So this is reproducible with any gcc version, I think. For instance: $ gcc-15 -Wl,-rpath -Wl,$HOME/lib /usr/bin/ld: /usr/lib/gcc/x86_64-linux-gnu/15/../../../x86_64-linux-gnu/Scrt1.o: in function `_start': (.text+0x17): undefined reference to `main' collect2: error: ld returned 1 exit status The arguments are not input files, so that this error message is unexpected. -- Vincent Lefèvre <[email protected]> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / Pascaline project (LIP, ENS-Lyon)
