Port of GNU make to OS/2.
|
||
|
||
Features of GNU make that do not work under OS/2:
|
||
- remote job execution
|
||
- dynamic load balancing
|
||
|
||
|
||
Special features of the OS/2 version:
|
||
|
||
Due to the fact that some people might want to use sh syntax in
|
||
Makefiles while others might want to use OS/2's native shell cmd.exe,
|
||
GNU make supports both shell types. The following list defines the order
|
||
that is used to determine the shell:
|
||
|
||
1. The shell specified by the environment variable MAKESHELL.
|
||
2. The shell specified by the SHELL variable within a Makefile. Like
|
||
Unix, SHELL is NOT taken from the environment.
|
||
3. The shell specified by the COMSPEC environment variable.
|
||
4. The shell specified by the OS2_SHELL environment variable.
|
||
5. If none of the above is defined /bin/sh is used as default. This
|
||
happens e.g. in the make testsuite.
|
||
|
||
Note: - Points 3 and 4 can be turned off at compile time by adding
|
||
-DNO_CMD_DEFAULT to the CPPFLAGS.
|
||
- DOS support is not tested for EMX and therefore might not work.
|
||
- The UNIXROOT environment variable is supported to find /bin/sh
|
||
if it is not on the current drive.
|
||
|
||
|
||
COMPILATION OF GNU MAKE FOR OS/2:
|
||
|
||
I. ***** SPECIAL OPTIONS *****
|
||
|
||
- At compile time you can turn off that cmd is used as default shell
|
||
(but only /bin/sh). Simply set CPPFLAGS="-DNO_CMD_DEFAULT" and make
|
||
will not use cmd unless you cause it to do so by setting MAKESHELL to
|
||
cmd or by specifying SHELL=cmd in your Makefile.
|
||
|
||
- At compile time you can set CPPFLAGS="-DNO_CHDIR2" to turn off that
|
||
GNU make prints drive letters. This is necessary if you want to run
|
||
the testsuite.
|
||
|
||
|
||
II. ***** REQUIREMENTS FOR THE COMPILATION *****
|
||
|
||
A standard Unix like build environment:
|
||
|
||
- sh compatible shell (ksh, bash, ash, but tested only with pdksh 5.2.14
|
||
release 2)
|
||
If you use pdksh it is recommended to update to 5.2.14 release 2. Older
|
||
versions may not work! You can get this version at
|
||
http://www.math.ohio-state.edu/~ilya/software/os2/pdksh-5.2.14-bin-2.zip
|
||
- GNU file utilities (make sure that install.exe from the file utilities
|
||
is in front of your PATH before X:\OS2\INSTALL\INSTALL.EXE. I recommend
|
||
also to change the filename to ginstall.exe instead of install.exe
|
||
to avoid confusion with X:\OS2\INSTALL\INSTALL.EXE)
|
||
- GNU shell utilities
|
||
- GNU text utilities
|
||
- gawk
|
||
- grep
|
||
- sed
|
||
- GNU make 3.79.1 (special OS/2 patched version) or higher
|
||
- perl 5.005 or higher
|
||
- GNU texinfo (you can use 3.1 (gnuinfo.zip), but I recommend 4.0)
|
||
|
||
If you want to recreate the configuration files (developers only!)
|
||
you need also: GNU m4 1.4, autoconf 2.59, automake 1.9.6 (or compatible)
|
||
|
||
|
||
III. ***** COMPILATION AND INSTALLATION *****
|
||
|
||
a) ** Developers only - Everyone else should skip this section **
|
||
To recreate the configuration files use:
|
||
|
||
export EMXSHELL=ksh
|
||
aclocal -I config
|
||
automake
|
||
autoconf
|
||
autoheader
|
||
|
||
|
||
b) Installation into x:/usr
|
||
|
||
Note: Although it is possible to compile make using "./configure",
|
||
"make", "make install" this is not recommended. In particular,
|
||
you must ALWAYS use LDFLAGS="-Zstack 0x6000" because the default
|
||
stack size is far to small and make will not work properly!
|
||
|
||
Recommended environment variables and installation options:
|
||
|
||
export ac_executable_extensions=".exe"
|
||
export CPPFLAGS="-D__ST_MT_ERRNO__"
|
||
export CFLAGS="-O2 -Zomf -Zmt"
|
||
export LDFLAGS="-Zcrtdll -Zlinker /exepack:2 -Zlinker /pm:vio -Zstack 0x6000"
|
||
export RANLIB="echo"
|
||
./configure --prefix=x:/usr --infodir=x:/usr/share/info --mandir=x:/usr/share/man --without-included-gettext
|
||
make AR=emxomfar
|
||
make install
|
||
|
||
Note: If you use gcc 2.9.x I recommend to set also LIBS="-lgcc"
|
||
|
||
Note: You can add -DNO_CMD_DEFAULT and -DNO_CHDIR2 to CPPFLAGS.
|
||
See section I. for details.
|
||
|
||
|
||
IV. ***** NLS support *****
|
||
|
||
GNU make has NLS (National Language Support), with the following
|
||
caveats:
|
||
|
||
a) It will only work with GNU gettext, and
|
||
b) GNU gettext support is not included in the GNU make package.
|
||
|
||
Therefore, if you wish to enable the internationalization features of
|
||
GNU make you must install GNU gettext on your system before configuring
|
||
GNU make.
|
||
|
||
You can choose the languages to be installed. To install support for
|
||
English, German and French only enter:
|
||
|
||
export LINGUAS="en de fr"
|
||
|
||
If you don't specify LINGUAS all languages are installed.
|
||
|
||
If you don't want NLS support (English only) use the option
|
||
--disable-nls for the configure script. Note if GNU gettext is not
|
||
installed then NLS will not be enabled regardless of this flag.
|
||
|
||
|
||
V. ***** Running the make test suite *****
|
||
|
||
To run the included make test suite you have to set
|
||
|
||
CPPFLAGS="-D__ST_MT_ERRNO__ -DNO_CMD_DEFAULT -DNO_CHDIR2"
|
||
|
||
before you compile make. This is due to some restrictions of the
|
||
testsuite itself. -DNO_CMD_DEFAULT causes make to use /bin/sh as default
|
||
shell in every case. Normally you could simply set MAKESHELL="/bin/sh"
|
||
to do this but the testsuite ignores the environment. -DNO_CHDIR2 causes
|
||
make not to use drive letters for directory names (i.e. _chdir2() and
|
||
_getcwd2() are NOT used). The testsuite interpretes the whole output of
|
||
make, especially statements like make[1]: Entering directory
|
||
`C:/somewhere/make-3.79.1/tests' where the testsuite does not expect the
|
||
drive letter. This would be interpreted as an error even if there is
|
||
none.
|
||
|
||
To run the testsuite do the following:
|
||
|
||
export CPPFLAGS="-D__ST_MT_ERRNO__ -DNO_CMD_DEFAULT -DNO_CHDIR2"
|
||
export CFLAGS="-Zomf -O2 -Zmt"
|
||
export LDFLAGS="-Zcrtdll -s -Zlinker /exepack:2 -Zlinker /pm:vio -Zstack 0x6000"
|
||
export RANLIB="echo"
|
||
./configure --prefix=x:/usr --disable-nls
|
||
make AR=emxomfar
|
||
make check
|
||
|
||
All tests should work fine with the exception of one of the "INCLUDE_DIRS"
|
||
tests which will fail if your /usr/include directory is on a drive different
|
||
from the make source tree.
