solaris 10 gcc 4.8.2上-lpthread和-pthreads之间的区别是什么？

我的应用程序在solaris sparc中运行并使用g 4.8.2构建，版本细节是：

solaris : SunOS t1000 5.10 Generic_141444-09 sun4v sparc SUNW,Sun-Fire-T1000

g++ : gcc version 4.8.2 (GCC)

第一次，我使用boost :: thread并构建应用程序，如下所示：

g -pthreads -lsocket -lnsl -o dist / Debug / GNU-Solaris-Sparc / accagent build / Debug / GNU-Solaris-Sparc / PassengerFlowThread.o build / Debug / GNU-Solaris-Sparc / AccDataTaker.o build / Debug /GNU-Solaris-Sparc/AccCache.o build / Debug / GNU-Solaris-Sparc / Acc.o build / Debug / GNU-Solaris-Sparc / DeviceStatusThread.o build / Debug / GNU-Solaris-Sparc / EntityAccessFactory.o build /Debug/GNU-Solaris-Sparc/BasicSmith.o build / Debug / GNU-Solaris-Sparc / CBThread.o build / Debug / GNU-Solaris-Sparc / SegmentedDeviceStatus.o build / Debug / GNU-Solaris-Sparc / AccInfo . pb.o build / Debug / GNU-Solaris-Sparc / CBException.o build / Debug / GNU-Solaris-Sparc / TimerThread.o build / Debug / GNU-Solaris-Sparc / STEModbusRequest.o build / Debug / GNU-Solaris- Sparc / SegmentedPassengerFlow.o build / Debug / GNU-Solaris-Sparc / ModbusConfigMap.o build / Debug / GNU-Solaris-Sparc / DeviceStatusSmith.o build / Debug / GNU-Solaris-Sparc / StationModeThread.o build / Debug / GNU- Solaris-Sparc / AccMain.o build / Debug / GNU-Solaris-Sparc / ModbusTcpServer.o build / Debug / GNU-Solaris-Sparc / PassengerFlo wSmith.o build / Debug / GNU-Solaris-Sparc / CacheKeeper.o build / Debug / GNU-Solaris-Sparc / SegmentedStationMode.o build / Debug / GNU-Solaris-Sparc / AccInfoImpl.o build / Debug / GNU-Solaris- Sparc / AsioClient.o build / Debug / GNU-Solaris-Sparc / AccDataSenderThread.o build / Debug / GNU-Solaris-Sparc / ModbusRequest.o build / Debug / GNU-Solaris-Sparc / AccDataSender.o build / Debug / GNU- Solaris-Sparc / StationModeSmith.o build / Debug / GNU-Solaris-Sparc / AccDataSenderTcpServer.o build / Debug / GNU-Solaris-Sparc / ModbusException.o build / Debug / GNU-Solaris-Sparc / CacheImpl.o build / Debug / GNU-Solaris-Sparc / EventManagerThread.o build / Debug / GNU-Solaris-Sparc / CacheKeeperThread.o build / Debug / GNU-Solaris-Sparc / log.o build / Debug / GNU-Solaris-Sparc / AccAgent.o -L ../../../cots/poco_1_4_6/lib/SunOS/sun4v -L ../../../ cots / protobuf_2_4_1 / src / .libs -L ../../../ cots / boost_1_55_0 / stage / lib -L ../../../ tools / lib -L ../../../ cots / oracle / 1120 / solaris10_sparc / lib -L ../../../ sdk -L ../../../ cots / RCF_2_0_0_2670 / library -lposix4 -lboost_program_options -lboost_syst em -lboost_filesystem -lboost_thread -lclntsh -lprotobuf -lRCFLibrary -lPocoNetd -lPocoUtild -lPocoFoundationd

当应用程序运行时，boost :: thread通常无法创建 .

第二次，我使用posix线程并构建应用程序，如下所示：

g -pthreads -lsocket -lnsl -o dist / Debug / GNU-Solaris-Sparc / accagent build / Debug / GNU-Solaris-Sparc / PassengerFlowThread.o build / Debug / GNU-Solaris-Sparc / AccDataTaker.o build / Debug /GNU-Solaris-Sparc/AccCache.o build / Debug / GNU-Solaris-Sparc / Acc.o build / Debug / GNU-Solaris-Sparc / DeviceStatusThread.o build / Debug / GNU-Solaris-Sparc / EntityAccessFactory.o build /Debug/GNU-Solaris-Sparc/BasicSmith.o build / Debug / GNU-Solaris-Sparc / CBThread.o build / Debug / GNU-Solaris-Sparc / SegmentedDeviceStatus.o build / Debug / GNU-Solaris-Sparc / AccInfo . pb.o build / Debug / GNU-Solaris-Sparc / CBException.o build / Debug / GNU-Solaris-Sparc / TimerThread.o build / Debug / GNU-Solaris-Sparc / STEModbusRequest.o build / Debug / GNU-Solaris- Sparc / SegmentedPassengerFlow.o build / Debug / GNU-Solaris-Sparc / ModbusConfigMap.o build / Debug / GNU-Solaris-Sparc / DeviceStatusSmith.o build / Debug / GNU-Solaris-Sparc / StationModeThread.o build / Debug / GNU- Solaris-Sparc / AccMain.o build / Debug / GNU-Solaris-Sparc / ModbusTcpServer.o build / Debug / GNU-Solaris-Sparc / PassengerFlo wSmith.o build / Debug / GNU-Solaris-Sparc / CacheKeeper.o build / Debug / GNU-Solaris-Sparc / SegmentedStationMode.o build / Debug / GNU-Solaris-Sparc / AccInfoImpl.o build / Debug / GNU-Solaris- Sparc / AsioClient.o build / Debug / GNU-Solaris-Sparc / AccDataSenderThread.o build / Debug / GNU-Solaris-Sparc / ModbusRequest.o build / Debug / GNU-Solaris-Sparc / AccDataSender.o build / Debug / GNU- Solaris-Sparc / StationModeSmith.o build / Debug / GNU-Solaris-Sparc / AccDataSenderTcpServer.o build / Debug / GNU-Solaris-Sparc / ModbusException.o build / Debug / GNU-Solaris-Sparc / CacheImpl.o build / Debug / GNU-Solaris-Sparc / EventManagerThread.o build / Debug / GNU-Solaris-Sparc / CacheKeeperThread.o build / Debug / GNU-Solaris-Sparc / log.o build / Debug / GNU-Solaris-Sparc / AccAgent.o -L ../../../cots/poco_1_4_6/lib/SunOS/sun4v -L ../../../ cots / protobuf_2_4_1 / src / .libs -L ../../../ cots / boost_1_55_0 / stage / lib -L ../../../ tools / lib -L ../../../ cots / oracle / 1120 / solaris10_sparc / lib -L ../../../ sdk -L ../../../ cots / RCF_2_0_0_2670 / library -lposix4 -lboost_program_options -lboost_syst EM-lboost_filesystem -lboost_thread -lclntsh -lprotobuf -lRCFLibrary -lPocoNetd -lPocoUtild -lPocoFoundationd

