Build problems

[David Pritchard]

Hi,

I am having problems building folly (on Ubuntu). I think I've installed all the dependencies and got ./configure to work. But when I make, my first errors are here:

libtool: compile:  g++ -DHAVE_CONFIG_H -I./.. -pthread -I/usr/include -I/home/student/notes/folly/folly/ -std=gnu++0x -g -Wall -MT detail/CacheLocality.lo -MD -MP -MF detail/.deps/CacheLocality.Tpo -c detail/CacheLocality.cpp  -fPIC -DPIC -o detail/.libs/CacheLocality.o

In file included from detail/CacheLocality.cpp:17:0:

./../folly/detail/CacheLocality.h:351:3: error: a class-key must be used when declaring a friend

./../folly/detail/CacheLocality.h:351:3: error: friend declaration does not name a class or function

In file included from ./../folly/Format.h:31:0,

                 from detail/CacheLocality.cpp:26:

./../folly/FBVector.h:89:11: error: 'allocator_traits' in namespace 'std' does not name a type

./../folly/FBVector.h:93:22: error: 'A' has not been declared

Do you know how I can diagnose and fix these errors? Thanks!

What version of gcc are you using? folly requires 4.8 or higher. (gcc --version)

Wow! Thank you, I am testing out a VM image provided by the place that
I am going to teach, that didn't even occur to me. Looks like I have
to do some work but such an upgrade is possible, I will try it out.
Thanks again.

Progress! I had to change google:: to gflags:: on one line of
build/GenerateFingerprintTables.cpp to get around the first error.
Much later in the compiling process I get this error I don't know how
to diagnose:

Thanks! Sorry that this has required asking multiple questions.

Going to try downgrading my boost to 1.46.

[Tudor Bosman]

We use Boost 1.51 at Facebook and that works. What version of boost are you using? I'll see if I can pinpoint the problem.

[Tudor Bosman]

It also works with Boost 1.54 in a Ubuntu 14.04 VM that I'm using.

[David Pritchard]

Thanks, in this case I'm skipping the downgrade, I thought it might
have been important because of the README which specified the 46.

My currently installed version is 1.48.0.2.

[Tudor Bosman]

I think it's the README that's at fault, and you actually need to upgrade. I'm trying to track this down further.
