I promised to try a *clean build* with MacPorts, afterwards, next week, and after this a combination of clean build until MacPorts tries to extract GCC 16 to have the prerequisites activated in MacPorts and then performing the actual build outside of MacPorts, in July. `port deps gcc16` tells me that this software is needed for building: Full Name: gcc16 @16.1.0_0+stdlib_flag Extract Dependencies: xz Build Dependencies: m4, texinfo, gcc10-bootstrap Library Dependencies: cctools, gmp, isl, ld64, libiconv, libmpc, mpfr, zlib, zstd, libgcc xz to help extract the GCC 16 archive is not provided by Apple. The system's GNU M4 is version 1.4.6. The system's GNU texinfo is version 4.8. The system's version of cctools (ar, as, libtool, nm, otool, ranlib, size, strings, strip) are unknown (to me). The system does not seem to have gmp. The system does not seem to have isl. The system's version of ld64 is "85.2.1" (MacPorts provides version "97.17" supporting i386 x86_64 ppc ppc64 armv6 armv7). The system's version of GNU libiconv is 1.11. The system does not seem to have libmpc. The system does not seem to have mpfr. The system's version of libz is 1.2.3. The system does not seem to have a zstd. (libgcc only seems to mean something to MacPorts, outside it's probably meaningless.) GNU Make is missing as dependency (3.81 system, 4.4.1 by MacPorts). gcc10-bootstrap is only listed as a build dependency here, but in reality it does not exist on my Leopard, because it does not build here. Starting again `port -vs build gcc16` will activate all that is necessary. Writing this command will introduce less failures then me trying to install all prerequisites ports manually. But I could also try to build with M4, texinfo, cctools, ld64, libiconv, libz from the 17 years old system. Iain, I also could try both builds, mixed with old Leopard software or using mostly modern MacPorts software. It's just a question of setting environment values like PATH, PKG_CONFIG_PATH.
