The output of ldd (32Bit) in cygwin 1.7.22 is not as expected if a single
dependency cannot be found.
Correct output (all dependencies present):
$ ldd Qt5Core.dll
ntdll.dll => /cygdrive/c/Windows/SysWOW64/ntdll.dll (0x778b0000)
kernel32.dll => /cygdrive/c/Windows/syswow64/kernel32.dll (0x76eb0000)
KERNELBASE.dll => /cygdrive/c/Windows/syswow64/KERNELBASE.dll
(0x76be0000)
USER32.dll => /cygdrive/c/Windows/syswow64/USER32.dll (0x75110000)
GDI32.dll => /cygdrive/c/Windows/syswow64/GDI32.dll (0x75330000)
LPK.dll => /cygdrive/c/Windows/syswow64/LPK.dll (0x75100000)
USP10.dll => /cygdrive/c/Windows/syswow64/USP10.dll (0x753c0000)
msvcrt.dll => /cygdrive/c/Windows/syswow64/msvcrt.dll (0x76ca0000)
ADVAPI32.dll => /cygdrive/c/Windows/syswow64/ADVAPI32.dll (0x76900000)
sechost.dll => /cygdrive/c/Windows/SysWOW64/sechost.dll (0x75490000)
RPCRT4.dll => /cygdrive/c/Windows/syswow64/RPCRT4.dll (0x76520000)
SspiCli.dll => /cygdrive/c/Windows/syswow64/SspiCli.dll (0x74f90000)
CRYPTBASE.dll => /cygdrive/c/Windows/syswow64/CRYPTBASE.dll (0x74f80000)
ole32.dll => /cygdrive/c/Windows/syswow64/ole32.dll (0x76d50000)
WS2_32.dll => /cygdrive/c/Windows/syswow64/WS2_32.dll (0x76100000)
NSI.dll => /cygdrive/c/Windows/syswow64/NSI.dll (0x76c90000)
icuin51.dll => /home/user/Qt-5.1.0/x86/icuin51.dll (0x49e80000)
icuuc51.dll => /home/user/Qt-5.1.0/x86/icuuc51.dll (0x4a0f0000)
icudt51.dll => /home/user/Qt-5.1.0/x86/icudt51.dll (0x7b0000)
MSVCR100.dll => /cygdrive/c/Windows/system32/MSVCR100.dll (0x74200000)
MSVCP100.dll => /cygdrive/c/Windows/system32/MSVCP100.dll (0x742c0000)
IMM32.DLL => /cygdrive/c/Windows/system32/IMM32.DLL (0x750a0000)
MSCTF.dll => /cygdrive/c/Windows/syswow64/MSCTF.dll (0x76830000)
Questionable output (a single dependency, icuin51.dll, is missing):
$ ldd Qt5Core.dll
ntdll.dll => /cygdrive/c/Windows/SysWOW64/ntdll.dll (0x778b0000)
kernel32.dll => /cygdrive/c/Windows/syswow64/kernel32.dll (0x76eb0000)
KERNELBASE.dll => /cygdrive/c/Windows/syswow64/KERNELBASE.dll
(0x76be0000)
??? => ??? (0x66d10000)
??? => ??? (0x75110000)
??? => ??? (0x75330000)
??? => ??? (0x75100000)
??? => ??? (0x753c0000)
??? => ??? (0x76ca0000)
??? => ??? (0x76900000)
??? => ??? (0x75490000)

??? => ??? (0x76d50000)
??? => ??? (0x76100000)
??? => ??? (0x76c90000)
My intention was to find out the dependencies of Qt5Core.dll in order to
satisfy them. This seems not possible in Windows.
The Linux version of ldd in this case prints a line like the following:
icuin51.so => not found
It would be great if the Windows version of ldd could behave the same (or at
least similar).
