xtensa-lx106-elf-gcc -Teagle.app.v6.ld segmentled.o -nostdlib -Wl,--start-group -lmain -lnet80211 -lwpa -llwip -lpp -lphy -lc -Wl,--end-group -lgcc -o segmentled

collect2: error: ld returned 1 exit status
<builtin>: recipe for target 'segmentled' failed
make: *** [segmentled] Error 1

does anyone know what i do wrong or what causes this error? Any help would be very much appreciated!

- Thu Dec 01, 2016 11:22 pm #58981 Have a look at my thread on building the ESP toolchain - it could be that you are using the libgcc that is built with the tools rather than the one in the SDK, and this contains functions that are in the ESP ROM. I have created a script to remove them from the library, or you can use the supplied SDK libgcc

- Fri Dec 02, 2016 2:28 am #58992 Thanks alot for your reply. I found your thread and i think that i would rather use the libgcc provided with the SDK than changing some stuff in files i am not familiar with. Could you tell me how i select the libgcc from the SDK, please?

- Fri Dec 02, 2016 3:03 pm #59022 Okay, the solution was to copy the libgcc.a file from:

esp-open-sdk/ESP8266_NONOS/lib/

to

esp-open-sdk/xtensa-lx106-elf/lib/gcc/xtensa-lx106-elf/4.8.5

Now everything is working fine! I can't believe it...
