IMPORTANT: Please see the section at the bottom of this file for some important information on Makefiles used in calc. ################################################################### # IMPORTANT: DO NOT use make in parallel mode!!! # ################################################################### # Unfortunately due to the complex dependency issues between # # Makefile, Makefile.ship and custom/Makefile, parallel make # # is NOT recommended. Sorry (tm Canada) :) # ################################################################### Installing calc from the bzip2-ed tarball: 4 easy steps: (0) If your platform supports i686 RPMs, you may want to go to: https://github.com/lcn2/calc/releases Open up the 'Assets' tag below a given release and download these RPMs: * calc*.i686.rpm - all that is needed if you just want to use calc * calc-devel-*.i686.rpm - calc *.h header and *.a lib files for use in other programs * calc.*.src.rpm - calc source via a SRPM package Alternately to the above github link, you might try looking at the RPMs under: http://www.isthe.com/chongo/src/calc/ =-= The following 4 steps apply to calc source tree that comes from either: bunzip2 -c calc-*.tar.bz2 | tar -xvf - or from: rpm -ivh calc-*.src.rpm cd /var/tmp bunzip2 -c /usr/src/redhat/SOURCES/calc-*.tar.bz2 | tar -xvf - 4 steps: (1) Look at the makefile, and adjust it to suit your needs. The top level Makefile and the custom/Makefile require a modern Make (such as gmake) or an equivalently advanced make. On many targets, the default make is sufficient. On FreeBSD for example, probably want to use gmake instead of make. Some report that under macOS, one has to declare the target to be Darwin. So for macOS, one might have to do: # for macOS users only, force the target to be Darwin # make target=Darwin clobber make target=Darwin all make target=Darwin chk make target=Darwin install If your target system does not have a modern Makefile (such as gmake), then you should try using the Makefile.simple and custom/Makefile.simple files: mv Makefile Makefile.gmake cp Makefile.simple Makefile mv custom/Makefile custom/Makefile.gmake cp custom/Makefile.simple custom/Makefile The Makefile, as shipped, is suitable for installation under Linux and Un*x-like environments. For the most part, the default values should work. If in doubt, follow the 'When in doubt' suggestion. If you are using a modern make (such as gmake), you may override any values set in the Makefile by adding them to Makefile.local using the := directive. For example: HAVE_STRING_H:= YES HAVE_TIMES_H:= YES SED:= /usr/local/bin/nsed !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! ! If you are building under Windows or a Windows-like environment ! ! (such as Cygwin or DJGPP), read the README.WINDOWS file. ! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! You should determine if these Makefile variables are reasonable: INCDIR Where the system include (.h) files are kept. BINDIR Where to install calc binary files. LIBDIR Where to install calc link library (*.a) files. CALC_SHAREDIR Where to install calc help, .cal, startup, and config files. You may want to change the default installation locations for these values, which are based on the 4 values listed above: HELPDIR where the help directory is installed CALC_INCDIR where the calc include files are installed CUSTOMCALDIR where custom *.cal files are installed CUSTOMHELPDIR where custom help files are installed CUSTOMINCDIR where custom .h files are installed SCRIPTDIR where calc shell scripts are installed If you want to install calc files under a top level directory, then set the T value: The calc install is performed under ${T}, the calc build is performed under /. The purpose for ${T} is to allow someone to install calc somewhere other than into the system area. For example, if: BINDIR= /usr/bin LIBDIR= /usr/lib CALC_SHAREDIR= /usr/share/calc and if: T= /var/tmp/testing Then the installation locations will be: calc binary files: /var/tmp/testing/usr/bin calc link library: /var/tmp/testing/usr/lib calc help, .cal ...: /var/tmp/testing/usr/share/calc ... etc ... /var/tmp/testing/... If ${T} is empty, calc is installed under /, which is the same top of