Errors while compiling gstreamer plugins base

Takido · 06-06-2012, 05:49 AM

Hi,

I'm using Gentoo and trying to compile the gst-plugins-base package. The configuring phase runs well but while making, I'm getting the error :

Quote:

./.libs/libgsstag-0.10.so: undefined reference to `gst_date_time_get_minute`

And a dozen of errors like this one.
Gstreamer is installed and I've checked that all the references that can't be found by the compiler are actually present in the includes.
Does someone have a clue about how to solve my problem ?

Thanks.

this is a message from the linker, it means it is looking for libs, not includes. So probably the gst plugin libs are not available or there is a missing/misconfigured parameter somewhere.

Takido · 06-06-2012, 06:04 AM

Thanks for your answer.
What is strange is that the references the compiler is complaining about are present in the .h files.
So yes, I think there may be a parameter problem, but since I'm using portage, I don't know where the error could be.

Do you know what parameter I should check ?

would be better to see more of the compile log

You're right, indeed.

the unresolved symbol gst_date_time_get_minute should be found in libgstreamer-0.10.so and gst_byte_writer_init_with_size in libgstbase-0.10.so.
You can check it by nm <libname> | grep <symbol> for example. So the question is if the libs in /usr/lib are really available and contains these symbols

Takido · 06-06-2012, 06:38 AM

I see.

I tried to find out whether these symbols were supposed to be and indeed, they aren't.

Quote:

nm /usr/lib/libgstreamer-0.10.so | grep gst_date_time_get_minute

returns "no symbols".

And so does

Quote:

nm /usr/lib/libgstbase-0.10.so | grep gst_byte_writer_init_with_size

I tried to recompile gstreamer many times before, but it did not change anything. I can't get what I did wrong...

can you please try: file /usr/lib/libgst*

do you build a 32bit or 64bit lib? you can try to rebuild gstreamer without -s (because nm does not work on stripped objects).

Takido · 06-06-2012, 08:18 AM

I'm building a 32bit lib.
I'm sorry, but what do you mean by building without -s ?

pan64 · 06-06-2012, 08:27 AM

the libs are stripped and you wrote you built them. During the build (if you could see the log) there is a -s flag in the link command. If you could remove it you should be able to check the content with nm.

Takido · 06-06-2012, 08:30 AM

Okay, I got it.
However, I actually used the portage tool to build them. So I'll try to build them manually.

Thanks.

Takido · 06-06-2012, 09:06 AM

Since I did not manage to remove the "-s", I tried to build gstreamer from its sources.
After this, when I tried to compile gst-plugins-base from sources, I got the same error as before... But when emerging it using Portage, it worked !

Now I need to cross-compile it.
Thank you !
