c - Makefile.am commands to override library functions -

-

i have open source project relies on open source project (let's call other project x). both written in c. i've had hack pieces of x multi-threading work. causes issues when trying package code distribution. make things easier, i've included entirety of x within mine along few little hacks i've made.

i'd more sophisticated in order keep improved functionality of x (it has frequent releases , mine not) without having repackage whole project (with hacks) within project again each time x has release.

there 3 or 4 functions in need override. can follow going on in ibm tutorial, how can modify makefile.am generate makefile changes suggested in article? summarize, article suggests writing own functions same signatures ones want override (in file called libfuncs.c) , add following 'libs' target makefile:

all: libs setresgid-tester  libs: libfuncs.c              gcc -shared -wl,-soname,libfuncs.so.1 -o libfuncs.so.1.0  libfuncs.c               ln -s libfuncs.so.1.0 libfuncs.so.1              ln -s libfuncs.so.1 libfuncs.so  setresgid-tester: setresgid-tester.c          gcc -o setresgid-tester setresgid-tester.c

all of makes sense me. need do, however, have 'libs' target created me autotools. have makefile.am works right now. how modify produce desired results above? difficult find in autotools documentation, may not have known for.

i'm happy provide more details if helpful. in advance.

plot - Remove Objects from Legend When You Have Also Used Fit, Matlab -

Image
i've plotted data points , fitted exponential curve between them using 'fit' in matlab. problem fit-function got fitted line wanted plot, markers on top of regular markers. solved problem plotting wanted markers on top of unwanted couldn't seen. problem. when want show legends dots in there. how can remove markers legend without removing fitted line since both of them hidden inside fit-function? can stop 'fit' plotting unwanted markers? so, want remove blue dot called 'hoff' in picture below. you can leave out legend-entries manually leaving out handles of lines, dont want in legend. try this: %if plot something, want showing in legend, save handle: h_line = plot(x,y) %you dont want show line? dont anything, plot it: plot(mymarker) %then set legend-> can add text legend-entries %a cell-array containing strings want show up: legend([h_line another_line],{'text1' 'text2'}) with example (see comments) came solution:

java - Why does my date parsing return a weird date? -

-
here code using: string string = "08/07/2013".replace('/', '-'); date date = new simpledateformat("yyyy-mm-dd").parse(string); why date return: "wen jan 3 00:00:00 est 14"? not @ date format told use. edit: need format because database using requires format. the format use parse date string, not match it. using yyyy 08 . use following format: new simpledateformat("dd-mm-yyyy") and why @ replacing / - ? can build pattern original string only: string string = "08/07/2013" date date = new simpledateformat("dd/mm/yyyy").parse(string); and if want date string in yyyy-mm-dd format, can format date using dateformat#format(date) method: string formatteddate = new simpledateformat("yyyy-mm-dd").format(date); see also: change date format in java string simpledateformat java doc
