Your problem is with the other software, so you might get better advice by posting to their mailing list. This list can help you with gsl issues. For example, uninstalling gsl completely or managing versions of libraries is an Ubuntu topic.
But to answer your question about gsl, does this tutorial help? https://coral.ise.lehigh.edu/jild13/2016/07/11/hello/ To follow this tutorial, you have to understand a little what you are doing. For example, "gsl-*.*" does not mean that literal string with the asterisks. It means "gsl-2.6" because 2.6 is the current stable version (which I deduced by browsing the FTP site and then verifying here: https://www.gnu.org/software/gsl/ ). That's assuming you want the latest GSL, which you probably do but "not compatible" could mean that your other software wants a specific version. If you get errors when you download or make gsl, it would be appropriate to ask about them here. The last step is to make your other software use this GSL. I have no idea how to do this; it may be as simple as editing the Makefile of the software you are trying to compile. It might be a lot more complicated. -Alan On 12/30/2019 12:51 AM, 吴奕洲 wrote: > Hi, > I have installed gsl on ubuntu14.04, but when I compile the program, it > prompts me that lgsl is not compatible.
