tell you if the DLL really exports that function. –Baffe Boyois Oct 7 '11 at 3:33 add a comment| 2 Answers 2 active oldest votes up vote 4 down vote accepted According to this discussion thread, some versions of libvorbisfile.dll are missing ov_fopen. share|improve this answer answered Oct 7 '11 at 3:39 Raymond Chen 35k65789 I don't know where you found that thread but that seems to be the case here. I opened the dll in depends and the function is missing! :( –user974967 Oct 7 '11 at 3:48 6 All I did was a web search for 'ov_fopen libvorbisfile' and boom there it was on the first page of results. –Raymond Chen Oct 7 '11 at 4:23 add a comment| up vote 3 down vote Examine the DLL with Depends and find out why you can't find the function. It's probably either just the name is wrong in the documentation or there's a name mangling issue. share|improve this answer answered Oct 7 '11 at 3:32 Carey Gregory 5,78121737 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Email Post as a guest Name Email discard By posting your answer, you agree to the privacy policy and terms of service.

takes a minute: Sign up LoadLibrary() error code 127 up vote 10 down vote favorite 3 I'm having trouble with LoadLibrary() and getting an error that doesn't make sense to me: ::SetLastError(0); m_hDll = ::LoadLibrary(szName); if (m_hDll == NULL) // http://stackoverflow.com/questions/7682732/getprocaddress-error-127-error-proc-not-found Failure to load the DLL. { DWORD err = GetLastError(); } The error is 127 ("The specified procedure could not be found.") That doesn't make any sense to me on a call to LoadLibrary(). I haven't called GetProcaddress() yet. The DLL (and the application) are both compiled with VS++ 2005 SP1.

Should it fail ::LoadLibrary? –Janusz Lenar Mar 17 '10 at 17:21 If DllMain sets 'last error' as 127 and then returns FALSE, will 'last error' be overwritten by the system before returning from ::LoadLibrary? –Janusz Lenar Mar 17 '10 at 17:25 add a comment| 8 Answers 8 active oldest votes up vote 16 down vote Let's take this step by step: The error message means that the dll was found but a required function is missing. (Jitter is right.) This implies that you have the dll you need, but not the right version. (Davefiddes is right, although the problem can be any dll, not just the Microsoft runtime library. And, at least for major updates, Microsoft gives its runtime libraries different names, so in that case it wouldn't be an issue.) This doesn't make sense, because no function has been requested from the dll being loaded. (Adam is right.) Therefore, the missing function was expected to be found not in the dll which is being explicitly loaded by the LoadLibrary command, but in a dependent dll which is being implicitly loaded at the same time, because the first dll requires it. (Zebrabox was close.) A dependent dll is a dll that is "statically" linked to the library being explicitly loaded, via an import library, or .lib file, included on the linker step of the explicitly loaded dll.

I've a very basic problem; I'm new to Cobol: I'm just trying to learn it, and started few hours ago. Having no linux installation by now, I downloaded the mingw-installer version for windows. The first problem came as I had a MinGW getprocaddress error 127 installed; i tried to copy the default.conf to /MinGW/share/Open-COBOL/config/ and it worked. In the "samples" directory, after setting the path to %path%;C:\OpenCOBOL\bin\, I compiled the bintest program and ran it using: cobc bintest.cbl cobcrun bintest without problems; Then I created a new source: hello.cbl, copying the code from the cobol page of wikipedia: IDENTIFICATION DIVISION. PROGRAM-ID. HELLOWORLD. ENVIRONMENT DIVISION. CONFIGURATION SECTION. DATA DIVISION. PROCEDURE DIVISION. DISPLAY 'HELLO, WORLD.'. STOP RUN. I compiled it with: cobc hello.cbl, obtaining a hello.dll Then I tried to run it with: cobcrun hello getting the message: libcob: LoadLibrary/GetProcAddress error 127 I tried to set COB_LIBRARY_PATH to C:\OpenCOBOL\lib\;C:\OpenCOBOL\samples\ and COB_PRE_LOAD=libcob - following a suggestion found on the opencobol forum - but the problem remain. What should I do? thanks in advance!
