Re: [PD] linking libs with pd-lib-builder (was Re: fluid~)

Me and Dan have been pointing you to "-install_name @loader_path". Just do what pd-lib-builder does with shared helper libraries. Unfortunately I don't have time to come up and test a complete solution, but if you don't know how makefiles work already, that might be a good reason to start ;-)

For the record, me and lucas have been trying things in the background but we didn't find a solution.

I get an error

-lc -l:libfluidsynth.2.3.5.dylib -Wl,-R

ld: library not found for -l:libfluidsynth.2.3.5.dylib

clang: *error: *linker command failed with exit code 1 (use -v to
see invocation)

The.dylib file is in the same dir as the .c file?

can you try:

-l:libfluidsynth.2.3.5.dylib -Wl,-rpath,"./"

...

export LD_RUN_PATH="." in the makefile?
tried it and it builds, but still get the error
Library not loaded:
/usr/local/opt/fluid-synth/lib/libfluidsynth.2.dylib

hmm, not sure as I'd never done it.

...

can you try with windows at least?

I have it working:

I tweecked rhe makefile:

~~~~~~~~~

class.sources = fluid~.c

define forWindows

cflags += -I../fs-sources/include
ldlibs += -L../fs-sources/lib


endef

~~~~~~~


"fs-sources" conains the extracted package for win64 from
https://github.com/FluidSynth/fluidsynth/releases/tag/v2.1.6
<https://github.com/FluidSynth/fluidsynth/releases/tag/v2.1.6>


the fluid~ external folder has all these dlls:

fluid~.dll

libgobject-2.0-0.dll
libgthread-2.0-0.dll
libinstpatch-2.dll
libintl-8.dll
libsndfile-1.dll
libfluidsynth-2.dll
libglib-2.0-0.dll

    Reading here the 3th section:

    you can probably also try option:

    export LD_RUN_PATH="."

    in the makefile?

    I think this is necessary for Linux and macOS. On Windows it
    will auto work if the object and the lib are in the same dir.
