"configure: error: C compiler cannot create executables See `config.log' for more details" (# Command failed: ./distribute.sh -m "kivy" -d "pollygot")

[hebozhe]

Once again, the relevant details:

• On Windows 10.
• Built a set of four py files (one main.py) all in Python 2.7.9.
• No longer sharing the file from Windows to the VM, instead downloaded all of the relevant files from Dropbox.
• Using manually downloaded Miniconda2 as my interpreter.
• Miniconda2 and all other files loaded in C:\Users\Me\Miniconda2...
• Downloaded Kivy and other non-built-in modules from Windows command prompt.
• Using Kivy Buildozer VM on Oracle VM VirtualBox.

Okay, back so soon, but here was the subsequent error:

configure: error: C compiler cannot create executables
See `config.log' for more details
# Command failed: ./distribute.sh -m "kivy" -d "pollygot"
# 
# Buildozer failed to execute the last command
# The error might be hidden in the log above this error
# Please read the full log, and search for it before
# raising an issue with buildozer itself.
# In case of a bug report, please add a full log with log_level = 2

The only places in my buildozer.spec file (or anywhere else, for that matter) where the string "pollygot" appears:

[app]

# (str) Title of your application
title = PollyGot

# (str) Package name
package.name = pollygot

# (str) Package domain (needed for android/ios packaging)
package.domain = pollygot.test

I tried adding python2 and cython to the buildozer.spec requirements, but it threw the same error. Where ought I go from here?

Also, what details should I be looking for in config.log, and where do I find it on the Buildozer VM?

[hebozhe]

Solved it myself. Here's what I did:

1. I totally restarted, as in deleted and reinstalled, the Kivy/Buildozer VM because I wasn't sure what changes I had made in my troubleshooting efforts.
2. Then, I ran the "buildozer android_new debug" command.
3. It threw some error, but got past the one mentioned in the original post.
4. Then, I ran the "buildozer android debug" command from the same place, and the APK was compiled and completed.

The APK didn't work, though. At least it compiled, so I'll close this one.
