Thanks for your prompt reply (on a weekend!), Ian. But I think we’re missing the point (see red text)…

Well, you’re not likely to find that helpful, as such “lines” are generated by a script or process in a very complex installation process for ATLAS <https://sourceforge.net/projects/math-atlas/>. Here’s a snippet of one of hundreds of such errors (after 3 small successes)… gcc -I/tmp/Atlas/src/..//CONFIG/include -g -w -o xisgcc /tmp/Atlas/src/..//CONFIG/src/IsGcc.c atlconf_misc.o gcc -I/tmp/Atlas/src/..//CONFIG/include -g -w -c /tmp/Atlas/src/..//CONFIG/src/probe_comp.c gcc -I/tmp/Atlas/src/..//CONFIG/include -g -w -o xprobe_comp probe_comp.o atlconf_misc.o rm -f config1.out /Applications/Xcode.app/Contents/Developer/usr/bin/make atlas_run atldir=/tmp/Atlas/build exe=xprobe_comp redir=config1.out \ args="-v 0 -o atlconf.txt -O 12 -A 43 -Si nof77 0 -V 976 -b 64 -d b /tmp/Atlas/build" cd /tmp/Atlas/build ; ./xprobe_comp -v 0 -o atlconf.txt -O 12 -A 43 -Si nof77 0 -V 976 -b 64 -d b /tmp/Atlas/build > config1.out In file included from /tmp/Atlas/src/..//CONFIG/src/backend/comptestC.c:1: /opt/local/lib/gcc14/gcc/x86_64-apple-darwin21/14.2.0/include-fixed/stdio.h:80:14: error: expected ';' before 'extern' 80 | __BEGIN_DECLS | ^ | ; 81 | extern FILE *__stdinp; > >> I find that it is unusable, because… >> >> The files in gcc14/…/14.2.0/include-fixed/ , which have been auto-edited by >> script fixincludes, contain the undefined (& deprecated >> <https://www.gnu.org/software/libtool/manual/html_node/C-header-files.html>) >> symbols: >> __BEGIN_DECLS and __END_DECLS ! > > We do not have any control over what the OS headers use - you can file a > Feedback with Apple to make queries / observations to them > (https://feedbackassistant.apple.com). But you do have such control over the (very few) headers in gcc14/…/14.2.0/include-fixed/ ! (That was the whole point of my message — see above.) One such Gnu-modified <https://www.gnu.org/software/autogen/fixinc.html> header begins thusly… /* DO NOT EDIT THIS FILE. It has been auto-edited by fixincludes from: "/Library/Developer/CommandLineTools/SDKs/MacOSX12.sdk/usr/include/stdio.h" This had to be done to correct non-standard usages in the original, manufacturer supplied header file. */ #ifndef FIXINC_WRAP_STDIO_H_STDIO_STDARG_H #define FIXINC_WRAP_STDIO_H_STDIO_STDARG_H 1 . . So I guess someone may have fed unfortunate choices into fixincludes. ——— I installed gnu compilers instead of using clang because some ATLAS documentation warned that clang was very inefficient for this very compute-intensive system. (Their installer even does detailed cpu timing tests to determine how to configure their codes to optimize performance!) But now I see a possibly more recent comment that modern clang is not so bad. So how can I prevent any install process from finding and using gnu compilers (without deleting them from /opt/local)? I ask also because I have another different problem porting pgplot <https://sites.astro.caltech.edu/~tjp/pgplot/>. Is MacPorts mixing in clang stuff while using your gfortran? … :debug:build build phase started at Sat Aug 31 20:30:32 PDT 2024 :notice:build ---> Building pgplot :debug:build Executing org.macports.build (pgplot) | | :info:build make: Entering directory `/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_graphics_pgplot/pgplot/work/build' :info:build /opt/local/bin/gfortran-mp-14 -c -Os -fno-backslash -fallow-argument-mismatch /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_graphics_pgplot/pgplot/work/pgplot/src/pgarro.f :info:build clang (LLVM option parsing): Unknown command line argument '-x86-pad-for-align=false'.
