I'm not sure how to establish this. In rsb/rtems/build/sparc-rtems6-gdb-0295dde-x86_64-apple-darwin19.6.0-1/build/gdb/config.log I find the following (esa-qual is my local name for the ESA version of rtems-central): $ /Users/butrfeld/REPOS/esa-qual/modules/rsb/rtems/build/sparc-rtems6-gdb-0295dde-x86_64-apple-darwin19.6.0-1/sourceware-mirror-binutils-gdb-0295dde/gdb/configure --srcdir=../../sourceware-mirror-binutils-gdb-0295dde/gdb --cache-file=./config.cache --verbose --disable-nls --disable-gas --disable-binutils --disable-ld --disable-gold --disable-gprof --without-included-gettext --disable-win32-registry --disable-werror --disable-sim --without-zlib --with-expat --with-guile=no --with-python=/Library/Frameworks/Python.framework/Versions/2.7/bin/python2 --prefix=/Users/butrfeld/REPOS/esa-qual/modules/rtems/6 --bindir=/Users/butrfeld/REPOS/esa-qual/modules/rtems/6/bin --exec-prefix=/Users/butrfeld/REPOS/esa-qual/modules/rtems/6 --includedir=/Users/butrfeld/REPOS/esa-qual/modules/rtems/6/include --libdir=/Users/butrfeld/REPOS/esa-qual/modules/rtems/6/lib --mandir=/Users/butrfeld/REPOS/esa-qual/modules/rtems/6/share/man --infodir=/Users/butrfeld/REPOS/esa-qual/modules/rtems/6/share/info --program-transform-name=s&^&sparc-rtems6-& --disable-option-checking --build=x86_64-apple-darwin19.6.0 --host=x86_64-apple-darwin19.6.0 --target=sparc-rtems6 Does this help? > >> What are the criteria for python to be "useable"? > > Does the following help? > > https://git.rtems.org/rtems-source-builder/tree/source-builder/config/gdb-common-1.cfg#n7 > > On MacOS (darwin) I gave up on the library checks and assume if the header is > present the Python install is OK. > > After the build fails there should be a config.log file under `build` ... > > find build -name config.log This finds a lot of files. In folder rsb/rtems/build/sparc-rtems6-gdb-0295dde-x86_64-apple-darwin19.6.0-1/build I find a number of folders, many of which contain a config.log I opened gdb/config.log and searched for "checking whether to use python" and found the transcript below at (A) (to save reading it all, the issues seems to be: clang: error: no such file or directory: 'Python.framework/Versions/2.7/Python' This is now confusing because, in /Library/Frameworks/Python.framework/Versions/2.7 I observe: $ pwd /Library/Frameworks/Python.framework/Versions/2.7 $ file * ...
