X11/Intrinsic.h: No such file or dictory

[Vital-Fernandez]

I wonder if anyone could advice me on this issue:

I am installing x11iraf (and iraf) on an ubuntu 20.04 virtual machine (this one is on windows 10)

The instructions are very clear and I managed to install the dependencies and iraf without issues. But I am getting this error once I build with build:

make -C obm
make[1]: Entering directory '/home/vital/x11iraf-2.0-2020.06.15/obm'

Thank you for any advice

You should try to install libxt-dev, which gives a file /usr/include/X11/Intrinsic.h. I am however wondering why it is not installed as it is a depedency of libxmu-dev. Can you check this?

Also, you seem to use a non-standard compiler (from anaconda3), with a non-standard system include (-isystem /home/vital/anaconda3/include). In this case, you must ensure yourself that all includes and libraries are found.

Thank you very much. I have removed the anaconda compiler, reinstalled the dependencies and deleted the folders with the revious installation to start again.

Now however, once I ran the ./install for the iraf installation the terminal gets stuck with the following messages:

./install: 305: NEWLINE: not found ./install: 306: BOLD_ON: not found ./install: 307: ECHO: not found ./install: 308: ECHO: not found ./install: 309: ECHO: not found ./install: 310: BOLD_OFF: not found ./install: 311: NEWLINE: not found ./install: 313: ECHO: not found

Any advice on this issue? Sorry for all the trouble.

I would really recommend not to start with IRAF if you are a newcomer. IRAF is really outdated and reached its end of life. Instead, consider using Astropy, and its affiliated packages, which are capable to solve most of the problems that IRAF was made for. Efforts should go into improving Astropy packages instead of trying to step into IRAF.

For the IRAF problem, the cause is probably that you have defined the $iraf environment variable, which points to some other IRAF installation (from astroconda?). This, and all other environment variables for IRAF (like $host) should be removed, as well as additions to your PATH which prefer using tools from this other IRAF installation. But why don't you just install the iraf package that comes with Ubuntu?

Since the x11iraf problem seems to be solved, I am closing this issue.
