linux - How can you determine installed versions of the glibc (etc.) libraries? -

-

i'm working embedded linux deployment , using cross compiler tool chain doesn't compile i2c library function calls.

how determine precise versions of libraries on system may rebuild tool chain?

i don't intend replace libraries deployed, know work (including i2c), believe need following:

  • binutils version
  • gcc version
  • glibc
  • kernel (for headers)

i think can assume following binutils library version 2.2.5. kernel modded i've source.

root@dev-box />ls /lib/ -al drwxrwxrwx  3 root root     1024 apr 27 09:44 . drwxrwxrwx 14 root root     1024 jan  1  1970 .. -rwxrwxrwx  1 root root   105379 jan  1  1970 ld-2.2.5.so lrwxrwxrwx  1 root root       16 jan  1  1970 ld-linux.so.2 -> /lib/ld-2.2.5.so lrwxrwxrwx  1 root root       16 jan  1  1970 ld.so.1 -> /lib/ld-2.2.5.so -rwxrwxrwx  1 root root  1288601 jan  1  1970 libc.so.6 -rwxrwxrwx  1 root root    25441 jan  1  1970 libcrypt.so.1 -rwxrwxrwx  1 root root    14303 jan  1  1970 libdl.so.2 -rwxrwxrwx  1 root root    36800 jan  1  1970 libgcc_s.so.1 -rwxrwxrwx  1 root root   530401 jan  1  1970 libm.so.6 -rwxrwxrwx  1 root root    86626 jan  1  1970 libnsl.so.1 -rwxrwxrwx  1 root root    17533 jan  1  1970 libnss_dns.so.2 -rwxrwxrwx  1 root root    46324 jan  1  1970 libnss_files.so.2 -rwxrwxrwx  1 root root    98633 jan  1  1970 libpthread.so.0 -rwxrwxrwx  1 root root    69966 jan  1  1970 libresolv.so.2 -rwxrwxrwx  1 root root    12897 jan  1  1970 libutil.so.1

for glibc:

/lib/libc.so.6

sounds maybe strange run file should print out version information in case

for kernel version use uname

for binutils parsing output of ld --versionmight yield expect, same gcc --version. bit tedious not know way.

javascript - Enclosure Memory Copies -

-
function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

php - Replacing tags in braces, even nested tags, with regex -

-
example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
