--- Comment #6 from Boris Kolpackov <boris at kolpackov dot net> --- I was under the impression that only something runnable would be useful, but if all that's need is a preprocessed translation unit, then that's no problem at all. I've also attached the translation unit with the workaround for your reference. Both files were produced with the following command line using GCC 12.2.0 (Debian 12.2.0-3): g++-12 ... -DLIBBUILD2_SHARED_BUILD -DLIBBUILD2_CC_SHARED_BUILD -DLIBBUILD2_BIN_SHARED -DLIBBUILD2_SHARED -DLIBBUTL_SHARED -DLIBPKG_CONFIG_SHARED -g -std=c++23 -finput-charset=UTF-8 -fPIC -E -fdirectives-only -o compile-rule.ii compile-rule.cxx And should be compiled with: g++-12 -DLIBBUILD2_SHARED_BUILD -DLIBBUILD2_CC_SHARED_BUILD -DLIBBUILD2_BIN_SHARED -DLIBBUILD2_SHARED -DLIBBUTL_SHARED -DLIBPKG_CONFIG_SHARED -g -std=c++23 -finput-charset=UTF-8 -fPIC -o compile-rule.o -c -fdirectives-only compile-rule.ii Let me know if there is anything else you need.
