cygwin + Apache "out of the box": dlopen: Win32 error 126

Fri Nov 29 17:35:00 GMT 2002

The problem with cygcheck was my brain, been working too long with hourse to 
go still. cygcheck is a windows app so it will not take posix paths. As you 
see from above use cygpath -w (thanks to Max Bowsher) to convert the path...

Here's my cygcheck output:

[root@webdev]:{385}:% cygcheck `cygpath -w /usr/lib/apache/libphp4.dll`
F:\Cygwin\lib\apache\libphp4.dll
  F:\Cygwin\bin\cygbz21.0.dll
    F:\Cygwin\bin\cygwin1.dll
      C:\WINNT\System32\KERNEL32.dll
        C:\WINNT\System32\NTDLL.DLL
  F:\Cygwin\bin\cygcrypto.dll
  F:\Cygwin\bin\cygintl-1.dll
  F:\Cygwin\bin\pq.dll
  F:\Cygwin\bin\cygxml2-2.dll
    F:\Cygwin\bin\cygz.dll
  F:\Cygwin\bin\cyghttpd.dll

Use -h to see help about each section

Do you have all of these dll's?
