Unable to compile even the blink.ino sketch

[mikekgr]

The bellow error appeared to my Arduino IDE ( Running in Windows 10 ) :

Error compiling for board Generic ESP8266 Module.

I have ESP8266 updated from GIt Master branch

Please keep an eye what is wrong and I am here to supply you any further information you may ask.

Thanks and Best Regards,

That core_version.h looks corrupted.

[mikekgr]

Dear @devyte,
thanks a lot for your reply. What do you suggest? To erase the esp8266 folder and to the git install again?

[devyte]

That's what i would do.

[mikekgr]

Dear @devyte I have some more observations to you. After having delete the esp8266 directory and following the instructions I did the git installation. Then I just tried the Blink sketch. Unfortunately I faced the same error... Then I re delete the esp8266 directory and I copy one back up ( again, git based ) but this back up contains the git sync of 28/03/2019. So this backup is working fine, compiled the bink.ino sketch etc. Then, I did git update and sorry to say, the problem appeared again. There is something wrong in your latest commits I suppose. Please check and I am here if you need anything from me.
Thanks.

[devyte]

I just did a clean git install and Blink works as expected.
Closing as can't reproduce.

...on Ubuntu, though, not Windows, but still.

I copy one back up
contains the git sync of 28/03/2019

Are you installing via git clone or just copying the source tree? did you call get.py after your re-install?

[mikekgr]

Dear @devyte
of course I installed using git clone and following the documentation. It is very strange why this is happening... I don't know, I following your git master in my two installations ( one Windows 10, the other Windows 7 Both affected ) for two years now without problems/breakage except this one. Is there any body here with Windows to check? Please...
Thanks anyway. Not to forget, to say you a VERY BIG thanks for all the work you have done for this ESP8266 Arduino Core.

[mikekgr]

17 April 2019 was my last esp8266 git sync and successful compilation if this Info matters to you.

[devyte]

You're affected, so you should pursue. Try syncing to each commit after that to figure out which one breaks your build. That could provide a clue.

[devyte]

At a glance, suspect commit c5efb92 Apr/23/2019

[devyte]

My pythonese isn't very good, but at the very least that default arg to generate in the above commit looks fishy. Reopening.

Yes I can do that but please tell me the git commands that I have to use ( sorry, not git experience... ) OR even better using the git gui if possible...

Yes, default git_ver is wrong. 0x is unnecessary because format string below already has it.

But does this mean git is not installed / not in PATH?
@mikekgr
can you run git commands in the console (cmd.exe) at all?
does this work? git -C "E:\ARDUINO_ESP_DEV\arduino-IDE\hardware\esp8266com\esp8266\" rev-parse --short=8 HEAD

[mikekgr]

Dear @mcspr
yes after applying/editing the file tools/makecorever.py and manually change the def generate(path, platform_path, git_ver="ffffffff", git_desc="unspecified"):
everything is working fine again. Sorry I can;t work with your git -C ... command

So, your Fix default GIT_VER in makecorever.py #6044 is solving the problem.
Thanks !

But does this mean git is not installed / not in PATH?

I indeed think it is because git is not in PATH when arduino ide is started so the default value 0xffff is taken in the python script. @mcspr your #6044 seems valid to me, thanks!

@mikekgr you wouldn't have found this bug if git command were in your system path.
Can you run git in a cmd.exe shell ?

[mikekgr]

Dear @d-a-v
Yes your assumption is right, I have git ( for Windows ) installed in a so called portable installation, ( all development tools, Arduino, Git Notepad++ and many more, are all installed in an external hard drive drive and such are portable to have everything with me, provided that I will have Windows OS in the Target machine ), that means in order to execute it, I need to provide the full path. That way, I can execute it from cmd and/or using shortcuts ( Windows shortcuts is something like the symbolic links in the Unix/Linux world ).

Thanks and Best Regards,
Mike Kranidis

@mikekgr Thanks for this report and @mcspr for the fix !
