Subject: [PATCH] M!28 - Include LDFLAGS in gtkdoc-scangobj command line
When a library provides no way to find linker flags for linking with it,
the build system usually depends on the user to necessary put -L flags
in LDFLAGS environment variable in order to find it. However, GtkDoc
module constructs the command line by itself, and it forgets to add
LDFLAGS to the command line of gtkdoc-scangobj.
It is especially important to include LDFLAGS on non-GNU systems. For
example, FreeBSD libc doesn't include a gettext implementation. GLib
requires gettext, and it pulls in an external gettext runtime for it.
However, gettext-runtime doesn't include a .pc file, so LDFLAGS is
required if gettext-runtime isn't installed in the same prefix as GLib.
Failing to include LDFLAGS in --ldflags passed to gtkdoc-scangobj can
result in a linking error because -lintl cannot be found.
In evolution-data-server we are lucky most of the time because it
depends on a lot of external libraries. These external libraries are
likely to be installed in the same prefix as gettext-runtime, so not
using LDFLAGS doesn't cause linking failure because required flags are
already pulled in by other libraries. In fact, this problem was found
when building libical, which uses a similar GtkDoc.cmake file.
In addition to the change to include LDFLAGS, this commit also changes
the following things:
- Instead of constructing _scangobj_ldflags in reverse order, do it in
normal order. Appending is easier to understand than prepending, and
the linker also interprets -L and -l flags in normal order.
- Move -L${LIB_INSTALL_DIR} to the bottom. This is what the comment
says, and it is expected to work because we no longer constructs
_scangobj_ldflags in reverse order.