应用程序有时会转储以下信息：

程序终止，信号11，分段故障 . [新工艺735251] [新工艺800787] [新工艺866323] [新工艺931859] [新工艺997395] [新工艺79891] [新工艺407571] [新工艺538643] [新工艺604179] [新工艺669715]来自/usr/lib/ld.so.1的elf_find_sym（）中的0 0xfdbbe7fc

第三次，我也使用posix线程并使用follow（add -lpthread）构建：

g -lpthread -pthreads -lsocket -lnsl -o dist / Debug / GNU-Solaris-Sparc / accagent build / Debug / GNU-Solaris-Sparc / PassengerFlowThread.o build / Debug / GNU-Solaris-Sparc / AccDataTaker.o build /Debug/GNU-Solaris-Sparc/AccCache.o build / Debug / GNU-Solaris-Sparc / Acc.o build / Debug / GNU-Solaris-Sparc / DeviceStatusThread.o build / Debug / GNU-Solaris-Sparc / EntityAccessFactory . o build / Debug / GNU-Solaris-Sparc / BasicSmith.o build / Debug / GNU-Solaris-Sparc / CBThread.o build / Debug / GNU-Solaris-Sparc / SegmentedDeviceStatus.o build / Debug / GNU-Solaris-Sparc / AccInfo.pb.o build / Debug / GNU-Solaris-Sparc / CBException.o build / Debug / GNU-Solaris-Sparc / TimerThread.o build / Debug / GNU-Solaris-Sparc / STEModbusRequest.o build / Debug / GNU- Solaris-Sparc / SegmentedPassengerFlow.o build / Debug / GNU-Solaris-Sparc / ModbusConfigMap.o build / Debug / GNU-Solaris-Sparc / DeviceStatusSmith.o build / Debug / GNU-Solaris-Sparc / StationModeThread.o build / Debug / GNU-Solaris-Sparc / AccMain.o build / Debug / GNU-Solaris-Sparc / ModbusTcpServer.o build / Debug / GNU-Solaris-Sparc / Pa ssengerFlowSmith.o build / Debug / GNU-Solaris-Sparc / CacheKeeper.o build / Debug / GNU-Solaris-Sparc / SegmentedStationMode.o build / Debug / GNU-Solaris-Sparc / AccInfoImpl.o build / Debug / GNU-Solaris- Sparc / AsioClient.o build / Debug / GNU-Solaris-Sparc / AccDataSenderThread.o build / Debug / GNU-Solaris-Sparc / ModbusRequest.o build / Debug / GNU-Solaris-Sparc / AccDataSender.o build / Debug / GNU- Solaris-Sparc / StationModeSmith.o build / Debug / GNU-Solaris-Sparc / AccDataSenderTcpServer.o build / Debug / GNU-Solaris-Sparc / ModbusException.o build / Debug / GNU-Solaris-Sparc / CacheImpl.o build / Debug / GNU-Solaris-Sparc / EventManagerThread.o build / Debug / GNU-Solaris-Sparc / CacheKeeperThread.o build / Debug / GNU-Solaris-Sparc / log.o build / Debug / GNU-Solaris-Sparc / AccAgent.o -L ../../../cots/poco_1_4_6/lib/SunOS/sun4v -L ../../../ cots / protobuf_2_4_1 / src / .libs -L ../../../ cots / boost_1_55_0 / stage / lib -L ../../../ tools / lib -L ../../../ cots / oracle / 1120 / solaris10_sparc / lib -L ../../../ sdk -L ../../../ cots / RCF_2_0_0_2670 / library -lposix4 -lboost_program_options -l boost_system -lboost_filesystem -lboost_thread -lclntsh -lprotobuf -lRCFLibrary -lPocoNetd -lPocoUtild -lPocoFoundationd

现在该应用程序运行大约一天没有崩溃和任何其他异常 .

我的问题是：

1）-lpthread和-pthreads有什么区别？

2）“/usr/lib/ld.so.1”会影响我的应用吗？

3）我用-lpthread和-pthreads链接解决了这个问题吗？

顺便说一句，没有-pthreads，我的应用程序无法通过构建 .
