Re: [fluid-dev] FluidSynth Example on MacOS gives segfault

[Ceresa Jean-Jacques]

 

Hi, Rohit

 

I suspect the "segmentation fault" occurs during the execution of fluid_synth_sload(). This souldn't occur

even if the soundfont file is malformed.

 

Please, would you try these 2 simple tests and report each results:

 

1) First test: use a well know correct sf2 (i.e GUGSv1_47.sf2).

 

2) Second test: still using JJSF2.SF2, In the source file , add "printf" before and after fluid_synth_sload() like this:

....

printf("fluidsynth_simpe: start  loading the soundfont file\n");

/ *Load the soundfont */

if(fluid_synth_sload(synth, argv[1], 1) == -1)

{

     fprintf(stderr, "Failed to load the SoundFont\n");

     err = 4;

     goto cleanup;

}

printf("fluidsynth_simpe: end  loading the soundfont file\n");

.....

Cheers.

Hi, I'm just trying to acquaint myself with FluidSynth by testing out a few example codes given in the docs.

I tried to run the code written here, with a random sf2 file that I found online. I run into the following warning and segfault. I'm not sure how to proceed. Please help me out. Thanks.
