Linking Error - File not recognized

[nikomaxi]

Following error while compiling the example button.

./build/wolfssl.a: file not recognized: File format not recognized collect2: error: ld returned 1 exit status /opt/esp-open-rtos/common.mk:232: recipe for target 'build/button.out' failed make: *** [build/button.out] Error 1 make: Leaving directory '/project/examples/button'

I used the Docker version.

Try doing clean rebuild. I've seen such errors, but I do not remember what fixes that. Make sure you do not overwrite LDFLAGS anywhere.

I have done a clean rebuild but it does show the exact same error. I am using your docker version. So I deleted my docker container and cache from docker.

Heres the new error message:

My Docker Container shows now LD Flags exported

[maximkulkin]

That's not what I meant. Do make clean first, then rebuild the firmware.

I could only solve this problem by reinstalling my OS. So I can close this issue.
