Hello,
I am having problems running a C++ program using ROOT. It compiles and links without complaint. Here is the linking step:
Then, when I run, I get the error:
But, the file: /usr/local/lib/root/libGpad.so definitely exists.
If I remove the -lGpad flag in the linking, it complains of things like “/usr/local/lib/root/libGui.so: undefined reference to 'TCanvas” when it tries to link.
On the very first look I’d say that your runtime environment is not set up correctly.
The compilation command looks more or less reasonable. But I would’ve implemented it relying on the root-config script a bit more.
So, is the /usr/local/lib/root path in your LD_LIBRARY_PATH or DYLD_LIBRARY_PATH (in case you’re on MacOS X, which I doubt from the application name) environment variable? Did you set up your environment by let’s say sourcing the thisroot.[c]sh script? (Wherever it may be in your installation…)
