UIA Linker Error

Brian Boru

Other Parts Discussed in Thread: SYSBIOS

Hi,

I've looked through all related posts and they have not addressed my issue. I am trying to include UIA in my build. I am using the BIOS PSP 03_00_01_00 build system, building from command line. I've installed uia_2_00_03_43, using bios_6_42_03_35 and have added the UIA path to my XDCPATH in my env.cmd file.

In my cfg file, I've simply added

var LoggingSetup = xdc.useModule('ti.uia.sysbios.LoggingSetup');

When I add this line, I get the following linker error in my build output:

In terms of my cfg file, here is the module related configuration:

Any ideas what could cause this?

Try adding this line to your config.

var LoggerStopMode = xdc.useModule('ti.uia.loggers.LoggerStopMode');

Hi Judah,

This gave me a different set of linker errors:

Thanks

Hi Judah,

Sorry, the linker error was the same as the original after adding:

var LoggerStopMode = xdc.useModule('ti.uia.loggers.LoggerStopMode');

I think my problem is that the UIA path is not being added properly. I'm building from command line, so I have a makefile which sets all environment variables, including my XDCPATH. In this makefile, I have:

# UIA
uia_PATH = $(EXTERNAL_SW_ROOT)/uia_2_00_06_52/
uia_INCLUDE = $(uia_PATH)/packages/

XDCPATH = $(bios_PATH)/packages;$(xdc_PATH)/packages;$(bios_psp_PATH);$(ipc_PATH)/packages;$(uia_PATH)/packages;
export XDCPATH

My build system doesn't seem to recognise the uia_PATH though. If I remove this from my XDCPATH, I still get the same linker error, so for some reason, XDCtools is not finding my UIA path and packages and I can't see why.

Correction.. my build setup (BIOS PSP command line) does recognise this UIA path; it will build if I add this:

var LoggingSetup = xdc.useModule('ti.uia.examples.Examples');

So there is some other cause of this linker error.

I re-installed SYS/BIOS and that got rid of the linker errors. I now have a different compilation error:

"obj/c6748-evm/c6xdsp/debug/my_biospsp_project_configuro/package/cfg/my_biospsp_project_pe674.c", line 73: fatal error: cannot open source file "ti/uia/events/DvtTypes.h"

I have added the UIA path to my XDCPATH and my BIOS PSP build environment does find this, as I get a xdc.PACKAGE_NOT_FOUND error when I remove the UIA path from my XDCPATH. So, in the C file generated, my_biospsp_project_pe674.c, this line:

#include <ti/uia/events/DvtTypes.h>

is the first include from the UIA package. This file is present in this directory, but for some reason, my build environment doesn't recognise this path here (<ti/uia/events/>).

I even tried adding the absolute path to my PATH environment variable, but I still get the same error.

Any suggestions?

Thanks

Brian,

It looks like this error is coming from the xdc.tools.configuro command. This tool uses the package path (i.e. XDCPATH) to generate the compiler include paths. Since the error message has "ti/uia/events/DvtTypes.h", which is the text entered in the source file, and not something like

"C:/.../uia_2_00_03_43/packages/ti/uia/events/DvtTypes.h"

it tells me that the XDCPATH does not include UIA. I think you need to look into where the XDCPATH is getting defined.

It can be helpful to add echo commands to the make rule which runs configuro, or remove the '@' character from the command so it will be echoed to the console.
