Libsourcey missing -fPIC compilation error

QUESTION

libuv - Limiting callback rate of idle event without blocking thread without multithreading

Asked 2018-Aug-22 at 08:30

I'm using libsourcey which uses libuv as its underlying I/O networking layer. Everything is setup and seems to run (haven't testen anything yet at all since I'm only prototyping and experimenting). However, I require that next to the application loop (the one that comes with libsourcey which relies on libuv's loop), also calls an "Idle function". As it is now, it calls the Idle CB on every cycle which is very CPU consuming. I'd need a way to limit the call-rate of the uv_idle_cb without blocking the calling thread which is the same the application uses to process I/O data (not sure about this last statement, correct me if i'm mistaken).

The idle function will be managing several different aspects of the application and it needs to run only x times within 1 second. Also, everything needs to run one the same thread (planning to upgrade an older application's network infrastructure which runs entirely single-threaded).

This is the code I have so far which also includes the test I did with sleeping the thread within the callback but it blocks everything so even the 2nd idle cb I set up has the same call-rate as the 1st one.

Solved the problem by using uv_timer_t and uv_timer_cb (Hadn't digged into libuv's doc yet). CPU usage went down drastically and nothing gets blocked.

Libsourcey missing -fPIC compilation error

Asked 2018-Aug-22 at 08:27

I'am trying to run the LibSourcey to use the Webrtc Streaming Server.

The thing is that i can't seem to make it work. I struggled to cmake the project on my Ubuntu 16.04(Regexp in cmake files) but now its fixed . The problem that i actually got is a shared object bug at compiling time :

You have a linkage error, not a compilation error. You haven't run into a bug, you have just attempted a linkage that cannot work.

You are trying to build a shared library libscy_av.so. All the object files that are linked in a shared library must consist of Position Independent Code. To generate such an object file with gcc, you compile with the option -fPIC.

The linker discovers that your shared libary requires the object file options.o, which is a member of the static library libswresample.a. It then discovers that this options.o is not PIC, and so cannot be linked in a shared library. The linkage fails and the linker advises you that options.o must be recompiled with the -fPIC compiler option.

To comply with that advice, you would have to rebuild the static library libswresample.a from source, with -fPIC added to the compiler flags.

You might do that, but it is unusual for object files in a static library to be PIC, and there is an easier option. Your mistake was in linking against the static version of libswresample (libswresample.a) rather than the shared version (libswresample.so), which will be PIC. Just correct that mistake. If you install libswresample.a from a dev package provided by your package manager, then it will also provide libswresample.so. If you have built libswresample from source, then the build system will also build both.
