D2和gdb问题
简短的问题:在gdb中是否支持D2(我有gdb 7.2)?
长话短说:我编了下一个小应用程序......
// file main.d
int glVar = 0xAAAAAAAA;
void main()
{
glVar = 0xBBBBBBBB;
}
...使用命令“dmd -gc -debug main.d”;
然后我将它加载到gdb并尝试调试它:
vnm@vnm:~/proj/d_gdb_test$ gdb main GNU gdb (GDB) 7.2-ubuntu Copyright (C) 2010 Free Software Foundation, Inc.

(gdb) info variables glVar All variables matching regular expression "glVar": File main.d: int _D4main5glVari;
为什么gdb无法显示行信息,以及为什么它显示符号格式错误? 这是软件问题还是我做错了什么?
gdb支持D从7.2开始。 所以,你可以用gdb 7.2来调试D程序。
现在,这并不意味着支持是完美的 - 事实上远非如此。 例如,我不确定你能否正确打印字符串。 如果它不去除D符号,这并不令人意外。 所以,它有效,但它远非完美。
