpp.o: In function `sdappend()':
bitlashsd.cpp:(.text._Z8sdappendv+0x40): undefined reference to `sdwrite(char*, char*, unsigned char)'

I'm using the SDFat library referred in the documentation and the Sd card on an ethernet shield with a Mega 2560.

Hello:

I wonder if you did this little necessary surgery described at the top of the bitlashsd sketch:

Code:

- Edit bitlash/src/bitlash.h to turn on the SDFILE define: at or near line 340, make this:
//#define SDFILE
look like this:
#define SDFILE

- If you are using a Mega2560, edit SdFat/SdFatConfig.h @ line 85, make this change:
#define MEGA_SOFT_SPI 1

If you haven't already, try that and report back on whether your compile works better...

Best luck with your project!

PS: Update. OOPS: The define needs to be enabled, not disabled.  I've fixed fix the doc bug and have amended the text above.  For avoidance of doubt, please make line 340 look like:

Code:

#define SDFILE

The OOPS did the trick! Thanks!  Great Language, but for a old dummy like probably a steep learning curve.

The program runs and it will display the directory. I have a file called sdtest.txt on the sd, but type sd.test.txt or exists sdtest.txt both return a dashed line then missing arg.

Let's check the syntax.  Bear in mind that the SD card functions are proper functions that require parentheses for their arguments:

Code:

> dir()
> dir        // you can omit the parens if there are no args
> type("sdtest.txt")
> exists("sdtest.txt")

Does that help?
