| 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 | 1.4 | configure has the following useful parameters: |
| 8 : | anton | 1.9 | --prefix=PREFIX install architecture-independent files in PREFIX |
| 9 : | [default: /usr/local] | ||
| 10 : | --exec-prefix=PREFIX install architecture-dependent files in PREFIX | ||
| 11 : | [default: same as prefix] | ||
| 12 : | anton | 1.8 | --enable-force-reg Use explicit register declarations if they appear in |
| 13 : | the machine.h file. This can cause a good speedup, | ||
| 14 : | but also incorrect code with some gcc versions on | ||
| 15 : | some processors (default disabled). | ||
| 16 : | --enable-direct-threaded Force direct threading. This may not work on | ||
| 17 : | some machines and may cause slowdown on others. | ||
| 18 : | (default processor-dependent) | ||
| 19 : | --enable-indirect-threaded Force indirect threading. This can cause a | ||
| 20 : | slowdown on some machines. | ||
| 21 : | (default processor-dependent) | ||
| 22 : | --with-debug specifies option -g to compile with debug info (default) | ||
| 23 : | --without-debug omits the -g switch and creates smaller images on | ||
| 24 : | machines where strip has problems with gcc style | ||
| 25 : | debugging informations. | ||
| 26 : | --help: tells you about other parameters. | ||
| 27 : | anton | 1.1 | |
| 28 : | anton | 1.9 | If you don't like the defaults for the installation directories, you |
| 29 : | should override them already during configure. E.g., if you want to | ||
| 30 : | install in the /gnu hierarchy instead of in the default /usr/local | ||
| 31 : | hirarchy, say | ||
| 32 : | anton | 1.5 | |
| 33 : | anton | 1.9 | ./configure --prefix=/gnu |
| 34 : | anton | 1.2 | |
| 35 : | anton | 1.9 | After, configuration, type |
| 36 : | |||
| 37 : | anton | 1.5 | make |
| 38 : | |||
| 39 : | If your make has trouble with the Makefile, "make gforth" might work. | ||
| 40 : | anton | 1.2 | |
| 41 : | anton | 1.9 | If your installed gcc isn't called "gcc" (e.g., called "gcc-2.6.1"), type |
| 42 : | anton | 1.1 | |
| 43 : | anton | 1.7 | make GCC=<whatever you call your gcc> |
| 44 : | pazsan | 1.4 | |
| 45 : | instead. | ||
| 46 : | anton | 1.6 | |
| 47 : | anton | 1.7 | Now you can check whether your shiny new Forth system works. Say |
| 48 : | |||
| 49 : | make test | ||
| 50 : | |||
| 51 : | anton | 1.6 | To make the documentation, type |
| 52 : | |||
| 53 : | make -k gforth.info gforth.ps html | ||
| 54 : | anton | 1.7 | |
| 55 : | If everything is allright, you may want to install gforth. Type | ||
| 56 : | |||
| 57 : | make install | ||
| 58 : | |||
| 59 : | anton | 1.9 | You have to make an entry in the info directory file manually. Also, |
| 60 : | you have to install gforth.ps and html yourself. | ||
| 61 : | anton | 1.10 | |
| 62 : | |||
| 63 : | A possible problem: | ||
| 64 : | |||
| 65 : | You need to read this only if you see a message like | ||
| 66 : | |||
| 67 : | "gforth: Cannot load nonrelocatable image (compiled for address 0x1234) at address 0x5678 | ||
| 68 : | The Gforth installer should look into the INSTALL file" | ||
| 69 : | |||
| 70 : | Gforth supports relocatable and fixed-address images. If you load | ||
| 71 : | normal Forth code and save the image, you get a fixed-address | ||
| 72 : | image. Producing a relocatable image is more difficult. | ||
| 73 : | |||
| 74 : | Consequently, Gforth has only a relocatable image of the kernel | ||
| 75 : | (kernal.fi), which is powerful enough to load the rest of | ||
| 76 : | Gforth. However, loading the rest takes a noticable amount of time. To | ||
| 77 : | avoid this delay on every startup,the installation procedure produces | ||
| 78 : | an image fixed at an address determined at the Gforth run that | ||
| 79 : | produced the image. This fixed-address image is loaded by default. On | ||
| 80 : | most OSs this works, because the first chunk of memory is always | ||
| 81 : | allocated at the same address. If the address changes, you get the | ||
| 82 : | message above. | ||
| 83 : | |||
| 84 : | An image address change can be caused by a change of the gforth | ||
| 85 : | executable, or by a change (upgrade) of the OS; in these cases you | ||
| 86 : | just have to rebuild and reinstall the fixed address image with | ||
| 87 : | |||
| 88 : | rm gforth.fi; make gforth.fi; make install | ||
| 89 : | |||
| 90 : | If you get such a message with a different address in place of the | ||
| 91 : | 0x5678 each time you try to start gforth, you cannot use fixed-address | ||
| 92 : | images on your OS. In this case, send us a message so that we start | ||
| 93 : | searching for a comfortable solution to this problem. In the | ||
| 94 : | meantime, start gforth with | ||
| 95 : | |||
| 96 : | gforth -i kernal.fi startup.fs | ||
| 97 : |
