Linking statically

[T]

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

tong

This seems to be a gcc question -> Look into the newsgroup's archives

In this case, ask in

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)

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.

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