linking .so file

JacobNovitsky

When I'm trying to link my so objects from Qt inner terminal or External gnome terminal from my CPP app it does not work, has no effect

if I set if from gnome-terminal it works nicely

I made simple build function but it only works if I loop it and copy then paste manually to gnome-terminal

if there any way to fix it?

j@j:~/QUI-Debug$ cd /home/j/QUI-Debug && export LD_LIBRARY_PATH=/home/j/QPL-Debug/debug/debug:/home/j/SPL-Debug/debug/debug:/home/j/SML-Debug/debug/debug:$LD_LIBRARY_PATH
j@j:~/QUI-Debug$ ldd QUI
linux-vdso.so.1 (0x00007ffedabd8000)
libSpl.so.1 => /home/j/SPL-Debug/debug/debug/libSpl.so.1 (0x00007fe78f188000)
libSml.so.1 => /home/j/SML-Debug/debug/debug/libSml.so.1 (0x00007fe78efd7000)

chunk below did not help either

const char* paths[] = {
"/home/j/SPL-Debug/debug/debug",
"/home/j/SML-Debug/debug/debug"
};

std::string ld_library_path;
for (const char* path : paths) {
    if (!ld_library_path.empty()) ld_library_path += ":";
    ld_library_path += path;
}

cout << "ld_library_path:" << ld_library_path <<endl;

setenv("LD_LIBRARY_PATH", ld_library_path.c_str(), 1);

@JacobNovitsky below seem to solve this task

#!/bin/bash

Set the directories containing the shared object files

SPL_DIR="/home/j/SPL-Debug/debug/debug"
SML_DIR="/home/j/SML-Debug/debug/debug"
QPL_DIR="/home/j/QPL-Debug/debug/debug"

Concatenate the directories with the current LD_LIBRARY_PATH

export LD_LIBRARY_PATH="$SPL_DIR:$SML_DIR:$QPL_DIR:$LD_LIBRARY_PATH"

Print the current LD_LIBRARY_PATH for verification

echo "LD_LIBRARY_PATH is set to: $LD_LIBRARY_PATH"

Use ldd to show the shared libraries used by the QUI application

ldd /home/j/QUI-Debug/QUI
