[gentoo-user] question about revdep-rebuild

[Tamas Sarga]

Hi,

I confused about revdep-rebuild. I thought that revdep-rebuild without
any parameter would investigate all of my bin, and a --soname parameter
will investigate just about this .so file.
Today I had done an emerge -uD world and openssh didn't work anymore. I
read the logs, which said do a revdep-rebuild --soname libcom_err.so.3.
The update did more library update, so I did revdep-rebuild without any
parameter, and it didn't show anything, but ssh didn't work. I did the
adviced revdep-rebuild --soname libcom_err.so.3 and it showed openssh.
My question is what exactly does revdep-rebuild without any parameter?
After reemerge of openssh the sun shines to me again.

TIA.
Cheers,

As I understand, just running revdep-rebuild without parameters will
search for binaries linked against now missing libraries. Running it
with a --soname looks for binaries linked against existing libraries,
but whose version is now different. So they do different things.

Hope it helps.
Cheers,
Renat

revdep-rebuild -p   will investigate
revdep-rebuild   will take action

Run with -p first to be safe.

It uses the output of ldd to determine if a file has broken dynamic
linkage dependencies.  If it does the owning package will be rebuilt.

Again it uses ldd, but this time to check the sonames of the libraries
that the file is dynamically linked to.  If the given soname is found
then the owning package is rebuilt.  This will happen even if ldd would
have shown the dynamic link as being OK.
