I am having problems with ld (using IDE 1.6.12) collect2. says error 5 and that is all info I can get. not very helpful.
Interesting point: My sketch was built properly all the time. then I updated some boards as suggested by the IDE and then this error came up. no changes in the sketch itself at all.
I looked around in the temp build directory but could not find any linker output file. Is there a way to tell the linker to write such file or the build process not to delet this file ? I guess there must have been a file once that collect2 was able to scan through.
any idea appreciated. tia
