Problems building for "user/user_main.c" example..

[swingwinger]

I followed the instructions as best I can tell.. For background, building on a Linux Mint distribution, using ESP8266 NONOS SDK V2.0.0 20160810..
I made a include/user_config.local.h
I did a make (esp_mqtt/Makefile), and got the following at the bottom of the output:

xtensa-lx106-elf-gcc -L/home/matt/Espressif/ESP8266_SDK/lib -T/home/matt/Espressif/ESP8266_SDK/ld/eagle.app.v6.ld -nostdlib -Wl,--no-check-sections -u call_user_start -Wl,-static -g -O2 -Wl,--start-group -lc -lgcc -lphy -lpp -lnet80211 -lwpa -lmain -llwip -lcrypto -lssl -ljson -ldriver build/esp_mqtt.a -Wl,--end-group -o build/esp_mqtt.out

collect2: error: ld returned 1 exit status
make: *** [build/esp_mqtt.out] Error 1

Since I saw the line below had "driver" in it, and "build/driver/uart.o" appeared to have been made:
SDK_LIBS = c gcc phy pp net80211 wpa main lwip crypto ssl json driver

...So, I removed "driver" from the line above and executed make again to see what would happen... And the following came out:

I may have made an error, but haven't been able to figure out what may be missing, since I believe I'm following the build instructions properly. I had included the library in another project and had the same results, so I decided to isolate the library example to "divide and conquer", and the results were identical.

Thanks. Looks like a great project and hope I can use it. :-)

I'm also using Mint using NONOS SDK 2.1.0 and when executing make i do not get the errors you see. You have to modify the user_config.local.h not the user_config.sample.h
My output looks like:
make
touch user/user_main.c
mkdir -p build/user
mkdir -p build/driver
mkdir -p build/mqtt
mkdir -p build/modules
mkdir -p firmware

That's my bad in my description... I did make a "/user_config.local.h".

So that's not the issue. Errors I have still stand. Sorry about my error. I updated my comment above to get things on track. Not having user_config.local.h would have caused other dependency issues...

Thanks for making the effort to reply.. I do appreciate you trying to help. :-)

[harryd100]

Made a mistake too, i'm using SDK 2.1.0, corrected it above

[swingwinger]

Thanks again... ...I may try 2.1.0 then... That may help. Take me a while to try it and report back. In the meantime, maybe someone can still see something or has the same issue..
