RocksDB中的可移植二进制文件

Question

I compile my code using the following set of flags

    LIBS += $(EXT_DIR)/librocksdb.a -lrt -lsnappy -llz4 -lz

where librocksdb.a is generated by

    PORTABLE=1 make static_lib 

I need to ship the binary to several tens of machines (all are ec2 machines with the same set of packages installed, same code/directory organisation structure).

When I try to run the code however (on the remote machine, not on the local one, where it works fine), I get the following error

Error in RockDB: Compression type Snappy is not linked with the binary.

When I compile remotely and use the binary from there, it also works fine. Libsnappy is installed on both machines.

Any thoughts on how I can fix this error and generate a binary that can be executed on multiple machines?

Answer 1

Use ldd ./yourapplication to check the library dependency on the remote machine.

Or build & install static snappy library before build your application.

I did this on an old machine, it works.
