Building ZynAddSubFx: packages ntk / ntk_images not found
« on: November 22, 2014, 03:56:37 AM »
hi all :) (my first post here)

i'm trying to build zynaddsubfx from scratch. (zynaddsubfx 2.4.4 with mxml 2.5 - all other components from tc 5.x repo)
i got pretty far,  pretty much all dependencies met, and it kinda builds (cmake, make).
but what still seems to be missing is a GUI.

i have installed fltk, fltk-dev, and fluid
now when building zynaddsubfx with default config, it says (among other things):
-- Found FLTK: /usr/local/lib/libfltk_images.so;/usr/local/lib/libfltk_forms.so;/usr/local/lib/libfltk.so
-- -L/usr/local/lib -Wl,-rpath,/usr/local/lib -lfltk_images -lpng -lz -ljpeg -lfltk -lpthread -ldl -lm -lXext -lX11
-- Will build FLTK gui
-- using link directories: /usr/local/lib  /usr/local/lib /usr/local/lib
-- Link libraries: /usr/lib/libz.so  mxml /usr/local/lib/libasound.so;jack         <- fltk missing here?
...but compilations shows some errors, and linking fails with errors like this:
UI/libzynaddsubfx_gui.a(NioUI.cpp.o):(.data.rel.ro._ZTI5NioUI[_ZTI5NioUI]+0x8): undefined reference to `typeinfo for Fl_Window'

this, to me, looks like some lib or linker option is missing.
can someone point me to what I have to edit or add or change?


i also have installed ntk and ntk-dev (for alternative GUI)
but these are - weirdly - not found by zynaddsubfx.
all other packages I installed are found (jack, mxml, fftw3, ...)
at /usr/local/lib/pkgconfig (I assume) and there's also ntk.pc, ntk_gl.pc, ntk_images.pc there
but still zynaddsubfx complains
-- checking for module 'ntk'
--   package 'ntk' not found
-- checking for module 'ntk_images'
--   package 'ntk_images' not found
what really seems weird to me is that in zynaddsubfx/src/CMakeLists.txt I can see that checking for jack, mxml, ... is exactly the same function "pkg_check_modules" as checking for ntk and ntk_images:
   #Dependency check
   pkg_check_modules(MXML REQUIRED mxml)    <-  found
   pkg_check_modules(JACK jack)                       <- found
   pkg_check_modules(NTK ntk)                            <- not found
   pkg_check_modules(NTK_IMAGES ntk_images)         <- not found

any ideas why ntk and ntk_images cannot  be found?


thanks, regards,
Ro

You need to have -fno-rtti -fno-exceptions in your CXXFLAGS.
The only barriers that can stop you are the ones you create yourself.

hi,
could you please explain a little more?
what's happening with -fno-rtti -fno-exceptions in CXXFLAGS

when I build zynaddsubfx it says 'CXX... not found', but no error message.

do I have to install some other package/.tcz?

thanks, regards, Ro

FLTK is built with those options, and usually they're copied from fltk-config, but your package seems not to be well behaved. Add those to your CXXFLAGS before configuring the package.

hm, i fear this  wasn't it.

i set the options  in 'ccmake .' -> '[t] toggle advanced mode' -> 'CMAKE_CXX_FLAGS' -> '-fno-rtti -fno-exceptions '
=> compiler error:
/home/tc/zynaddsubfx-2.4.4/src/Nio/OutMgr.cpp: In member function 'AudioOut* OutMgr::getOut(std::string)':
/home/tc/zynaddsubfx-2.4.4/src/Nio/OutMgr.cpp:80:74: error: 'dynamic_cast' not permitted with -fno-rtti
/home/tc/zynaddsubfx-2.4.4/src/Nio/OutMgr.cpp:81:1: warning: control reaches end of non-void function [-Wreturn-type]
make[2]: *** [src/Nio/CMakeFiles/zynaddsubfx_nio.dir/OutMgr.cpp.o] Error 1
make[1]: *** [src/Nio/CMakeFiles/zynaddsubfx_nio.dir/all] Error 2
make: *** [all] Error 2

tried without -fno-rtti: 'ccmake .' -> '[t] toggle advanced mode' -> 'CMAKE_CXX_FLAGS' -> '-fno-exceptions '
=> same errors as mentioned in my initial post

and ntk and ntk_images still not found.
