clang++: error: linker command failed with exit code 1
trafficstars
I was building matplotlib test app and get this error from linker. Please, could you help me? There will be deadline soon for my college app, and I can't build ever test app :( Thanks in advance!
Versions
- Python: 3.6.9, however buildozer downloaded 3.8 for app
- OS: Ubuntu 18.04.4 LTS
- Kivy: 1.11.1
- Cython: 0.29.10

# List as sections

# You can define all the "list" as [section:key].

# Let's take [app] / source.exclude_patterns.
# Instead of doing:
#
#[app]
#source.exclude_patterns = license,data/audio/*.wav,data/images/original/*
#
# This can be translated into:
#
#[app:source.exclude_patterns]
#license
#data/audio/*.wav
#data/images/original/*

# -----------------------------------------------------------------------------
# Profiles
#
# You can extend section / key with a profile
# For example, you want to deploy a demo version of your application without
# HD content. You could first change the title to add "(demo)" in the name
# and extend the excluded directories to remove the HD content.
#
#[app@demo]
#title = My Application (demo)
#
#[app:source.exclude_patterns@demo]
#images/hd/*
#
# Then, invoke the command line with the "demo" profile:
#
#buildozer --profile demo android debug

Have you tried on another machine, this happened to me once and it worked. If you don't have access to another machine, try Google Colab.
I see that you have set develop branch in buildozer.spec file, is commented by default, so I'm guessing that you first tried to build your apk, at some point you get some error and then edited buildozer.spec file and you tried to do another build with develop branch of p4a (without removing old files maybe?)...So, I suggest that you try to clean any build you have performed and try it starting from scratch. I mean, remove old buildozer compilations: buildozer android clean and then try the build again.
Note: since you got linker errors, I suspect that the linker tries to link with old compiled libraries....I cannot be certain about this, since you don't post the full log
which platform you choose? I met this error at Mac, but I changed to ubuntu , there everything ok
which platform you choose? I met this error at Mac, but I changed to ubuntu , there everything ok
I think some env has error at Mac, if changed to ubuntu, download and depends on all new
HI @obaltian and @CatTalk2!
The issue should have been fixed via https://github.com/kivy/python-for-android/pull/2586, are you still encountering it on the develop branch?
