fix CI travis , add esp32

[tablatronix]

Can someone fix travis in developement branch ?

[tzapu]

what's the minimum arduino ide and esp8266 sdk this compiles for now?

cheers

[tablatronix]

I have no idea
I would say when they added C++11

And esp8266 should still be the same, although its bugged as shit before 2.4.0

[tzapu]

just tried with latest stable and arduino 1.8.5 but it fails miserably with this error

<command-line>:0:7: error: token "{" is not valid in preprocessor expressions
/home/travis/.arduino15/packages/esp8266/hardware/esp8266/2.4.0/cores/esp8266/core_esp8266_si2c.c:40:5: note: in expansion of macro 'F_CPU'
 #if F_CPU == FCPU80
     ^

 #if F_CPU == FCPU80
     ^
exit status 1

which i have no idea how to fix

[tablatronix]

yeah that makes no sense, ill poke around

[tablatronix]

It looks like the compile string is maybe not replacing vars properly

-DF_CPU={build.f_cpu} <-- is it literally defining F_CPU as {build.f_cpu} ?

from platform..txt recipe

## Compile c++ files
recipe.cpp.o.pattern="{compiler.path}{compiler.cpp.cmd}" {compiler.cpreprocessor.flags} {compiler.cpp.flags} -DF_CPU={build.f_cpu} -DARDUINO={runtime.ide.version} -DARDUINO_{build.board} -DARDUINO_ARCH_{build.arch} -DARDUINO_BOARD="{build.board}" -DARDUINO_VARIANT="{build.variant}" {compiler.cpp.extra_flags} {build.extra_flags} {includes} "{source_file}" -o "{object_file}"

[tablatronix]

Can you debug the entire command, see if all boards.txt build.conf are missing ?

I don't know anything about travis

[tzapu]

something wrong with travis now, won t give out any logs :))

[tablatronix]

whats the status on this ?
Did esp32 ever get added also?
