Hi,
I want to use TinyECC in Eclipse.
Where do I have to include the TinyECC-Folder that I can use it correctly?
I included it in the run configurations, in the global tinyOS-Settings
and in the project preferences.
the plugin finds the files from ECC, but it throws me errors in ECC.h
which i included in the first row.
the error is:
(in included file; see ECC.h: 72) data object declaration: expected a
'field declarations', common
missing tokens at this place: '}', to complete expression, insert one
of: '}', 'typedef', 'extern', 'static',
'auto', 'register', 'void', 'char', 'short', 'int', 'long', 'float',
'double', 'signed', 'unsigned', '_BOOL',
'_Complex', 'struct', 'union', 'enum', 'const', 'restrict',
'volatile', 'inline', 'default', 'nx_struct',
'nx_union', 'command', 'event', 'async', 'norace', 'task', 'typedef name'
This error is dislpayed for other rows in ECC.h, too.
When I open ECC.h, there is no error showen.
I attached the ECC.h and the in ECC.h included NN.h
Thanks for your help!
Markus
