RC releases for Sming 4.0

[slaff]

We will start Release Candidate (RC) releases before we officially announce version 4.0. The plan for the moment is to have the following RCs

• RC1: latest code from develop. The release tag will be set in the develop branch.
  Expected release date - 29th of September.
• RC2: Leave support only for SDK >= 3.0.1. Due to the security issues found recently the older SDKs will not be supported officially.
  Expected release date - 15th of October.
• RC3: Feature freeze and bug fixes only.

Expected release date for Sming 4.0.0 is beginning of November, 2019.

Hi, just updated to latest version and in compiling my code, I receive this error:
/opt/sming/Sming/out/Esp8266/debug/lib/clib-ArduinoJson5.a(JsonObjectStream.o):(.rodata._ZTV16JsonObjectStream[vtable for JsonObjectStream]+0x38): undefined reference to `MemoryDataStream::seek(int)'

The json version is 5 into component.mk

@mikee47 Can you take a look at that issue?

[teicors]

after a make dtst-clean the configuration of the "project" is reset

/opt/sming/Sming/Arch/Esp8266/Components/esptool/esptool/esptool.py -p -b 115200 write_flash -ff 40m -fm qio -fs 512KB 0x00000 out/Esp8266/debug/firmware/rboot.bin 0x002000 out/Esp8266/debug/firmware/rom0.bin 0x100000 out/Esp8266/debug/firmware/spiff_rom.bin

How to catch the error:I

make SMING_ARCH=Esp8266 SPI_MODE=dio SPI_SIZE=4M COM_SPEED_ESPTOOL=1000000

[compiling ok]

make dist-clean

make flash

the error appers and the only way to flash the esp is a

make SMING_ARCH=Esp8266 SPI_MODE=dio SPI_SIZE=4M COM_SPEED_ESPTOOL=1000000

[mikee47]

@teicors Can you reproduce the problem by modifying one of the sample applications?

[mikee47]

after a make dtst-clean the configuration of the "project" is reset

Yes, that's by design. You can perform a clean build without resetting config like this:

make components-clean clean
make

[mikee47]

@teicors Something to check. Do git status and make sure there aren't any old files from the previous build - those should be deleted.

[teicors]

@mikee47
Sul branch develop
Your branch is up to date with 'origin/develop'.

I did

make components-clean clean
and the error disappears, even after a

make dist-clean
So I suppose something fixed after the components-clean; in my opinion the dist-clean should be stronger than components-clean or must include it.

Sorry for wasting your time.

[slaff]

in my opinion the dist-clean should be stronger than components-clean or must include it.

@teicors I agree with you.
@mikee47 If that is not already the case please include components-clean as dependency for dist-clean.

[mikee47]

dist-clean wipes the out directory entirely, trumping components-clean which only clears the currently selected build.

@teicors Did dist-clean raise any error messages? I sometimes get this in Windows if the directory is in use, in which case it needs to be re-run.

components-clean: ##Remove generated Component (user) libraries
	@echo Cleaning all Component libraries
	-$(Q) rm -f $(USER_LIBDIR)/*
	-$(Q) rm -rf $(OUT_BASE)

dist-clean: submodules-clean samples-clean docs-clean ##Clean everything for all arch/build types
	-$(Q) rm -rf out

[teicors]

@mikee47 it seems no one error during both clean (I'm working only with Ubuntu):

and

[mikee47]

The only difference I can see is that dist-clean doesn't clean your own project, only make clean does that. But I'm not sure that would explain the error you initially reported.

[teicors]

@mikee47 the errors in the dist-clean phase era related to HttpServer_FirmwareUpload and HttpServer_ConfigNetwork in the sample dir: do you agree with me ?

[mikee47]

@teicors Yes - you can ignore those particular warnings.

Windows install still not work. As in #1241 with windows 10 fresh install there is problem Extracting 'C:\Users\xxxx\AppData\Local\Temp\chocolatey\mingw-get\mingw-get-0.6.2-mingw32-beta-20131004-1-bin.tar.xz' to 'C:\tools\MinGW' hangs, and finally

ERROR: Exception calling "Start" with "0" argument(s): "Nie można odnaleźć określonego pliku"
Environment Vars (like PATH) have changed. Close/reopen your shell to
see the changes (or in powershell/cmd.exe just type refreshenv).
The install of sming was NOT successful.
Error while running 'C:\ProgramData\chocolatey\lib\sming\tools\chocolateyInstall.ps1'.

Des it mean Windows is not supported with Sming?

[mikee47]

@kwis2 I've tried the chocolatey install on a fresh Windows 10 Virtualbox installation, and whilst I don't get the same error as you there are definitely issues.

I've only ever used the manual approach outlined at https://sming.readthedocs.io/en/latest/arch/esp8266/getting-started/windows-manual.html. It says DEPRECATED but it really just needs updating (work in progress). A few points about this:

• I'd recommend using the regular 32-bit MinGW graphical installer from https://osdn.net/projects/mingw/downloads/68260/mingw-get-setup.exe. The one chocolatey attempts to install is MinGW-64 which is un-necessary as we're only producing 32-bit builds.
• If you don't have eclipse installed already, just use the latest version with C/C++ support. It doesn't have to be Luna.

[mikee47]

I'd also recommend you install GIT and pull in the latest develop. (You'll need GIT anyway as Sming uses it to pull in submodules)

[mikee47]

I've found the easiest way to install MinGW is via command line:

mingw-get install mingw32-base-bin mingw-developer-toolkit-bin mingw32-gcc-g++-bin mingw32-pthreads-w32-dev mingw32-libmingwex

This is sufficient to build for both Host and Esp8266.
