ESP32 Forum

Hi ESP32 devs...

Some background:
I am trying to port an application form TI-CC3200 to ESP32. Ass part of the process I had to convert a number of modules to accommodate the ESPO-IDF FreeRTOS changes as some ESP32 peripherals
After lots of effort I have it compiling but now the linker is failing with the following error message:

c:/msys32/opt/xtensa-esp32-elf/bin/../lib/gcc/xtensa-esp32-elf/5.2.0/../../../../xtensa-esp32-elf/bin/ld.exe: cannot find crt1-sim.o: No such file or directory

collect2.exe: error: ld returned 1 exit status

I have also included the makefile below.

All help and pointers appreciated.

PS: tried to attach the build file "build.log" but get error about an invalid extension.

By setting LDFLAGS, you overrule the esp-idf defaults. Can you try setting EXTRA_LDFLAGS instead, see if that gives the result you need?

Thanks for the help, much appreciated.

It fixed 90% of the problem, only had to add a 3rd EXTRA_LDFLAGS entry to get it to find the main appl, after that it linked..

Thanks

Hi Andre,

I'm currently trying to do exactly the same task.
I realise it's over a year since you did the change, but could you please post the content of your LDFLAGS?

Regards,

Geoff

As said before: don't mess around with LDFLAGS (unless you're 101% sure of what you do), modify EXTRA_LDFLAGS instead.
