PHP exec and Batik rasterizer -

-

i'm using batik convert svg images pdf. when converting them through terminal everying fine , file gets converted. however, want convert dynamically php exec().

this see when convert terminal:

about convert 1 svg file(s)  converting output.svg /opt/lampp/htdocs/tool/generated/output.pdf...  ... success

when using exec() output limited 'converting output.svg... etc' without ...success part. if server won't wait script finish. also, resulting pdf-file generated empty.

this call in php:

$command = 'cd ~/downloads/batik-1.7 && java -jar batik-rasterizer.jar /opt/lampp/htdocs/tool/generated/output.svg -m "application/pdf"';

$string = exec($command);

echo '{"success": true, "message": "design saved generated/output.svg' . $string . '"}';`

this see in js console:

design saved generated/output.svgconverting output.svg /opt/lampp/htdocs/tool/generated/output.pdf ...

edit:

using stderr got:

no protocol specified exception in thread "main" java.lang.internalerror: can't connect x11 window server using ':0.0' value of display variable.

edit 2:

after googling found solution:

-djava.awt.headless=true :)

thanks guiding me in finding answer!

learn standard streams stdout , stderr.

php - What is the difference between $_SERVER['PATH_INFO'] and $_SERVER['ORIG_PATH_INFO']? -

what’s difference between $_server['path_info'] , $_server['orig_path_info'] ? how use them? when run print_r($_server) , path_info , orig_path_info not present in array. why not? how can enable them? i have read php manual on them, still don’t understand them. the path_info variable present if invoke php script this: http://www.example.com/phpinfo.php/hello_there it's /hello_there part after .php script. if don't invoke url that, there won't $_server["path_info"] environment variable. the porig_ prefix uncommon. path_info standard cgi-environment variable, , should never prefixed. did read that? (there issues around php3/php4 if invoked php interpreter via cgi-bin/ - hardly has such setups today.) for reference: http://www.ietf.org/rfc/rfc3875

i'm attempting recode old c++ program in fortran make use of lapack (i'm aware c++ have lapack++, i'm having lot of trouble installing it, gave up). i didn't have problems compilation, when had variables declared real . when started coding section of program required lapack, found parameters passed dsyev need double precision . tried change double precision (including changing hard coded numbers double precision counterparts, i.e. 0.0 -> 0.0d0) when try compile, following error of functions , subroutines i've written: error: return type mismatch of function <function> @ (1) (real(4)/real(8)) i'm not sure coming from, in program has been changed double precision. for example, i've declared following: double precision :: alpha(3),d(3),zeta1,zeta2 double precision :: a1(3),a2(3),d1(3),d2(3) double precision :: pi pi = 3.14159265359d0 alpha = (/0.109818d0, 0.405771d0, 2.22766d0/) d = (/0.444635d0, 0.535328d0, 0.154329d0 /) 10 i=1,3 ...

queue - mq_receive: message too long -

-
i implementing communication between 2 processes using queue. problem when call function mq_receive, error: message long. i have done following: struct mq_attr attr; long size = attr.mq_msgsize; .... // initializing queue "/gateway" int rc = mq_receive(gateway, buffer, size, &prio); if print size value, size=1, while when print same size program (got same mechanism), not long integer ( -1217186280 )... how can solve error?....so while size = 1, believe it's right "message long" why 1? p.s. have tried put : int rc = mq_receive(gateway, buffer, sizeof(buffer), &prio); but no result. it seems need read docs more carefully. when call mq_receive should pass size of destination buffer. this size must greater mq_msgsize attribute of queue . in addition, seems have error in queue attributes initialisation makes proper mq_receive call impossible. here standard message queue session: fill mq_attr struct ( doc ): struct mq_a...
