debugging

问题 When remote debugging using gdbserver, I'd like to get gdb to load some shared libraries of the programm being debugging from the local sysroot, but also allow download feature from gdbserver to load others, which are not present in the sysroot.

Example, if I set sysroot to target:/ to use remote files, everything will be downloaded: (gdb) set sysroot target:/ (gdb) run Starting program:

问题 OutputDebugString() is native ASCII, which means it convert the input Unicode string to local string before call the ASCII version OutputDebugStringA() . Is there any alternative to OutputDebugString() which supports Unicode? 回答1: OutputDebugStringW does internally call OutputDebugStringA , so Unicode characters that cannot be represented in the system code page will be replaced with ? . Oddly enough, the OUTPUT_DEBUG_STRING_INFO structure the debugger receives from the operating system to

问题 Tl;Dr My partner and I published a Google Sheets add-on that is "randomonly" throwing "You do not have access to perform that action" when opening a spreadsheet.
