Hello, Does anyone have some example code of using building this? My steps, I'm trying to build a shared library using the thrift api
1. Checked out from SVN (trunk) 2. Made a directory called thrift, into which I place fb303.thrift, hive_metastore.thrift,hive_service.thrift,queryplan.thrift - I made changes to the include paths in the thrift files - Also changed the namespace of the queryplan thrift file to match those of - hive_metastore and hive_service (i.e Apache::Hadoop::Hive) 3. Do thrift -r --gen hive_service.thrift which creates all the cpp and .h files in gen-cpp 3. Build all the files, but this error occurs g++ -m64 -I/usr/include/R -I/usr/local/include -I. -g -DHAVE_UINTPTR_T -I./gen-cpp `pkg-config --cflags thrift` -Wall -fpic -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic -c ThriftHiveMetastore_server.skeleton.cpp -o ThriftHiveMetastore_server.skeleton.o ThriftHiveMetastore_server.skeleton.cpp: In function 'int main(int, char**)': ThriftHiveMetastore_server.skeleton.cpp:224: error: cannot allocate an object of abstract type 'ThriftHiveMetastoreHandler' ThriftHiveMetastore_server.skeleton.cpp:19: note: because the following virtual functions are pure within 'ThriftHiveMetastoreHandler': FacebookService.h:17: note: virtual void facebook::fb303::FacebookServiceIf::getName(std::string&) FacebookService.h:18: note: virtual void facebook::fb303::FacebookServiceIf::getVersion(std::string&) FacebookService.h:19: note: virtual facebook::fb303::fb_status::type facebook::fb303::FacebookServiceIf::getStatus() FacebookService.h:20: note: virtual void facebook::fb303::FacebookServiceIf::getStatusDetails(std::string&) FacebookService.h:21: note: virtual void facebook::fb303::FacebookServiceIf::getCounters(std::map<std::basic_string<char, std::char_traits<char>, std::allocator<char> >, long int, std::less<std::basic_string<char, std::char_traits<char>, std::allocator<char> > >, std::allocator<std::pair<const std::basic_string<char, std::char_traits<char>, std::allocator<char> >, long int> > >&) FacebookService.h:22: note: virtual int64_t facebook::fb303::FacebookServiceIf::getCounter(const std::string&) FacebookService.h:23: note: virtual void facebook::fb303::FacebookServiceIf::setOption(const std::string&, const std::string&) FacebookService.h:24: note: virtual void facebook::fb303::FacebookServiceIf::getOption(std::string&, const std::string&) FacebookService.h:25: note: virtual void facebook::fb303::FacebookServiceIf::getOptions(std::map<std::basic_string<char, std::char_traits<char>, std::allocator<char> >, std::basic_string<char, std::char_traits<char>, std::allocator<char> >, std::less<std::basic_string<char, std::char_traits<char>, std::allocator<char> > >, std::allocator<std::pair<const std::basic_string<char, std::char_traits<char>, std::allocator<char> >, std::basic_string<char, std::char_traits<char>, std::allocator<char> > > > >&) FacebookService.h:26: note: virtual void facebook::fb303::FacebookServiceIf::getCpuProfile(std::string&, int32_t) FacebookService.h:27: note: virtual int64_t facebook::fb303::FacebookServiceIf::aliveSince() FacebookService.h:28: note: virtual void facebook::fb303::FacebookServiceIf::reinitialize() FacebookService.h:29: note: virtual void facebook::fb303::FacebookServiceIf::shutdown() Any pointers would be appreciated. I know that a language called C++ exists :). I rarely use it. So this could be something to obvious (and silly of me). Thanks Joy
