CMake iOS build for Firebird 3
Egor Pugin announced on Firebird-Devel list :
With new CMake 3.2.1 it is possible to successfully build Firebird for
iOS platform using CMake.
Updated instructions for iOS build available at
https://bitbucket.org/egor_pugin/firebird_cmake/wiki/Home
The last issue you encounter during building is duplicate symbol error
from clang. It is related to class DatabaseDirectoryList in anonymous
namespace. This class exists in files: src/jrd/jrd.cpp and
src/common/db_alias.cpp.
For my tests I added last underscore symbol to one of those classes
and the build completes.

GSOC 2015 Finish Firebird Libreoffice driver integration
There is a medium difficulty task for a c++ programmer in current GSOC 2015
The Firebird driver for LibreOffice was started, and is mostly functional, in a previous GSoC, but it needs finishing and polishing. The main remaining issue is that the firebird data format embedded in the .odb file is endianess-dependent. The idea is to switch to Firebird’s “archive” format that is not.
Required skills / knowledge
C++, SQL, Reading other’s code, capacity to work autonomously.
Difficulty
medium

BenchmarkSQL for Firebird
Roman Simakov announced BenchmarkSQL for Firebird
I’ve ported BenchmarkSQL for Firebird. It’s TPC-C test working via
JDBC and support PostgreSQL, Oracle, DB2 and now Firebird.

I could run it locally and maybe it could be useful to know where we
are comparing to other DBMSs.
Please share you investigations.
