Our current sccache build links in openssl's libraries dynamically. The
sonames of the dynamic libraries linked in are specific to the
CentOS/Fedora-ish systems that we build on; attempting to run the
generated sccache binaries on different systems (e.g. Debian-ish) will
result in failure. All of our current automation images are
CentOS-based, but for various reasons, Debian-based images may be used
in the future, and it would be great to have an sccache binary to run on
such systems as well. (It might also be interesting to distribute the
sccache binary we use to local developers as well, but that's a bit
further off.)
Therefore, this patch alters the sccache build on Linux to use static
linking for openssl. We cannot use the system openssl we build on
because the system openssl links to libkrb5, and the distribution we use
for the system images does not provide static libraries of libkrb5.
Building openssl ourself enables us to eliminate the libkrb5 dependency.
An sccache binary from builds with this patch depends on the following
libraries:
froydnj@hawkeye:~$ ldd sccache2/sccache
linux-vdso.so.1 => (0x00007ffe02b39000)
libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007ff0e7403000)
librt.so.1 => /lib/x86_64-linux-gnu/librt.so.1 (0x00007ff0e71fb000)
libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007ff0e6fdd000)
libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007ff0e6dc6000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007ff0e69fc000)
/lib64/ld-linux-x86-64.so.2 (0x0000557c8540b000)
libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007ff0e66f2000)
which are standard on any Linux distribution.
