math - Compiling a .c file using gimptool -

-

i've found gimp plugin on github i'd use: https://github.com/possiblyphilip/koi (check out, seems pretty cool).

but when try install author suggests:

sudo apt-get install libgimp2.0-dev sudo gimptool-2.0 --install-admin koi.c

i following error:

/usr/bin/ld: /tmp/ccaahhwn.o: undefined reference symbol 'cos@@glibc_2.0' //lib/i386-linux-gnu/libm.so.6: error adding symbols: dso missing command line collect2: error: ld returned 1 exit status

how can fix this? i've done googling , found this answer, suggesting error caused missing math library should added in linking stage (-lm). problem gimptool automatically , don't think there's way tell add anything.

the author of plugin says prebuilt binary available, found. i've e-mailed guy, didn't answer yet.

if it's obvious - i'm sorry, can't figure out.

ps nevermind - i've managed install using

sudo cc=gcc cflags=-o3 libs=-lm gimptool-2.0 --install-admin koi.c

asp.net - 'System.Web.HttpContext' does not contain a definition for 'GetOwinContext' Mystery -

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

-
there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
