Thread: psql /usr/lib/libgcc dependency in pg 8.3
I notice that when I build 8.3.1 psql on OS X (10.5.2) there is now a library dependency on /usr/lib/libgcc_s.1.dylib even though I specified "--without-readline" in configure. I don't see this dependency with psql 8.2. Is there a way to remove this library requirement in the build? I want to build a binary that will run on 10.3 and I don't think it has /usr/lib/libgcc. Thanks, John DeSoi, Ph.D.

Whatever would make you think that readline has anything to do with
that?

I seem to recall there's some sort of compatibility stuff for building
back-compatible binaries on the Xcode disk, but it's not installed
by default.

Just an uneducated guess because long ago not adding that flag required additional library dependencies. I forgot to include that when I compiled the first time and there was no error. I used to have to tell it explicitly where to find the readline library. > > >> I want to build a binary that will run on >> 10.3 and I don't think it has /usr/lib/libgcc. > > I seem to recall there's some sort of compatibility stuff for building > back-compatible binaries on the Xcode disk, but it's not installed > by default. OK, so it is really and XCode issue and nothing that changed with 8.3. Thanks, John DeSoi, Ph.D.

It appears to be a support library for gcc for certain routines that are architecture specific or language specific like stack unwinding, etc. Apparently if gcc is compiled to know that the runtime can do it (ie, you're using glibc) then gcc can be configured without it. There is apparently a -static-libgcc option if you dont want to use the shared version.
