Support for C++ build using Micrsoft Visual Studio on Windows
-------------------------------------------------------------
Key: AVRO-1015
URL: https://issues.apache.org/jira/browse/AVRO-1015
Project: Avro
Issue Type: Improvement
Components: c++
Environment: Windows
Reporter: Thiruvalluvan M. G.
Assignee: Thiruvalluvan M. G.
Fix For: 1.6.2
At present, Avro C++ builds on Cygwin but does not build natively for Windows
using Visual Studio. The main stumbling block has been integration with Flex
and Bison. Now that AVRO-956 removed dependence on Flex and Bison, we should
start supporting Visual Studio Builds. A few issues need to be addressed, which
the forthcoming patch take care of:
- signed to unsigned conversion and vice-versa should be explicit. Otherwise
the compiler generates warnings.
- Floating point literals unless suffixed with f are considered double. The
compiler warns about loss of precision, even though the actual values don't
really need double.
- Taking &v[0] to obtain the pointer to the underlying array in a vector fails
in debug mode if the size of the vector is 0. Similar thing happens for strings
as well.
- If a function or a class is exposed outside a DLL, __dllexport should be
specified similarly if they are used outside the DLL, __dllimport should be
specified.
- min and max are both functions in Standard C++ library and macros in Windows
standard library, which causes conflict.
- The Unix file handling does not work in Windows. It needs its own method.
- Boost library and TR1 clash in a couple of places especially in "make_shared".
