Hi
I’m a new platformio user with a familiar problem: The length of a compiler command exceeds the maximum allowable command length for my windows 11 system. I realize this is basically a limitation of the windows command line but am hoping someone may have a workaround.
I started with the espidf-ulp-pulse example and tried to add the bits for wifi and mqtt as follows
CMakeLists.txt
cmake_minimum_required(VERSION 3.16.0)
list(APPEND EXTRA_COMPONENT_DIRS $ENV{IDF_PATH}/examples/common_components/protocol_examples_common)
include($ENV{IDF_PATH}/tools/cmake/project.cmake)
project(espidf-ulp-pulse-new)
src/CMakeLists.txt
idf_component_register(SRCS "ulp_example_main.c"
INCLUDE_DIRS ""
REQUIRES driver soc nvs_flash ulp
PRIV_REQUIRES mqtt esp_wifi
)
#
# ULP support additions to component CMakeLists.txt.
#
# 1. The ULP app name must be unique (if multiple components use ULP).
set(ulp_app_name ulp_main)
#
# 2. Specify all assembly source files.
# Files should be placed into a separate directory (in this case, ulp/),
# which should not be added to COMPONENT_SRCS.
set(ulp_s_sources "../ulp/pulse_cnt.S" "../ulp/wake_up.S")
#
# 3. List all the component source files which include automatically
# generated ULP export file, ${ulp_app_name}.h:
set(ulp_exp_dep_srcs "ulp_example_main.c")
#
# 4. Call function to build ULP binary and embed in project using the argument
# values above.
ulp_embed_binary(${ulp_app_name} "${ulp_s_sources}" "${ulp_exp_dep_srcs}")
target_compile_options(${COMPONENT_LIB} PRIVATE "-Wno-format")
By my count the command is just over 9K in length. Interestingly removing mqtt from the REQUIRES line shortens it just enough to come in under the 8K windows command line limit.
I tried adding the script suggested as a workaround at 2021 Issue
“Command line is too long” while building large project under Windows
but that python script would not run on my system.
I’m using latest versions of all systems as installed by the VSCode extension system:
Windows 11 Home Edition, fully patched
VSCode version 1.101.1
Platform IO version 3.3.4
ESP-IDF v5.1.2
