Hi,

I haven't involved in C programming for quite a while. I want to confirm
this question but couldn't find in comp.lang.c FAQ, and GCC Frequently
Asked Questions. Anyway, here is the question:

How can I link a lib statically?

Although the question is simple, please answer comprehensively. I.e., what
is the command line format, what is required for the linking.
Specifically, I want to link avcodeccvs & avformat statically while lz is
linked dynamically. how can I do that? This is what I tried:

$ g++ -g -Wall -o lnk-test lnk-test.C -lz -static -lavcodeccvs -lavformat
/usr/bin/ld: cannot find -lavcodec
collect2: ld returned 1 exit status

Please note, this is ok:

$ g++ -g -Wall -o lnk-test lnk-test.C -lavcodec -lavformat -lz

Further, in the libavcodeccvs-dev package, only .so type of libs are provided:

/usr/lib/libavcodec.so
/usr/lib/libavformat.so

please elaborate. Thanks

This seems to be a gcc question -> news:gnu.gcc.help
Look into the newsgroup's archives

Note that g++ is used for compilation of C++.
In this case, ask in news:gnu.g++.help

Hi, sorry to have posted OT question here. I re-posted it again in
gnu.g++.help.

However, by taking a look at the recent posts, I get a feeling that the NG
is abandoned, and is full of spams. Check the subject list (and count)
below.

As I said, I searched and looked before raised the question.

Yeah, well, thanks so much for reposting their spam here.

Your question clearly wasn't about C, and probably wasn't about C++
either. I'm sorry if you're having trouble getting help elsewhere,
but that doesn't mean it's topical here.

There were *some* topical posts there. You might try posting and
seeing if anyone answers. If that doesn't work, there are a number of
gcc-related mailing lists; you can find them with a quick Google
search.

We must do something. This is something. Therefore, we must do this.

ok, thanks for clear it up. I'll try elsewhere.
