高低位的问题。
因为 512 的二进制是 0010 0000 0000

2 的二进制是 0010

在我修改 了
大小端转换后，

load_cursor_from_file: LoadCursorFromFile: bad cursor image width (-1) and height (-1)
load_cursor_from_file: LoadCursorFromFile: failed when loading cursor from /usr/local/share/minigui/res/cursor/d_arrow.cur

平台是 loongarch64

[maikebing]

mips64 的机子就没这问题

Please check the endianess.

重置了龙芯版的统信系统， 重新安装了所有环境， 编译并启动后提示

GUI>LFRDR: failed to initialize default renderer's private info.
KERNEL>InitGUI: failed to init LF Manager!
KERNEL>InitGUI: initialization failed; please check your MiniGUI configuration or resource.

然后在 src/gui/lf_manager.c:864 设置断点，
if (rdr->init && 0 != rdr->init (rdr)) {
(gdb) p rdr->init
$1 = (int (*)(PWERENDERER)) 0xfff7c09c78
(gdb) p rdr->init(rdr)
$2 = -1
即 rdr->init(rdr) 返回-1 .

尝试了， 如果 禁用掉 cursor 不编译， 则 会出现上面的问题， 如果启用 -cursor 则 会 依旧出现

load_cursor_from_file: LoadCursorFromFile: bad file type: 512
load_cursor_from_file: LoadCursorFromFile: failed when loading cursor from /usr/local/share/minigui/res/cursor/d_arrow.cur
KERNEL>InitGUI: Count not init mouse cursor!
KERNEL>InitGUI: initialization failed; please check your MiniGUI configuration or resource.

应该是缺少对龙芯架构的处理导致的，在 common.h 中增加 defined(__loongarch__) 即可。

相关修改已添加到 ref-5-0 分支，可以试试 rel-5-0 上的代码。

[maikebing]

好的， 我尝试一下。
