Sage 8.3 Build Fails on Debian Sid

[Luis Finotti]

I've just tried to compile sage 8.3 from source on Debian Sid/Unstable.  I don't see much in the screen right before it fails:

Error building Sage.

The following package(s) may have failed to build (not necessarily
during this run of 'make all-start'):

* package: pip-9.0.3
  log file: /usr/local/sage-8.3/logs/pkgs/pip-9.0.3.log
  build directory: /usr/local/sage-8.3/local/var/tmp/sage/build/pip-9.0.3

The build directory may contain configuration files and other potentially
helpful information. WARNING: if you now run 'make' again, the build
directory will, by default, be deleted. Set the environment variable
SAGE_KEEP_BUILT_SPKGS to 'yes' to prevent this.

make[1]: *** [Makefile:33: all-start] Error 1
make[1]: Leaving directory '/usr/local/sage-8.3'
make: *** [Makefile:13: all] Error 2

Any help would be greatly appreciated.

Thanks for the reply!

Done.  Let me know if you have any suggestions...

[Dima Pasechnik]

one can see in your log:

UnicodeDecodeError: 'ascii' codec can't decode byte 0xe1 in position 16: ordinal not in range(128)

this suggests non-ascii chars in some of your paths, or something "interesting" with your locale.

Can you try running

LC_ALL=C ./sage -i pip

to see if this succeeds.

[Luis Finotti]

Thanks for you help!

It still fails:

besides it's being gcc 8.2, and AFAIK nobody ever built Sage with gcc 8, I don't see anything strange.

Not sure what data pip installer is choking on here. Hostnames with non-ascii chars?

[pip-9.0.3]   File "/usr/local/sage-8.3/local/lib/python3.6/encodings/ascii.py", line 26, in decode
[pip-9.0.3]     return codecs.ascii_decode(input, self.errors)[0]

This is actually strange - why is it python3.6?

Are you trying to build a python3-based Sagemath?

(python3 support is very much work in progress in Sage)

No.  I just downloaded and extracted the source, did "export MAKE="make -j4 -l5.5" and then "make", like I usually do.  I certainly did not try to do anything different/novel.

I don't think so:

$ file /etc/hosts
/etc/hosts: ASCII text

And I don't think there is any weird directory/file name.  (At least, I know not to do it.)

About GCC, I have no idea when it was updated on Sid.  I have GCC 7 installed also.  I tried compiling with GCC 7, but it failed (maybe I did not have the correct command -- I just did what "Google told me"):

To switch to non-default C/C++ compiler, you need to run

./configure CC=gcc-7 CXX=g++-7

and most probably

make distclean

before starting the build

Thanks for your continued support!  Unfornuately, GCC 7 did not work and gave the same error...

[Dima Pasechnik]

well, you can try debugging it. Modify pip tarball in upstream/, update its checksum, run sage -i pip, rinse and repeat...

[Dima Pasechnik]

perhaps it even suffices to insert prints in appropriate places in local/

[Dima Pasechnik]

the latest beta, 8.4beta1, updates pip package.
it's the way to go anyway.

[Luis Finotti]

I'm sorry to have to ask, but could you tell me how to get 8.4beta1 source?

[Dima Pasechnik]

you can clone

https://github.com/sagemath/sage.git

and then checkout  'develop' branch.

This is where the latest beta/release candidate is normally mirrored.

This is perfectly fine with gcc-8.2.0 that I have on my machine. And
building Sage with it since long now. I don't see any reason to
switch to another compiler.

Sorry, my bad. My own student did build  Sage with gcc 8.1...

pip chokes on parsing /etc/$DISTRO-release (for whatever Linux $DISTRO you are yousing). Please post the file content.

Good catch!  Indeed, that file had UTF-8 characters.  Removing them resulted in a successful build!  (8.4beta1 had also failed.)

Thanks all for the great support!

[Volker Braun]

IMHO thats a bug that we should report to pip upstream... can you do that with your distribution details?

[Dima Pasechnik]

seems like we look at a tip of py2/3 string/unicode iceberg mess... :-)
