c++ - Can I build a shared library by linking static libraries? -

i have bunch of static libraries (*.a), , want build shared library (*.a) link against static libraries (*.a). how can in gcc/g++? thanks!

you can (just extract .o files , link them -shared create .so), whether works, , how works, depends on platform , whether static library compiled position-independent code (pic). on platforms (e.g. x86_64), non-pic code not valid in shared libraries , not work (actually think linker reject create .so). on other platforms, non-pic code work in shared libraries, in-memory re-create of library not sharable between different programs using or different instances of same program, result in huge memory bloat.

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...
