thingset compile error when compiling for 8 bit AVR / Arduino

[stekgreif]

I'm trying to include the thingset library into an Arduino Project.

The setup is

• visual studio code
• platform.io
• thingset lib copied into src folder
• main.cpp replaced with example code from thingset

Compiling the code results in:

Archiving .pio/build/nanoatmega328/libFrameworkArduinoVariant.a
src/thingset_txt.c: In function 'ts_json_serialize_value':
src/thingset_txt.c:196:60: error: expected ')' before 'PRIu64'
                 pos += snprintf(buf + pos, size - pos, "%" PRIu64 ",",

Adding the build flags:

build_flags =
    -std=c++11
    -D NATIVE_BUILD
    -pthread
    -Wall
    -Wno-deprecated-declarations
    -D TS_64BIT_TYPES_SUPPORT=0```

to the platformio.ini file results in:

Compiling .pio/build/nanoatmega328/src/cbor.c.o
Compiling .pio/build/nanoatmega328/src/jsmn.c.o
avr-gcc: error: unrecognized command line option '-pthread'

Might be related to the 64 types for the AVR.

Thanks for reporting. It was indeed a bug. It's now fixed in main branch (see referenced commit above).

Can you please check again?

I still run into issues with strtoull and strtoll, I'm not sure if that's on my side. Here is the output:

/tmp/ccqrn51m.ltrans0.ltrans.o: In function `ts_json_deserialize_value.part.0':
<artificial>:(.text+0xf18): undefined reference to `strtoull'

Oops, yes, this is another one which won't work with no 64-bit support. Pushed another fix. Can you git pull again?

[stekgreif]

Nice, now it's compiling without errors. :+1: Thanks a lot.

Can't wait to get into it.

Glad to hear that. Closing the issue now.
