Compilation fails with "leveldb/decompress_allocator.h: No such file or directory"

[phunni]

When I try and compile the latest version I get:

`/home/paul/mcpe_viz/mcpe_viz.cc:206:10: fatal error: leveldb/decompress_allocator.h: No such file or directory

include "leveldb/decompress_allocator.h"

      ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Sounds like you need to do a 'git pull' on leveldb-mcpe

[phunni]

I did, but it wouldn't compile, so I downloaded the latest tag. Obviously not new enough...

[Plethora777]

Tell me what's failing w/ leveldb-mcpe

[Plethora777]

Should be able to just do a new 'git clone' on the current leveldb-mcpe and be good to go. Might need to fiddle with zlib.h include (just edit the source file to change from zlib/zlib.h to zlib.h)

[phunni]

OK - I'll give that a try. Thanks.

Here's the error - not sure it's to do with a zlib include:

`g++ -DDLLX= -I. -I./include -std=c++0x -fno-builtin-memcmp -pthread -DOS_LINUX -DLEVELDB_PLATFORM_POSIX -DLEVELDB_ATOMIC_PRESENT -DSNAPPY -O2 -DNDEBUG -fPIC -c db/snappy_compressor.cc -o out-shared/db/snappy_compressor.o db/snappy_compressor.cc:6:10: fatal error: snappy/snappy.h: No such file or directory

include <snappy/snappy.h>

      ^~~~~~~~~~~~~~~~~

compilation terminated. make: *** [Makefile:414: out-shared/db/snappy_compressor.o] Error 1 `

[Plethora777]

That's odd - it should not try to compile w/ snappy unless you actually have snappy installed.

Let's try a compilation in a new dir to see how that goes:

mkdir new-leveldb-mcpe cd new-leveldb-mcpe git clone https://github.com/Mojang/leveldb-mcpe.git cd leveldb-mcpe make

If that works (which it should :)) you should remove your old mcpe_viz/leveldb-mcpe/ subdir and create a fresh one.

I managed to get it compiling by simply removing -DSNAPPY and now all is happy!

[Plethora777]

Super! I'll close this.
