php and c application data exchange .so lib linkage problem

JacobNovitsky

I use below structure for my distributed c/c/qt app which uses multiple .so libs.
I'm testing some possibilities of php and web interface and facing below problem:

/home/j/OSL/build/lib/libOSL.so

I'm making web interface for my engine and learning how to exchange data.

I use below command to interfere with my C application

<?php

function sendRequestC() {
exec('/opt/lampp/htdocs/app/EXN/build/EXN 1 2 3, $output, $retval);
}
?>

If I dont link any .so libs its works as designed

I usually face LD_EXPORT problem using distrubuted .so libs for my c/cpp apps.

But currently I tested it to be visible with my ld environment:

echo $LD_LIBRARY_PATH=/home/j/OSL/build/lib

Also it is visible through regular c application call

/opt/lampp/htdocs/app/EXN/build/EXN

return value: 1

When I call php script it returns nothing.
Usually if session is fine, I get array returned from C program.

qt pro file:

TEMPLATE = app
CONFIG += c
TARGET = EXN

DESTDIR = /opt/lampp/htdocs/app/EXN/build



HEADERS += \
  
   

SOURCES += \
   
	main.c


INCLUDEPATH += /opt/lampp/htdocs/app/EXN/OSL

# /opt/lampp/htdocs/app/EXN/lib/libOSL.so

 LIBS += -L/opt/lampp/htdocs/app/EXN/lib/ -lOSL -ldl


QMAKE_LFLAGS += -pthread


QMAKE_CFLAGS_DEBUG   += -O0 -g
QMAKE_CFLAGS_RELEASE += -O2 -DNDEBUG

DISTFILES += \
    ../../../opt/lampp/htdocs/app/EXN/libOSL.so

Hi,

What do you mean by web interface ?
