交叉编译libACE
1. 下载
访问ACE的官网http://download.dre.vanderbilt.edu/
下载ACE.tar.gz2 ，链接http://download.dre.vanderbilt.edu/previous_versions/ACE-6.2.4.tar.bz2
关于需要使用的sunxi交叉编译器，见http://blog.csdn.net/sakaue/article/details/19403025
2. 准备
执行命令，设置ACE_ROOT环境变量
export ACE_ROOT=/home/sakaue/ace/ACE_wrappers cd ~/ACE_wrappers/ace/ cp ./config-linux.h ./config.h cd ../include/makeinclude/ ln -s ./platform_linux.GNU ./platform_macros.GNU
修改Makefile中的编译器为sunxi的arm-linux-gnueabihf-*，Vi打开 include/makeinclude/platform_g++_common.GNU，原文为：
ifeq ($(insure),1)
CC = insure
CXX = insure
else
ifneq ($(CROSS_COMPILE),)
CROSS-COMPILE = 1
# Build using the cross-tools
ifneq ($($CROSS_COMPILE_POSTFIX),)
CC = ${CROSS_COMPILE}gcc{$CROSS_COMPILE_POSTFIX}
CXX = ${CROSS_COMPILE}g++{$CROSS_COMPILE_POSTFIX}
AR = ${CROSS_COMPILE}ar{$CROSS_COMPILE_POSTFIX}
else
CC = ${CROSS_COMPILE}gcc
CXX = ${CROSS_COMPILE}g++
AR = ${CROSS_COMPILE}ar
endif
# Cross-linker requires this for linked in shared libs that depend
# themselves on other shared libs (not directly linked in)
LDFLAGS += -Wl,-rpath-link,$(ACE_ROOT)/lib
ifneq (,$(HOST_ROOT))
TAO_IDLFLAGS += -g $(HOST_ROOT)/bin/ace_gperf
TAO_IDL = $(HOST_ROOT)/bin/tao_idl
TAO_IDL_DEP = $(TAO_IDL)
TAO_IDL3_TO_IDL2 = $(HOST_ROOT)/bin/tao_idl3_to_idl2
TAO_IDL3_TO_IDL2_DEP = $(TAO_IDL3_TO_IDL2)
TAO_IDL3_TO_XMI = $(HOST_ROOT)/bin/tao_idl3_to_xmi
TAO_IDL3_TO_XMI_DEP = $(TAO_IDL3_TO_XMI)
# make sure to use the target compiler, not the cross-compiler
# as preprocessor for the cross-compiled idl tools
TAO_IDL_PREPROCESSOR = gcc
endif
endif
endif修改为
CROSS_COMPILE:=arm-linux-gnueabihf-
#ifeq ($(insure),1)
# CC = insure
# CXX = insure
#else
ifneq ($(CROSS_COMPILE),)
CROSS-COMPILE = 1
# Build using the cross-tools
ifneq ($($CROSS_COMPILE_POSTFIX),)
CC = ${CROSS_COMPILE}gcc{$CROSS_COMPILE_POSTFIX}
CXX = ${CROSS_COMPILE}g++{$CROSS_COMPILE_POSTFIX}
AR = ${CROSS_COMPILE}ar{$CROSS_COMPILE_POSTFIX}
else
CC = ${CROSS_COMPILE}gcc
CXX = ${CROSS_COMPILE}g++
AR = ${CROSS_COMPILE}ar
endif
# Cross-linker requires this for linked in shared libs that depend
# themselves on other shared libs (not directly linked in)
LDFLAGS += -Wl,-rpath-link,$(ACE_ROOT)/lib
ifneq (,$(HOST_ROOT))
TAO_IDLFLAGS += -g $(HOST_ROOT)/bin/ace_gperf
TAO_IDL = $(HOST_ROOT)/bin/tao_idl
TAO_IDL_DEP = $(TAO_IDL)
TAO_IDL3_TO_IDL2 = $(HOST_ROOT)/bin/tao_idl3_to_idl2
TAO_IDL3_TO_IDL2_DEP = $(TAO_IDL3_TO_IDL2)
TAO_IDL3_TO_XMI = $(HOST_ROOT)/bin/tao_idl3_to_xmi
TAO_IDL3_TO_XMI_DEP = $(TAO_IDL3_TO_XMI)
# make sure to use the target compiler, not the cross-compiler
# as preprocessor for the cross-compiled idl tools
TAO_IDL_PREPROCESSOR = gcc
endif
endif
#endif
3. 编译
执行make，编译了一阵后出现错误：
.shobj/MEM_Acceptor.o:(.rodata+0x0): multiple definition of `typeinfo name for ACE_Singleton<ACE_Based_Pointer_Repository, ACE_RW_Thread_Mutex>' .shobj/Based_Pointer_Repository.o:(.rodata+0x0): first defined here .shobj/MEM_Acceptor.o:(.data.rel.ro+0x0): multiple definition of `typeinfo for ACE_Singleton<ACE_Based_Pointer_Repository, ACE_RW_Thread_Mutex>' .shobj/Based_Pointer_Repository.o:(.data.rel.ro+0x0): first defined here .shobj/MEM_Connector.o:(.rodata+0x0): multiple definition of `typeinfo name for ACE_Singleton<ACE_Based_Pointer_Repository, ACE_RW_Thread_Mutex>' .shobj/Based_Pointer_Repository.o:(.rodata+0x0): first defined here .shobj/MEM_Connector.o:(.data.rel.ro+0x0): multiple definition of `typeinfo for ACE_Singleton<ACE_Based_Pointer_Repository, ACE_RW_Thread_Mutex>' .shobj/Based_Pointer_Repository.o:(.data.rel.ro+0x0): first defined here ...推测是ace/config-g++-common.h中的宏定义
ACE_EXPORT_SINGLETON_DECLARATION ACE_EXPORT_SINGLETON_DECLARE
造成的，修改ace/config.h，在其中增加
#define ACE_GCC_HAS_TEMPLATE_INSTANTIATION_VISIBILITY_ATTRS 1或者，在include/makeinclude/platform_macros.GNU中增加
no_hidden_visibility=1注意，该语句必须加在include $(ACE_ROOT)/include/makeinclude/platform_linux_common.GNU之前，如
# -*- Makefile -*- # $Id: platform_linux.GNU 97130 2013-05-13 17:36:26Z mesnier_p $ no_hidden_visibility=1 include $(ACE_ROOT)/include/makeinclude/platform_linux_common.GNU
执行
make clean makeOK，顺利通过
