Forum Post: RTOS Project Build Problem with TM4C123G Launch Pad

Hi All,

 I was working on a RTOS project with TM4C123G Launch Pad.The project is Blinking an LED.Below is the code for the project;

When i initialy tried to build the project the errors were about the missing include files xdc/std.h, ti/sysbios/BIOS.h and xdc/cfg/global.h.After manually giving the paths for these files now there is another error as ;

#1965 cannot open source file "ti/targets/select.h" main.c /RTOS_1 line 86, external location: C:\ti\xdctools_3_25_03_72\packages\xdc\std.h C/C++ Problem

But the weird thing is there is no source file "ti/targets/select.h" as menitoned on line 86.

What am i doing wrong can some one help on this issue?

Thanks in advance
