Problem With X11iraf

[sctegler]

Hi,

I was able to install IRAF on my iMac running Big Sur; however, when I try to install X11iraf I got the following errors. I would greatly appreciate your help.

This usually happens when the header for Tcl do not match the linked library. For example, when you have (I think) Tcl installed with brew, the header are in /usr/local/include/tcl.h which is in the standard search path, but the corresponding library is not in the standard search path. To resolve this, you need either to remove the additional header in /usr/local/include, or to add the search path for the library. Both the system's default and the brew one work fine here.

Hi Ole,

Thank you for getting back to me so soon. I’m sure the problem is on my end. I’m far from an expert in linux / OSX.

I moved tcl.h to old_tcl.h in /usr/local/include/ and no luck. When I go to an xterm in XQuartz and try an xgterm & I still get

bash: /usr/local/bin/xgterm: Bad CPU type in executable

That seems like I’m trying to run a 32bit application rather than a 64bit application, but I know that’s not right as you’re able to run.

I’m not familiar with tcl.h, brew, …. How would I “add the search path for the library?”

I went to /opt/X11/bin and I see xclock, xterm, …. But no xgterm.

I’d greatly appreciate your help.

This means that you still called your old xgterm from /usr/local/bin/, which is is probably a 32-bit application. You should either copy the newly created xgterm file there (recommended), or you must run it with the full path, i.e. …/x11iraf-2.1/xgterm/xgterm.

Ole,

Thank you so much for making this software available and your help. I’ve got IRAF/xgterm/DS9 up and running on my iMac/Big Sur.
