> I recently encountered a few portability issues with libhdfs++ while tryi=
ng to build it as a stand alone project (and also as part of another Apache=
 project).
> 1. Method fixCase in configuration.h file produces a warning "conversion =
to =E2=80=98char=E2=80=99 from =E2=80=98int=E2=80=99 may alter its value [-=
Werror=3Dconversion]" which does not allow libhdfs++ to be compiled as part=
 of the codebase that treats such warnings as errors (can be fixed with a s=
imple cast).
> 2. In CMakeLists.txt file (in libhdfspp directory) we do find_package(Thr=
eads) however we do not link it to the targets (e.g. hdfspp_static), which =
causes the build to fail with pthread errors. After the Threads package is =
found we need to link it using ${CMAKE_THREAD_LIBS_INIT}.
> 3. All the tools and examples fail to build as part of a standalone libhd=
fs++ because they are missing multiple libraries such as protobuf, ssl, pth=
read, etc. This happens because we link them to a shared library hdfspp ins=
tead of hdfspp_static library. We should either link all the tools and exam=
ples to hdfspp_static library or explicitly add linking to all missing libr=
aries for each tool/example.
