Win: Missing DLLs in dynamic build

[Tomasito665]

It looks like the Windows buildserver is not working properly for dynamic builds. Various dependencies are built in static mode, even though build_environment.bat is given the Dynamic argument. This results in unmet dependencies when compiling Mixxx.

This is my build.bat script for Mixxx: https://pastebin.com/cd1bctuX And this is the output: https://pastebin.com/RABLSfCY

I ran build_environment.bat x64 ReleaseFastbuild Dynamic, which fails to build dynamic libraries for:

• libid3tag
• libmad
• libopus
• libshout
• libsndfile
• portaudio
• portmidi (porttime)
• protobuf
• pthreads
• rubberband
• sqlite3
• taglib

For completeness, these are the output files in buildserver/lib per dependency.

*(!)  = Static version of library built instead of shared one.

Some of this is actually expected. Certain libraries only have static build configurations (like porttime) and others wouldn't link with Mixxx if built dynamically, so the "Dynamic" flag simply builds what it can dynamically as opposed to everything. As for taglib not producing anything, that's unexpected.

[Pegasus-RPG]

It's also possible some of the batch files are not correctly reading the flag. :)

@Pegasus-RPG Ah, that explains a lot :-) Still though, many of the batch files of the (!) annotated libs expect a DLL, in the sense that there is a copy *.dll %LIB_DIR% command when done compiling. This is true for these libs:

• opus.dll
• opusfile.dll
• libshout.dll
• libsndfile.dll
• portaudio.dll
• portmidi.dll
• porttime.dll
• libprotobuf-lite.dll
• pthread.dll
• rubberband.dll
• sqlite3.dll
• tag.dll

I think that's the case with taglib. I made a small tweak, which solves the problem for me: https://github.com/Tomasito665/buildserver/commit/34aa86e4c193cd05695eb23df5a33820d215b857

... I have a vague memory of doing that by default, instead of only copying if we know it was going to produce a DLL.

@Pegasus-RPG My bad! Taglib does produce something. The list is updated.

[Tomasito665]

Hmm.. I just rebuilt all dependencies from scratch with build_environment.bat x64 ReleaseFastbuild Dynamic. There aren't any unmet dependencies now. Everything seems to compile fine, but I get unresolved external symbol errors from the linker.

Here's the full log: https://pastebin.com/DxdJUsVD Any idea of what the cause could be?

scons: building terminated because of errors.

[Pegasus-RPG]

The __declspec dllimport stuff usually means a dynamic library is trying to be linked statically or vice-versa, I forget exactly. (If you built dynamic dependencies, are you also building Mixxx dynamically?) Otherwise, troubleshooting this takes a lot of trial and error.

[Pegasus-RPG]

Oh, that output may just be for mixxx-test.exe. Do you see mixxx.exe in the build folder?

[Tomasito665]

When building Mixxx I set both staticlibs and staticqt to false. This is my build batch script:

@echo off
SETLOCAL
REM Clean up after old builds.
del /q /f *.exe
rmdir /s /q dist32
rmdir /s /q dist64

REM XP Compatibility requires the v7.1A SDK

ENDLOCAL

There's no mixxx.exe in the build directory. I think the build fails before building that.

[Tomasito665]

Oh and I also tried to build just mixxx.exe by setting test=0. This is the output:

[Tomasito665]

It looks like these functions:

• __imp_RegCloseKey
• __imp_RegQueryValueExW
• __imp_GetDesktopWindow
• __imp_CharLowerBuffA
• __imp_RegEnumKeyA
• etc ...

are defined in the Windows libraries User32 and Advapi32. These are only added by scons when the static_qt is false, here: https://github.com/mixxxdj/mixxx/blob/master/build/depends.py#L373

@rryan is that correct? Shouldn't these libs be always added, both for static_qt and non-static_qt builds?

[Pegasus-RPG]

It looks like the Scons script needs to be adjusted to add those as dependencies for Portaudio as well.

[Tomasito665]

I could take this up, if that's useful? As soon as everything's working I could do two PRs, one for the buildserver and one for Mixxx.

[Pegasus-RPG]

Sure, if you're willing, that would save us a bunch of time. FYI, we found that adding advapi32 and user32 are only needed for static builds. There are already sections in our Scons scripts for each dependency where there's an if static block that adds whatever extra libraries are needed for that particular library to the linker list, so you should just need to extend that. (What's strange is that you shouldn't need to do that for a dynamic build, so again I wonder if flags are being passed correctly.) If you're switching flags, you may need to delete your .sconsign.dblite and .sconf.temp files to clear Scons' configuration and start fresh. (It's possible previous flags are still hanging around.)

[Tomasito665]

Ok I made some progress. I got Mixxx to compile in dynamic mode, but it crashes on startup (also with the safeMode flag). This is what I found so far.

Protobuf

The buildserver only builds the protobuf library in static mode but yet depends.py expects the dynamic version given not static_dependencies and adds the PROTOBUF_USE_DLLS preprocessor definition. This causes the unresolved external symbol "__declspec(dllimport ... errors.

We can solve this by either building both static and dynamic versions of protobuf or by removing the preprocessor definition from the scons script.

Portaudio

The buildserver only builds the portaudio library in static mode but yet depends.py expects the dynamic version given not static_dependencies. It only links to advapi32 in static dependencies mode, but it should always link to advapi32, because portaudio is always static. This causes the unresolved external symbol errors.

Also, portaudio needs both advapi32 and user32, but yet the portaudio dependence block only adds advapi32. In static_dependencies mode this is not a problem because it's already added by the Qt dependence block, but I think it's better to explicitly add it to portaudio as well.

We can solve this by either building both static and dynamic versions of portaudio or by always doing the env.CheckLib for advapi32 and user32, regardless of static_dependencies.

Rubberband

This is a sneaky one. Rubberband depends on fftw, just like chromaprint. However, we only check for fftw in the chromaprint dependence block. Rubberband does not complain because fftw is already added here. The thing, though, is that chromaprint only adds fftw if static_dependencies and that's ok for chromaprint, but rubberband -- since we only build rubberband in static mode -- always needs fftw. So, when building in dynamic mode, fftw is not added and rubberband complains. So, we have to add the fftw check to the rubberband dependence block as well in the scons script.

What I did

I did three things to solve these problems and get Mixxx to compile.

• build both static and dynamic versions of protobuf
• build both static and dynamic versions of portaudio (moved to CMake, which provides configurations for both)
• edited the scons script (not yet on git)

Mixxx crashes on startup (progress bar hangs at about 30%). It looks like there are problems loading soundsourcemediafoundation. This is the console output.

Edit 1 It freezes during the call to m_pDbConnectionPool->createThreadLocalConnection();. Here, to be more precise.

Edit 2 I tested it both in debug and release with respectively Debug and DebugFastbuild dependencies. The problem happens with both builds.
