unresolved symbol exosite_write

Markel Robregado

Hi,

I can't seem to figure out what is causing this error below.

unresolved symbol exosite_write, first referenced in ./cloud_demo.obj

cloud_demo() is called at my main c file. The exosite_write() function is declared at C:\EK-TM4C129\exosite\exosite.h. I set at Include Options "${TIVAWARE_ROOT}/exosite". Where TIVAWARE_ROOT = C:\EK-TM4C129.

Any ideas why I am getting this error?

#include "exosite.h"
#include "exosite_pal.h"

/*****************************************************************************
*
* cloud_demo
*
* \param None
*
* \return None
*
* \brief The Exosite Cloud main application
*
*****************************************************************************/
void cloud_demo( void )
{
exosite_write("windspeed=55",12);
}

For whatever reason after doing this activity below, the build error went away.

1. Made a new folder at project workspace and linking exosite folder to it. I followed the guide from this link. processors.wiki.ti.com/.../Linking_folders_to_a_project
2. Got errors after build.
3. Did some very minor corrections to exosite.c
3. Returned back to original CCS project configuration which I got "unresolved symbol exosite write".
4. After build the "unresolved symbol exosite write" error went away.

I take back what I said that the build error went away. A little bit sleepy when I replied that. The build error went away because, I commented out the cloud_demo() call from my main c file. The unresolved symbol error still remain.

At File Search Path this is set below. That is the location of exosite.c and exosite.h. At file exosite.c is where the exosite_write() is defined. But, I still get the unresolved symbol exosite_write error.

"${TIVAWARE_ROOT}/exosite"

Hi Ki,

I was able to solve the error by adding exosite.c and exosite.h files to my CCS Project Workspace with the option "Link to Files.

But, how do I solve the error by just setting at CCS Project Properties? At qs_iot example program for Tiva Connected Launchpad the exosite folder that comes with Tivaware is linked to the qs_iot CCS Project by this include search path below.

"${SW_ROOT}/third_party/exosite"

My exosite folder files is different from that one. This folder location is set at

${TIVAWARE_ROOT}/exosite, where TIVAWARE_ROOT = C:\EK-TM4C129

If I do this way I get the unresolved symbol error. But, it is just same way Tivaware qs_iot example program which builds without errors.

Nevermind, my last question. I understand now that I need to make a folder at my CCS project and then link the exosite folder to that.
