Hello,
I'm trying to compile vlc in a mingw/msys environment but keep getting the error below. I followed all the steps in the https://wiki.videolan.org/Win32CompileMSYSNew/ wiki and also looked at the trouble shooting guide but could not get a solution. Any help on how to proceed would be appreciated. Thanks.

Hi. I got this same error as well. I skipped the zvbi module and got much further, but not after several workarounds.

I detail more below. For any of the developers, my summarized list of questions is as follows:

is the m4 workaround below correct?
is libpthreadGC2.a broken, or if there is another way to build libzvbi?
is the libFLAC workaround correct?
what is the correct fix for direct2d.c and IID_ID2D1Factory?
what is the correct fix for events.c and tolower?
what is the fix for ole2.h?
why did the process stop after making the vlc-2.2.0-git directory?

Background
First, for reference's sake, I used the walkthrough here: https://wiki.videolan.org/Win32CompileMSYS/ (which includes the prebuilt msys). I only deviated from the walkthrough in each of the sections listed below.

Also, I'm trying this on a new Windows 7 64-bit system. I chose the 32 bit version for TDM/MinGW (since 64 bit was marked experimental).

config tools and m4 error
I got the error "configure: error: no acceptable m4 could be found in $PATH." I found this thread here: https://forum.videolan.org/viewtopic.php?f=14&t=106503.

I resolved it by opening \vlc\extras\tools\packages.mak and changing AUTOCONF_VERSION=2.69 -> AUTOCONF_VERSION=2.67

zvbi and WSAGetLastError
I then got the WSAGetLastError during the zvbi process

I tried various things with zvbi to work around the WSAGetLastError. However, my limited understanding is that there is something wrong with the pre-built contrib: libpthreadGC2.a. Here is my reasoning:

WSAGetLastError appears to be related to libws2_32.a
libws2_32.a is on my machine at C:\MinGW\lib\libws2_32.a
Meanwhile, the undefined reference error is coming from libpthreadGC2.a
As libpthreadGC2.a is a contrib binary, it is not configurable by the VLC build process
For good measure, I tried adding "-lws2_32" to libzvbi.la. Still the same error

I ended up disabling this module by adding "-disable-zvbi" to configure.

libFLAC: undefined reference to `ntohl@4'
After disabling libzvbli, I got this error:

`ntohl@4' is also related to the ws2_32 library. I fixed this by opening C:\MinGW\msys\home\gnosygnu\vlc\contrib\mingw32\lib\libFLAC.la and adding "-lws2_32"

I opened the file and commented out the line (which I understand will probably break direct2d, but I wanted to finish compiling)

I opened the file and declared the variable as a NULL (again, I just wanted to finish compiling)

error: required OLE header ole2.h is missing from your system
Compiling finally completed. However, the package making failed with the ole2.h error.

I found this thread (https://forum.videolan.org/viewtopic.php?f=14&t=111646) and checked my config.log file in napi-vlc. The relevant excerpt is below

I looked up the error: unrecognized command line option '-static-libstdc++' and found this thread: http://stackoverflow.com/questions/1422 ... ingw-4-7-1

This seems to indicate that I should be using TDM/MinGW 4.7.1, not 4.6.3. However the walkthrough explicitly crosses out 4.7.1 and directs to 4.6.3. Should 4.7.1 not be used?

On a wild guess, I then searched for '-static-libstdc++' in all files, and replaced it with "-static -lstdc++ -dynamic".

Surprisingly, this worked. The process continued and even generated the vlc-2.2.0-git directory, until...

At which point, I gave up. It was late. There were no error messages on screen for the activex build, but the file was clearly not there.
