| ad5a63fe | 1 | microperl is supposed to be a really minimal perl, even more |
| 12ae5dfc JH |
2 | minimal than miniperl. No Configure is needed to build microperl, |
| 3 | on the other hand this means that interfaces between Perl and your | |
| 4 | operating system are left very -- minimal. | |
| 5 | ||
| 6 | All this is experimental. If you don't know what to do with microperl | |
| a83b6f46 JH |
7 | you probably shouldn't. Do not report bugs in microperl; fix the bugs. |
| 8 | ||
| 75bd9dfb | 9 | We assume ANSI C89 plus the following: |
| 2f42fcb0 JH |
10 | - <stdlib.h> |
| 11 | - rename() | |
| 12 | - opendir(), readdir(), closedir() (via dirent.h) | |
| 535ceeb0 | 13 | - memchr(), memcmp(), memcpy() (via string.h) |
| 2f42fcb0 JH |
14 | - (a safe) putenv() (via stdlib.h) |
| 15 | - strtoul() (via stdlib.h) | |
| 16 | (grep for 'define' in uconfig.sh.) | |
| 17 | Also, Perl times() is defined to always return zeroes. | |

19 | If you are still reading this and you are itching to try out microperl: |
| 20 | ||
| 21 | make -f Makefile.micro | |
| 22 | ||
| ad5a63fe | 23 | If you make changes to uconfig.sh, run |
| a83b6f46 | 24 | |
| ad5a63fe | 25 | make -f Makefile.micro regen_uconfig |
| 12ae5dfc | 26 | |
| 2eacba2f JH |
27 | to regenerate uconfig.h. If your compilation platform is not 32-bit |
| 28 | little-endian (like x86), you might want to try | |
| 29 | ||
| 30 | make -f Makefile.micro patch_uconfig | |
| 31 | ||
| 32 | *before* the "make -f Makefile.micro". This tries to minimally patch | |
| 33 | the uconfig.sh using your *current* Perl so that your microperl has | |
| 34 | the correct basic types and sizes and byteorder. | |
