causalTree not compatible with R 4.5.0

[samblechman]

If anyone has updated to R 4.5.0 and tried to reinstall causalTree devtools::install_github("susanathey/causalTree"), they will see a set of errors related to the C compiler (Apple clang version 15.0.0 on my end).

Any possible fixes to this?

Was told "Strict R headers are now the default. This removes the legacy definitions of PI, Calloc, Realloc and Free: use M_PI, R_Calloc, R_Realloc or R_Free instead."

See: https://cran.r-project.org/doc/manuals/r-devel/NEWS.html

To make the necessary changes is rather easy. Just clone this repository to your local machine, cd into the src repository and:
perl -pi -e 's/Calloc\(/R_Calloc\(/g' *, then
perl -pi -e 's/Free\(/R_Free\(/g' *

Then rebuild the package from the package root directory: R CMD build .

Then reinstall the .tar.gz package file: R CMD INSTALL causalTree_0.0.tar.gz (rename version if you want)

At this point, you can open R and use the updated package: library(causalTree)

This doesn't seem to work on Arch Linux. I have R 4.5.1 and gcc 15.2.1. During build I get CTA_rundown.c:102:21: error: too many arguments to function ‘ct_xeval’; expected 0, have 5.
