Cannot recompile assembled code[BUG]

[ha2san]

When I try to compile the assembled code I get this error

(retro) bash-5.1$ file binary/quich

Steps To Reproduce:

Source code can be found at https://github.com/Usbac/quich, I added -pie to the
CFLAGS to make sure that the binary is compiled as position independent code
(PIE). Adding or removing the -g flags does not change anything.

Environment:

OS: 5.14.21-2-MANJARO x86_64 GNU/Linux
GCC: gcc (GCC) 11.2.0
retrowrite at commit: 117dad5

one of the errors seems for example to come from this line:

.type	stdout@GLIBC_2.2.5_b220,@object

Hi ha2san! I have met the same problem as you on aarch64 and gcc 9.4.0. I solved the problem with delete all the @GLIBC_*** in the .s files. Here's the command: sed -i 's/@GLIBC_2.17//g' $AS_FILE.s.
Hope this helps :)
