| 1 : | anton | 1.7 | You need gcc version 2.0 or later to compile gforth. |
| 2 : | anton | 1.1 | |
| 3 : | anton | 1.5 | First, type |
| 4 : | anton | 1.3 | |
| 5 : | anton | 1.8 | ./configure |
| 6 : | anton | 1.1 | |
| 7 : | pazsan | 1.14 | or better |
| 8 : | |||
| 9 : | CC=gcc ./configure | ||
| 10 : | |||
| 11 : | or however your gcc is called; because configure needs cc to find out some | ||
| 12 : | parameters, and there may be differences in what is obtained from gcc and | ||
| 13 : | from ghe default cc. | ||
| 14 : | |||
| 15 : | pazsan | 1.4 | configure has the following useful parameters: |
| 16 : | anton | 1.9 | --prefix=PREFIX install architecture-independent files in PREFIX |
| 17 : | [default: /usr/local] | ||
| 18 : | --exec-prefix=PREFIX install architecture-dependent files in PREFIX | ||
| 19 : | [default: same as prefix] | ||
| 20 : | anton | 1.8 | --enable-force-reg Use explicit register declarations if they appear in |
| 21 : | the machine.h file. This can cause a good speedup, | ||
| 22 : | but also incorrect code with some gcc versions on | ||
| 23 : | some processors (default disabled). | ||
| 24 : | --enable-direct-threaded Force direct threading. This may not work on | ||
| 25 : | some machines and may cause slowdown on others. | ||
| 26 : | (default processor-dependent) | ||
| 27 : | --enable-indirect-threaded Force indirect threading. This can cause a | ||
| 28 : | slowdown on some machines. | ||
| 29 : | (default processor-dependent) | ||
| 30 : | --with-debug specifies option -g to compile with debug info (default) | ||
| 31 : | --without-debug omits the -g switch and creates smaller images on | ||
| 32 : | machines where strip has problems with gcc style | ||
| 33 : | debugging informations. | ||
| 34 : | --help: tells you about other parameters. | ||
| 35 : | anton | 1.1 | |
| 36 : | anton | 1.9 | If you don't like the defaults for the installation directories, you |
| 37 : | should override them already during configure. E.g., if you want to | ||
| 38 : | install in the /gnu hierarchy instead of in the default /usr/local | ||
| 39 : | hirarchy, say | ||
| 40 : | anton | 1.5 | |
| 41 : | anton | 1.9 | ./configure --prefix=/gnu |
| 42 : | anton | 1.2 | |
| 43 : | anton | 1.9 | After, configuration, type |
| 44 : | |||
| 45 : | anton | 1.5 | make |
| 46 : | |||
| 47 : | If your make has trouble with the Makefile, "make gforth" might work. | ||
| 48 : | anton | 1.2 | |
| 49 : | anton | 1.9 | If your installed gcc isn't called "gcc" (e.g., called "gcc-2.6.1"), type |
| 50 : | anton | 1.1 | |
| 51 : | anton | 1.7 | make GCC=<whatever you call your gcc> |
| 52 : | pazsan | 1.4 | |
| 53 : | instead. | ||
| 54 : | anton | 1.6 | |
| 55 : | anton | 1.7 | Now you can check whether your shiny new Forth system works. Say |
| 56 : | |||
| 57 : | make test | ||
| 58 : | |||
| 59 : | anton | 1.12 | You can run some benchmarks with |
| 60 : | anton | 1.6 | |
| 61 : | anton | 1.12 | make bench |
| 62 : | |||
| 63 : | and compare them with the results in Benchres and in the manual. | ||
| 64 : | anton | 1.7 | |
| 65 : | anton | 1.13 | If everything is all right, you may want to install gforth. Type |
| 66 : | anton | 1.7 | |
| 67 : | make install | ||
| 68 : | |||
| 69 : | anton | 1.12 | You have to make an entry in the info directory file manually. |
| 70 : | |||
| 71 : | For paper documentation, print gforth.ps (a Postscript file (300dpi | ||
| 72 : | fonts, i.e., it works, but does not produce best quality on better | ||
| 73 : | printers)), or say | ||
| 74 : | |||
| 75 : | make gforth.dvi | ||
| 76 : | |||
| 77 : | and print the resulting file gforth.dvi. You can also get the | ||
| 78 : | documentation in HTML format by typing | ||
| 79 : | |||
| 80 : | make html | ||
| 81 : | |||
| 82 : | anton | 1.13 | |
| 83 : | Preloading installation-specific code | ||
| 84 : | |||
| 85 : | If you want to have some installation-specific files loaded when | ||
