在Solaris 10 x86下用gcc編譯Poco 1.4.6

一、 系統(tǒng)環(huán)境

操作系統(tǒng)原始環(huán)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

二、 安裝補(bǔ)丁包

Solaris 10 x86自帶的gcc版本為3,4.3，指定鏈接器為/usr/ccs/bin/ld，但是在poco對應(yīng)gcc編譯器的配置文件build/config/SunOS-GCC中，指定的鏈接器參數(shù)是GNU ld格式的，編譯時會報出許多跟鏈接器有關(guān)的警告及錯誤，所以，必須強(qiáng)制gcc使用GNU ld。我不知道gcc是不是可以通過命令行參數(shù)來指定所使用的鏈接器，我是通過重命名系統(tǒng)自帶的/usr/ccs/bin/ld文件，然后在/usr/ccs/bin/下建立一個符號連接，指向GNU ld來達(dá)到這一目的的。

系統(tǒng)自帶的GNU ld版本為2.15，此版本的GNU ld有一個bug，在Solaris 10中，將許多在Solaris 9中原本處于.bbs段的符號移到了.abs段，而GNU ld不會處理.abs中導(dǎo)出的符號，導(dǎo)致在鏈接時報許多符號找不到的錯誤。在GNU binutils 2006年的bug郵件列表里詳細(xì)討論了此問題及解決方法。我不太確定GNU ld具體是在哪一個版本里修正了此bug，我下載的2.21.1版本的binutil二進(jìn)制包中已經(jīng)修正了此bug。binutils依賴于以下的包：libiconv，libintl，zlib，libgcc-3.4.6或者c-3.4.6。必須安裝這些包才能順利編譯poco，各個包安裝的先后次序沒有要求。安裝完各個包之后，先將系統(tǒng)自帶的/usr/ccs/bin/ld重命名，然后ln -s /usr/local/bin/ld  ld建議一個符號連接。

www.sourceware.org/bugzilla/show_bug.cgi?id=1021

通過命令pkgadd -d filename安裝以下包：

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

安裝完成后環(huán)境如下：

$ which gcc

$ /usr/local/bin/gcc -v

三、 修改poco配置文件

1.編輯build/config/SunOS-GCC文件，找到以下行：

#

# System Specific Libraries

#

SYSLIBS  = -lpthread -ldl -lrt

修改為：

#

# 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.編輯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)

修改為：

#

# 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.運(yùn)行configure生成配置文件：

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

Configured for SunOS-GCC
