not compatible with latest avro library

[mm3l]

liserdes cannot be compiled because of the following error:

Serdes.cpp:224:71: error: conversion from 'avro::OutputStreamPtr {aka std::unique_ptravro::OutputStream}' to non-scalar type 'std::auto_ptravro::OutputStream' requested
std::auto_ptravro::OutputStream bin_os = avro::memoryOutputStream();

Serdes.cpp:242:5: error: no match for 'operator=' (operand types are 'boost::shared_ptr<std::vector >' and 'std::shared_ptr<std::vector >')
v = avro::snapshot(*bin_os.get());
^
....

It seems in the latest stable avro library (v1.9.0) auto_ptr have been replaced with unique_ptr & std::move.

That's breaking the semver rules, minor version bumps must be backwards compatible. :(

[mm3l]

how can I get the avro version that works with current libserdes? It would be wise if your readme file has links to the latest compatible avro version and not the latest stable.

avro-cpp v1.8.0

I opened #17 a while ago in an attempt to address this. (Of course, you could then argue that requiring C++11 in libserdes also warrants a major version bump...)

will this fix be available any time soon? I am also facing the same issue.

Serdes.cpp:285:30: error: conversion from ‘avro::InputStreamPtr {aka std::unique_ptravro::InputStream}’ to non-scalar type ‘std::auto_ptravro::InputStream’ requested
avro::memoryInputStream((const uint8_t *)payload, size);

Solution to Anwesha25 : To resolve above error in Serdes.cpp:285:30, update below :
std::auto_ptravro::InputStream json_is = avro::istreamInputStream(iss);
To
std::unique_ptravro::InputStream json_is = avro::istreamInputStream(iss);
