File is too small to be a valid STL file. error

[foulde]

Hi ! i am having an issue with a stl file of a 2d square plate of 72 triangles and 216 vertices i am trying to use the c++ header only as mentioned in the c++ example but i get the following error :

terminate called after throwing an instance of 'std::runtime_error'
what(): File is too small to be a valid STL file.
Aborted (core dumped)

i am using the following code :

`#include
#include // std::ifstream
#include<string.h>
#include "../lib/stl.h"

// char filename[] = "square_plate.stl";

// char filename[] = "plat100x100.stl";
char filename[] = "square_plate.stl";

int main(){

std::ifstream file(filename, std::ios::binary);
if(!file.is_open()){
    std::cerr << "Error: Unable to open file '" << filename << "'" << std::endl;
}

// Deserialize the triangles in either binary or ASCII format
std::cout << "\n\nthis is the code \n\n"; 
std::vector<openstl::Triangle> triangles = openstl::deserializeStl(file);
file.close();

const auto& [vertices, faces] = convertToVerticesAndFaces(triangles);

return 0; 

}
`

Best regards

@foulde Thanks for the issue!

Is there any way you can share you square_plate.stl file? Is your file format binary or ASCII (human readable) ?

As specified by the binary STL file format specs, 84 bytes is the mandatory minimum file size for any binary STL, even with 0 triangles. Either your file is not formatted with the STL specs or corrupted, either there is a flaw in the ASCII detection, which I have not discovered yet.
