So, there is not really enough information to go on in this email. I don't know what system you are one, although I'd guess it is some kind of linux. I don't really know what is meant by "so I installed pgplot separately". Installed from source? From the package manager? I don't know why ifeffit's PGPLOT_install script failed for you. It has always worked just fine for me. Anyway, when I did not find a file called "libgcc_path.sh" on my own computer, I turned to good ol' Google. As near as I can tell, cpg/libgcc_path.sh is a script that compiles a simple C program, then probes the result to figure out what libraries it is compiled against. In short, it seems to be a way to figure out how to put the right collection of default -L command line directives into the compilation command so that program compiled against the pgplot library isn't missing anything. Or some such. I don't know how to resolve this problem either and it seems beyond the scope of what I can reasonably support given that went off-script to get pgplot installed on your computer. Doing that sort of thing presumes a certain level of independent spirit.... In the absence of other information, I would recommend that you figure out where libgcc_path.sh got installed on your machine then figure out how to make sure that it gets resolved at Build time. One fragile way to do that would be to "sudo mkdir /cpg" if it doesn't exist. Then make a symlink in /cpg to wherever your copy of libgcc_path.sh resides. Make sure it is accessible and executable by a normal user. B On 08/19/2016 01:26 PM, Gaurab Rimal wrote:

Hello, I have been trying to install demeter in my archlinux machine but have issues in the build process. I had issues installing pgplot from ifeffit git source so I installed pgplot separately (as outlined in the original pgplot instructions). After installing ifeffit and after all dependencies were met, I ran ./Build and got an error about 'cpg/libgcc_path.sh'. Below is the full output from ./Build. I am unsure of this error because it seems to be related to ifeffit and pgplot and do not know how to resolve this.
