my OS is fedora(23) , i tried on another fedora and i got the same error .
but when i tried with Ubuntu there was no error , and building apk was sucessfull, though, the built apk file didn't lunch after installing on my android device [ crushed as soon as i opened the program ]

[AndreMiras]

That error popped again kivy/buildozer#735 and it was again Fedora (28 this time).
I'm reopening to track it here because it's the original.

Edit:
And I don't know yet how to solve. If you absolutely need to use buildozer/p4a, you can give it a try in a Ubuntu Docker container or VM. Anyway, I think we're getting closer confirming this is something on Fedora. If you feel like debugging it, you're more than welcome. I don't think any of the core developers are running Fedora so the fix will probably come from the community.

[pat1]

I am not sure to understand ...
the error in my case is
arm-linux-androideabi-gcc: error: unrecognized argument in option '-mtune=generic'
and it is true: the gcc version used in CrystaX NDK do not support this option:

If I remove "mtune" option:

so '-m64', '-fstack-clash-protection', '-fcf-protection' are not supported too.

Seems to me that this is not a Fedora specific issue.

[AndreMiras]

I get your point and I didn't investigate, but it could actually be distribution related even if we're sharing the same toolchain.
I saw before that some distribution may set some default compiler flags when you don't expect it.
I'll share if I come across it again.

Edit:
These kinda things:

python -c "import sysconfig; print(sysconfig.get_config_var('CFLAGS'))"

On Ubuntu for instance I get:

-fno-strict-aliasing -DNDEBUG -g -fwrapv -O2 -Wall -Wstrict-prototypes -Wdate-time -D_FORTIFY_SOURCE=2 -g -fdebug-prefix-map=/build/python2.7-nbjU53/python2.7-2.7.15~rc1=. -fstack-protector-strong -Wformat -Werror=format-security

There're other settings, e.g. sysconfig.get_config_var('OPT') and I know some other distributions behave otherwise, even when the toolchain is shared.

I don't know if that actually is the problem because I didn't investigate, but well it could definitely be distribution related, it won't be the first time.

[pat1]

python -c "import sysconfig; print(sysconfig.get_config_var('CFLAGS'))"

Seems distutils uses whatever the Python library was compiled with so cython use those options that are no good for cross compilation.
I am looking for how to change the compiler option for cython ...

[AndreMiras]

Nice so I made a good guess 😄
Thanks for taking a look at that issue 👍

[pat1]

in Estension you can pass extra_compile_args as argument:
Extension("hello", extra_compile_args="-Wall")
but documentation say that those args are added so it is not usefull.

Stackoverflow suggest to set OPT env variable:
https://stackoverflow.com/questions/6928110/how-may-i-override-the-compiler-gcc-flags-that-setup-py-uses-by-default

An other option is passing CFLAGS to python's configure script at build time and distutils should places CFLAGS at the head of the compiler invocation ...

I will try as soon as possible to find a solution ...

[pat1]

Nothing of the above works.
I think the only solution is to override the Cython.Distutils.build_ext class.

[pat1]

For now the only workaround I found is to remove gcc unsupported options in:
/usr/lib64/python2.7/_sysconfigdata.py
/usr/lib64/python3.6/_sysconfigdata_m_linux_x86_64-linux-gnu.py

looking for a better solution ...
any suggestions?

[inclement]

Closing as (as I understand) only a python3crystax issue. Please feel free to reopen if it also affects the new python3 recipe.

[purushottam858]

I have same issue.
kivy 1.11.1
kivymd 0.104.1
python 3.7.9

what is the solution for this error ?

[BRAINSTORMMaxB]

I had the same issue, it is solved simply:
python3 -m pip install pyjnius
