 |
|
Hi all,
I see that some programs don't have .IRX files but load modules anyway.
I deduce they are included in the .ELF file.
I saw that in the Altimit project, but when reading source code, i don't know how it loads module.
Can someone tell me how does it works ?
thx |

1) produce a .s file out of the irx file:
| Code: | | bin2s my_module.irx my_module.s my_module |
2) declare the module into your C code:
| Code: | extern unsigned char my_module[];
extern unsigned int size_my_module; |
3) load the module into your C code:
| Code: | int ret;
SifExecModuleBuffer(my_module, size_my_module, 0, NULL, &ret); |
4) don't forget to compile the .s file with your C code:
| Code: | | ee-gcc -o final_binary.elf my_code.c my_module.s |

ok thanks a lot for your quick and very precise answer.
However i still have a problem.
I downloaded Altimit 0.1 (src and bin) ans when i compile sources, i don't have the same size as the original ELF (this last works)
Mine is 328 Ko (uncompressed) whereas the original is 1 Mb
What am i doing wrong |

yours might be stripped from symbols, the distributed 0.1 elf might not, wich would make debugging easier for tombola.
