Solution: add -luuid to to the libs.

[https://etherpad.mozilla.org/QsktItkkSE](https://etherpad.mozilla.org/QsktItkkSE)  
I saw this page and do that.  
Then, I encounter same problem that was recorded in the page.  
Its solution is 'add -luuid to to the libs.'  
what’s that mean??? I can’t understand this sentence

If it’s the makefile, one of those "LDFLAGS += " lines needs to have -luuid added to the end of it. It would probably look like “LDFLAGS += -lSDL2\_ttf -lSDL2\_image -luuid” around line 338. SDL on Windows is expecting a library libuuid.a in the MinGW lib folder to be included.

Could I ask you a question?  
When I try to compile new experimental version of cataclysm, this error occurred  
How do I solve this error?

I think mingw.thread.h was written for older versions of MinGW, since you have 5.2.0 apparently, you should be able to comment out the include “mingw.thread.h” around lines 24-26 in sounds.cpp to make it work.

🙂 thank you so much  
your advice was a really big help.

According to [https://www.libsdl.org/projects/SDL\_mixer/](https://www.libsdl.org/projects/SDL_mixer/), you should have flac, libmikmod, libogg, libvorbis, and smpeg libraries somewhere on the MSYS2 system. You can modify the LDFLAGS thing again to add -lflac -lmikmod -logg -lvorbis -lsmpeg if those are the correct names. They may have been downloaded when you got SDL2 mixer, but they are not automatically added to the library search.

Finally, I completed compilation.

However, problems remain…  
Sound effect(menu selection) was working properly.  
By contrast, any music can’t play in cataclysm.(add wav, mp3, ogg … of course, i edit json file)

I hope it will be my last challenge ☹

Because you didn’t provide any more details, I have to ask:

The sound card is properly installed and other programs can produce sound?  
Have you checked the volume (in-game setting and of the sound card)?  
Can those audio files be played in other programs?

Most importantly: what does config/debug.log contain? And what exactly did you edit in which JSON file.

I’m guessing the extra sound libraries could be dynamically linked for SDL2 from seeing the “dynamic\_modplug.o” in your earlier logs, you may need to copy related DLLs that are in your MSYS2 installation to the folder where you built your Cataclysm.exe. There could be filenames like mikmod.dll, ogg.dll in a “bin” folder near where the library files were installed.
