Hi Martin, Since commit 511122b83c12 ("Filters now support partially specified classes and also prog-if's") binutils older than 2.35 can't build pciutils 3.8.0 when SHARED=yes. cc -O2 -Wall -W -Wno-parentheses -Wstrict-prototypes -Wmissing-prototypes -fPIC -fvisibility=hidden -c -o filter.o filter.c /tmp/ccLtucRG.s: Assembler messages: /tmp/ccLtucRG.s:6: Error: multiple versions [`pci_filter_init@@LIBPCI_3.8'|`pci_filter_init@LIBPCI_3.3'] for symbol `pci_filter_init_v38' /tmp/ccLtucRG.s:8: Error: multiple versions [`pci_filter_parse_slot@@LIBPCI_3.8'|`pci_filter_parse_slot@LIBPCI_3.3'] for symbol `pci_filter_parse_slot_v38' /tmp/ccLtucRG.s:10: Error: multiple versions [`pci_filter_parse_id@@LIBPCI_3.8'|`pci_filter_parse_id@LIBPCI_3.3'] for symbol `pci_filter_parse_id_v38' /tmp/ccLtucRG.s:12: Error: multiple versions [`pci_filter_match@@LIBPCI_3.8'|`pci_filter_match@LIBPCI_3.3'] for symbol `pci_filter_match_v38' The bug appears to be gas/23840[1]. binutils 2.35 was released on July 2020, so many production systems still use broken toolchains. Any suggestion?
