ESP8266 Compiling with xtensa-freertos
af0815:
I have created a crosscompiler for xtensa and the lx106 (ESP8266). But i am not able to compile a hello world. Exactly the compiling will work, but not the linking.
--- Code: Text [+][-]window.onload = function(){var x1 = document.getElementById("main_content_section"); if (x1) { var x = document.getElementsByClassName("geshi");for (var i = 0; i < x.length; i++) { x[i].style.maxHeight='none'; x[i].style.height = Math.min(x[i].clientHeight+15,306)+'px'; x[i].style.resize = "vertical";}};} ---@echo onset IDF_PATH=C:\data\esp\ESP8266_RTOS_SDKcd C:\data\lazdev\xtensa\projectsC:\data\lazdev\xtensa\fpc\bin\i386-win32\ppcrossxtensa -va -Furtl/units/xtensa-freertos/ -Tfreertos -XPxtensa-lx106-elf- -O3 -Wpesp8266 HelloWorld2.lpr -Fl~/esp/xtensa-lx106-elf-libs/ -FlC:\data\esp\ESP8266_RTOS_SDK\components/esp8266/lib -FlC:\data\esp\ESP8266_RTOS_SDK/components/newlib/newlib/lib -Fl~/esp/xtensa-lx106-elf/xtensa-lx106-elf/sysroot/lib/ pause My SDK is under c:\data\esp, not c.\esp to hold my root clean.
If i try my HelloWorld2.lpr to compile i get the following message.

Maybe i have not given all need information to the crosscompiler. But i created my HelloWorld according the wiki https://wiki.lazarus.freepascal.org/Xtensa point 1.2.4 to test my crosscompiler.
Any hints how to get this working?

I currently work with him.
But the new one is with core RISK-V and may be good to transfer to him

which is 'him' ? I am talking about ESP8266 - not him (or her)
trev:
Dial back the attitude mate.
The previous poster, who was trying to help you and whose grasp of English pronouns or translation software may not be perfect, was suggesting that the new ESP8266s have RISK-V cores which may or may not help you.

Sounds like a wrong path. Maybe confused between backslash and frontslash?
