Unable to Integrate mbedtls with Pico-SDK - CMake Build Fails [build] <command-line>: fatal error: mbedtls_config.h: No such file or directory #1713

Hello,

I'm encountering an issue when trying to integrate the mbedtls library with the Pico-SDK for my Raspberry Pi Pico project. The CMake build fails, and I'm unable to resolve the problem despite multiple attempts.

**Steps Taken:

Added pico_mbedtls to target_link_libraries. Verified that the Pico-SDK version is 1.4.0 or later. Followed standard procedures to initialize the Pico-SDK and add mbedtls.**

Project Configuration:

Here is my CMakeLists.txt file:

# Generated Cmake Pico project file

cmake_minimum_required(VERSION 3.13)

set(CMAKE_C_STANDARD 11)
set(CMAKE_CXX_STANDARD 17)
set(CMAKE_EXPORT_COMPILE_COMMANDS ON)

# Initialise pico_sdk from installed location
# (note this can come from environment, CMake cache etc)

# == DO NEVER EDIT THE NEXT LINES for Raspberry Pi Pico VS Code Extension to work ==
if(WIN32)
   set(USERHOME $ENV{USERPROFILE})
else()
    set(USERHOME $ENV{HOME})
endif()
set(PICO_SDK_PATH ${USERHOME}/.pico-sdk/sdk/1.5.1)
set(PICO_TOOLCHAIN_PATH ${USERHOME}/.pico-sdk/toolchain/13_2_Rel1)
if(WIN32)
    set(pico-sdk-tools_DIR ${USERHOME}/.pico-sdk/tools/1.5.1)
    include(${pico-sdk-tools_DIR}/pico-sdk-tools-config.cmake)
    include(${pico-sdk-tools_DIR}/pico-sdk-tools-config-version.cmake)
endif()
# ====================================================================================
set(PICO_BOARD pico_w CACHE STRING "Board type")

# Pull in Raspberry Pi Pico SDK (must be before project)
include(pico_sdk_import.cmake)

if (PICO_SDK_VERSION_STRING VERSION_LESS "1.4.0")
  message(FATAL_ERROR "Raspberry Pi Pico SDK version 1.4.0 (or later) required. Your version is ${PICO_SDK_VERSION_STRING}")
endif()

project(2nd C CXX ASM)

# Initialise the Raspberry Pi Pico SDK
pico_sdk_init()

# Add executable. Default name is the project name, version 0.1

add_executable(2nd 2nd.c )

pico_set_program_name(2nd "2nd")
pico_set_program_version(2nd "0.1")

# Modify the below lines to enable/disable output over UART/USB
pico_enable_stdio_uart(2nd 1)
pico_enable_stdio_usb(2nd 1)

# Add the standard library to the build
target_link_libraries(2nd
        pico_stdlib
        pico_mbedtls)

# Add the standard include files to the build
target_include_directories(2nd PRIVATE
  ${CMAKE_CURRENT_LIST_DIR}
  ${CMAKE_CURRENT_LIST_DIR}/.. # for our common lwipopts or any other standard includes, if required
)

# Add any user requested libraries
target_link_libraries(2nd 
        pico_cyw43_arch_lwip_threadsafe_background
        )

pico_add_extra_outputs(2nd)

Despite these efforts, the build process fails, and I'm unable to proceed. Could someone guide me on how to properly integrate mbedtls with the Pico-SDK?

[build] <command-line>: fatal error: mbedtls_config.h: No such file or directory

You need to add a mbedtls_config.h somewhere in your include path. Just copy an existing file from the examples to start with. https://github.com/raspberrypi/pico-examples/blob/master/pico_w/wifi/tls_client/mbedtls_config.h
