Hi All,

I followed the setup as described in your post. When I try to compile the Hello_world example, I get the following errors:

hi paul

note, the plugin is for CMake based projects (4.x and above)
it means, you need ESP-IDF 4.x and above
..

it looks like

Code: Select all

..
Some Python dependencies must be installed.  Check above message for details.
..
you miss few (Developer) things on your freshen Debian 10.1.0 image.
did you install these tools and other tools after the install?
you need it first.

cause it start at 4.x perhabs you have a note from the readme first
Install Prerequisites

example:

Code: Select all

sudo apt-get install git wget libncurses-dev flex bison gperf python python-pip python-setuptools python-serial python-click python-cryptography python-future python-pyparsing python-pyelftools cmake ninja-build ccache
note:
CMake version 3.5 or newer is required for use with ESP-IDF.
Older Linux distributions may require updating, enabling of a “backports” repository, or installing of a “cmake3” package rather than “cmake”.


also python says, you must install few dependenies,
it is in the requirements.txt file example here

hope this helps for orientation and further steps.

best wishes
rudi ;-)

paulvdbergh@debian-10:~$
So I think I have the right tools installed ? (The documentation mentions Python 3.7, my install reports 2.7, is this the problem?)

Code: Select all

paulvdbergh@debian-10:~$ python --version
Python 2.7.16
How can I use the esp-idf/requirements.txt file to make it usefull ?

Thanks for your appreciated response,

Paul

Edit:

Code: Select all

paulvdbergh@debian-10:~$ python3.7 --version
Python 3.7.4

Hi Paul,
Thanks for reporting. The issue is related to the expansion of PATH environment variable by the plugin. We will have the fix for this issue soon. For now, if you go into Preferences > C/C++ > Build > Environment and edit PATH environment variable value, you will see that it ends with ":$PATH" string. You can replace this with ":/usr/local/bin:/usr/bin:/bin" (or whatever your system PATH string is). Then the build should succeed.

Hi Paul,
u're welcome :)

to your question

usually the idf.py / IDF / esptool is making this call byself for each requirement
also the install process is now automatically more the more, but for your info:
example:

Code: Select all

pip install --user -r requirements.txt
this is example more the more not need to do this by hand,
espressifer's work hard for do for us the most steps more the more automatically processed

you find a text passage of this customized by hand doings in an other help, example here

we have more different requirements in the IDF - it is depending which and what will/is/must be installed.
it is usually an automatically process.

can be, that the missing (..:$ENV{PATH}:..) Var like ESP_igrr mentioned is the basicly reason for it,
and some tools was not found
you can check the log for more example ( taken from your hello_world_example )
/home/paulvdbergh/eclipse-workspace/Hello_world/build/CMakeFiles/CMakeOutput.log

hope this helps for info and describe what requirements.txt do/for what it is.

best wishes
rudi ;-)

Hi ESP_igrr,

Your workaround :

Code: Select all

For now, if you go into Preferences > C/C++ > Build > Environment and edit PATH environment variable value, you will see that it ends with ":$PATH" string. You can replace this with ":/usr/local/bin:/usr/bin:/bin" (or whatever your system PATH string is). Then the build should succeed.
did the job.

Thanks. Any idea when this bug will be fixed?

Kind regards,

HI All,

After a long time as a reader only, this post invite me to write my first port.
Thank you for the plugin information, however I'm facing some issues, I follow all steps and I'm able to compile and flash from Eclipse on Windows 10.
However I did skip the "Esspressif IDF Tools Manager -> Install Tools" because it raise the follow error:

I'm not a Java expert, however I try to debug the code using the test methods introduced by developers then I find the follow error:

Code: Select all

java.lang.NoSuchMethodException: java.util.prefs.WindowsPreferences.WindowsRegOpenKey(int, [B, int)

So, anyone has any suggestion to handle that issues?
Any help and thougths are very welcome.

Sorry for long post and thank you advance.
