Hi! I'm Daniel Trujillo,
Hello, Daniel!
I don't know if these kind of packages are of interest, but this is
PrusaSlicer [0], a software to prepare 3D printings (hence I put it
in engineering.scm).
I have submitted “prusa-slicer” together with “libigl” on July 23 but
did’t get any
response: https://debbugs.gnu.org/cgi/bugreport.cgi?bug=49713
We should probably check prior submissions to not duplicate our effort.
The packaged version, 2.3.3 is the latest stable available at this
moment. But this version has as important problem [1]: It cannot be
invoked just naming the executable (through $PATH), because then, it
can't locate the resources directory. I learned **the hard way** that
the fix was applied *after* the release of the 2.3.3 version, so I
decided to backport the fix adding a patch because it's a
show-stopper to have to type the path to the executable in
/gnu/store/... That's the reason why the patch attached to this email
contains, not only the additions to engineering.scm, but also a patch
that implements the solution in the version 2.3.3 codebase (It's
quite simple, it uses a boost function to determine the path to the
executable rather than relying on argv[0]).
This issue is fixed by adding “-DSLIC3R_FHS=1” to #:configure-flags.
No need to patch the source code.
* In order for the above $PATH issue fix to work, it's crucial that
the cmake variable SLIC3R_FHS is set to off. This is the default
value according to the CMakeLists.txt, but because it's so important,
probably it should have been included in the configure-flags
argument? Just for clarity.
Set it to ON and you don’t have to patch the code.
I hope everything is in order, I'm looking forward to see your
comments, and hope I can start contributing more packages to Guix!!
Prusa slicer bundles a lot of third-party libraries. Most of them contain
prusa-specific modifications, but some don’t. “libigl”, “eigen” and
“hidapi” can be
unbundled, so that we can use versions of these libraries provided by
Guix.

You need to patch “cereal” library definition in order for Prusa
slicer to find
this library. I have included this in my patch as well.
