| 00:38.38 | mjn3 | as far as i'm concerned, 3.3.4, 3.4.0, and 3.4.1 can go. i'd be tempted to keep 3.4.2 around a bit longer, just to have a quick check in case we see 3.4.3 doing something weird. i've done a lot more testing of 3.4.2 than 3.4.3 |

| 00:58.16 | mjn3 | true |
| 01:20.53 | mjn3 | sjhill: it looks like that 300-120 patch breaks the libjava build. i removed it and the build is going fine. assuming the native build finishes, i'm going to punt it |
| 01:38.51 | sjhill | mjn3: sounds good |
| 01:38.59 | sjhill | i'm getting ready to check in my stuff for 4.1.0 |
| 01:39.25 | sjhill | i haven't tested java/objc yet |
| 01:39.48 | mjn3 | ok. i just finished supper and i'm about to start looking for the reason why the libstdc++ config.h is different for cross and native |

| 01:45.51 | sjhill | that doesn't look good |
| 01:50.46 | mjn3 | doesn't look like any error message i've seen recently |
| 01:51.21 | sjhill | that was for e2fsprogs |
| 01:51.29 | sjhill | everything else is building without errors |
| 01:52.00 | mjn3 | ah. i've only been building the toolchain |
| 01:52.28 | sjhill | hmm, that was the only app that failed |
| 01:52.35 | sjhill | it just built the ext2 and cramfs images |
| 01:52.53 | mjn3 | well, that and gawk since there's some code in it that triggers a failure if limits.h doesn't get fixed up correctly |
| 01:53.16 | sjhill | hmmm, didn't notice that one |
| 01:53.21 | sjhill | let me investigate deeper |
| 02:06.49 | sjhill | gawk built |
| 02:06.57 | sjhill | e2fsprogs is the only bad one |
| 02:07.14 | mjn3 | what's the preprocessed output look like? |
| 02:07.24 | sjhill | i'm still trying to decipher it |
| 02:09.35 | sjhill | e2fsprogs, netkit-base (inetd), util-linux (mkfs.minix) |
| 02:09.40 | sjhill | those are the failures |
| 02:09.49 | sjhill | netkit and util have errors with lvalue problems |
| 02:22.33 | mjn3 | cool. soft float + locale built |
| 02:22.45 | sjhill | great |
| 02:22.56 | sjhill | fixed netkit |
| 02:23.14 | sjhill | gcc-4.x specific |
| 02:23.23 | sjhill | #define SWAP(type, a, b) {type c=(type)a; (type)a=(type)b; (type)b=(type)c;} |
| 02:23.31 | sjhill | replaced with: |
| 02:23.34 | sjhill | #define SWAP(type, a, b) {type c=(type)a; a=(type)b; b=(type)c;} |
| 02:31.22 | sjhill | essentially any place where there is: |
| 02:31.47 | sjhill | (type)var1=(type)var2; |
| 02:31.56 | sjhill | gcc-4.1.0 does not like |
| 02:32.01 | sjhill | looks like it became more strict |
| 02:33.35 | mjn3 | casting the lhs of an assignment was deprecated in gcc 3.4 |
| 02:33.45 | sjhill | well there you go :) |
| 02:33.53 | sjhill | so, you will hit that with 4.0 i would expect |
| 02:34.03 | mjn3 | yep |
| 02:34.13 | sjhill | i'll check in patches to netkit and util-linux in a few minutes |
| 02:34.37 | sjhill | netkit is a one line change |
| 02:34.40 | sjhill | util-linux....about 15 |
| 02:40.02 | mjn3 | hmm... something is hosed with this configure test |
| 02:47.45 | sjhill | whoo boy |
| 02:48.04 | sjhill | xdr.h is going to need an overhaul |
| 03:12.03 | mjn3 | as i recall, it is an ugly mess |
| 03:12.33 | mjn3 | perhaps it is already overhauled in glibc |

