PREREQUISITES
Using GCC:
Required
* gcc : GNU C compiler
* GNU binutils : A collection of binary tools
* GNU make : make
* sh : POSIX type shell
* GNU coreutils: Core utilities package (chmod, install, mkdir,
mv, rm, uname)
* perl : Practical Extraction and Report Language (perlpod)
Optional (depending on build targets):
* gettext : Framework to help GNU packages produce multi-
lingual messages.
* groff : GNU troff text formatting system.
* ghostscript : An interpreter for the PostScript language and
for PDF (ps2pdf)
* iconv : Character set conversion utility.
Using Watcom C:
Required
* Open Watcom : http://www.openwatcom.org/
* perl : Practical Extraction and Report Language (perlpod)
http://strawberryperl.com/
Using Microsoft Visual C++:
Required
* Visual C++ : You can get a free express version via this web page:
http://www.microsoft.com/visualstudio/eng/downloads#d-2010-express
* perl : Practical Extraction and Report Language (perlpod)
http://strawberryperl.com/
BASIC INSTALLATION
To build the program type:
make
To strip the executables:
make strip
To install:
make install
Clean:
make clean
Mostly clean.
The target mostlyclean will preserve the generated documentation files.
make mostlyclean
INSTALLATION NAMES
By default the 'install' target will install the program in
/usr/bin, the language files in /usr/share/locale
and the man page in /usr/share/man. You can specify an
installation prefix other than /usr by modifying the
'prefix' variable. An Example:
make prefix=$HOME clean all
make prefix=$HOME install
DEBUG
A debug enabled build can be made by adding DEBUG=1
to the make command. Example:
make clean install DEBUG=1
With debug enabled dos2unix will print extra information
and you can debug the source code in gdb.
NATIVE LANGUAGE SUPPORT
Native Language Support (NLS) is by default enabled.
To disable NLS add ENABLE_NLS=. Example:
make clean install ENABLE_NLS=
LARGE FILE SUPPORT
Large File Support (LFS) is by default enabled. This enables
the use of 64 bit file system interface on 32 bit systems.
This makes it possible to open files larger than 2GB on 32 bit
systems, provided the OS has LFS support builtin.
To disable LFS make the LFS variable empty. Example:
Disable LFS:
make clean install LFS=
UNICODE SUPPORT
Unicode UTF-16 support is by default enabled for Windows and Unix. To
disable make the UCS variable (Universal Character Set) empty.
Disable Unicode:
make clean install UCS=
Unicode UTF-16 is not supported by the DOS and OS/2 versions.
ESPERANTO X-NOTATION
For systems that don't support the Unicode or Latin-3 character set,
Esperanto messages in ASCII x-notation format can be selected. Add
EO_XNOTATION=1 to the make command-line. It will change the format of the
normal dos2unix 'eo' locale from Unicode to ASCII x-notation.
make clean install EO_XNOTATION=1
DOCUMENTATION
Manual pages are generated from Perl POD files.
The manual pages in text and html format are by default only
created in English language. To create text and html manuals
for other languages type:
make txt
make html
Once the manuals in non-English languages have been created,
they will also be installed under share/doc/ when you type
'make install'
Creation of non-English manuals in text or html format require
an installation of iconv.
Manuals in PDF format are by default not created.
To create manuals in PDF format type:
make pdf
PDF generation requires GhostScript to be installed.
WINDOWS PORT
To compile a version for Windows, get the Mingw compiler
<http://www.mingw.org>, and use makefile mingw.mak:
make -f mingw.mak clean
make -f mingw.mak
make -f mingw.mak strip
make -f mingw.mak install
Or use Open Watcom and type:
wmake -f wccwin32.mak clean
wmake -f wccwin32.mak
wmake -f wccwin32.mak install
Or use Microsoft Visual C++ and type:
nmake /f vc.mak clean
nmake /f vc.mak
nmake /f vc.mak install
The win32 binaries built with MinGW32 are packed with a patched version of
MinGW's libintl-8.dll that has builtin support for relocation. See also
http://waterlan.home.xs4all.nl/libintl.html and
http://sourceforge.net/tracker/?func=detail&atid=302435&aid=3003879&group_id=2435
WINDOWS 64 BIT PORT
To compile a version for Windows, get the Mingw-w64 compiler
<http://mingw-w64.sourceforge.net>, and use makefile mingw64.mak:
make -f mingw64.mak clean
make -f mingw64.mak
make -f mingw64.mak strip
make -f mingw64.mak install
DOS PORT, 32 BIT
To compile a version for DOS, get the DJGPP compiler
<http://www.delorie.com/djgpp/>, and use makefile djgpp.mak:
make -f djgpp.mak clean
make -f djgpp.mak
make -f djgpp.mak strip
make -f djgpp.mak install
Or use Open Watcom
wmake -f wccdos32.mak clean
wmake -f wccdos32.mak
wmake -f wccdos32.mak install
DOS PORT, 16 BIT
To compile a version for DOS, use the Borland C compiler 3.1 or 4.0,
and use makefile bcc.mak:
make -f bcc.mak clean
make -f bcc.mak
Or use Open Watcom
wmake -f wccdos16.mak clean
wmake -f wccdos16.mak
wmake -f wccdos16.mak install
OS/2 PORT
Using EMX
make -f emx.mak clean
make -f emx.mak
make -f emx.mak strip
make -f emx.mak install
Open Watcom
wmake -f wccos2.mak clean
wmake -f wccos2.mak
wmake -f wccos2.mak install