tree for which it was built. If ${T} is non-empty, then calc is installed under ${T}, as if one had to chroot under ${T} for calc to operate. Look for the section that starts: ################ # compiler set # ################ Select a compiler set by commenting in the appropriate set of cc options. As shipped the Makefile assumes a gcc-like environment such as Linux. If a more appropriate cc set if found below, comment out the Linux set and comment in that set or edit the gcc set or the common cc set as needed. You may want to change these Makefile variables from their defaults: RANLIB You may or may not need RANLIB when building libraries. As shipped the Makefile assumes RANLIB is needed. Comment the in/out the RANLIB value if ranlib does not work or does not exist. CALCPAGER You may want to change the default pager used by calc. As shipped the Makefile assumes 'more'. On your system you may find 'less' to be a better pager. DEBUG Some compilers (to put it mildly) have bugs. Sometimes the DEBUG Makefile variable causes the compiler / optimizer to produce bad code. Other compilers do just fine. If possible try to use DEBUG=-O3 -g3 (maximum optimization and debug symbols). If the calc test fails (see step 3), try lowering either the -O value and/or the -g3. Also try using -Osomething without -g. Adjust other Makefile variables as needed. (2) build calc: The top level Makefile and the custom/Makefile require a GNU Make (such as gmake) or an equivalently advanced make. On many targets, the default make is sufficient. On FreeBSD for example, one must use gmake instead of make. If your target system does not have GNU Make (or equivalent), then you should try using the Makefile.simple and custom/Makefile.simple files: mv Makefile Makefile.gmake cp Makefile.simple Makefile mv custom/Makefile custom/Makefile.gmake cp custom/Makefile.simple custom/Makefile make all ==> We are interested in any compiler warnings (and errors) that you may find. See the BUGS file if you find any compiler warning or errors. NOTE: You can force calc to build with only static libs: make clobber make calc-static-only BLD_TYPE=calc-static-only or force calc to build with only dynamic libs: make clobber make calc-dynamic-only BLD_TYPE=calc-dynamic-only (3) test calc: make check NOTE: For a quiet check which only prints if something goes wrong: make chk (4) install calc: make install We suggest that you might want to read the README.FIRST file and look at the calc help subsystem. See also the README.md file. In general, if you run into problems, read the BUGS file and follow the instructions. =-= On calc Makefiles: How to tell the origin of of a Makefile: The "# SRC: ... - ..." comment line near the top of the file indicates the origin of this file. In each segment below, we indicate what the SRC comment like will read. SHELL= ... On some systems, /bin/sh is a rather reduced shell with deprecated behavior. If your system has a up to date, bash shell, then you may wish to edit the Makefile to use: SHELL= /bin/bash On some systems such as macOS, the bash shell is very far behind to the point where is cannot be depended on. On such systems, the sh may be a much better alternative shell for this Makefile to use: SHELL= /bin/sh Makefile.local # SRC: Makefile.local - tweaks to the top level Makefile Between releases, Makefile.local at the top of the master branch will contain how we typically build calc and test calc (FYI: we normally enable things such as -Werror -Wextra -pedantic). When we push out a release, Makefile.local will be stripped of non-comment lines. Thus, releases of calc, and, released "calc*.src.rpm" files and the source tarballs, will have a Makefile.local with only comments. If the Makefile is not suitable for you (say because you fetch it from the top of the master branch between releases), then you may wish to remove all non-comment lines. I.e., lines that do not start with the # character. This Makefile.local assumes you have a modern make command such as the GNU make. See Makefile.simple comment below if you do not have such a modern make command. In the calc GitHub repo, Makefile is the calc build environment and Makefile.ship is the top level Makefile: