It finds the .lib file but I have a error : &quot;could not read symbols : File format not recognized&quot;.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/11914?ContentTypeID=1Mon, 28 Jul 2014 09:13:57 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8c295603-9c73-475d-bc79-b1a764d66879Vidar Berg<p>Have you tried using the full path and name to the lib file without the &#39;-l&#39; option?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/11913?ContentTypeID=1Mon, 28 Jul 2014 08:11:21 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f338aec5-3ac1-41f5-9d4d-1e843b2cb72fJUAN<p>This seems to work for .a files. I also have a .lib library. I have tried the same method. It is not linked. I know they are different in type of library. Do I have to convert the .lib to .a? Or is there another way to link it?</p> <p>Thanks in advance.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/11912?ContentTypeID=1Mon, 28 Jul 2014 06:44:42 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8d915f59-d78c-4e2f-97a3-aea05583695eVidar Berg<p>Hi,</p> <p>Just add &quot;LIBRARIES += -llibrary&quot; to your makefile. See <a href="https://gcc.gnu.org/onlinedocs/gcc/Link-Options.html">gcc.gnu.org/.../Link-Options.html</a> for more details.</p><div style="clear:both;"></div>
