esp-idf: Linker fails on Mac OS X with "Too many open files" error (IDFGH-1764)

Environment

• Development Kit: ESP32-DevKitC
• Kit version: v4
• Module or chip used: ESP32-WROOM-32
• IDF version: v4.0-dev-1443-g39f090a4f
• Build System: CMake
• Compiler version: xtensa-esp32-elf-gcc (crosstool-NG esp32-2019r1) 8.2.0
• Operating System: macOS 10.11.6
• Power Supply: USB

Problem Description

Invoking idf.py build on a custom project fails to compile, citing that the following libraries could not be found:

• stdc++
• libnewlib.a
• libhal.a
• lgcov
• lc
• lm
• lgcc

Expected Behavior

I expect this project to compile successfully. I am able to successfully build and flash this project on a machine running Ubuntu.

Actual Behavior

I can successfully compile and flash the hello-world program from this machine. But I cannot compile this project or the example ones for BLE (e.g. BLE server example). The linker will consistently produce this output

Steps to repropduce

1. Invoke idf.py build
2. Fails

Code to reproduce this issue

The code is quite large spanning several files. The project is structured as follows:

- main
	| - include
	|	| - ble.h
	|	| - ble_profiles.h
	|	| - wifi.h
	| - src
	|	| - ble.c
	|	| - wifi.c
- CMakeLists.txt
- component.mk
- esp_32_wifi_main.c

Files component.mk is empty and unchanged. The file CMakeLists.txt contains:

idf_component_register(SRCS "esp32_wifi_main.c" "src/wifi.c" "src/ble.c"
                    INCLUDE_DIRS "include")
