hi i am trying to read a matrix with the following code #include <stdio.h> #include <stdlib.h> #include <gsl/gsl_matrix.h> #include "lavision.h" int main(void) { image_header header; gsl_matrix *m; fread(&header, sizeof(image_header), 1, stdin); m = gsl_matrix_alloc(header.rows, header.columns); gsl_matrix_fread(stdin, m); gsl_matrix_free(m); return 0; } running it as ./a.out < test.imx fails with gsl: fwrite_source.c:64: ERROR: fread failed Program received signal SIGABRT, Aborted. 0x401f2d21 in __kill () from /lib/libc.so.6 when i traced it in ddd i found that it fails in int FUNCTION (gsl_matrix, fread) (FILE * stream, TYPE (gsl_matrix) * m) { int status = 0; const size_t size1 = m->size1; const size_t size2 = m->size2; const size_t tda = m->tda; if (tda == size2) /* the rows are contiguous */ { status = FUNCTION (gsl_block, raw_fread) (stream, <<<<<< error! m->data, size1 * size2, 1); however fwrite_source.c line 64 is int FUNCTION (gsl_matrix, fwrite) (FILE * stream, const TYPE (gsl_matrix) * m) { int status = 0; const size_t size1 = m->size1; const size_t size2 = m->size2; const size_t tda = m->tda; if (tda == size2) /* the rows are contiguous */ { <<<<<line 64! status = FUNCTION (gsl_block, raw_fwrite) (stream, m->data, size1 * size2, 1); so while supposed to read gsl fails in a low level write routine?? i am completely confused. and yes i compiled gsl myself so sources should match libraries used. -- Dr. Ivo Alxneit Laboratory for Solar Technology phone: +41 56 310 4092 CH-5232 Villigen fax: +41 56 310 2624 Paul Scherrer Institute Switzerland
