How should I build gsl(GNU Scientific Library) to get libgslcblas.a under ESP32-IDF environment?

Hello.

How should I build gsl or esp_gsl to get libgslcblas.a under ESP32-IDF environment?

Did you follow the 'How to use' on the page you linked?

Yes, but I got the error message

(1) idf.py add-dependency "leeebo/esp-gsl=*"
(2) idf.py create-project-from-example "leeebo/esp-gsl=*:test_project"
(3) idf.py fullclean
(4) idf.py build
(5) cd test_project
idf.py build
ninja: error: 'gsl_build/esp32s3/lib/libgslcblas.a', needed by 'test_project.elf', missing and no known rule to make it

Steps 4+5:

-DIDF_TARGET=esp32

but step 6:

-DIDF_TARGET=esp32s3

->
gsl_build/esp32s3/lib/libgslcblas.a', needed by 'test_project.elf', missing

Apparently, the library is built for the ESP32 (steps 4/5) while the test project builds for the ESP32S3 in step 6. Then the ESP32S3 build cannot find the corresponding library for the S3 because it was never built.

Try in step #6:

Code: Select all

D:\test>cd test_project
D:\test\test_project>idf.py set-target esp32
D:\test\test_project>idf.py build
