problem:

i tried install yara in virtualenv , succesful while running app error keep on coming , tried sys link missing library error not rectified.

log:

(venv) root@corpus:/var/www/flaskapp/flaskapp# python __init__.py failed import '/var/www/flaskapp/flaskapp/venv/lib/libyara.so' path = /var/www/flaskapp/flaskapp/venv/bin:/var/www/flaskapp/flaskapp/venv/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin;/var/www/flaskapp/flaskapp/venv/lib traceback (most recent call last):   file "__init__.py", line 26, in <module>     yara_scanner_kiran.yara_detect import yaraclass   file "/var/www/flaskapp/flaskapp/ya/ya.py", line 10, in <module>     import yara   file "/var/www/flaskapp/flaskapp/venv/local/lib/python2.7/site-packages/yara/__init__.py", line 7, in <module>     yara.rules import compile   file "/var/www/flaskapp/flaskapp/venv/local/lib/python2.7/site-packages/yara/rules.py", line 17, in <module>     yara.libyara_wrapper import *   file "/var/www/flaskapp/flaskapp/venv/local/lib/python2.7/site-packages/yara/libyara_wrapper.py", line 315, in <module>     libyaradll = cdll.loadlibrary(library)   file "/usr/lib/python2.7/ctypes/__init__.py", line 440, in loadlibrary     return self._dlltype(name)   file "/usr/lib/python2.7/ctypes/__init__.py", line 362, in __init__     self._handle = _dlopen(self._name, mode) oserror: /var/www/flaskapp/flaskapp/venv/lib/libyara.so: cannot open shared object file: no such file or directory

solution tried:

sudo ln -s /usr/local/lib/libyara.so /usr/lib/libyara.so

other solution tried:

download source tarball , prepared compiling it: tar -zxf yara-3.5.0.tar.gz cd yara-3.5.0 ./bootstrap.sh make sure have automake, libtool, make , gcc installed in system. ubuntu , debian users can use:  sudo apt-get automake libtool make gcc if plan modify yara’s source code may need flex , bison generating lexers , parsers:  sudo apt-get flex bison compile , install yara in standard way:  ./configure make sudo make install

any suggestion on how solve problem ?

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
