Re: [gpsd-users] Building the master branch and the split24 option

[Roy Barkas]

Hang on, I just noticed that when I run sudo scons udev-install after a master build where the errors are reported, the install fails with:

Install file: "gpsdecode" as "/usr/local/bin/gpsdecode"

chrpath -r "/usr/local/lib" "/usr/local/bin/gpsdecode"

`/usr/local/bin/gpsdecode' probably isn't an ELF file.

elf_open: Exec format error

scons: *** [/usr/local/bin/gpsdecode] Error 1

scons: building terminated because of errors.

This may mean that when I was testing the split24 with gpsdecode I was actually running the 3.9 version rather than the newly built master version.

I'll wait to do any further split24 testing until we get the build problem figured out.

Maybe.  Here's what I see:

Tell me if that reproduces for you.