https://github.com/lcn2/calc Makefile # SRC: Makefile.ship - top level Makefile This is the main top level Makefile. In calc packages such as RPMs, and the tar.bz2 source tarball, Makefile.ship has been moved into Makefile. In the calc GitHub repo, Makefile is the calc build environment and Makefile.ship is the top level Makefile: https://github.com/lcn2/calc The Makefile.simple rule of Makefile.ship, when forming the Makefile.simple file, removes lines from Makefile.ship between pairs of '#if 0' AND '#endif': #if 0 lines removed when forming Makefile.simple ... lines removed when forming Makefile.simple #endif The '#if 0' AND '#endif' MUST be at the start of the line. Any text after the '#if 0' OR '#endif' is ignored. While they may look like a CPP directives, they are not. The inline awk script of the Makefile.simple rule does NOT allow them to nest: #if 0 /* DO NOT DO THIS */ lines removed when forming Makefile.simple ... #if 0 /* DO NOT DO THIS */ ... #endif /* DO NOT DO THIS */ ... #endif /* DO NOT DO THIS */ The custom/Makefile rule of Makefile.ship is used to form the custom/Makefile. In particular the Makefile.ship lines: # start of host target cut ... these go between custom/Makefile.head and custom/Makefile.tail # end of host target cut Makefile.simple # SRC: non-GNU Makefile via make -f Makefile.ship Makefile.simple This is a non-GNU or simple Makefile designed for environments that do not have a modern make command. If you have a Makefile.simple file, use these commands to form a Makefile: if [ -f Makefile ]; then mv -f Makefile Makefile.orig; fi cp Makefile.simple Makefile The Makefile.simple rule from Makefile.ship is used to construct this file from the contents of Makefile.ship. In calc packages such as RPMs, and the tar.bz2 source the Makefile.simple exists. In the calc GitHub repo: https://github.com/lcn2/calc this file does NOT exist and must be made via the Makefile.simple make rule. Therefore, non-GNU and simple make commands are NOT supported by the calc GitHub repo master branch. Instead, you need to extract Makefile.simple from one of the calc tar.bz2 source tarball source from a calc source mirror: http://www.isthe.com/chongo/tech/comp/calc/calc-mirror.html custom/Makefile.head # SRC: custom/Makefile.head This file forms the top part of the custom/Makefile. custom/Makefile.tail # SRC: custom/Makefile.tail This file forms the bottom part of the custom/Makefile. custom/Makefile # SRC: Makefile via make -f Makefile custom/Makefile This is the custom directory Makefile. The custom/Makefile rule of Makefile.ship is used to form the custom/Makefile. In particular the Makefile.ship lines: # start of host target cut ... these go in between custom/Makefile.head and custom/Makefile.tail # end of host target cut NOTE: The clobber rule does not remove this file. - XXX custom/Makefile.simple # SRC: non-GNU Makefile via make -f Makefile custom/Makefile.simple This is a non-GNU or simple Makefile for the custom directory that is designed for environments that do not have a modern make command. In calc packages such as RPMs, and the tar.bz2 source the Makefile.simple exists. In the calc GitHub repo: https://github.com/lcn2/calc this file does NOT exist and must be made via the custom/Makefile.simple make rule. Therefore, non-GNU and simple make commands are NOT supported by the calc GitHub repo master branch. Instead, you need to extract custom/Makefile.simple from one of the calc tar.bz2 source tarball source from a calc source mirror: http://www.isthe.com/chongo/tech/comp/calc/calc-mirror.html cal/Makefile # SRC: cal/Makefile The Makefile for the cal sub-directory. cscript/Makefile # SRC: cscript/Makefile The Makefile for the cscript sub-directory. help/Makefile # SRC: help/Makefile The Makefile for the help sub-directory. ## Copyright (C) 1999-2007,2021 Landon Curt Noll ## ## Calc is open software; you can redistribute it and/or modify it under ## the terms of the version 2.1 of the GNU Lesser General Public License ## as published by the Free Software Foundation. ## ## Calc is distributed in the hope that it will be useful, but WITHOUT ## ANY WARRANTY; without even the implied warranty of MERCHANTABILITY ## or FITNESS FOR A PARTICULAR PURPOSE.
