First, it should be noted that NNCP 4.0 appears to require at least Go
1.11 or later. The 1.10 that comes with Ubuntu 18.04 LTS won't cut it
anymore.

Even after upgrading to Go 1.12, I wind up getting this when trying to
build:

skquinn@moonpatrol:~/usr/src/nncp-4.0$ make
cd /home/skquinn/usr/src/nncp-4.0/src/cypherpunks.ru/nncp ;
GOPATH=/home/skquinn/usr/src/nncp-4.0/gopath go build -mod=vendor
-ldflags "-X cypherpunks.ru/nncp.Version=4.0 -X
cypherpunks.ru/nncp.DefaultCfgPath=/usr/local/etc/nncp.yaml -X
cypherpunks.ru/nncp.DefaultSendmailPath=/usr/sbin/sendmail -X
cypherpunks.ru/nncp.DefaultSpoolPath=/var/spool/nncp -X
cypherpunks.ru/nncp.DefaultLogPath=/var/spool/nncp/log"
cypherpunks.ru/nncp/cmd/nncp-bundle
build flag -mod=vendor only valid when using modules
common.mk:51: recipe for target 'nncp-bundle' failed
make: *** [nncp-bundle] Error 1

Changing common.mk not to include -mod=vendor fares no better:

skquinn@moonpatrol:~/usr/src/nncp-4.0$ make
cd /home/skquinn/usr/src/nncp-4.0/src/cypherpunks.ru/nncp ;
GOPATH=/home/skquinn/usr/src/nncp-4.0/gopath go build  -ldflags "-X
cypherpunks.ru/nncp.Version=4.0 -X
cypherpunks.ru/nncp.DefaultCfgPath=/usr/local/etc/nncp.yaml -X
cypherpunks.ru/nncp.DefaultSendmailPath=/usr/sbin/sendmail -X
cypherpunks.ru/nncp.DefaultSpoolPath=/var/spool/nncp -X
cypherpunks.ru/nncp.DefaultLogPath=/var/spool/nncp/log"
cypherpunks.ru/nncp/cmd/nncp-bundle
# cypherpunks.ru/nncp
../../../gopath/src/cypherpunks.ru/nncp/ctx.go:115:17: invalid
operation: s.Bavail * int64(s.Bsize) (mismatched types uint64 and int64)
common.mk:51: recipe for target 'nncp-bundle' failed
make: *** [nncp-bundle] Error 2

What could I be missing?

  Greetings!

  I build it up with Go 1.10 and GOPATH=$(PWD) BUILDMOD= flags and the
  following fix: https://git.cypherpunks.ru/cgit.cgi/nncp.git/commit/?id=191a6f4e446c9c4b7c26fd746300bb775462c9bd
  However I did not extensively test its workability.
  
  >../../../gopath/src/cypherpunks.ru/nncp/ctx.go:115:17: invalid
  >operation: s.Bavail * int64(s.Bsize) (mismatched types uint64 and int64)
  
  I really tested that version on FreeBSD and forget that golang.org/x/sys
  results can differ between various systems:
  
      [...]
      unix/ztypes_linux_amd64.go:1395:        Bavail  uint64
      unix/ztypes_freebsd_amd64.go:114:       Bavail   int64
      [...]
  
  and that Bavail's differs between GNU/Linux and FreeBSD. I forcefully
  convert it to int64 and that should fix the problem.
  
  Also I added determining if Go supports modules and choosing of the
  right GOPATH/BUILDMOD options when building. That should work on both
  Go 1.10 and 1.12 systems.
  
  Thank you very much for your feedback!!! I very appreciate it!
