Original patches provided by Igor Todorovski <itodorov@ca.ibm.com> Reworked by Paul Smith <psmith@gnu.org>. Thanks to IBM for providing a test system. * NEWS: Announce support. * AUTHORS: Ditto. * README.zOS: Provide details on building GNU Make on z/OS. * build.sh (get_mk_var): z/OS sh has a strange bug which causes it to generate extra lines of output: rework the function to print output as we compute it instead of collecting it into a variable, which works around this bug. * src/makeint.h: Declare MK_OS_ZOS if we're building for z/OS. * src/arscan.c: Don't include <ar.h> on z/OS. * src/job.c: We can't change environ in ASCII mode on z/OS. * src/main.c: Ditto. Also we can't use pselect() on z/OS. * src/posixos.c: pselect() seems to hang on z/OS: don't use it. * tests/run_make_tests.pl: Handle different exit codes on z/OS. * tests/test_driver.pl: Preserve some special z/OS env.vars. Add special checks to output comparisons when on z/OS. * tests/scripts/features/archives: Don't validate names. Don't try to compile empty files as IBM compilers complain. * tests/scripts/features/shell_assignment: Fix octal value of #. * tests/scripts/features/temp_stdin: Don't print "term". * tests/scripts/functions/shell: Handle shell exit codes. * tests/scripts/targets/ONESHELL: Ditto. * tests/scripts/targets/POSIX: sh -x prints differently. * tests/scripts/variables/SHELL: Ditto.

GNU Make has been ported to z/OS, tested on z/OS V2R4.
|
|
|
|
|
|
PREREQUISITES
|
|
-------------
|
|
Building GNU Make requires certain tools be installed on your z/OS system.
|
|
These tools can be downloaded from: https://github.com/ZOSOpenTools
|
|
For detailed instructions on how to set up these tools, visit
|
|
https://zosopentools.github.io/meta/#/Guides/Pre-req
|
|
|
|
You will need curl, tar, and gzip to download and unpack the GNU Make release
|
|
package, but presumably you've already worked this out if you're reading this
|
|
document!
|
|
|
|
You will need the IBM C/C++ compiler. You can download a web deliverable
|
|
add-on feature to your XL C/C++ compiler here:
|
|
https://www-40.ibm.com/servers/resourcelink/svc00100.nsf/pages/xlCC++V241ForZOsV24
|
|
|
|
Alternatively, you can install and manage C/C++ for Open Enterprise Languages
|
|
on z/OS using RedHat OpenShift Container Platform and IBM Z and Cloud
|
|
Modernization Stack.
|
|
|
|
GNU Make has a dependency on the ZOSLIB library, which is documented here:
|
|
https://zosopentools.github.io/meta/#/Guides/Zoslib.
|
|
|
|
To obtain the latest release of zoslib, you can download it from here:
|
|
https://github.com/ZOSOpenTools/zoslibport/releases.
|
|
|
|
|
|
BUILDING
|
|
--------
|
|
If you are trying to build from a checked-out Git workspace, see README.git.
|
|
|
|
Before building GNU Make, you will need to ensure that the following
|
|
environment variables are set, to turn on z/OS enhanced ASCII support:
|
|
|
|
export _BPXK_AUTOCVT=ON
|
|
export _CEE_RUNOPTS="$_CEE_RUNOPTS FILETAG(AUTOCVT,AUTOTAG) POSIX(ON)"
|
|
export _TAG_REDIR_ERR=txt
|
|
export _TAG_REDIR_IN=txt
|
|
export _TAG_REDIR_OUT=txt
|
|
|
|
To ensure proper functioning of xlclang, set the following environment
|
|
variables before building:
|
|
|
|
export _CC_CCMODE=1
|
|
export _C89_CCMODE=1
|
|
export _CXX_CCMODE=1
|
|
|
|
Set PATH_TO_ZOSLIB to the location of your zoslib installation; e.g.:
|
|
|
|
PATH_TO_ZOSLIB=$HOME/zopen/prod/zoslib
|
|
|
|
Invoke ./configure as follows:
|
|
|
|
./configure \
|
|
CC=xlclang \
|
|
CPPFLAGS="-DNSIG=42 -D_XOPEN_SOURCE=600 -D_ALL_SOURCE -D_OPEN_SYS_FILE_EXT=1 -D_AE_BIMODAL=1 -D_ENHANCED_ASCII_EXT=0xFFFFFFF -DZOSLIB_OVERRIDE_CLIB=1" \
|
|
CFLAGS="-qascii -std=gnu11 -qnocsect -qenum=int -I$PATH_TO_ZOSLIB/include" \
|
|
LDFLAGS="-L$PATH_TO_ZOSLIB/lib" \
|
|
LIBS="-lzoslib $PATH_TO_ZOSLIB/lib/CXXRT64.x"
|
|
|
|
If you have an instance of make already available you can build with:
|
|
|
|
make
|
|
|
|
If not, you can build with:
|
|
|
|
./build.sh
|
|
|
|
|
|
TESTING
|
|
-------
|
|
To run the regression tests you'll need to install Perl and enable it.
|
|
Then you can run:
|
|
|
|
./make check
|
|
|
|
|
|
INSTALLING
|
|
----------
|
|
Copy the "make" program to wherever you want it to be installed, on your PATH.
