Compile Errors with webclient example on Raspberry / Alamode

[psegov]

Hello I am getting compile errors when try and run the examples on Raspberry PI / Alamode. I have searched around for a solution, but still have not found a fix that works so I thought I would post here to see if others have run into this issue. I am using RN-XU wifly rev. 3 on a seeedstudio bees shield.

The sample I am compiling is (no changes):
/home/pi/WiFlyHQ-master/examples/httpclient

Here are the errors:

Any help would be greatly appreciated.

I found the solution to this issue, prog_char has been depreciated in newer versions of avr-lib. I have updated the example and library I would like to contribute this back to the community.

[dlefur]

Hello,
how did you fix it ? Is there a new version of this WiflyHQ files ?

Thanks.

[harlequin-tech]

Looks like it will need a re-write to use the __flash keyword for variables accessing progmem, which would be compatible with 4.7 avr compiler. That would break compatibility with the older compiler, so it needs a solution to support both.

[t-liebscher]

@dlefur - to fix it replace all occurrences of the "prog_char" with "char PROGMEM" in the library and example files. I also commented out the two lines:
#undef PROGMEM
#define PROGMEM attribute(( section(".progmem.data") ))

and all works perfect

Hello,

I have updated the wiFlyHQ library on the alamode / raspberry pi setup. I wanted to let you know that there are still compiler errors.

Thanks for the continued work on the library. I will updating the local version of the library.

Hi,

this should have been handle by the following line in WiFlyHQ.h:

#if (ARDUINO >= 103)
typedef const char PROGMEM prog_char;
#endif

Actually, if you are building for an ARM target then you would need to add a line to do the same for the ARM I think.

That is what I thought too.. Was really excited to see the updates.. I am using raspiberry pi as my development platform which is arm based.
