ProjectM notes

ProjectM notes:

Install JackOSX 0.90 beta 13 from:
http://www.jackosx.com
Install cmake using Homebrew
Download Qt from:
https://qt-project.org/downloads
I used Qt4 and compiled it statically from source. Static building isn't necessary but made it (in some ways) easier to make a self-contained application.
Download ProjectM source code from:
https://sourceforge.net/projects/projectm/files/2.1.0/projectM-complete-2.1.0-Source.tar.gz/download
cd into the top level directory of the unzipped source. Should contain playlists, presets, src, and other folders.
type 'ccmake .'

Use something similar to the following configuration:

and press 'c' to start configuring your build.

It can break at this stage if necessary software doesn't exist or can't be found on your system. Just make sure you have everything it asks for and be very explicit about where it is located. 

If configuring succeeds, you must press 'g' to generate a bunch of makefiles. This usually won't fail.

When this is over, type make to begin the building process. There are a ton of things that can go wrong here. I've made notes of the most common and frustrating issues that I ran into, and included solutions so you won't have to spend all the hours researching them that I did!


--------------------------------------------------------------------------------

To fix:
  Undefined symbols for architecture x86_64:
  "_kCFAllocatorDefault", referenced from:
Add:
  "-framework CoreFoundation -framework CoreVideo -framework VideoDecodeAcceleration" to the linker command line options.

--------------------------------------------------------------------------------

To fix:
	Linking CXX executable /Users/dominick/code/spotify/visualizer/build/bin/projectM-jack
	Undefined symbols for architecture x86_64:
	  "_main", referenced from:
	      start in crt1.10.6.o
	     (maybe you meant: _SDL_main)

Install SDL via brew `brew install sdl` and use `sdl-config --cflags --libs`  to locate SDL libraries for linking projectm-jack and presets
Add:
  "-I/usr/local/include/SDL -D_GNU_SOURCE=1 -D_THREAD_SAFE -L/usr/local/lib -lSDLmain -lSDL -Wl,-framework,Cocoa" to linker

--------------------------------------------------------------------------------

To fix:
Linking CXX executable /Users/dominick/code/spotify/visualizer/build/bin/projectM-jack
Undefined symbols for architecture x86_64:
  "_glShadeModel", referenced from:
      setup_opengl(int, int)in video_init.o

Add:
	"-framework OpenGL" to linker

--------------------------------------------------------------------------------

To fix mkdir error:
add <sys/stat.h>

--------------------------------------------------------------------------------

When building with tests, add
#include </Users/dominick/code/spotify/visualizer/projectM-SLIM/src/macos/FTGL/unix/GL/gl.h>
#include </Developer/SDKs/MacOSX10.7.sdk/System/Library/Frameworks/OpenGL.framework/Versions/A/Headers/glu.h>
to projectM-test.cpp

--------------------------------------------------------------------------------

To build with jack and Qt and prevent:
make[2]: *** No rule to make target `/projectM-engine/libprojectM.a', needed by `/Users/dominick/projectM-jack-qt-static/projectM-jack'.  Stop.

Solution: 
Open:
/Users/dominick/code/spotify/visualizer/projectM-SLIM/src/projectM-jack/CMakeFiles/projectM-jack.dir/build.make

and replace 
#/Users/dominick/projectM-jack-qt-static/projectM-jack: /projectM-engine/libprojectM.a
#/Users/dominick/projectM-jack-qt-static/projectM-jack: /projectM-qt/libprojectM-qt.a
with:
/Users/dominick/projectM-jack-qt-static/projectM-jack: /Users/dominick/projectM-jack-qt-static/libprojectM.a
/Users/dominick/projectM-jack-qt-static/projectM-jack: /Users/dominick/projectM-jack-qt-static/libprojectM-qt.a

then open:
/Users/dominick/code/spotify/visualizer/projectM-SLIM/src/projectM-jack/CMakeFiles/projectM-jack.dir/link.txt

and replace 
/projectM-engine/libprojectM.a 
with
/Users/dominick/projectM-jack-qt-static/libprojectM.a

and replace
/projectM-qt/libprojectM-qt.a
with
/Users/dominick/projectM-jack-qt-static/libprojectM-qt.a

--------------------------------------------------------------------------------

If a library is not found, i.e.:
Linking CXX shared library /Users/dominick/projectM-jack-qt-static/libprojectM-qt.dylib
ld: library not found for -lGLEW
collect2: ld returned 1 exit status

Then change /usr/lib/libGLEW.1.9.0.dylib to -L/Developer/SDKs/MacOSX10.7.sdk/usr/lib/libGLEW.1.9.0.dylib

--------------------------------------------------------------------------------

If the linker complains about the GL library:
Linking CXX shared library /Users/dominick/projectM-jack-qt-static/libprojectM-qt.dylib
ld: library not found for -lGL
collect2: ld returned 1 exit status

Delete '-lGL' from the link.txt and make sure '-framework OpenGL' is present

--------------------------------------------------------------------------------

When building with Qt static:

link.txt for projectm-jack:

you might need to build zlib?

--------------------------------------------------------------------------------

Use FULL PATHS for images in qplaylistmodel.cpp and  ui_qprojectm_mainwindow.h to get icons to appear!!!
ui_qprojectm_mainwindow.h can be overwritten during a build
