Installation under a GNU operating system (such as GNU/Linux)
=============================================================
You need the GNU development tools plus the GTK+ library, version
1.3 or higher, installed on your system. Unpack the tarball, `cd'
into the new directory, configure, compile, and install GPA:
tar xvzf gpa-0.5.0.tar.gz
cd gpa-0.5.0
./configure
make
su -c "make install"
In order to do anything useful with GPA you also need the
GNU Privacy Guard (GnuPG) installed - see http://www.gnupg.org.
Please report any problems to gpa-dev@gnupg.org.
Installation under MS-Windows
=============================
Instead of compiling GPA by yourself, you probably want to download
the ready-to-use installer from http://www.gnupp.de, don't you? ;-)
Okay - here is how to compile your own `gpa.exe'!
In order to compile GPA you need the GNU development toolchain
consisting of a compiler, linker, a `make' utility, a Unix-like
command interpreter (shell), etc., plus the GTK+ library.
You can either cross-compile GPA from a Unix-like operating system
to MS-Windows, or compile it natively under MS-Windows. For security
reasons, we recommend to cross-compile GPA from an entirely free
operating system (such as GNU/Linux) whose source code you have
carefully reviewed before, line by line - or at least some
approximation to this.
There are (at least;-) four possibilities how to build a working
`gpa.exe' for MS-Windows:
1) Cross compile it from a Unix-like system to mingw32/MS-Windows.
2) Cross compile it from CygWin/MS-Windows to mingw32/MS-Windows.
3) Compile it semi-natively under CygWin with the `-mno-cygwin'
switch to generate mingw32/MS-Windows output.
4) Compile it natively using the CygWin environment with the
mingw32 compiler.
For (2) through (4), you need to install the CygWin development
tools, available from http://www.cygwin.com.
In all four cases, you need GTK+ for mingw32/MS-Windows. Get it from
http://www.gimp.org/win32/.
Methods (3) and (4) are untested, but they should work more or less
straightforward. In the following, I will explain (1) and (2).
Once CygWin is installed, the procedure for (1) and (2) is exactly
the same:
* Download the source of the mingw32 GCC and binutils from
http://www.mingw.org.
* Unpack the archives. This will create two new sub-directories.
* In both sub-directories, type:
./configure --host=i386-mingw32 --target=i386-mingw32'
make
su -c "make install"
(See the GCC installation instructions for details.)
* Install GTK+ for mingw32 in the /usr/local/i386-mingw32 directory.
* Unarchive the GPA source and `cd' to the new subdirectory
`gpa-0.5.0'.
The next step is to "configure" GPA itself.
To compensate for some bugs in older versions of `autoconf' and
friends (and some other hacks), I call `configure' indirectly using
the following script:
8< ---- configure.pg -----------------------------------------------
#!/bin/sh
./configure --silent \
--prefix=$HOME/usr/i386-mingw32 \
CFLAGS="-g -O -Wall -mwindows" \
--with-gtk-prefix=$HOME/usr/i386-mingw32 \
--host=i386-mingw32 --target=i386-mingw32
rm -f src/Makefile.orig
mv src/Makefile src/Makefile.orig
cat src/Makefile.orig | sed -e 's/ #PG#//g' > src/Makefile
rm -f config.h.orig
mv config.h config.h.orig
cat config.h.orig \
| sed -e 's/^#include "gpadefs\.h"/\/* #include "gpadefs.h" -- disabled by $0 *\//' \
> config.h
cat - >> config.h << EOF
/* Fixes by $0 */
#define HAVE_PROCESS_H 1
#define HAVE_MEMICMP 1
#define HAVE_DOSISH_SYSTEM 1
#define HAVE_DRIVE_LETTERS 1
#define USE_SIMPLE_GETTEXT 1
#include "gpadefs.h"
EOF
echo "timestamp" > stamp-h
cat - > gpadefs.h << EOF
/* Generated by $0 */
#define GPA_LOCALEDIR "C:\\\\GnuPP\\\\locale"
#define GPA_DATADIR "C:\\\\GnuPP\\\\GPA"
#define GPG_PROGRAM "C:\\\\GnuPP\\\\GnuPG\\\\gpg.exe"
EOF
8< ---- end of configure.pg ----------------------------------------
Please save this as a file `configure.pg' and give it the
"executable" bit:
chmod +x configure.pg
In this setup, the toolchain is installed in $HOME/usr, and GPA's
fallback directories (when a registry and PATH search did not lead
to a result) reside under "C:\GnuPP". Please do not use this script
blindly, but instead adapt it to match your system!
Now we are ready to configure and compile GPA:
./configure.pg
make
This will create `gpa.exe' in the subdirectory `src'.
The version of GPA which is distributed on the GnuPP CD of March
2002 (see http://www.gnupp.de) was cross-compiled from a GNU/Linux
system (Debian 2.2 "Potato") to mingw32/MS-Windows this way.
Please see the notes in GnuPG's README file about MS-Windows
registry entries when installing under MS-Windows.
In order to do anything useful with GPA you also need the
GNU Privacy Guard (GnuPG) - see http://www.gnupg.org.
Have fun!
