Evening! While working on
https://inbox.sourceware.org/20240414001113.1698685-1-ar...@aarsen.me/ I had noticed that libstdc++ currently does not get linked against an in-tree libiconv, as the in-tree libiconv is only a host library. Should it also be a target one? With a quick hack of copying libiconv in the build dir as arm64-apple-darwin21.6.0/libiconv, I had managed to get libstdc++ not to link system libiconv. This implies that simply enabling building iconv as a target library also would suffice. There are considerations with this, though: naturally, this implies that libstdc++ now contains a copy of libiconv as it gets linked in as a '.a'. It appears not to cause a copy of the symbols to be emitted on this platform: cfarm104:gcc-build arsen$ objdump --syms ./aarch64-apple-darwin21.6.0/libstdc++-v3/src/.libs/libstdc++.6.dylib | grep iconv cfarm104:gcc-build arsen$ ... however, even in that case, the symbols are renamed AFAICT: cfarm104:gcc-build arsen$ objdump --syms ./aarch64-apple-darwin21.6.0/libiconv/lib/.libs/libiconv.a | grep iconv ./aarch64-apple-darwin21.6.0/libiconv/lib/.libs/libiconv.a(iconv.o): file format mach-o arm64 00000000000dbbe0 g O __DATA,__data __libiconv_version 0000000000013730 g F __TEXT,__text _iconv_canonicalize 0000000000013080 g F __TEXT,__text _libiconv 00000000000130c0 g F __TEXT,__text _libiconv_close 0000000000012ca0 g F __TEXT,__text _libiconv_open 00000000000130e0 g F __TEXT,__text _libiconv_open_into 0000000000013468 g F __TEXT,__text _libiconvctl 00000000000135ac g F __TEXT,__text _libiconvlist ./aarch64-apple-darwin21.6.0/libiconv/lib/.libs/libiconv.a(localcharset.o): file format mach-o arm64 ./aarch64-apple-darwin21.6.0/libiconv/lib/.libs/libiconv.a(relocatable.o): file format mach-o arm64 00000000000000e4 g F __TEXT,__text _libiconv_relocate 00000000000001e0 g F __TEXT,__text _libiconv_relocate2 0000000000000000 g F __TEXT,__text _libiconv_set_relocation_prefix ... so, that might be okay? What do you think? Should be build a libiconv as a target lib for libstdc++ use? TIA, have a lovely night! -- Arsen Arsenović
