Can't compile Minimal from platformio #5

Closed fermuch closed 3 years ago

fermuch commented 4 years ago

Hello!

I'm trying to load the library from platformio, but I get the following error:

Linking .pio/build/esp32doit-devkit-v1/firmware.elf
.pio/build/esp32doit-devkit-v1/src/main.ino.cpp.o:(.literal._Z5setupv+0x2c): undefined reference to `mDashInit'
.pio/build/esp32doit-devkit-v1/src/main.ino.cpp.o: In function `setup()':
/home/fermuch/Documentos/Dev/Work/AYVU/test-esp32/src/main.ino:26: undefined reference to `mDashInit'
collect2: error: ld returned 1 exit status
*** [.pio/build/esp32doit-devkit-v1/firmware.elf] Error 1

The sketch is the following:

#define MDASH_APP_NAME "MinimalApp"
#include <mDash.h>

#include <WiFi.h>

#define WIFI_NETWORK "MyWifiNetworkName"
#define WIFI_PASSWORD "MyWifiPassword"
#define DEVICE_PASSWORD "mDashDeviceToken"

void setup() {
  Serial.begin(115200);
  WiFi.begin(WIFI_NETWORK, WIFI_PASSWORD);
  mDashBegin(DEVICE_PASSWORD);
}

void loop() {
  delay(100);
}

And finally this is the platformio.ini file:

[env:esp32doit-devkit-v1]
platform = espressif32
board = esp32doit-devkit-v1
framework = arduino
lib_deps =
  https://github.com/cesanta/mDash.git

(It also doesn't work if I use a release instead of pulling from git)

Seems like the lib is not auto-loaded. Adding the following to platformio.ini solves the problem:

build_flags = -L.pio/libdeps/esp32doit-devkit-v1/mDash/src/esp32/ -llibmDash

also didn't work

Please see https://github.com/cesanta/mDash/issues/8

Just tested it with newest version of libraries and just the solution: build_flags = -L.pio/libdeps/<name of the lib>/mDash/src/esp32/ -llibmDash works. The solution by @cpq does not althoug the PR he is mentioning is already there.

sandikodev commented 3 years ago

right, adding build_flags = -L.pio/libdeps/esp32doit-devkit-v1/mDash/src/esp32/ -llibmDash

works like a charm

platformio.ini

[env:esp32doit-devkit-v1]
platform = espressif32
board = esp32doit-devkit-v1
framework = arduino
build_flags = -L.pio/libdeps/esp32doit-devkit-v1/mDash/src/esp32/ -llibmDash
lib_deps = cesanta/mDash@^1.2.14

pio run -e esp32doit-devkit-v1
