Hi all,
I'm trying to compile NDK with debug information and without any optimization level for C66 devices, but I think that there's a bug in the library because it's not possible to compile it without optimization.
My enviroment is composed by:
NDK: 2.22.00.06
SYSBIOS: 6.34.01.14
XDC: 3.24.02.30
CGTOOLS: 7.4.1
According to the guide "http://processors.wiki.ti.com/index.php/Rebuilding_The_NDK_Core_Using_Gmake" I've modified the file ndk.mak in the NDK root directory specifying the path of XDC_TOOLS, SYSBIOS and compiler.
Moreover I've specified in the ndk.bld the compiler options as follow:
var c6xOpts = " -mi10 -mo -pdr -pden -pds=238 -pds=880 -pds1110 -ms2 ";
/* Uncomment the following lines to build libraries for debug mode: */
c6xOpts += " -g -o0 ";
Before compilation I've cleaned the project (gmake -f ndk.mak clean), and after I've compiled the library (gmake -f ndk.mak all).
During this operation .mak files are automatically created; analyzing for example stk.ae66.mak file in /packages/ti/ndk/stack/lib the compiler options have "-g -o0" (as specified in the ndk.bld), but also -o2 option!
The following "make" code shows the compiler option for bind.c file.

This bug is platform independent; the make file for C64P and C674 have the same problem.
How can I resolve the issue? I'm not a XDC expert and I have no idea where the bug could be.
Thanks,
Matteo
