Compile errors after clean install - git submodules errors (LINUX)

[charlesschaefer]

Hi,
I've made a new installation of Sming in my computer and tryed to run the Basic_Blink example, but it can't find the FlashString module.

When I run git submodule update at the FlashString submodule directory, it then changes the error to the http_parser library.

Looks like the Makefiles aren't able to init submodules.

This is the output when I run make (branch develop, after fresh cloning and running install.sh, Ubuntu 20.04 ):

$ make

Any idea on how to fix that?

Where is your SMING_HOME env. variable pointing to? I can see the app located at /var/www/projetos/pessoais/wifitracker/sming/Sming/samples/Basic_Blink but the compilation takes place in a completely different location /tmp/Sming/Sming/....

[charlesschaefer]

You're right, I'm sorry. That's because I was in another place when detected the error and got confused.

But to be sure the error is reproducible, I've just cloned and tryed again. Same error. Pasting the result after the first make attempt:

Hello. It looks like the build system has already found the FlashString and http-parser (and maybe other) libraries elsewhere. To find out, run make list-components. Does that help?

[charlesschaefer]

Hi @mikee47! Thanks for the tip. I don't think this is the problem. I've tryed the make list-components command:

make list-components

make: Nothing to be done for 'list-components'.

Note that the FlashString is pointing to the correct directory (I ran the command after the first make attempt), but the directory is empty:

ls -al /tmp/Sming/Tools/../Sming/Components/FlashString
total 8
drwxrwxr-x  2 charles charles 4096 jun 18 09:36 .
drwxrwxr-x 25 charles charles 4096 jun 18 09:36 ..

Today I've worked a bit more on this and after running make submodules inside Sming/Sming directory everything was installed correctly, and then I was able to build the samples again.

But there's something weird that isn't allowing the submodules to be initialized during the first make call.

I'm able to keep my work evolving here. But my concerns are about newcomers that won't be able to build after a fresh install :-(

I'll try in a clean environment to check if this problem is just mine or something that changed and messed the build system.

I'm not sure why you're using /tmp/Sming/Tools/../Sming, but if you normalise it to /tmp/Sming/Sming things will work...

[mikee47]

There is a simple fix in the build system for this, but there could be other implications for using a 'dirty' path:

diff --git a/Sming/build.mk b/Sming/build.mk

I'm not sure why you're using /tmp/Sming/Tools/../Sming, but if you normalise it to /tmp/Sming/Sming things will work...

@mikee47 I'm using this as a workaround, because my export.sh was always exporting SMING_HOME=/Sming. Only now that you pointed the problem with the dirty path that I noticed that export.sh is using $BASH_SOURCE, which isn't supportted by zsh (my default shell).

Because of this error, to not hardcode the Sming path, I've inserted this inside export.sh:

export SMING_HOME=`pwd`/../Sming

Now I tried to make in a fresh install with the correct path and it worked as expected! Thanks for your help!

To help others that use zsh I made a PR that corrects the export.sh file to use the zsh alternative to $BASH_SOURCE.
