c++ - gcc linker: which input libraries are used? -


i'm debugging linker issues ("undefined reference" symbols supposed in library i'm linking with), , i'm not sure whether compiler using right shared library.

the output i'm looking 1 produced ldd, is, list of libraries full paths... can't use ldd compilation fails before producing output.

the closest have far dumping library search path , checking directories 1 one shared lib in question; wondering whether better way of doing this?

i'm debugging linker issues

you much better answers if show actual error , link command line used.

most did this:

gcc -lfoo main.c

where libfoo.so library defines necessary symbol. read this understand why above command line wrong.

but can't use ldd compilation fails before producing output

your earlier statement said link stage fails. compilation , linking not same thing, please don't mix them up.

i wondering whether better way of doing this

to find out libraries linker using, read man ld. on unix system, command provide better way:

gcc ... -wl,-t

p.s. note there no such thing "gcc linker" -- distinct tools.

java - IntelliJ - No such instance method -

using intellij's 12 ultimate, i'm running following code in debugger: java import play.api.libs.json.jsvalue; public class foo { ... public jsvalue tojson() { ... } public class fooexample { ... foo foo = new foo(); system.out.println("...); //<-- breakpoint at breakpoint, right-clicked source code , picked "evaluate expression," typing in: foo.tojson() . but following error showed up: no such instance method: play.api.libs.json.jsvalue$class.com.foo.foo.tojson () am doing wrong? foo#tojson calls scala code, if matters. edit had breakpoint after instantiation of foo. downvoted it, deserved it. edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is).. a breakpoint hit before line executed. in case foo has not yet been declared or instantiated (i.e. foo constructor has not yet been called). you'll need put breakpoint @ next line (or step on current line) if want evaluate foo .

identifier - Is it possible for an html5 document to have two ids? -

i wondering if html5 element can have 2 ids, this: <button id="thing1" id="thing2" name="button1" onclick="change()">click here</button> or this: <button id="thing1, thing2" name="button1" onclick="change()">click here</button> also, if 1 of ids said 1 thing, , other id said thing, 1 used? tl;dr : no. in versions of html, each element can have 1 id. see the spec : the id attribute specifies element's unique identifier (id). [dom] the value must unique amongst ids in element's home subtree , must contain @ least 1 character. the value must not contain space characters. note: there no other restrictions on form id can take; in particular, ids can consist of digits, start digit, start underscore, consist of punctuation , etc. note: element's unique identifier can used variety of purposes, notably way link specific parts of document usin
