Thanks for reporting this! Started investigating this and found another bug: printf returns -1 instead of the number of characters written, when writing to the console.

Hi, I had the same issue. I needed to remove the "#include " to compile.

[cristianCarrerasCastillo]

remover of what file? @Komse

[Komse]

Oh yes sorry this was automatically hidden, to remove the "iostream" @cristianCarrerasCastillo

[shineangelic]

+1 on this. I didn't get what "#include" I shall remove, thanks

[Komse]

For me it was the iostream include @shineangelic

[shineangelic]

thank you @Komse but that did not help. I have other weird linking errors as reported in #4663

I was able to compile commenting out _put_c method inside core/libc_replacements.c already defined in "tools\xtensa-lx106-elf-gcc\1.20.0-26-gb404fb9-2" but I guess this isn't a solution
