So it seems you are not developing new applications but trying to compile/build current versions of existing applications on Solaris 10. Given the fact that Solaris 10 is ten years old, it is expected for these applications not to be easily portable to Solaris 10. As already stated, you might have better luck with Solaris 11.x. Why are you targeting Solaris 10 in the first place?
GIT-REMOTE-FD(1) Git Manual GIT-REMOTE-FD(1)NAME
git-remote-fd - Reflect smart transport stream back to caller
SYNOPSIS
"fd::<infd>[,<outfd>][/<anything>]" (as URL)
DESCRIPTION
This helper uses specified file descriptors to connect to a remote git server. This is not meant for end users but for programs and scripts
calling git fetch, push or archive.
If only <infd> is given, it is assumed to be a bidirectional socket connected to remote git server (git-upload-pack, git-receive-pack or
git-upload-achive). If both <infd> and <outfd> are given, they are assumed to be pipes connected to a remote git server (<infd> being the
inbound pipe and <outfd> being the outbound pipe.
It is assumed that any handshaking procedures have already been completed (such as sending service request for git://) before this helper
is started.
<anything> can be any string. It is ignored. It is meant for providing information to user in the URL in case that URL is displayed in some
context.
ENVIRONMENT VARIABLES
GIT_TRANSLOOP_DEBUG
If set, prints debugging information about various reads/writes.
EXAMPLES
git fetch fd::17 master
Fetch master, using file descriptor #17 to communicate with git-upload-pack.
git fetch fd::17/foo master
Same as above.
git push fd::7,8 master (as URL)
Push master, using file descriptor #7 to read data from git-receive-pack and file descriptor #8 to write data to same service.
git push fd::7,8/bar master
Same as above.
