unable to build

make on a fresh checkout results in:

make: *** [snappy] Error 2

looks like we're expecting a makefile in ./deps/snappy-1.1.1, but there's nothing there :/

[jwerle]

yeah looks like make configure needs to be ran first :|

[jwerle]

Seems like snappy requires a lot just for this tool... Maybe a custom configure script to generate a HAVE_SNAPPY constant?

[heapwolf]

yeah, that's a good idea. PR anyone? I'm locked into another project at the moment.

I have run into the same / a similar issue. From within ldb/deps/snappy-1.1.1 I run the following:

$ make configure
$ make install

Directory .libs/ is indeed empty :-(. Any ideas on how to circumvent this?

[heapwolf]

Ok, i fixed this. on linux apt-get install libsnappy1 (i think) and on osx brew install snappy which makes snappy an optional dependency.

[heapwolf]

I also made it so that the make file git clones the deps instead of checking them in. Perhaps this is a better job for clib? /cc @stephenmathieson
