Anatoli Shein created HDFS-11971: ------------------------------------ Summary: libhdfs++: A few portability issues Key: HDFS-11971 URL: https://issues.apache.org/jira/browse/HDFS-11971 Project: Hadoop HDFS Issue Type: Sub-task Reporter: Anatoli Shein
I recently encountered a few portability issues with libhdfs++ while trying 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 ‘char’ from ‘int’ may alter its value [-Werror=conversion]" which does not allow libhdfs++ to be compiled as part of the codebase that treats such warnings as errors (can be fixed with a simple cast). 2. In CMakeLists.txt file (in libhdfspp directory) we do find_package(Threads) 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 libhdfs++ because they are missing multiple libraries such as protobuf, ssl, pthread, etc. This happens because we link them to a shared library hdfspp instead of hdfspp_static library. We should either link all the tools and examples to hdfspp_static library or explicitly add linking to all missing libraries for each tool/example. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
