Problem Building 10.8 on Debian Sid

[Luis Finotti]

Trying to build 10.8 from source in Debian Sid/Unstable I get

***************************************************************
Error building Sage.

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

* package:         primecountpy-0.1.1
 last build time: Mar 1 08:22
 log file:        /home/finotti/src/sage-10.8/logs/pkgs/primecountpy-0.1.1.log

It is safe to delete any log files and build directories, but they
contain information that is helpful for debugging build problems.
WARNING: If you now run 'make' again, the build directory of the
same version of the package will, by default, be deleted. Set the
environment variable SAGE_KEEP_BUILT_SPKGS=yes to prevent this.

real 6m41.764s user 64m8.295s sys 4m23.287s
make[1]: *** [Makefile:40: all-start] Error 1
make[1]: Leaving directory '/home/finotti/src/sage-10.8'
make: *** [Makefile:13: all] Error 2

This happens whether I have Debian's python3-primecountpy installed or not.

Any ideas?

you need a newer primecountpy

The easiest way out would be to use the latest 10.9.beta

I thought Sage would build the correct version.  

Now, the build worked in one of my machines, not in the other two, where I got the error above.  But they are all running Sid.  I have no idea what the difference was.

Maybe I will hold until the 10.9 comes out, if I cannot figure out the difference.

at the time of the 10.8 release, the "correct" version didn't really exist.

Also, primecount and primesieve upstream released a few versions with incorrect pkg-config files, and these won't work with any version of primecountpy.
The latest versions of primecount and primesieve are fine, but I am not sure if they made it to your Linux distro already.

It seems not yet. It's https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1128056

It might help to send them a heads up about the new upstream version.
