所以我终于能够下载旧版本的webkit,并在终端中使用经典的编译它(在修复了100个错误之后)
./configure
make
现在,既然我有了程序的源代码,我的目标就是调试它(在C++代码和其他东西上设置断点)。由于我是第一次在这里使用Linux,所以我下载eclipse以获得直观的GUI。然而,当我导入项目时,我似乎无法编译它。Include错误无处不在,无论我怎么尝试都无法解决它们。
当我可以在终端中编译它时,我如何在eclipse中编译它?此外,是否有其他方法来调试程序?
非常感谢!
好的,所以我设法编译并链接了代码,这样它就可以用符号调试信息加载到gdb中,如下所示:
- 我下载并提取http://webkitgtk.org/releases/webkitgtk-2.0.4.tar.xz
- 我跑了/配置并手动执行
apt-get install
(或者在下载和编译ICU的情况下)所有所需的依赖关系 - 然后,我对
GNUmakefile
进行了以下修改,添加了-ggdb
到每个可用的global_cppflags
global_cflags
和global_cxxflags
(为了加快构建速度,我从cppflags中删除了所有警告标志,不确定它是否有区别。如果要针对此构建进行开发,可能应该恢复这些警告标志)
GNUmakefile
global_cppflags := -ggdb -fno-exceptions -DBUILDING_CAIRO__ -DBUILDING_GTK__
$(am__append_1) $(am__append_2)
#global_cppflags := -Wall -W -Wcast-align -Wchar-subscripts
# -Wreturn-type -Wformat -Wformat-security -Wno-format-y2k
# -Wundef -Wmissing-format-attribute -Wpointer-arith
# -Wwrite-strings -Wno-unused-parameter -Wno-parentheses
# -fno-exceptions -DBUILDING_CAIRO__ -DBUILDING_GTK__
# $(am__append_1) $(am__append_2)
global_cflags := -ggdb
global_cxxflags := -ggdb -fno-rtti
然后,为了测试调试符号是否包含在编译器和链接器输出中,我运行了如下的gdb
~/dev/webkitgtk-2.0.4$ gdb ./Programs/MiniBrowser -d ./Tools/MiniBrowser/gtk/
