enet_io example not compiling on DK-TM4C129X kit

Hello Badvani,

I just did the same process of importing the enet_io and it compiled without any errors for me in CCSv5

Looking at the error, it seems some files are missing. Can you check the missing symbols in the directory

C:\ti\TivaWare_C_Series-2.1.0.12573\examples\boards\dk-tm4c129x\drivers

and whether it is getting compiled in the compilation logs?

Regards

Amit

Perhaps the, "blow by blow" listing of that, "process" will benefit from your currency & skill set.  (i.e. issue has been noted - multiple times past - that "process" may be in need of a rethink and/or further detailing...) 

Poster's point re: "expecting it to work, "out of the box" seems fair & reasonable."

Hello All

The import and subsequent compilation of the enet_io worked. If we can get the CCS project in a zip we can check what is that is not working.

Hi Amit,

The project zip file is attached: 3632.enet_io.zip

I do not know what you mean by checking the symbols in the drivers directory. Here are the contents of my tivaware/examples/boards/dk-tm4c129x/drivers folder:

Sorry for being very ignorant regarding the issues at hand here. Thanks.

Just an update - I replaced the links in enet_io/drivers with the actual files, and that resulted in a successful compilation. With that being said, the links that were previously in enet_io/drivers did resolve to the correct locations of the files. I do not know why my change fixed the issue I was having.

Hello Badvani

Could it be possible that the installation of the TIVAWare and Example codes were done differently?

Good to hear that you resolved it through the links.

Regards

Amit

[The original poster looks to be using CCS under Linux]

With TivaWare 2.1.0.12573 I was able to import and compile the enet_io example for the EK-TM4C1294XL using CCSv6 for Linux.

However, when the enet_lwip example is imported into CCSv6 under Linux the example failed to compile with the linker reported unresolved symbols. Whereas the enet_lwip example did import and compile without error with CCSv6 under Windows.

6740.linux_enet_lwip.zip is the enet_lwip example imported with CCSv6 under Linux which failed with unresolved symbols

1680.windows_enet_lwip.zip is the enet_lwip example imported with CCSv6 under Windows which compiled without error.

It looks like the enet_lwip example which was imported under Linux has the drivers, third_party and utils directories missing.

In the .project file from the example imported under Windows, the following section was manually copied into the .project file in Linux:

The enet_lwip example then successfully compiled in CCSv6 under Linux.

Not sure if the problem is that the TivaWare example isn't compatible with Linux, of if there is problem with Linux version of CCSv6.

Hello Chester,

I have a windows installation for CCS and TIVAWare. The drivers, etc are part of the TIVAWare installation and would always be there. Also as you said the makefile was missing the relative links. Now that could be something that can be checked for.

Regards

Amit

Hi,

I had recently the same problem with Eclipse Kepler on OSX - the Eclipse cannot manage correctly relative paths for items installed as symbolic links, specially those related to Tiva installation folder. Also seems every time you change a path, Eclipse does not make the internal refresh for that path also. For me the cure was to set an absolute path instead a relative one in Compiler/include search path and to restart the Eclipse. After that, the compile/link process was OK.
