Hi.I am writing a program and when i want to compile it there are
a lot of error like this: 
.\camera.axf: Error: L6218E: Undefined symbol ov7670_set (referred
from main.o).

Include files do not provide code, they provide interfacing
details for the compiler. The code for the functions still needs to
be provided in the source files of your project or libraries you are
linking in.&lt;/p&gt;

&lt;p&gt;
These are some pretty basic C programming concepts. Can you
perhaps review so books/manuals related to compilers, assemblers and
linkers, and the use of multiple source files in a project.&lt;/p&gt;

Sorry i did not understand what you mean.if you talk more specific
i will be appreciate.&lt;br /&gt;
i wrote headers for my program in a file.h and i used them in a
file.c after that i wrote main of program and used these
functions.&lt;br /&gt;
what else should i do?&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: error</title><link>https://community.arm.com/thread/64830?ContentTypeID=1</link><pubDate>Sat, 02 Jul 2016 07:19:19 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:33e4891f-0c90-4a09-b952-b3ea0e2a22d9</guid><dc:creator>Westonsupermare Pier</dc:creator><description>&lt;p&gt;&lt;p&gt;
Linker says you are using functions where you have no code within
your project providing that functionality. Add those functions, the
linker will be happy again.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
