autotools - Abstracting include paths and library names with pkg-config? -


i'm working project goes 1 of 2 package names, depending on distribution. on debian , derivatives, package name libcrypto++. on fedora , derivates, called libcryptopp. (the official project name crypto++).

users write code, , things like:

#include <crypto++/aes.h>

and later, link library -lcrypto++.

obviously, using "debian conventions" breaks things on fedora (and vice versa). see, example, how change include file path autotools?

i'm trying determine can used abstract differences away user's code "just works".

can pkg-config files used handle differences? if so, how handle #include <crypto++/...> versus #include <cryptopp/...> found in user code? (i'm concerned header clashes, openssl , crypto++ both providing aes.h).

if not, can issues caused different names on different platforms?

there's nothing built-in auto-tools automatically. it's unusual need.

there ways work. here couple:

  • make symlink in build tree, name like, pointing include tree. is, symlink libcrypto++ /usr/include/libcrytpopp; use #include <libcrypto++/mumble> in source. can make symlink configure.

  • generate new c macro definition @ configure time (see ac_define) expands string holding prefix, e.g., "libcryptopp". use pasting in #include line include proper header. see this answer.

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now...
