Existing MakeFile is not working on windows

[rupest]

Hi,

i am trying to build rocksdb-cloud source code on windows using existing makefile provided with source code at below location -

https://github.com/rockset/rocksdb-cloud/Makefile

i tried below command -

make rocksdbjava

Same command is working properly in Linux and Mac platform, but on windows i am getting below error -

process_begin: CreateProcess(NULL, which bash, ...) failed.
Makefile:9: pipe: No error

Did you try building through cmake? I do not think RocksDB (and by extension RocksDB-Cloud) supports Make on Windows

Hi,

Yes, i have tried to build through cmake, But i am getting few issue in that.

My objective is to generate the RocksDB-Cloud dll and link it with another internal dll.
After creating rocksdb dll when i try to link rocksdb dll with another dll then i got few errors like unresolved external symbol.

After analysis i found out that dll to dll linking happens through .lib file which generates along with .dll , and .lib file does not have all the exported symbol. As per my analysis all the symbols are not exported in rocksdb.lib file that's why errors are coming.

My question is how this issue can be resolved , do i need to put "dll_export" symbol at various places to properly link, if yes then it will be very tedious task as rocksdb-cloud code is too large.

Also i would like to know that how i can generate rocksdb.jar using cmake. as i do not see any jar after dll creation whereas in make file which is available with existing code , it generates rocksdb.jar along with shared lib(.dll or .so or .dylib) as final result.

We do not run rocksdb-cloud on Windows, so my experience is limited. I think your best bet is to work with @mrambacher who had created the last known port to Windows in this branch https://github.com/rockset/rocksdb-cloud/tree/Windows
