@ -234,57 +234,21 @@ After these fixes, the command `make` is run, with some new errors:
* When there is an `#if defined(ANDROID)`, add ` || defined(ESP32)` after, so that `malloc.h` is included and `memalign` is used
* *#error "<dirent.h> not supported"*
* *glob.cpp: #error "<dirent.h> not supported"*
The ESP32 doesn't support directories (which are emulated with the filenames, like `mydir/mysubdir/myfile.c`).
**FIX:** Modify `modules/core/src/glob.cpp`
* Add the following code after line 136:
The `glob.cpp` file includes the file `xtensa-esp32-elf/sys-include/dirent.h`, which includes `xtensa-esp32-elf/sys-include/sys/dirent.h`, which causes this error. This is because the filesystem related functions are defined in the ESP-IDF repository (in `components/vfs/`). The `vfs/include/sys/dirent.h` header must therefore be included in `glob.cpp:135` instead of `<dirent.h>`:
``` c++
#if defined(ESP32)
#include <sys/unistd.h>
#include "esp_dirent.h"
#include <sys/stat.h>
const char dir_separators[] = "/";
namespace {
struct dirent {
const char *d_name;
};
struct DIR {
dirent ent;
DIR() { }
~DIR()
{
if (ent.d_name)
delete[] ent.d_name;
}
};
DIR* opendir(const char* path)
{
DIR* dir = new DIR;
dir->ent.d_name = 0;
// TODO implement (point the first file starting with 'path' in its name)
return dir;
}
dirent* readdir(DIR* dir)
{
// TODO: implement (point to the next file with 'path' in its name)
return &(dir->ent);
}
void closedir(DIR* dir)
{
delete dir;
}
}
#else
/* ... */
```
The function are not implemented yet. Must be implemented if files reading/writing in SPIFFS needed.
This `esp_dirent.h` file is the `vfs/include/sys/dirent.h` copied into `modules/core/src/` in OpenCV sources.