| 86 : | Gforth starts (e.g., an assembler for your processor), put commands | ||
| 87 : | for loading them into /usr/local/share/gforth/site-forth/site-init.fs | ||
| 88 : | (if the commands work for all architectures) or | ||
| 89 : | /usr/local/lib/gforth/site-forth/site-init.fs (for | ||
| 90 : | architecture-specific commands); | ||
| 91 : | /usr/local/lib/gforth/site-forth/site-init.fs takes precedence if both | ||
| 92 : | files are present (unless you change the search path). The file names | ||
| 93 : | given above are the defaults; if you have changed the prefix, you have | ||
| 94 : | to replace "/usr/local" in these names with your prefix. | ||
| 95 : | |||
| 96 : | By default, the installation procedure creates an empty | ||
| 97 : | /usr/local/share/gforth/site-forth/site-init.fs if there is no such | ||
| 98 : | file. | ||
| 99 : | |||
| 100 : | If you change the site-init.fs file, you should run "make install" | ||
| 101 : | again for the changes to take effect (Actually, the part of "make | ||
| 102 : | install" starting with "rm gforth.fi" is sufficient). | ||
| 103 : | |||
| 104 : | |||
| 105 : | anton | 1.12 | Multiple Versions and Deinstallation |
| 106 : | |||
| 107 : | Several versions of Gforth can be installed and used at the same | ||
| 108 : | time. Version `foo' can be invoked with `gforth-foo'. We recommend to | ||
| 109 : | keep the old version for some time after a new one has been installed. | ||
| 110 : | anton | 1.10 | |
| 111 : | anton | 1.12 | You can deinstall this version of Gforth with 'make uninstall' and |
| 112 : | version foo with 'make uninstall VERSION=foo'. 'make uninstall' also | ||
| 113 : | tells you how to uninstall Gforth completely. | ||
| 114 : | anton | 1.13 | |
| 115 : | anton | 1.10 | |
| 116 : | anton | 1.12 | A Possible Problem |
| 117 : | anton | 1.10 | |
| 118 : | You need to read this only if you see a message like | ||
| 119 : | |||
| 120 : | "gforth: Cannot load nonrelocatable image (compiled for address 0x1234) at address 0x5678 | ||
| 121 : | The Gforth installer should look into the INSTALL file" | ||
| 122 : | |||
| 123 : | anton | 1.11 | Gforth supports both relocatable and fixed-address images. If you load |
| 124 : | anton | 1.10 | normal Forth code and save the image, you get a fixed-address |
| 125 : | image. Producing a relocatable image is more difficult. | ||
| 126 : | |||
| 127 : | anton | 1.11 | Therefore, Gforth has only a relocatable image of the kernel |
| 128 : | anton | 1.10 | (kernal.fi), which is powerful enough to load the rest of |
| 129 : | Gforth. However, loading the rest takes a noticable amount of time. To | ||
| 130 : | anton | 1.11 | avoid this delay (which would occur on every startup), the |
| 131 : | installation procedure produces an image fixed at an address | ||
| 132 : | determined at the Gforth run that produced the image. This | ||
| 133 : | fixed-address image is loaded by default. On most OSs this works, | ||
| 134 : | because the first chunk of memory is always allocated at the same | ||
| 135 : | address. If the address changes, you get the message above. | ||
| 136 : | anton | 1.10 | |
| 137 : | An image address change can be caused by a change of the gforth | ||
| 138 : | executable, or by a change (upgrade) of the OS; in these cases you | ||
| 139 : | just have to rebuild and reinstall the fixed address image with | ||
| 140 : | |||
| 141 : | rm gforth.fi; make gforth.fi; make install | ||
| 142 : | |||
| 143 : | If you get such a message with a different address in place of the | ||
| 144 : | 0x5678 each time you try to start gforth, you cannot use fixed-address | ||
| 145 : | images on your OS. In this case, send us a message so that we start | ||
| 146 : | searching for a comfortable solution to this problem. In the | ||
| 147 : | meantime, start gforth with | ||
| 148 : | |||
| 149 : | gforth -i kernal.fi startup.fs | ||
| 150 : |
