I would say its likely an issue with you using -flto. Just to double check the obvious: 1. /usr/lib64/libaio.so is a GNU ld script to /lib64/libaio.so.1 correct? (you'll have to cat the file out) 1a. the OUTPUT_FORMAT is elf64-x86-64? 2. /lib64/libaio.so.1 and what it points to exists? 3. "readelf -s /lib64/libaio.so.1 | grep io_cancel" finds something?
In fact I just noticed you used gold as well. There's a known issue with ld scripts, gold and -flto.
Suggestions, Toolchain Ninjas?
This is being linked using gold, but not "-flto", see "-fno-lto" in CFLAGS and LDFLAGS. 1. /usr/lib64/libaio.so is a GNU ld script to /lib64/libaio.so.1 correct? (you'll have to cat the file out) cat /usr/lib64/libaio.so /* GNU ld script Since Gentoo has critical dynamic libraries in /lib, and the static versions in /usr/lib, we need to have a "fake" dynamic lib in /usr/lib, otherwise we run into linking problems. This "fake" dynamic lib is a linker script that redirects the linker to the real lib. And yes, this works in the cross- compiling scenario as the sysroot-ed linker will prepend the real path.

Try rebuilding your libaio, as its literally missing the symbols you mentioned. I assume you have 0.3.109-r3 installed?
Could be related to #437460 as well.
I rebuilt libaio with "-fno-lto", and that seems to have fixed it. readelf -s /lib64/libaio.so.1.0.1 Symbol table '.dynsym' contains 15 entries: Num: Value Size Type Bind Vis Ndx Name 0: 0000000000000000 0 NOTYPE LOCAL DEFAULT UND 1: 00000000000005c0 53 FUNC GLOBAL DEFAULT 8 io_getevents@@LIBAIO_0.4 2: 0000000000000520 22 FUNC GLOBAL DEFAULT 8 io_queue_init@@LIBAIO_0.1 3: 0000000000000550 14 FUNC GLOBAL DEFAULT 8 io_queue_wait@@LIBAIO_0.4 4: 0000000000000540 5 FUNC GLOBAL DEFAULT 8 io_queue_release@@LIBAIO_0.1 5: 0000000000000620 11 FUNC GLOBAL DEFAULT 8 io_setup@@LIBAIO_0.4 6: 0000000000000630 8 FUNC GLOBAL DEFAULT 8 io_destroy@@LIBAIO_0.4 7: 00000000000006b0 61 FUNC GLOBAL DEFAULT 8 io_getevents@LIBAIO_0.1 8: 0000000000000560 73 FUNC GLOBAL DEFAULT 8 io_queue_run@@LIBAIO_0.1 9: 0000000000000660 67 FUNC GLOBAL DEFAULT 8 io_queue_wait@LIBAIO_0.1 10: 0000000000000600 8 FUNC GLOBAL DEFAULT 8 io_submit@@LIBAIO_0.1 11: 0000000000000610 8 FUNC GLOBAL DEFAULT 8 io_cancel@@LIBAIO_0.4 12: 0000000000000640 17 FUNC GLOBAL DEFAULT 8 io_cancel@LIBAIO_0.1 13: 0000000000000000 0 OBJECT GLOBAL DEFAULT ABS LIBAIO_0.1 14: 0000000000000000 0 OBJECT GLOBAL DEFAULT ABS LIBAIO_0.4 I could have sworn I tried rebuilding libaio with "-fno-lto", but I must have missed updating the portage/package.env.
(In reply to comment #7) > Try rebuilding your libaio, as its literally missing the symbols you > mentioned. I assume you have 0.3.109-r3 installed? yep, dev-libs/libaio-0.3.109-r3 (rebuilt with "-fno-lto" fixed)
Nothing for toolchain to do here then. LTO is unsupported.
Well I guess marking this as fixed then since you have a workaround for the issue. If the toolchain guys won't support LTO, then packages using that toolchain can't possibly support it. Sorry.

If the toolchain guys won't support LTO, then packages using that > toolchain can't possibly support it. Sorry. I don't mind being a canary in the coal mine for the LTO stuff. I am willing to bet a lot of the issues with LTO are common across portage. Unfortunately I don't have the spare time to prove the theory at the moment. Also, whether they're stability issues with LTO or issues in the packages, I'm not sure.
