libxml++移出对glibmm等库的依赖

原始依赖关系

libxml++

|--libxml2

|--glibmm

|--libsigc++

|--glib2.0

|--libffi

libxml++主要是使用了glibmm的Glib::ustring和Glib::Threads::Mutex两个类

2.Glib::ustring::format()主要使用在int转换为string，所以可以用boost::lexical_cast<std::string>或者封装成对 itoa的调用都可以

3.Glib::Threads::Mutex 互斥锁，和boost::mutex功能一样；Glib::Threads::Mutex::Lock范围锁， 和boost::mutex::scoped_lock功能一样

使用boost好处在于boost::lexical_cast和boost::mutex都只要头文件就可以

新的依赖关系

libxml++

|--libxml2

|--boost::lexical_cast（头文件）

|--boost::mutex（头文件）

下面是修改好的库文件

libxml++-2.38.0-no-glibmm.txz

4.G_STRFUNC => __FUNCTION__

==========
使用方法
tar -xJvf libxml++-2.38.0-no-glibmm.txz
cd libxml++-2.38.0-no-glibmm
make
make install

===========================
修改步骤

下载原始的源文件及其相关依赖的库
libxml++-2.38.0.tar.gz

--- 1..编译源文件及其相关依赖的库文件，生成出Makefile

编辑Makefile去掉glibmm相关的 -I -L -l

--- 2. 行末的“”是连接符，将他们改为一行后请手动去掉 cd <path_to_libxml++-2.38.0> sed -i "s/glibmm/ustring.h/string>n#include <boost/lexical_cast.hpp/g" libxml++/exceptions/exception.h find libxml++ -name "*.h" -exec sed -i "s/glibmm/ustring.h/string/g" {} ; -exec sed -i "s/Glib::ustring::format/boost::lexical_cast<std::string>/g" {} ; -exec sed -i "s/Glib::ustring/std::string/g" {} ; -exec sed -i "s/.bytes(/.length(/g" {} ; -exec sed -i "s/glibmm/threads.h/boost/thread.hpp/g" {} ; -exec sed -i "s/Glib::Threads::Mutex::Lock/boost::mutex::scoped_lock/g" {} ; -exec sed -i "s/Glib::Threads::Mutex/boost::mutex/g" {} ; -exec sed -i "s/G_STRFUNC/__FUNCTION__/g" {} ; find libxml++ -name "*.cc" -exec sed -i "s/glibmm/ustring.h/string/g" {} ; -exec sed -i "s/Glib::ustring::format/boost::lexical_cast<std::string>/g" {} ; -exec sed -i "s/Glib::ustring/std::string/g" {} ; -exec sed -i "s/.bytes(/.length(/g" {} ; -exec sed -i "s/glibmm/threads.h/boost/thread.hpp/g" {} ; -exec sed -i "s/Glib::Threads::Mutex::Lock/boost::mutex::scoped_lock/g" {} ; -exec sed -i "s/Glib::Threads::Mutex/boost::mutex/g" {} ; -exec sed -i "s/G_STRFUNC/__FUNCTION__/g" {} ; --- 3.修改文件libxml++/schemabase.h ("-" delete,"+"insert) @@ -21,10 +21,7 @@ #include <libxml++/noncopyable.h> -namespace Glib -{ -class ustring; -} +#include <string> --- 4. 修改libxml++/parsers/parser.cc 文件里面的"Parser::initialize_context()" 函数("-" delete,"+"insert) void Parser::initialize_context() { - Glib::Threads::Mutex::Lock lock(extra_parser_data_mutex); +ExtraParserData extra_parser_data_; +{ + boost::mutex::scoped_lock lock(extra_parser_data_mutex); //Clear these temporary buffers: extra_parser_data[this].parser_error_.erase(); @@ -142,8 +144,9 @@ // Take a copy of the extra data,so we don't have to access // the extra_parser_data map more than necessary. - const ExtraParserData extra_parser_data_this = extra_parser_data[this]; - lock.release(); + extra_parser_data_ = extra_parser_data[this]; +} +const ExtraParserData& extra_parser_data_this = extra_parser_data_; //Disactivate any non-standards-compliant libxml1 features. //These are disactivated by default,but if we don't deactivate them for each context @@ -210,13 +213,13 @@ } }
