1 | microperl is supposed to be a really minimal perl, even more |
| 12ae5dfc |
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 |
7 | you probably shouldn't. Do not report bugs in microperl; fix the bugs. |

9 | We assume ANSI C89 plus the following: |
| 2f42fcb0 |
10 | - <stdlib.h> |
| 11 | - rename() |
| 12 | - opendir(), readdir(), closedir() (via dirent.h) |
| 535ceeb0 |
13 | - memchr(), memcmp(), memcpy() (via string.h) |
| 2f42fcb0 |
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 |
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. |
