*******************************************************************************
** Building TigerVNC
*******************************************************************************
==================
Build Requirements
==================
-- autoconf 2.57 or later
-- automake 1.7 or later
-- libtool 1.4 or later
-- NASM
* 0.98 or later is required for a 32-bit build
* NASM 2.05 or later is required for a 64-bit build
* NASM 2.07 or later is required for a 64-bit build on OS X. This can be
obtained from MacPorts (http://www.macports.org/).
The NASM 2.05 RPMs do not work on older Linux systems, such as Enterprise
Linux 4. On such systems, you can easily build and install NASM 2.05
from the source RPM by executing the following as root:
ARCH=`uname -m`
wget http://www.nasm.us/pub/nasm/releasebuilds/2.05.01/nasm-2.05.01-1.src.rpm
rpmbuild --rebuild nasm-2.05.01-1.src.rpm
rpm -Uvh /usr/src/redhat/RPMS/$ARCH/nasm-2.05.01-1.$ARCH.rpm
NOTE: NASM build will fail if texinfo is not installed.
-- GCC v4.1 or later recommended for best performance
-- X11 development kit
-- If building Xvnc:
* Python v2.3 or later
* zlib v1.2 or later
* OpenSSL v0.9.7 or later
=================
Building TigerVNC
=================
The following procedure will build the TigerVNC viewer on Linux and Unix
systems. On 64-bit systems, this may build a 32-bit version of TigerVNC,
depending on the default compiler configuration for your system. See below for
specific build instructions for 64-bit systems.
cd tigervnc
autoreconf -fiv
sh ./configure [additional configure flags]
make
NOTE: Running autoreconf is only necessary if building TigerVNC from the SVN
repository.
Building the TigerVNC server (Xvnc) is a bit trickier. On newer systems, such
as Fedora, Xvnc is typically built to use the X11 shared libraries provided
with the system. This requires a system with Xorg 7.4 or later, however.
Systems with older versions of Xorg must build a "legacy-friendly" version of
the TigerVNC server. This is accomplished by downloading and building the
more recent Xorg modules in a local directory and then building Xvnc such that
it links against the local build of these libraries, not the X11 libraries
installed on the system. The "build-xorg" script in the TigerVNC source
distribution automates this process.
The following procedure will build both the TigerVNC viewer and a
"legacy-friendly" version of the TigerVNC server:
cd tigervnc
unix/build-xorg init -version 7.4
unix/build-xorg build -version 7.4 [-static] [additional configure flags]
Passing an argument of "-static" to the build command line will generate a
version of Xvnc that has no external dependencies on the X11 shared libraries
or any other distribution-specific shared libraries. This version of Xvnc
should be transportable across multiple O/S distributions. The legacy-friendly
build should work on RedHat Enterprise 4, its contemporaries, and later
systems. It probably will not work on older systems. It has not been tested
on non-Linux systems (yet).
build-xorg can also be used to rebuild just the TigerVNC server and viewer,
once the X11 modules and other dependencies have been built the first time.
This is convenient for testing changes that just apply to the TigerVNC source
code. To accomplish this, run:
unix/build-xorg rebuild [additional make flags]
For instance,
unix/build-xorg rebuild clean
will clean both the Xvnc and vncviewer builds without destroying any of the
build configuration or module dependencies.
==================================
Build Recipes for Specific Systems
==================================
32-bit Build on 64-bit Linux
----------------------------
Add
--host i686-pc-linux-gnu CFLAGS='-O3 -m32' CXXFLAGS='-O3 -m32' LDFLAGS=-m32
to the configure and build command lines.
64-bit Build on 64-bit OS X
---------------------------
Add
--host x86_64-apple-darwin NASM=/opt/local/bin/nasm
to the configure command line. NASM 2.07 or later from MacPorts must be
installed.
32-bit Build on 64-bit OS X
---------------------------
Add
CFLAGS='-O3 -m32' CXXFLAGS='-O3 -m32' LDFLAGS=-m32
to the configure command line.
64-bit Backward-Compatible Build on 64-bit OS X
-----------------------------------------------
Add
--host x86_64-apple-darwin NASM=/opt/local/bin/nasm \
CFLAGS='-isysroot /Developer/SDKs/MacOSX10.5.sdk \
-mmacosx-version-min=10.5 -O3' \
CXXFLAGS='-isysroot /Developer/SDKs/MacOSX10.5.sdk \
-mmacosx-version-min=10.5 -O3' \
LDFLAGS='-isysroot /Developer/SDKs/MacOSX10.5.sdk \
-mmacosx-version-min=10.5'
to the configure command line. The OS X 10.5 SDK, and NASM 2.07 or later from
MacPorts, must be installed.
32-bit Backward-Compatible Build on 64-bit OS X
-----------------------------------------------
Add
CC=gcc-4.0 CXX=g++-4.0 CFLAGS='-isysroot /Developer/SDKs/MacOSX10.4u.sdk \
-mmacosx-version-min=10.4 -O3 -m32' \
CXXFLAGS='-isysroot /Developer/SDKs/MacOSX10.4u.sdk \
-mmacosx-version-min=10.4 -O3 -m32' \
LDFLAGS='-isysroot /Developer/SDKs/MacOSX10.4u.sdk \
-mmacosx-version-min=10.4 -m32'
to the configure command line. The OS X 10.4 SDK must be installed.
Building VeNCrypt support on OS X
---------------------------------
VeNCrypt requires GnuTLS, which is not available on OS X systems by default.
However, it can be obtained from MacPorts (http://www.macports.org/). The
easiest way to build TigerVNC using this version of GnuTLS is simply to
modify the CPATH and LIBRARY_PATH environment variables to include /opt/local,
i.e.:
export CPATH=/opt/local/include
export LIBRARY_PATH=/opt/local/lib
and then build TigerVNC as you would normally. However, this produces run-time
dependencies on the .dylib files in /opt/local/lib. To statically link with
GnuTLS, add the following monstrosity to the configure command line:
GNUTLS_CFLAGS=-I/opt/local/include \
GNUTLS_LDFLAGS='/opt/local/lib/libgnutls.a /opt/local/lib/libgcrypt.a \
/opt/local/lib/libgpg-error.a /opt/local/lib/libz.a \
/opt/local/lib/libtasn1.a /opt/local/lib/libiconv.a \
/opt/local/lib/libintl.a -framework CoreFoundation'
*******************************************************************************
** Creating Release Packages
*******************************************************************************
The following commands can be used to create various types of release packages:
make dmg
Create Macintosh package/disk image. This requires the PackageMaker
application, which must be installed in /Developer/Applications/Utilities.
make udmg
On 64-bit OS X (10.5 "Leopard") and later, this creates a version of the
Macintosh package/disk image which contains universal i386/x86-64 binaries.
The 32-bit fork of these binaries is backward compatible with OS X 10.4 and
later (OS X 10.4 compatibility SDK required.) If building on OS X 10.6
("Snow Leopard") or later, the 64-bit fork can be made backward compatible
with 10.5 by using the instructions in the "Build Recipes" section.
