zrafalittle question: somebody did build openwrt recently?04:16
zrafaI get an error and I do not have any idea about the problem (internet and google did not help me).04:16
zrafawhen make...04:17

zrafasorry about the long lines04:17
zrafaif somebody had the same problem recently I would be glad to know why :)04:17
pcercueizrafa: try with i486-linux-gnu-g++04:20
zrafapcercuei: how? I just did make V=s04:44
zrafadid you say to install some i486 package?04:44
zrafado you*04:45
zrafapcercuei: can you explain the idea a bit more? Sorry, I am not an expert in openwrt. I just followed the qi and openwrt instructions to build04:47
pcercueineither am I05:09
pcercueibut g++ doesn't need -lstdc++05:09
viricAre you sure gcc doesn't need stdc++?07:17
viricit requires a c++ compiler since 4.707:17
Action: whitequark fails to understand why should a cross-compiler be a separate binary07:22
viricwhitequark: many parameters are determined at preprocessor time07:24
whitequarkviric: not "gcc". "a cross-compiler"07:25
virictcc behaves the same.07:25
viricclang not?07:25
whitequarkwhen I used to maintain a small distro, like half of the time I was dealing with gcc quirks. sysroot, cross-compiling, etc07:25
virickenc too07:25
whitequarkviric: nope.07:25
whitequarkclang can cross-compile to anything linked in to llvm.07:26
whitequark$ llvm-config --targets-built07:27
whitequarkR600 X86 Sparc PowerPC ARM Mips CellSPU XCore MSP430 CppBackend MBlaze NVPTX Hexagon07:27
whitequarkhere you are.07:27
viricmoreover, one thing is producing code, the other is producing runable binaries.07:27
viricthe glue with the OS07:27
whitequarkyea, you'd need a crosscompiled libc07:27
whitequark... which you can compile with the same clang ;)07:27
wpwrak3rd driver done :) (spi_atben, but this time using spi-gpio) now ... the highlander test for spi_atben*15:56
FergyAAny of you have any experience with xbee modules?20:01
larscdammit, had to abort my tour through cluj downtown early because they canceled my flight, and only after a lot of complaining booked me on a flight 200km from here21:32
wpwrakno good nightlife to spend that extra evening ?21:33
larscthere is no extra evening, I'm going to hop on a cab to be there on time21:34
pcercueithey pay you the ride?21:35
larscI don't know we'll see21:35
wpwrakyeah, i meant with the cancelled flight, you'd have returned a day later and thus had had one more evening. or maybe you've already checked out all the places :)21:35
larscI called them and they were like, yeah so we can give book you on a flight on tuesday, and was like WTF?!21:36
larscand I was like WTF?!21:37
wpwrakoh, i see. not a country where people are in a great hurry :)21:37
larscgood old german lufthansa21:38
larscand it is actually my colleagues, who is here with me, birthday on sunday21:39
wpwrakprobably sub-sub-sub-contracted21:39
larscand he has a big party planned21:39
wpwrakah, i see. that's messy then21:40
wpwrakin general, i tend to keep a buffer of at least 24 hours when traveling. in the good old days, there were rarely problems, and if there were, they tried hard to minimize the delay. but in recent years, you can get bad surprises resulting in the loss of a full day with almost every airline21:42
wpwrakinteresting: atusb is actually pretty well positioned, price-wise. the competition hovers around about twice the price. (packs more software into their dongles, though, but that may not be necessary)21:44
larscwpwrak: I think you've even met my colleague, he told me you guys had a beer a few years ago in ottawa21:45
wpwraki had beers with a lot of people :) especially in ottawa ;-)21:46
larsche was doing blackfin back then21:46
wpwrakat least there's a small chance that i still remember someone with whom i had beers. with the pangalactic gargleblasters (they serve them at a bar/club there) and all the other stuff, such an outcome is less likely :)21:47
wpwrakhmm, blackfin doesn't ring a bell. maybe we just talked about beer.21:48
larsccould be21:48
whitequarkwpwrak: analog devices22:02
whitequarka 16/32 bit family which has nommu linux. all that I know...22:02
wpwraki meant "meeting someone who talked about blackfin" :)22:05
