Subject: Iotivity Wiki Cross Compilation Query- port IoTivity to arm based 
platforms


Hi Joseph,



Greetings



I am new to iotivity and following the iotivity wiki guidelines for 
understanding and building framework.



I am not able to get the correct person to contact for the iotivity guideline 
provide. Found you email id so mailing you on this. Please ignore if your are 
not the correct point of contact. Please let me know to whom/how to contact for 
any Iotivity issue.





AIM - For ARM Cross Compilation. We are following the below Iotivity link.



https://wiki.iotivity.org/iotivity_porting_to_arm_based_platforms?s[]=arm&s[]=based&s[]=platforms<https://wiki.iotivity.org/iotivity_porting_to_arm_based_platforms?s%5b%5d=arm&s%5b%5d=based&s%5b%5d=platforms>



Described below Step 4 as mention in the link .



We are using arm-linux-gnueabi compiler which support build for our tager Artik 
520 - ARM Cortex A7 processer.





4) Download the UUID Header/Libraries for arm architecture from Internet or 
from linkuuid-arm.zip. Place the UUID Headers/Libraries inside IoTivity folder 
(For Eg: iotivity/extlibs/). Update the CPPPATH/LIBPATH for UUID 
Headers/Libraries in required SConscript



      -  As describe above i have followed the steps. Issue is the uuid-arm 
folder doesn't have any defulat SConscript when unzip(only header and lib 
folder) and it is not Cleary mention which is the required SConscript to add 
below lines. The uuid.so is present in the uuid-arm lib folder.

      - below are the lines which are mention need to be added.

      - i am confused on this which will be the required Sconscripts and how to 
debug this. Kindle help on this.



      For E.g.: env.AppendUnique(CPPPATH = [ '<uuid header path>'])

                env.AppendUnique(LIBPATH =  ['<uuid Library Path>'])

                env.AppendUnique(LIBS = ['uuid'])

                {{:arm_uuid_path.png?200|}}                      ----->  This 
line itself is a syntax error to add anywhere.



Build Command



scons TARGET_OS=linux TARGET_ARCH=arm TARGET_TRANSPORT=IP SECURED=0 RELEASE=1 
TC_PREFIX=arm-linux-gnueabi- TC_PATH=/usr/arm-linux-gnueabi/bin



ERROR
