Verification

• My brew doctor output says Your system is ready to brew. and am still able to reproduce my issue.
• I ran brew update and am still able to reproduce my issue.
• I have resolved all warnings from brew doctor and that did not fix my problem.
• I searched for recent similar issues at https://github.com/Homebrew/homebrew-core/issues?q=is%3Aissue and found no duplicates.

What were you trying to do (and why)?

I am trying to reopen issues/160515. As I did not see another option, I openened another issue.

For me xfig does not work, neither as bottle nor installed from source in a M1 machine. There were reports in issue/160515 that the formula does not work on intel as well.

Initially, the problem was reported by @adamny here. I believe the issue belongs here. The OP has the following issue:

I executed: "brew install xfig". No error messages. The last three lines of output where:

==> Installing xfig
==> Pouring xfig--3.2.9.arm64_sonoma.bottle.tar.gz
🍺 /opt/homebrew/Cellar/xfig/3.2.9: 3,005 files, 14.2MB
==> Running brew cleanup xfig...

I see xfig in /opt/homebrew/bin
But when I execute it in mac terminal I get:

Warning: locale not supported by Xlib, locale set to C
Warning: X locale modifiers not supported, using default
Warning: Cannot convert string "--times-medium-r-normal--16-------,---medium-r-normal--16-------,--16-*" to type FontSet
Warning: Unable to load any usable fontset
zsh: segmentation fault xfig
I get the same error when I execute it in xterm under XQuartz. How can I fix it?

This is the backtrace from my process

    frame #0: 0x00000001008b5500 libX11.6.dylib`XmbTextEscapement
    frame #1: 0x0000000100687424 libXaw3d.8.dylib`GetDefaultSize + 92

    frame #9: 0x00000001848610e0 dyld`start + 2360

So it fails while calling the X11 library.

What happened (include all command output)?

Just execute xfig and the segfault happens. At the moment the formula is not functioning. The test passes as it does not try to open an xwindow.

What did you expect to happen?

The xfig application is supposed to be opened.

Step-by-step reproduction instructions (by running brew commands)

brew install xfig
xfig

The following is a patch that works on my system (both intel as well as apple silicon):
echo "179c179\n< Fig.international: True\n---\n> Fig.international: False" | patch /usr/local/etc/X11/app-defaults/Fig

It turns off the utf8 feature which is the main change from 3.2.8 to 3.2.9 which leads to the segmentation fault.

The issue is either in the Xft or the freetype library which are the new dependencies.

Copied from what I posted at #160515:

For anyone who wants to build xfig on their own, and who aren't used to doing that sort of thing

I downloaded the source package here: https://sourceforge.net/projects/mcj/

However, on my system, that version, v. 3.2.9, didn't build--I forget what the errors were-- but I saw that I had an older version, 3.2.8a, and that built and installed without problem. Better to use Homebrew if it works, but I just needed some version of xfig. The simpler instructions, i.e. the three commands to run, are listed at the top of the file named "INSTALL". The only trick is figuring out where the file "app-defaults" lives on your system. On mine it was /opt/X11/share/X11/app-defaults . You need to substitute in the location of app-defaults in the first line between the "<" and ">".

        ./configure --with-appdefaultdir=</path/to/your/app-defaults>
        make
        make install

I didn't have to do anything special to link to fontconfig or anything like that. So if you have trouble building the latest version, it might be worth trying one of the older versions, which are available that that mcj sourceforge site.

I know that some people reading this know all of the above, but I thought it wouldn't hurt to post it for anyone who's not used to this kind of process.

Sounds like something that should be discussed upstream.

Someone reported a similar error with AUR package in https://sourceforge.net/p/mcj/tickets/174/
