Hello everyone,
Has anyone tried to compiling/use the C/C++ GNU Scientific Library (GSL) as an external library or component in an ESP-IDF project?

Re: ESP-IDF GNU Scientific Library (GSL)
For other folks trying to do the same, I could solve this by adding the entire library as a Prebuilt Component
For reference follow my Project File Structure:
import_prebuilt_ project
-- components
----- gsl
-------- include
----------- <all .h files generated by default GSL build >
-------- lib
----------- libgsl.a
----------- libgslcblas.a
-------- CMakeList.txt
-- main
----- main.c
----- CMakeList.txt
-- CMakeList.txt
creating a custom component with the prebuilt library (code adapted from Jim's Depository [https://jim.studt.net/depository/?timePrefix=2022-04]
gsl/CMakeLists.txt:
notes: As there are no source files (SRCS) the library must be linked with INTERFACE attribute. See [https://esp32.com/viewtopic.php?t=15251]

Re: ESP-IDF GNU Scientific Library (GSL)
Hello.
How should I build esp_gsl to get libgslcblas.a under ESP32-IDF environment?
<esp_gsl>
https://components.espressif.com/compon ... anguage=en
thanks

Re: ESP-IDF GNU Scientific Library (GSL)
Hi dallim30,
I did not use this "esp_gsl" project to build the GSL lib.
in my case, I used the following repository that contains a copy of the latest stable version of GSL but with a cmake build system:
https://github.com/ampl/gsl
here are some steps that worked for me and my project:
conditions: Linux Environment; cmake, git and the ESP-IDF env already installed in your system.
... -> needs to meet your specific path
0) From a terminal command Clone the above repo:
make sure using the cmake in the context of ESP-IDF tools by:
1)Check your cmake version installed, must be > 3.4!
Building the lib without AMPL bindings
2)Inside the cloned repo, create a build directory and move there:
3)Initialize the build files with your desired generator: -G"Unix Makefiles" , "Ninja" etc.. defining the variables NO_AMPL_BINDINGS, GSL_DISABLE_TESTS, DOCUMENTATION Forcing the use of ESP32 Toolchain to compiling it to ESP32 architecture.
In my project, I was using the ESP32-s3 so my "DCMAKE_TOOLCHAIN_FILE" parameter was "toolchain-esp32s3.cmake"
NOTE: run the same command above twice , not sure what happens but the first time it fails!!
4)Build the resulting build files accordingly, just run "make"
5)Copy the resulted archives libgslcblas.a ..etc files and include/.h header files to the proper location in order to be used in the your ESP-IDF Project
6) follow the steps in the previous post to add the files library as a Prebuilt Component in your project.
hope it helps!
