Error compiling BSEC on ESP8266 with Arduino IDE

[Davide]

Hi everyone,
I would kindly need support for compiling a script for the ESP8266 controller with Arduino IDE.
I have a BME680 sensor connected to a NodeMCU 8266 controller and some time ago I already created a working script to read the air quality index (Arduino IDE 1.8.11 and I don't remember which version of BSEC).
Today I tried to load the same script again with Arduino IDE 1.8.12 and BSEC 1.4.7.4, but there is no way to compile it, I always find the same error. Also trying with basic example provided with BSEC library.
I read on the internet that there are problems with the IDE 1.8.12, so I tried to remove it completely (even doing folder cleaning) and to install version 1.8.9, but unfortunately without success.
I state that I have applied exactly the indications for Arduino contained in the pdf present in the BSEC package.
I replaced the arduino-builder-219.exe file, modified the platform.txt and eagle.app.v6.common.ld files as indicated and placed the libalgobsec.a files in the BSEC library folder (trying both the normal and light version).
Despite this, I find the following error:

Could anyone kindly help me?

I was running Arduino IDE 1.8.10 and ESP8266 core 2.6.3, but even after updating my setup to 1.8.11 and 2.7.1 respectively, I cannot reproduce your error yet.

From your console log I can comment that:

• "-lalgobsec" appears twice in the linker command, this is weird,
• in the same command, the linker is not including "bsec.cpp.o" nor "bme680.c.o" which I believe is causing the "undefined reference" error.

For example I would expect something more like this (changes in red) :

Please, could you share your platform.txt and eagle...etc... files?
Maybe replacing them I got it working... at least as regards the libalgobsec library.
About linker that not include "bsec.cpp.o" and "bme680.c.o" what can I do?

[handytech]

Please find attached the files used in my setup, respectively found under "C:\Users\user\AppData\Local\Arduino15\packages\esp8266\hardware\esp8266\2.7.1\platform.txt" and "C:\Users\user\AppData\Local\Arduino15\packages\esp8266\hardware\esp8266\2.7.1\tools\sdk\ld\eagle.app.v6.common.ld.h" by default.

[Davide]

Thank you handytech.

But I can't find the files... it's my problem or on the forum the files attached to the messages do not appear?

Even the logs that I tried to attach in the previous message are not in the discussion...

[handytech]

I just realized my attachment went missing too, I started investigating.
