Deploying on linux, executable cannot find shared library at runtime?
-
I have developed an application that works on Windows and I am working on getting it working on Linux. I have been able to link the libraries during compilation but I am unable to get them to work at runtime.
I have looked everyone on the internet and I have implemented what I believe is the correct approach but unfortunately it does not seem to work no matter what I try.
when running ldd on the binary It shows that it cannot find the libraries despite changing the location for which it should be looking.
linux-vdso.so.1 => (0x00007fff757f5000)

libstdc++.so.6 => /usr/lib64/libstdc++.so.6 (0x00000038bd200000)I have implemented this in my project file but unfortunately It does not do anything.
path/to/project/bin <- where the binary is.
path/to/project/lib <- where the library files are.linux {
QMAKE_LFLAGS_RPATH =
QMAKE_LFLAGS += '-Wl,-rpath,\'\$$ORIGIN/../lib\''
}Can anyone work out what I have done wrong?

@AaronKelsey Take a look at https://doc.qt.io/Qt-5/linux-deployment.html

Did you tried to use QMAKE_RPATHDIR that doesn't need to explicitly set compiler flags ??
https://doc.qt.io/qt-5/qmake-variable-reference.html#qmake-rpathdirAlso, did you try to run "readelf -d <binary>" to see if the RPATH has been correctly configured into the application binary ??
