mysql - OS X Lion with xampp + rails + mysql2 gem -

-

i'm stuck trying figure out how os x lion xampp installation's mysql work mysql2 gem in rails.

here's i've tried:

  • installed xampp dev kit
  • installed mysql5-server both port , brew. both of i've uninstalled. didn't fix problem.
  • installed mysql5 community edition dmg file. uninstalled didn't fix problem.
  • downloaded 32-bit version of mysql5 community edition tar. extracted folder '/var/mysql'

here's command i'm running try , installed:

gem install mysql2 -- --with-mysql-dir=/var/mysql --with-mysql-include= /var/mysql/include --with-mysql-lib=/var/mysql/lib --with-mysql-config= /applications/xampp/xamppfiles/bin/mysql_config

i'm @ loss how work. thing can think of i'm somehow not pointing directories correctly. i've tried removing /include/, /mysql/ , /lib/ with-mysql-include, with-mysql-dir , with-mysql-lib configuration options. no luck that. i've tried pointing xampp installation. no luck still.

the error returned is:

error: error installing mysql2: error: failed build gem native extension.  /users/user/.rvm/rubies/ruby-1.9.3-p194/bin/ruby extconf.rb --with-mysql-dir=/var/mysql --with-mysql-include=/var/mysql/include --with-mysql-lib=/var/mysql --with-mysql-config=/applications/xampp/xamppfiles/bin/mysql_config checking rb_thread_blocking_region()... yes checking rb_wait_for_single_fd()... yes checking mysql.h... no checking mysql/mysql.h... no ----- mysql.h missing.  please check installation of mysql , try again. ----- *** extconf.rb failed *** not create makefile due reason, lack of necessary libraries and/or headers.  check mkmf.log file more details.  may need configuration options.  provided configuration options:     --with-opt-dir     --with-opt-include     --without-opt-include=${opt-dir}/include     --with-opt-lib     --without-opt-lib=${opt-dir}/lib     --with-make-prog     --without-make-prog     --srcdir=.     --curdir     --ruby=/users/user/.rvm/rubies/ruby-1.9.3-p194/bin/ruby     --with-mysql-config   gem files remain installed in /users/user/.rvm/gems/ruby-1.9.3-p194/gems/mysql2-0.3.11 inspection. results logged /users/user/.rvm/gems/ruby-1.9.3-p194/gems/mysql2-0.3.11/ext/mysql2/gem_make.out

it'd better not bother stuff xampp provides, , install fresh copy of mysql, , simplify gem command installing mysql2:

brew install mysql gem install mysql2

you getting errors installing gem after installing mysql through homebrew because of this:

--with-mysql-dir=/var/mysql --with-mysql-include= \ /var/mysql/include --with-mysql-lib=/var/mysql/lib --with-mysql-config= \ /applications/xampp/xamppfiles/bin/mysql_config

so removing solves problem.

c++ - Using OpenSSL in a multi-threaded application -

-
i have been writing soap client application in c++ on ubuntu using openssl https transport , pthreads threading. have number of threads - 1 central data acquisition thread periodically gets worker threads make soap requests via shared mutex protected queues. reading documentation openssl found is openssl thread-safe? in openssl faq describes mechanisms required ensure thread safety when using openssl. implemented , works fine. the reason question conceptual difficulty really. thinking implementing same functionality application has already, instead of using threads, create 2 seperate applications : 1 worker thread (of multiple copies running) , main data acquisition thread. use tcp sockets communicate between 2 rather mutex protected queues. may bad idea not important - confusing me would have implement same functions required ensure openssl thread safety in second approach or not? my guess not have , treated independent (indeed surely must many applications use openssl) re...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
