--- Comment #50 from Peter Dyballa <Peter_Dyballa at web dot de> --- The build finished some hours ago, quite successfully. Towards the end an error occurred raising a report: Process: conftest [2377] Path: conftest Identifier: conftest Version: ??? (???) Code Type: PPC (Native) Parent Process: sh [2376] Interval Since Last Report: 598482 sec Crashes Since Last Report: 11 Per-App Interval Since Last Report: 0 sec Per-App Crashes Since Last Report: 103 Date/Time: 2026-06-27 18:11:48.655 +0200 OS Version: Mac OS X 10.5.8 (9L31a) Report Version: 6 Anonymous UUID: B98EE308-F5B2-4632-9B82-ECEF2D42D0B9 Exception Type: EXC_BREAKPOINT (SIGTRAP) Exception Codes: 0x0000000000000001, 0x000000008fe0105c Crashed Thread: 0 Dyld Error Message: Symbol not found: _fNotToBeFound Referenced from: /opt/local/var/macports/build/gcc16-f5979bbe/work/build/powerpc-apple-darwin9/libitm/./conftest Expected in: dynamic lookup I thought of testing GCC16, but MacPorts wrote: The following dependencies will be installed: gcc16-libcxx libcxx-powerpc +emutls python27-bootstrap So I threw away that thought. The GCC16 sources where outpacked into my home area. Due to using a Terminal and vi some parts of my work were overwritten. After applying four patches I also changed the meaning of do-compare in some mk files: egrep -n '^do-compare =' Makefile.in config/bootstrap-debug.mk config/bootstrap-debug-lean.mk config/bootstrap-debug-lib.mk Makefile.in:703:do-compare = /usr/bin/true config/bootstrap-debug.mk:12:do-compare = /usr/bin/true config/bootstrap-debug-lean.mk:12:do-compare = /usr/bin/true config/bootstrap-debug-lib.mk:12:do-compare = /usr/bin/true pete 234 /\ ls -l Makefile.in config/bootstrap-debug.mk config/bootstrap-debug-lean.mk config/bootstrap-debug-lib.mk -rw-r--r-- 1 pete admin 2469015 27 Jun 20:23 Makefile.in -rw-r--r-- 1 pete admin 500 27 Jun 20:24 config/bootstrap-debug-lean.mk -rw-r--r-- 1 pete admin 462 27 Jun 20:24 config/bootstrap-debug-lib.mk -rw-r--r-- 1 pete admin 473 27 Jun 20:24 config/bootstrap-debug.mk It was necessary to re-activate these ports: gmp @6.3.0_0 isl @0.24_1 libmpc @1.4.1_0 mpfr @4.2.2_0 Configuration was finally with: ./configure --prefix=/opt/local --build=powerpc-apple-darwin9 --datarootdir=/opt/local/share/gcc-16 --disable-multilib --disable-nls --enable-checking=release --enable-host-shared --enable-languages=c,c++,objc,obj-c++,lto,fortran,algol68,m2,jit --infodir=/opt/local/share/info --libdir=/opt/local/lib/gcc16 --mandir=/opt/local/share/man --program-suffix=-mp-16 --with-bugurl=https://github.com/macos-powerpc/powerpc-ports/issues/new --without-build-config --with-darwin-extra-rpath=/opt/local/lib/libgcc --with-gmp=/opt/local--with-gxx-include-dir=/opt/local/include/gcc16/c++/ --with-isl=/opt/local --with-ld=/usr/bin/ld64 --with-local-prefix=/opt/local --with-mpc=/opt/local --with-mpfr=/opt/local --with-system-zlib --with-gxx-libcxx-include-dir=\"/opt/local/libexec/gcc16/libc++/include/c++/v1\" --with-pkgversion=\"MacOS PowerPC gcc16 16.1.0_0+stdlib_flag\" CPP=/usr/bin/cpp" since GCC was found to be /usr/bin/gcc, but when I start to make GCC16 the first configure script is testing /lib/cpp as pre-processor which is not accepted. What is a possible solution?
