I have succeeded building sage from source on th pi3, possibly 8 months ago.
The installation succeeded without any difficulties.
The only problem was that, due to the lack of memory, I could not run
make in parallel; the compilation took more than 24 hours, but it worked.

Re: [sage-devel] sage on raspberry pi 3 fails to build gcc

2017-05-10 Thread Francois Bissey 
Building an old gcc with a newer gcc is not recommended.
Can you give us more details (logs) of the failure with ppl
instead?

[sage-devel] sage on raspberry pi 3 fails to build gcc

2017-05-10 Thread Brent Thomas 
I have been trying to install sage on a raspberry pi 3. I didn't find a 
binary of any recent version, so I'm trying to build it from source. I've 
run into an error with sage building gcc. The relevant part of the 
gcc-5.4.0.log file is below.

Error installing package gcc-5.4.0


I've tried setting SAGE_INSTALL_GCC to no and using the default compiler 
(gcc 6.1.0) to build sage. Unfortunately, the ppl library fails to build 
when I do this as it can't find an appropriate version of the gmp library. 
(As a side note I can build ppl directly by setting the --with-gmp-prefix 
flag to the appropriate directory, but I don't know how to set this flag 
when building sage.)

Any advice on building sage on a raspberry pi would be welcome.
