linker errors "multiple defintion of" when migrating from KDS 2.0 to 3.1

mike1974 — Wed, 17 Feb 2016 00:17:44 GMT

I had a project that built fine on KDS 2.0, but now that I have upgraded to KDS 3.1 I get the linker errors below. I followed the migrating procedure (using the KDS Upgrade Assistant) as described here: Kinetis Design Studio: Migrating KDS V2.0.0 Projects to GNU Tools for ARM Embedded (Launchpad, KDS V3.0.0)

I am building a Segger graphics library first (emWin_V528b), then linking to that library in my application (called A9950V0002). Any help would be appreciated.

Hi,

the errors show us that the same symbol is included in two files.

for example, symbol "_cleanup_r" is detected in both of these two files which are both included in your project:

to solve the problem:

- Please go to your project properties setting, remove all KDS2.0 related path and included files.

- go to IDE menu "project", "clean" to clean the old file associations.

can this help you? if not, please post your project here, we can help you check the problem directly.

Have a great day,
Jennie Zhang

Thanks Jennie, I found out the references to KDS_2.0.0 were in a file "makefile.defs". This file was used to correct a problem in KDS_2.0.0 described here:

KSDK Linker Error - Command line too long

Does KDS 3.1 still have that problem?

Hi Michael,

you are welcome.

according to KDS3.1 release note, this "Windows Command Line Limit" issue is still a known issue which is not fixed yet.

Have a great day,
