Build failed on ESP_IDF

[boonkey]

Hardware: (irrelevant for this issue)

Board: M5 ESP32CAM
Core Installation/update date: latest
IDE name: IDF-with Arduino
Flash Frequency: 40
Flash size: 4 MB
PSRAM enabled: ?no?
Upload Speed: ?115200?
Computer OS: Ubuntu 18.04.3 LTS

I'm trying to add the HTTPClient header file (and all associated files, libraries, methods, etc.) to M5's WIFI_STA project (link) in order to be able to send GET requests.

I followed the steps in the docs (doc):

1. cloned the repo into components/ as arduino/
2. tried to make
   I had the exact same issue as WiFiClientSecure make issue #2154, so I followed the instructions there to solve.
3. Component Config -> mbedTLS -> TLS Key Exchange Methods -> [*] Enable pre-shared-key ciphersuits [*] Enable PSK based ciphersuite modes
   I now still have building issues, appearing unrelated to the previous one.

please help me to solve this issue.
Thanks

you forgot to mention the ESP-IDF version, but I will guess it's not 3.2 :)
Arduino tracks IDF branch release/3.2 currently

[boonkey]

I changed ESP-IDF version to release/3.2 as instructed :
cd ~/esp/esp-idf; git checkout release/v3.2; git submodule update --init --recursive;

I went and tried to make again, but it still failed:
In file included from /home/user/esp/m5stack-cam-psram/wifi/wifi_sta/main/main.c:18:0: /home/user/esp/m5stack-cam-psram/wifi/wifi_sta/components/arduino/libraries/HTTPClient/src/HTTPClient.h:32:18: fatal error: memory: No such file or directory compilation terminated. /home/user/esp/esp-idf/make/component_wrapper.mk:285: recipe for target 'main.o' failed make[1]: *** [main.o] Error 1 /home/user/esp/esp-idf/make/project.mk:530: recipe for target 'component-main-build' failed make: *** [component-main-build] Error 2

just to be sure, I've DELETED EVERYTHING and started on a clean slate.
I have done most of my checking make commands without extra threads

Maybe I had something done wrong. I'm writing this as I'm doing it, so everything I write is what has just happend:

Download ESP-IDF

1. cd ~/esp
2. git clone -b release/v3.2 --recursive https://github.com/espressif/esp-idf.git
3. cd ~/esp/esp-idf
4. git submodule update --init --recursive

Clone the M5stack repo on which I'm basing my project:

1. cd ~/esp
2. git clone https://github.com/m5stack/m5stack-cam-psram.git
3. cd ~/esp/m5stack-cam-psram/wifi/wifi_sta
4. changed WiFi credentials to connect to my WiFi.
5. make menuconfig && make flash

after setting menuconfig as required, everything has compiled and ran as expected

Clone this library into my project (following instruction from To use as a component of ESP-IDF :

1. cd components && \ git clone https://github.com/espressif/arduino-esp32.git arduino && \ cd arduino && \ git submodule update --init --recursive && \ cd ../.. && \ make menuconfig

2. I got a build error:
   /home/dan/esp/m5stack-cam-psram/wifi/wifi_sta/components/arduino/libraries/WiFiClientSecure/src/ssl_client.cpp: In function 'int start_ssl_client(sslclient_context*, const char*, uint32_t, int, const char*, const char*, const char*, const char*, const char*)':

/home/dan/esp/esp-idf/make/project.mk:530: recipe for target 'component-arduino-build' failed
make: *** [component-arduino-build] Error 2

I used the solution in #2154
3. make menuconfig
4. Component Config -> mbedTLS -> TLS Key Exchange Methods ->
[*] Enable pre-shared-key ciphersuits
[*] Enable PSK based ciphersuite modes

5. make clean && make

The make command failed with this error:
Python requirements from /home/dan/esp/esp-idf/requirements.txt are satisfied. /home/dan/esp/esp-idf/components/partition_table/Makefile.projbuild:60: warning: undefined variable 'quote'

Partitions defined in '/home/dan/esp/m5stack-cam-psram/wifi/wifi_sta/components/arduino/tools/partitions/default.csv' occupy 4.0MB of flash (4194304 bytes) which does not fit in configured flash size 2MB. Change the flash size in menuconfig under the 'Serial Flasher Config' menu.

make: *** [/home/dan/esp/m5stack-cam-psram/wifi/wifi_sta/build/default.bin] Error 2

I've verified that my device (ESP32CAM) has enough flash to 4MB, which it does.
6. make menuconfig

7. Serial flasher config -> Flash size -> 4MB

8. make clean && make

compilation passed without errors. I re-checked by running step 8 numerous times, all passing.

9. make -j6 flash monitor

run passed without errors

Add use of this library to my code:

using instructions from here

1. add includes to code:
   #include <WiFi.h>
#include <HTTPClient.h>

2. make clean && make

this time I got LOTS OF ERRORS

3. I found bug #116 and followed instructions: change all my C files to C++

4. make clean && make

resulted in lots of /home/dan/esp/m5stack-cam-psram/wifi/wifi_sta/main/main.cpp:73:1: sorry, unimplemented: non-trivial designated initializers not supported errors. solving them included:
a. change all non-trivial designated initializers
b. adding extern "C" to void app_main()
c. changing CMakeLists.txt

so far so good, the code compiled and ran

5. adding code section from the instructions, and make.

code is compiling. This bug is over.

@me-no-dev for future times, please don't dismiss so easily. the problem wasn't compiler version (but a whole different sets of problems)

Thanks for this "tutorial", I ran to the same problem with my port. Since this is a config problem, why is this not catched in the code with a #ifndef XY #error A GOOD DESCRIPTION ....

@Boldie Why not send in a PR to add those sort of config checks to the client code ....
