Centos 7 Compilation

[simontorres]

I have resolved all dependencies for compiling x11iraf on Centos 7 but now it seems I require changes in the code. I haven't installed iraf in a while...

This is the traceback from a couple of lines before the error appears.

This is a problem with the original x11iraf package. In the current version (in the git repository), it is fixed by commit d7086ee2338b47013d8c733daa39d92add8cbdde. There is no new (fixed) release of x11iraf yet. Instead of using the tarball, you should therefore use the git repository which also has a number of other fixes, with git clone ….

Thanks! I will try that now.
