search-path

问题 I want dlopen() every shared library in a specific directory. In order to do that, what is the cleanest way to retrieve linux's library search path. Or Is there a quicker way of find a specific directory in that path ? posix would be better. 回答1: POSIX does not support a mechanism to find out the directories on the shared library search path (it does not mandate LD_LIBRARY_PATH , for example), so any solution is inherently somewhat platform specific. Linux presents some problems because the

问题 I want to change the location of my test code ( tsnnls_test_DKU.c ) and I am unable to make change in makefile to reflect this folder change properly. Some help would be appreciated. I have two questions: 1) How to link object files from different subdirectory 2) include different search paths (3 search paths in my example). In my orinal setup, where makefile works fine, I put my test code tsnnls_test_DKU.c at following location (inside the third party libraries): Dir1 = /home/dkumar

问题 Postgres 9.2.1 on OSX 10.9.2. If I run the following crosstab example query: CREATE EXTENSION tablefunc; CREATE TABLE ct(id SERIAL, rowid TEXT, attribute TEXT, value TEXT); INSERT INTO ct(rowid, attribute, value) VALUES('test1','att1','val1'); SELECT * FROM crosstab( 'select rowid, attribute, value from ct where attribute = ''att2'' or attribute = ''att3'' order by 1,2') AS ct(row_name text, category_1 text, category_2 text, category_3 text); I get: ERROR: extension "tablefunc" already exists

问题 I have a PostgreSQL database table with 4 columns - labeled column_a, column_b, etc. I want to query this table with a simple select query: select * from table_name; I get a handful of results looking like: column_a | column_b ---------+--------- 'a value'|'b_value' But when I use this query: select * from schema_name.table_name; I get the full result: column_a | column_b | column_c | column_d ---------+----------+----------+--------- 'a value'|'b value' |'c value' |'d_value' Columns c and d

问题 I have a table with a character varying(12) field in it which is its PRIMARY KEY. I ran this query SELECT * FROM bg WHERE bg_id ='470370111002' It selects a row from the table. All looks good. Then I try. INSERT INTO csapp_center_bgs(bg_id,center_id) VALUES('470370111002',2) There is a foreign key on bg_id that looks like... ALTER TABLE csapp_center_bgs ADD CONSTRAINT csapp_center_bgs_bg_id_65c818f360c84dc5_fk_bg_bg_id FOREIGN KEY (bg_id) REFERENCES tiger.bg (bg_id) MATCH SIMPLE ON UPDATE NO

问题 My Yii2 is setup with PostgreSQL. Instead of using separate database per project, I like to use schema for each project. Problem with later setup is that I can't figure out how to select default schema "defaultSchema" through configuration. I am having a problem with migrations table because it defaults to "public" schema when I run migration command. Default "public" schema also prevents using database user's search_path. Although I set up my db user with "search_path=myschema, public" I

问题 I updated my Xcode to 5.0. I added some library/framework search paths and the path it's displaying is the absolute path. For example, if my folder is in my desktop it would display /Users/username/Desktop/"foldername"/"subfolder"/"subfolder"/"framework". Because of this, whenever I check out a working copy in another mac, I have to remove references to certain libraries/frameworks and add them back in. Isn't there a way to fix it where I don't have to remove-add reference again? 回答1: Here's

问题 I am trying to maintain an ARM command line (makefile) project using the MSVS 2013 Express IDE, to take advantage of the IDE's advanced code analysis capabilities. The project consists of dozens of directories, each including a "src" and an "include" directories. In order for Intellisense to "understand" the various tokens, I need to add all those "include" directories to the Additional Include Directories search path. Is there a way to recursively add all folders of a project's filesystem to
