attempting to compile keybase go-crypto on

[omac777]

Hi there, I am attempting to compile on a different cpu:
Loongson-3B1500. Here is the last-core's cpuinfo:

processor : 5
cpu model : ICT Loongson-3 V0.7 FPU V0.1
model name : ICT Loongson-3B R2 (Loongson-3B1500) @ 1199MHz
BogoMIPS : 956.04
wait instruction : no
microsecond timers : yes
tlb_entries : 64
extra interrupt vector : no
hardware watchpoint : yes, count: 0, address/irw mask: []
isa : mips1 mips2 mips3 mips4 mips5 mips32r1 mips64r1
ASEs implemented :
shadow register sets : 1
kscratch registers : 0
package : 0
core : 7
VCED exceptions : not available
VCEI exceptions : not available

It's currently on a fedora 21 distro. I tried to compile golang 1.6 on it, but unsuccessful. I am using a fc21 gcc-go
go version
go version xgcc (GCC) 4.9.3 20150626 (Red Hat 4.9.3-3) linux/mipsn64

Hello, 世界

mkdir -p /root/Code/src/golang.org/x

these are the go1.6 sources that I was unable to compile entirely. I am just copying the crypto component to see if I can get away with just that and compile it. The answer seems to be no.

Judging by the compile errors, I believe I certainly don't have the right environment setup yet to build keybase/go-crypto. I also believe I am not going through the correct steps to compile it correctly.

The hints are I really do need go1.6 installed since crypto.Signer and elliptic.P224 are part of go1.6.

I don't think this fork depends on Go 1.6, but it does depend on the standard crypto library. If you're compiling the Go standard libs yourself and seeing errors, my guess is that the problem lies there. Some of the subdirectories also have dependencies of their own, so running go get github.com/keybase/go-crypto is not sufficient. You should make sure to run go get in every subdirectory where you're about to run go build.

I believe there is a dependency on Go 1.5 stdlib at least (though probably nothing specifically from Go 1.6).

I would recommend that you try compiling Go 1.6 (or 1.5) from source, using your installed version to bootstrap.

Follow the instructions here and set GOROOT_BOOTSTRAP appropriately to your existing Go 1.4 installation.

Mr. Haven,

The go version was stated as being a redhat gcc-go version 4.9
something. I attempted to compile as you said before even trying your
crypto code, go 1.6 with the gcc-go but it failed.

I'll try compiling go 1.5 with the gcc-go on fedora 21. I can't update
anything fedora often because the great firewall of China doesn't allow
me to get much data speed and I'm limited to mirrors in China for the
loongson-3 cpu stuff. Mirrors for Loongson-3 cpu stuff outside of China
for fedora would greatly alleviate the situation, but it's a touchy
subject for loongson-3 stuff for some reasson.
