need help on compile error caused by one of the contribs

[eddiek]

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...

cannot stat `axvlc.dll'

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.