| 03:37.56 | sjhill | and that |
| 03:41.22 | mjn3 | afraid it isn't equivalent. what if buf is a char *? it only increments by one char and not by one long |
| 03:46.05 | sjhill | *sigh* |
| 03:46.18 | sjhill | i'm having a heck of time working around this lhs deprecated crap |
| 03:50.06 | mjn3 | yeah. that xdr code is exceedingly nasty |
| 03:54.19 | mjn3 | you might try something like ((long *) (buf = (void *)( ((char *)buf)+sizeof(long) )) )[-1] |
| 03:55.50 | mjn3 | nasty, but i think it is compliant |
| 03:56.08 | mjn3 | disclaimer.... untested |
| 04:00.38 | mjn3 | back in about 30 minutes |
| 04:12.25 | SpanKY | mjn3: work out hte binutils stuff ? |
| 04:14.19 | SpanKY | ah i e-mailed binutils about the tests a day or two ago actually |
| 04:14.36 | SpanKY | i didnt notice the configure.in though ... i'll e-mail about that too |
| 04:26.25 | sjhill | ok |
| 04:26.29 | sjhill | i think this correct now |

| 04:28.00 | sjhill | +*((u_int32_t *)buf) = (long)htonl((u_long)v); |
| 04:28.08 | sjhill | +(u_int32_t *)buf++; |
| 04:28.16 | sjhill | i think that takes care of them |
| 04:28.31 | sjhill | mjn3: what's it look like? |
| 04:28.32 | mjn3 | SpanKY: just a few fixes. what's in svn now builds both cross and native for mipsel |
| 04:28.48 | mjn3 | gimme a sec. just walked in the door |
| 04:29.14 | SpanKY | yeah i saw the diffs on the list |
| 04:29.27 | SpanKY | i e-mailed the configure.in change upstream |
| 04:30.25 | mjn3 | sjhill: there's still an issue if buff is not a long *. that's why i went to the trouble of casting to char * and adding sizeof(long). i don't think you can portably increment a cast pointer |
| 04:30.56 | sjhill | but all of the macros do things in term of longs no matter what |
| 04:31.00 | mjn3 | SpanKY: there's still an issue with cross vs native libstdc++ config. i'm looking into it |
| 04:31.38 | sjhill | a long is always returned and then is casted, even it is a demotion in type |
| 04:31.40 | mjn3 | but what does the buf++ do? the macros have no guarantee on the type passed, do they? |
| 04:32.09 | sjhill | no |
| 04:32.18 | sjhill | but it gets cast to a u_int32_t |
| 04:32.22 | sjhill | regardless |
| 04:32.34 | sjhill | is my *((u_int32_t*)buf++)) incorrect? |
| 04:32.52 | sjhill | i want buf cast to a u_int32_t pointer and incremented |
| 04:32.59 | sjhill | i don't have my C book handy |
| 04:34.08 | SpanKY | mjn3: i havent gotten the gall up yet to ask gcc devs to change their config files to remove the '-gnu*' ;) |
| 04:34.58 | mjn3 | sjhill: i remember fixing some things like that in my string code a while back. you could run a test |
| 04:36.26 | mjn3 | SpanKY: heh |
| 04:37.16 | mjn3 | i haven't even tried building for anything other that x86 and mipsel. in particular, i'm not sure about one of the cris-related patches |
| 04:37.22 | sjhill | mjn3: can you point me to that? |
| 04:37.40 | mjn3 | sjhill: to what? |

| 17:00.15 | mjn3 | think it is mips specific. doing an x86 build now |
| 18:29.51 | solar | is there an easy way to alias an applet? like sash for ash |
| 21:01.32 | mjn3 | solar: you'd have to change the applet table in busybox since the main busybox app checks the invocation name and does a bsearch in the applet table to find the appropriate app_main to run |
| 21:05.46 | solar | ahh like CONFIG_TEST in ./include/applets.h |
| 21:06.13 | mjn3 | yes |
| 21:07.28 | mjn3 | just remember that it does a binary search so the applet table must remain sorted |
| 21:10.31 | solar | http://rafb.net/paste/results/XheBBR22.txt |
