Error using calllib.
The pointer type must match the data type

Error geodesic_distance_and_source (line 19)
[num_vertices, d, s] = calllib(geodesic_library, 'distance_and_source_for_all_vertices', algorithm.id, tmp, tmp1);

Error example3 (line 30)
[source_ids, distances] = geodesic_distance_and_source(algorithm); %for every vertex, figure out which source it belongs to

Could you please help me solve this problem? Thank you~

I did what you said, but there were still mistakes.

出错 loadlibrary>getLoadlibraryCompilerConfiguration (line 520)

出错 loadlibrary (line 263)

出错 geodesic_new_mesh (line 7)
loadlibrary([geodesic_library '.dll'], hfile);

出错 example1 (line 13)
mesh = geodesic_new_mesh(vertices,faces); %initilize new mesh
}

When the dll built with debug configuration is used, Matlab example2 pops up a window saying that

“Assertion failed！ geodesic_algorithm_exact.h Line:1166 
Expression:p->start() < p->stop()” 

Reasonable results can still be obtained if you click the button Ignore.
If the dll built with release is used, Matlab will crash.

Is it necessary to have geodesic_algorithm_exact.h Line:1166?

assert(p->start() < p->stop());

Of course it is a straightforward workaround to comment out that line, which has been tested.

Error geodesic_new_mesh (line 7)
loadlibrary([geodesic_library '.dll'], hfile);
when run "example1.m"

and please tell me how to do this:
{
Build
Windows + MSVC
C++ executable

Build projects example0 and example1 in geodesic.sln.
MATLAB API functions

Build project geodesic in geodesic.sln.
Copy built library geodesic_(debug|release).dll to the folder matlab.
Run example[1-5] in Matlab.
}

Hi, thank you for creating geodesic_matlab!

For some inputs, geodesic_new_mesh causes a segmentation fault. This issue occurs on line 32, where the library is called:

[id, tmp1, tmp2, num_edges, edges] = calllib(geodesic_library, 'new_mesh', length(p)/3, p, length(t)/3, t, 1, tmp);

To reproduce:

load points.mat
load tri.mat
geodesic_new_mesh(points, tri)

I've included points.mat, tri.mat, and the crash report in new_mesh_crashes.zip

Any suggestions would be much appreciated!

Hi, thank you very much for the wonderful solutions on the geodesic distance computation toolbox. It works with windows and old macOS perfectly. However, I encountered issues with new Apple model with M1 chip. The error was:

"... (mach-o file, but is an incompatible architecture (have 'arm64', need 'x86_64')), ..."

I would appreciate it sincerely if you can help with this issue. Many thanks!

Sir or Madam:
At first, thanks for your effort.
Well I met a problem when using your code. Honestly I am not a skillful programmer. I only make some basic appliction. I intalled MATLAB 2016b and VS2013, I downloaded your code, and I followed your advice:
1.Build projects example0 and example1 in geodesic.sln.
2.Copy built library geodesic.dll to the folder matlab.
then I run example1in Matlab. But the matlab shows

   >> example1
   错误使用 loadlibrary
   加载库 "geodesic_debug.dll" 时出错
   找不到指定的模块。
   出错 geodesic_new_mesh (line 7)
    loadlibrary([geodesic_library '.dll'], hfile);
   出错 example1 (line 13)
   mesh = geodesic_new_mesh(vertices,faces);         %initilize new mesh
   原因:
       错误使用 loaddefinedlibrary
       找不到指定的模块。   

I don know whats wrong?
btw, My email address is [email protected]，waiting for you reply, thank you
