Olá, comecei a pesquisar sobre alguma api/sdk que me ajudasse a comunicar um leitor biomérico(Eikon Upek), com o pc, de modo a extrair,comparar,gravar em banco de dados as digitais. Só que estou com alguns problemas, primeiro que o site www.upek.com do fabricante simplesmente desapareceu... e não conseguia achar uma api/sdk free ou open source. Achei essa api/sdk https://github.com/FingerJetFXOSE/FingerJetFXOSE e estou a estudando nesse momento. Minha dúvida é a seguinte, não consigo compilar o exemplo que vem feito nela, e vim pedir a ajuda de vocês para resolver isso. O erro que aparece aqui é undefined reference to `fjfx_create_fmd_from_raw', vou por o código para vocês darem uma olhada. #include <stdio.h> #include <stdlib.h> #include "fjfx.h" int main(int argc, char ** argv) { FILE *fp = 0; int height, width, gray; unsigned int size; void * image = 0; size_t n; int err; unsigned char tmpl[FJFX_FMD_BUFFER_SIZE] = {0}; if(argc != 3 || argv[1] == NULL || argv[2] == NULL) { printf("Fingerprint Minutia Extraction\n" "Usage: %s <image.pgm> <fmd.ist>\n" "where <image.pgm> is the binary PGM (P5) file that containing 500DPI 8-bpp grayscale figerprint image\n" " <fmd.ist> is the file where to write fingerprint minutia data in ISO/IEC 19794-2 2005 format\n", argv[0]); return -1; } fp = fopen(argv[1], "rb"); if (fp == 0) { printf("Cannot open image file: %s\n", argv[1]); return 9; } n = fscanf(fp, "P5%d%d%d", &width, &height, &gray); if (n != 3 || gray > 256 || width > 0xffff || height > 0xffff || gray <= 1 || width < 32 || height < 32) { printf("Image file %s is in unsupported format\n", argv[1]); fclose(fp); return 10; } size = width * height; image = malloc(size); if (image == 0) { printf("Cannot allocate image buffer: image size is %dx%d", width, height); return 12; } n = fread(image, 1, size, fp); fclose(fp); fp = 0; if (n != size) { printf("Image file %s is too short\n", argv[1]); free(image); return 11; } size = FJFX_FMD_BUFFER_SIZE; err = fjfx_create_fmd_from_raw(image, 500, height, width, FJFX_FMD_ISO_19794_2_2005, tmpl, &size); free(image); image = 0; if (err != FJFX_SUCCESS) { printf("Failed feature extraction\n"); return err; } fp = fopen(argv[2], "wb"); if (fp == 0) { printf("Cannot create output file: %s\n", argv[2]); return 14; } n = fwrite(tmpl, 1, size, fp); fclose(fp); if (n != size) { printf("Cannot write output file of size %d\n", size); free(image); return 15; } return 0; } #ifndef __fjfx_h #define __fjfx_h #ifdef __cplusplus extern "C" { #endif // __cplusplus // Error codes #define FJFX_SUCCESS (0) // Extraction succeeded, minutiae data is in output buffer. #define FJFX_FAIL_IMAGE_SIZE_NOT_SUP (1) // Failed.
