qmake LIBS

[rrlangly]

Anyone help w/ the following errors. I'm not sure I've got the correct stuff in my makefile's *.pro because of these errors.

$ ./myapp --help
./myapp: error while loading shared libraries: libtinyxml.so.1: cannot open shared object file: No such file or directory

INCLUDEPATH += ../includes ./includes ../libs/tinyxml
LIBS += -L/usr/lib64/boost-1_41 -lboost_program_options -L../libs/tinyxml -ltinyxml
 
CONFIG +=
HEADERS +=
SOURCES += main.cpp xmldoc.cpp
TARGET = myapp

INCLUDEPATH += ../includes ./includes ../libs/tinyxml
LIBS += -L/usr/lib64/boost-1_41 -lboost_program_options -L../libs/tinyxml -ltinyxml

CONFIG +=
HEADERS +=
SOURCES += main.cpp xmldoc.cpp
TARGET = myapp

And if I do "cd ../libs/tinyxml", I have this built.

You shouldn't use relative paths when specifying dynamic library locations. Try substituting absolute paths and see if that helps.

More importantly, your app needs to be able to find the dynamic libraries at runtime. Either set your LD_LIBRARY_PATH environment variable with the absolute path to your libraries, or (as a temporary measure) put your app in the same directory as your libraries and run it from there; you'll need to do something more robust eventually, but at least you'll get past this particular problem.

Finally, read up on rpath and other topics concerning runtime linking.
