painter and librfxcodec are enabled by default. --disable-* options
disables them.
Before:
--disable-painter Use included painter library (default: yes)
--disable-rfxcodec Use included librfxcodec library (default: yes)
After:
--disable-painter Do not use included painter library (default: no)
--disable-rfxcodec Do not use included librfxcodec library (default:
no)
Use XRDP_SOCKET_PATH in file_loc.h
Don't define any non-socket paths in file_loc.h, they should come from
the makefiles.
Define all paths unconditionally, they should not be defined elsewhere.
Pass XRDP_SOCKET_PATH as environment variable to the backends.
Rather than guess user's intention based on whether --prefix was
specified, use an explicit option to enable strict GNU Coding Standards
for installation directories.
The default is to use /etc and /var rather than corresponding directories
under prefix.
Use --enable-strict-locations in "make distcheck", it expects all
installed files to be under prefix.
Prefer openssl binary from the same location as the openssl library.
Make it possible to suppress certificate generation during install by
passing OPENSSL=: to make.
PKG_PROG_PKG_CONFIG does not exit if it fails to find pkg-config.
Continuing without pkg-config leads to misleading error messages when
checks for packages fail.
Since libpainter is going to become a subpackage, we can make librfxcodec
a subpackage as well.
With this change, librfxcodec is configured, built and linked to xrdp
automatically if enabled by "--enable-rfxcodec"
librfxcodec is packaged by "make dist" regardless of "--enable-rfxcodec"
librfxcodec/confgure is run unconditionally, it's needed for "make dist"
to work. But librfxcodec is only compiled if enabled.
The pixman library in not part of xrdp. If users see that "xrdp_pixman"
is not found, they might assume it is some xrdp specific library.
The Automake conditional is still XRDP_PIXMAN, but the pkg-config
variables become PIXMAN_LIBS and PIXMAN_CFLAGS.
The PKG_INSTALLDIR macro also enables --with-pkgconfigdir for easy
overrides.
PKG_INSTALLDIR is relatively new, it appeared in pkg-config 0.27. To
ensure we have a recent pkg.m4 copy, copy pkg.m4 to the m4 directory.
String literals are const in C++. Using this warnings moves us closer to
the stated goal of C++ compatibility, makes the code cleaner and lets
compilers optimize the code better.
Add m4/ax_append_compile_flags.m4 from Autoconf Archives for the
AX_APPEND_COMPILE_FLAGS macro and m4/ax_check_compile_flag.m4 as its
dependency.
Add Autoconf archive macros to check for -Wall and its dependencies.
Adjust m4/.gitignore to only ignore libtool macros.
Require Autoconf 2.65 for compatibility with Autoconf archive macros.
libdir is for shared and static libraries. Some xrdp libraries are loaded
dynamically from a non-standard directory, so they are used like modules.
Having separate libdir and moduledir would eventually allow to separate
dynamically loaded modules from shared libraries.
Automake 1.6.x cannot deal with conditional EXTRA_LIBS. Automake 1.7 and
1.7.1 cannot deal with line continuation in SUBDIRS.
It is important to have correct requirements to know what Automake
features can be used.
