在Solaris 10 x86下用gcc编译Poco 1.4.6

一、 系统环境

操作系统原始环境如下：

$ uname -a 

SunOS sol10u6 5.10 Generic_137138-09 i86pc i386 i86pc

$ /usr/sfw/bin/gcc -v

Reading specs from /usr/sfw/lib/gcc/i386-pc-solaris2.10/3.4.3/specs

Configured with: /builds/sfw10-gate/usr/src/cmd/gcc/gcc-3.4.3/configure --prefix=/usr/sfw --with-as=/usr/sfw/bin/gas --with-gnu-as --with-ld=/usr/ccs/bin/ld --without-gnu-ld --enable-languages=c,c++ --enable-shared

Thread model: posix

gcc version 3.4.3 (csl-sol210-3_4-branch+sol_rpath)

$ /usr/ccs/bin/ld -V

ld: Software Generation Utilities - Solaris Link Editors: 5.10-1.490

$ gmake --version

二、 安装补丁包

Solaris 10 x86自带的gcc版本为3,4.3，指定链接器为/usr/ccs/bin/ld，但是在poco对应gcc编译器的配置文件build/config/SunOS-GCC中，指定的链接器参数是GNU ld格式的，编译时会报出许多跟链接器有关的警告及错误，所以，必须强制gcc使用GNU ld。我不知道gcc是不是可以通过命令行参数来指定所使用的链接器，我是通过重命名系统自带的/usr/ccs/bin/ld文件，然后在/usr/ccs/bin/下建立一个符号连接，指向GNU ld来达到这一目的的。

系统自带的GNU ld版本为2.15，此版本的GNU ld有一个bug，在Solaris 10中，将许多在Solaris 9中原本处于.bbs段的符号移到了.abs段，而GNU ld不会处理.abs中导出的符号，导致在链接时报许多符号找不到的错误。在GNU binutils 2006年的bug邮件列表里详细讨论了此问题及解决方法。我不太确定GNU ld具体是在哪一个版本里修正了此bug，我下载的2.21.1版本的binutil二进制包中已经修正了此bug。binutils依赖于以下的包：libiconv，libintl，zlib，libgcc-3.4.6或者c-3.4.6。必须安装这些包才能顺利编译poco，各个包安装的先后次序没有要求。安装完各个包之后，先将系统自带的/usr/ccs/bin/ld重命名，然后ln -s /usr/local/bin/ld  ld建议一个符号连接。

通过命令pkgadd -d filename安装以下包：

binutils-2.21.1a-sol10-x86-local

gcc-3.4.6-sol10-x86-local

libiconv-1.14-sol10-x86-local

libintl-3.4.0-sol10-x86-local

zlib-1.2.7-sol10-x86-local

安装完成后环境如下：

$ which gcc

/usr/local/bin/gcc

$ /usr/local/bin/gcc -v

Reading specs from /usr/local/lib/gcc/i386-pc-solaris2.10/3.4.6/specs

Configured with: ../configure --with-as=/usr/ccs/bin/as --with-ld=/usr/ccs/bin/ld --enable-shared --enable-languages=c,c++,f77

Thread model: posix

gcc version 3.4.6

$ ls -l /usr/ccs/bin/ld

$ /usr/local/bin/ld --version

三、 修改poco配置文件

1.编辑build/config/SunOS-GCC文件，找到以下行：

#

# System Specific Libraries

#

SYSLIBS  = -lpthread -ldl -lrt

修改为：

#

# System Specific Libraries

#

SYSLIBS  = -lrt -lsocket -lnls

On S10 libpthread is an empty filter on libc, which is a fancy way of saying that all of the code in libthread moved to libc and libpthread is just a shell saying as much so that older programs linked with libpthread can still run.

gld is choking on Solaris libraries that are filters.

2.编辑build/rules/global文件，找到以下行：

#

# Build Include directory List

#

INCLUDE = $(foreach p,$(POCO_ADD_INCLUDE),-I$(p)) -Iinclude $(foreach p,$(COMPONENTS),-I$(POCO_BASE)/$(p)/$(INCDIR))

#

# Build Library Directory List

#

LIBRARY = $(foreach p,$(POCO_ADD_LIBRARY),-L$(p)) -L$(LIBPATH:) $(POCO_LIBRARY)

修改为：

#

# Build Include directory List

#

INCLUDE = $(foreach p,$(POCO_ADD_INCLUDE),-I$(p)) -Iinclude -I/usr/sfw/include -

I/usr/sfw/include/mysql $(foreach p,$(COMPONENTS),-I$(POCO_BASE)/$(p)/$(INCDIR))

#

# Build Library Directory List

#

LIBRARY = $(foreach p,$(POCO_ADD_LIBRARY),-L$(p)) -L/usr/sfw/lib -L$(LIBPATH) $(

POCO_LIBRARY)

======

3.运行configure生成配置文件：

$ ./configure --prefix=$HOME/poco --config=SunOS-GCC --omit=Data/ODBC,Data/MySQL
