Fails to detect build tools correctly on macOS Big Sur

[hrbrmstr]

I've left a similar issue for RStudio's internal checks but {pkgbuild} fails to properly see clearly installed build tools during package checks inside RStudio.

$ xcode-select --print-path
/Applications/Xcode.app/Contents/Developer

In RStudio (latest dailies) I can't even debug this issue:

pkgbuild::check_build_tools(debug = TRUE)
Error: Could not find tools necessary to compile a package
Call `pkgbuild::check_build_tools(debug = TRUE)` to diagnose the problem.

When I do the same in a terminal R console:

> pkgbuild::check_build_tools(debug = TRUE)
Trying to compile a simple C file
Running /Library/Frameworks/R.framework/Resources/bin/R CMD SHLIB foo.c
ccache clang -Qunused-arguments -I"/Library/Frameworks/R.framework/Resources/include" -DNDEBUG   -I/usr/local/include   -fPIC  -Wall -g -O2  -c foo.c -o foo.o
ccache clang -Qunused-arguments -dynamiclib -Wl,-headerpad_max_install_names -undefined dynamic_lookup -single_module -multiply_defined suppress -L/Library/Frameworks/R.framework/Resources/lib -L/usr/local/lib -o foo.so foo.o -F/Library/Frameworks/R.framework/.. -framework R -Wl,-framework -Wl,CoreFoundation

Your system is ready to build packages!

macOS Big Sur (latest Beta), R 4.0.2, Xcode (latest beta)

If pkgbuild works in the console but not in RStudio I think this must be an RStudio issue, there really isn't any RStudio specific code in pkgbuild.

Well, since you're kinda all on the same team, mebbe y'all could fix this holistically? Or, is that unreasonable?

I've got the same issue

Pretty sure the only course of action is to waste disk space and install the command line tools as well as Xcode (or jury rig symbolic links) since there seems to be no impetus to resolve this across RStudio IDE behavior and the supporting packages it relies upon.

Hi, I have this issue following a tutorial

• installed and loaded devtools
• installed and loaded testthat
• ran xcode-select --install which took ~30 min
• R version 4.0.5 (2021-03-31)

all i did was edit the DESCRIPTION file and ran check()

==> devtools::check()

I opened a new issue for this, hopefully it will be fixed this time: https://github.com/rstudio/rstudio/issues/10203

[gaborcsardi]

I think we can work around this in pkgbuild, and first try to find a compiler on our own, and only fall back on RStudio if we fail to find one.

[PythonCoderUnicorn]

update, I installed the full XCode and then everything worked, which sucks as I didn't want to have the full software. Thanks !

[gaborcsardi]

@PythonCoderUnicorn Well, this issue is about the opposite, i.e. that pkgbuild in RStudio does not work with the full Xcode and only works with the command line tools.

[PythonCoderUnicorn]

okay, good to know. Just wanted to share that for me, the full installed fixed my issues of beginner pkg dev, so maybe there is issues unknown to me on this. I thank you for your work on this.
