| # 20:38:47 |
y_morin |
xvilka: COFF? What's that? |
| # 20:39:01 |
y_morin |
xvilka: you mean, with crosstool-NG ? |
| # 20:42:26 |
xvilka |
yep |
| # 20:42:54 |
xvilka |
not elf, but coff |
| # 20:46:48 |
y_morin |
xvilka: probably not. |
| # 20:47:18 |
y_morin |
xvilka: COFF is primarily used fos Windows (with the PE extensions, PE/COFF). Other uses are rare nowadays, althgough EFI does use it. |
| # 20:48:06 |
y_morin |
xvilka: as noone, not even myself, has had interest in this, there is not support for this in crosstool-NG |
| # 20:48:22 |
y_morin |
xvilka: but if you need it, and you can make it work, patches welcome! ;-) |
| # 20:50:47 |
xvilka |
yep. where i can start to see/try/etc for adding coff support? |
| # 20:51:20 |
xvilka |
gcc.sh and binutils.sh? is this enough? |
| # 20:52:09 |
y_morin |
xvilka: starting by adding COFF to the list in: config/binutils.in |
| # 20:52:31 |
y_morin |
xvilka: then choose an archiotecture for which COFF makes sense (eg. x86?) |
| # 20:52:45 |
xvilka |
ok. written that |
| # 20:53:04 |
xvilka |
s/written/recorded :) |
| # 20:53:34 |
y_morin |
xvilka: then change the 'system' part of the tuple to be 'coff' instead of 'elf'. Eg. in scripts/build/arch/x86.sh |
| # 20:53:51 |
y_morin |
xvilka: it's variable CT_TARGET_SYS |
| # 20:54:39 |
y_morin |
xvilka: then, provided the tools (gcc+binutils) are not too dumb, they should recognise tuples matching *-coff |
| # 20:54:52 |
xvilka |
cool. thx. will try |
| # 20:56:23 |
y_morin |
xvilka: you may want to use 'ecoff' instead. |
| # 20:57:10 |
y_morin |
xvilka: looking at config.sub, not many things supports COFF (or ECOFF). |
| # 20:57:24 |
y_morin |
xvilka: what's the reason for using COFF? |
| # 20:59:05 |
xvilka |
it is non-posix embedded system |
| # 21:00:10 |
xvilka |
what difference between coff and ecoff? |
| # 21:03:06 |
y_morin |
xvilka: https://secure.wikimedia.org/wikipedia/en/wiki/Comparison_of_executable_file_formats |
| # 21:08:02 |
xvilka |
ah, only 64bit support |
| # 21:08:47 |
y_morin |
xvilka: nope, the table is to be read as "also supports 64-bit) |
| # 21:09:23 |
xvilka |
anyway, looks like i need coff only |
