将 libxml++ 和 glib 库与适用于 C++ Windows 的 CodeBlocks IDE 链接的问题

本文介绍了将 libxml++ 和 glib 库与适用于 C++ Windows 的 CodeBlocks IDE 链接的问题的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在使用 Code Blocks IDE 为 Windows 编写 C++ 应用程序.我有兴趣使用以下 XML++ 库:.我找不到 glibmm 的预构建 Windows 二进制文件，因此您要么必须下载整个 gtkmm 安装程序，或自己构建.

这个过程完成后，你应该有像这样的文件

libxml2.liblibxml2.alibxml2.dll

根据您的编译器(GCC 或 MSVC)以及所需的链接方法(静态或动态)，您应该选择所需的库文件.

在 Code::Blocks 中，您可以通过链接器设置"选项卡进行链接，可通过 Project -> 访问.构建选项... ->链接器设置.点击add，选择之前编译好的使用文件夹浏览器的库文件(libxml2、glibmm-2.4 和 libxml++).

更新:我能够在我的 Windows 8 64 位 PC 上成功运行该项目.

我从 MinGW-builds (GCC 4.8.1) 安装了 MinGW-64.我唯一需要下载的是 gtkmm-win64 安装程序.我选择了完整安装".

项目构建设置中的搜索目录为:

C:gtkmm64includeC:gtkmm64includelibxml++-2.6C:gtkmm64includeglibmm-2.4C:gtkmm64includeglib-2.0C:gtkmm64libglibmm-2.4includeC:gtkmm64libglib-2.0includeC:gtkmm64liblibxml++-2.6include

要链接的导入库是:

C:gtkmm64liblibxml++-2.6.dll.aC:gtkmm64liblibglibmm-2.4.dll.aC:gtkmm64liblibglibmm_generate_extra_defs-2.4.dll.a

DLL 从 gtkmm64in 文件夹复制到可执行文件的位置是:

libglib-2.0-0.dlllibglibmm-2.4-1.dlllibglibmm_generate_extra_defs-2.4-1.dlllibxml++-2.6-2.dlllibxml2-2.dll

可执行文件成功运行(不包括程序由于某些解析异常而终止的事实).

I am writing a C++ app for Windows using Code Blocks IDE. I am interested in using the following XML++ library: http://libxmlplusplus.sourceforge.net/

It requires libxml2 and glibmm-2.4 libraries. I downloaded the source for each of these libraries and included all of the headers into my project by right clicking on "Build Options" ==> "Search Directories" tab ==> "Compiler" tab. I specified the header include files there. I modified the main.cpp file using the source code from "examples/dom_parser" from the xml++/examples directory.

Now, I am having trouble with the following error message. I have never "linked" or used *.lib, *.dll files before... but I am now getting the following "undefined reference" error messages. Please let me know what I'd need to do in order to build this. Is there a particular file that I need to "link" and if so, where are these files located? I can't seem to find them in the source files that I extracted. Could you help with specific instructions on which files to include and which folders they might be located in? I am using the CodeBlocks IDE.

Could someone replicate the project on your Windows 64 bit PC and see if it is able to run correctly?

Thank you.

**UPDATED 02/11/2014 - at 10:45am **

Hi. Thanks for your suggestion. I ended up downloading the following ( http://ftp.gnome.org/pub/gnome/binaries/win32/gtkmm/2.22/ ) the entire gtkmm-win32-devel-2.22.0-2.exe and installed it onto my Windows PC in C:gtkmm. Then, I modified my project by including the header files, library files, and bin files. Here are the screen shots:

After building, I am now seeing 0 errors and 0 warning messages. However, it appears to CRASH. I have no idea why. It seems that the gtk installation uses libxml++ version 2.6. This is fine. I downloaded the libxml++ 2.6 from the website to see the examples that they provided. I used the following source code in my main.cc. Do you know what is the problem?

Are libxml2 and glibmm-2.4 built?

You can find prebuilt windows binaries for libxml2 here. I can't find prebuilt windows binaries for glibmm, so you'll either have to download the entire gtkmm installer, or build it yourself.

After this process is done, you should have files such as

libxml2.lib
libxml2.a
libxml2.dll

Depending on you compiler (GCC or MSVC), and the desired linking method (static or dynamic), you should choose the required library files.

In Code::Blocks you do the linking via the "Linker settings" tab, accessible through Project -> Build options... -> Linker settings. Click add and select the previously compiled library files (libxml2, glibmm-2.4 and libxml++) using the folder browser.

Update: I am able to successfully run the project on my Windows 8 64-bit PC.

I have a MinGW-64 installation from MinGW-builds (GCC 4.8.1). The only other thing I had to download was the gtkmm-win64 installer. I chose the "full installation".

The search directories in the project build settings were:

C:gtkmm64include
C:gtkmm64includelibxml++-2.6
C:gtkmm64includeglibmm-2.4
C:gtkmm64includeglib-2.0
C:gtkmm64libglibmm-2.4include
C:gtkmm64libglib-2.0include
C:gtkmm64liblibxml++-2.6include

The import libraries to link to were:

C:gtkmm64liblibxml++-2.6.dll.a
C:gtkmm64liblibglibmm-2.4.dll.a
C:gtkmm64liblibglibmm_generate_extra_defs-2.4.dll.a

And the DLL's copied to the executable's location from the gtkmm64in folder were:

libglib-2.0-0.dll
libglibmm-2.4-1.dll
libglibmm_generate_extra_defs-2.4-1.dll
libxml++-2.6-2.dll
libxml2-2.dll

The executable ran successfully (excluding the fact that the program terminated due to some parsing exception).
