| | 1 | microperl is supposed to be a really minimal perl, even more |
| | 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 |
| | 7 | you probably shouldn't. Do not report bugs in microperl; fix the bugs. |
| | 8 | |
| | 9 | We assume ANSI C89 plus the following: |
| | 10 | - <stdlib.h> |
| | 11 | - rename() |
| | 12 | - opendir(), readdir(), closedir() (via dirent.h) |
| | 13 | - memchr(), memcmp(), memcpy() (via string.h) |
| | 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. |
| | 18 | |
| | 19 | If you are still reading this and you are itching to try out microperl: |
| | 20 | |
| | 21 | make -f Makefile.micro |
| | 22 | |
| | 23 | If you make changes to uconfig.sh, run |
| | 24 | |
| | 25 | make -f Makefile.micro regen_uconfig |
| | 26 | |
| | 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. |
