eclipse - Undefined reference in C with gcrypt.h -

i'm trying utilize library gcrypt.h show error:

undefined reference `gcry_md_get_algo_dlen'

the code is:

int algo = gcry_md_sha1; unsigned int hash_len = gcry_md_get_algo_dlen(algo); unsigned char hash[hash_len];

how can prepare it?

make sure have recent version of library http://www.gnupg.org/download/#libgcrypt

if have right version create sure added library linker settings in eclipse.

to so:

right-click on project -> properties / c/c++build / settings / gcc c++ linker / libraries

there add together libraries "gcrypt" ( don't @ "lib" ) , create sure ( if lib isnt under scheme path ) add together path library lies.

c eclipse

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
