BME680 platform IO ESP32

[peter3099]

 Hello

I'm trying to configure the BSEC library on platform io in order to use a BME680 that I have connected to an ESP32, but no matter what I do I always get

I saw the instructions for the library but I cannot find the platform txt nor I know what to put on it.

Could you please advice what's the correct way to do it?

Thanks

Please note that in your latest update you have changed the name of the library in the build_flags. You need to use "-lalgobsec" for the compiler to look for the file libalgobsec.a.

Finally I got it to  compile, thanks so much for that

In case anybody need it the final platform.ini file needs to have

If you want to have the libraries install within the project folder

build_flags =

  -I .pio/libdeps/esp32/BSEC\ Software\ Library_ID6979/src/inc

  -L .pio/libdeps/esp32/BSEC\ Software\ Library_ID6979/src/esp32

  -lalgobsec

lib_deps = 

    BSEC Software Library

One can also install the library locally and point the path to the different folders

Stay safe!

Hello Guy's,

I am using STM32f103C8T6 module as a arduino framework but I am unble to complile the below mentioned BMSC library in Platform IO.

boschsensortec/BSEC Software Library@^1.6.1480

While complaing the basic.ino file the PIO is generating belwo mentioend error.

c:/users/yusata infotech/.platformio/packages/toolchain-gccarmnoneeabi/bin/../lib/gcc/arm-none-eabi/9.2.1/../../../../arm-none-eabi/bin/ld.exe: cannot find -lalgobsec
