Use the "info sharedlibrary" command to see the complete listing. Do you need "set solib-search-path" or "set sysroot"? (gdb) info sharedlibrary >From To Syms Read Shared Object Library No C:\Windows\system32\ntdll.dll No C:\Windows\syswow64\kernel32.dll No C:\Windows\syswow64\KernelBase.dll No C:\Windows\syswow64\msvcrt.dll No D:\mingw.tests\d.dll setting solib-search-path fixes the issue.
