I’ve recently “upgraded” to catalina, and compilation of my quantreg package
failed with:
In file included from mcmb.c:11:
/usr/local/clang7/include/c++/v1/stdio.h:108:15: fatal error: 'stdio.h' file
not found
#include_next <stdio.h>
So I’ve tried the following:
1. Upgraded R to 4.0.3
2. Upgraded the fortran compiler to 8.2.0 as suggested.
3. Attempted to reinstall command line tools with Xcode-select
—install. This fails with
a popup that says:
Can’t install the software because it is not currently
available from the Software Update server.
4. Tried again to reinstall Command line tools 12.2 beta 3 from
https://developer.apple.com/download/more/
which successfully installed, but my stdio.h error persisted.
5. Following thread:
http://r-sig-mac.29524.n8.nabble.com/R-SIG-Mac-fatal-error-stdio-h-file-not-found-td889.html
I looked at:
yzzy: which clang /usr/bin/clang
yzzy: xcode-select -p
/Applications/Xcode.app/Contents/Developer
yzzy: xcrun --show-sdk-path
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk
but that didn’t speak to me so further googling led me to:
https://stackoverflow.com/questions/54557659/r-cant-update-packages-clang-cant-find-head-files
so lurking in:
/Library/Developer/CommandLineTools/usr/include/c++/v1
is stdio.h, but I’m feeling a bit queasy at this point and
would appreciate some expert advice.
