Subject: cygcheck exit status
Date: Tue, 05 Jul 2005 19:25:04 +0000
Message-Id: <070520051925.9884.42CADE90000B336F0000269C22007348300A050E040D0C079D0A@comcast.net>

It is annoying that cygcheck exits with status 0, even if it could not find a file:

$ cygcheck /bin/lilypond.exe
C:/cygwin/bin/lilypond.exe
  C:/cygwin/bin\cygwin1.dll
    C:\WINNT\system32\ADVAPI32.DLL
      C:\WINNT\system32\NTDLL.DLL
      C:\WINNT\system32\KERNEL32.DLL
      C:\WINNT\system32\RPCRT4.DLL
  C:/cygwin/bin\cygguile-12.dll
    C:/cygwin/bin\cygcrypt-0.dll
    C:/cygwin/bin\cygguile-ltdl-1.dll
  C:/cygwin/bin\cygintl-3.dll
    C:/cygwin/bin\cygiconv-2.dll
Error: could not find cygkpathsea-4.dll
$ echo $?
0
$ cygcheck none
Error: could not find none
$ echo $?
0

This makes exit status worthless when trying to use cygcheck to verify if
an existing file has any broken dependencies (a la the bash upgrade
scenarios being discussed on cygwin-apps).  I tried to prepare a patch,
but returning EXIT_FAILURE from main() still produced a 0 exit status,
so it might be that the magic that makes cygcheck know about
cygwin1.dll while still being a Windows app needs fixing, too.
