| 09:41.21 | cahbtexhuk | hi everybody |
| 09:41.49 | cahbtexhuk | can anybody help me with some cross-compilation problems? |
| 09:42.33 | jackmitchell | post your question and find out |
| 09:43.29 | cahbtexhuk | we're trying to cross-compile our project to run it on arm machine |
| 09:44.22 | cahbtexhuk | it uses a lot of different libs, one of them is cppdb |
| 09:44.51 | cahbtexhuk | and it gives us a headache |
| 09:46.04 | cahbtexhuk | if we compile the project as is, just replacing g++ with arm-blabla-gcc - everything compiles, links, but gives segfault |
| 09:46.40 | cahbtexhuk | one of the solutions found online was to compile with -fPIC -shared |
| 09:47.20 | cahbtexhuk | still, segfault |
| 09:47.42 | cahbtexhuk | ah, sorry, no |
| 09:50.11 | cahbtexhuk | this is how we tried to compile the project with cppdb |
| 09:50.12 | cahbtexhuk | http://pastebin.com/GAw02Hut |
| 09:50.28 | cahbtexhuk | and a little bit more of the same problem here |
| 09:50.28 | cahbtexhuk | http://www.marshut.com/rkiyt/cppdb-compile-lib.html |
| 10:57.47 | jackmitchell | is the cppdb library compiled by the arm compiler too? |
| 10:58.13 | jackmitchell | cahbtexhuk: if not, then therein lies your problem, you can't link an arm binary with an X86 lib |
| 10:58.33 | cahbtexhuk | нуфрб Ш гтвукыефтв ерфе |
| 10:58.39 | cahbtexhuk | oops |
| 10:58.50 | cahbtexhuk | yeah, i'm aware of that |
| 10:59.33 | cahbtexhuk | and it is compiled by arm compiler as well |
| 11:01.32 | jackmitchell | hmm, I'm not sure; I'm definitely no cmake expert, but it sounds like you need to revisit and understand the build system a bit better |
| 11:02.14 | jackmitchell | I would expect something somewhere is getting contaminated by the host maybe |
| 11:02.40 | jackmitchell | especially if you're using a lot of libraries |
| 11:03.26 | jackmitchell | have you managed to sucessfully compile and run a simple hello_world project? |
| 11:03.55 | jackmitchell | then build up from there |
| 11:04.01 | cahbtexhuk | yup |
| 11:04.36 | cahbtexhuk | we can exclude cppdb from the project and it compiles and runs |
| 11:04.43 | jackmitchell | ah, ok |
| 11:04.51 | jackmitchell | so is cppdb cross compile compatible? |
| 11:05.08 | jackmitchell | i.e. are you sure it doesn't include any specific X86 asm for example |
| 11:05.58 | jackmitchell | you don't see it so much any more, but a few years ago you couldn't take it for granted everything would run on arm |

| 19:55.43 | malkav | hello, i'm looking for a SNMP MIB that provides me with the current time a linux process has been active for. Have looked the default net-snmp MIBs and they do not have this information. Anybody knows anything that might help? Thanks in advance. |
