After bug #631368 was fixed (from which I was affected, too), when =sys-kernel/genkernel-3.5.2.5 now compiles dmraid for the initramfs it fails with this error: [...] gcc -o dmraid dmraid.o commands.o toollib.o -Wl,--no-as-needed -static -L../lib -ldmraid -ldevmapper -lm -lrt -lpthread /usr/lib/gcc/x86_64-pc-linux-gnu/6.4.0/../../../../x86_64-pc-linux-gnu/bin/ld: cannot find -ldevmapper collect2: error: ld returned 1 exit status make[1]: *** [Makefile:71: dmraid] Error 1 make[1]: Leaving directory '/var/tmp/genkernel/10530.2766.32186.16712/dmraid/1.0.0.rc16-3/dmraid/tools' make: *** [make.tmpl:120: tools] Error 2 Full genkernel.log is attached.

Created attachment 512628 [details] genkernel.log with failed dmraid build (Re-attached, initial attachment was rejected due to size limit.)
Do you have lvm2 installed? You should have /lib64/libdevmapper.so* on your system.
(In reply to Robin Johnson from comment #2) > Do you have lvm2 installed? You should have /lib64/libdevmapper.so* on your > system. Yes, lvm2 is installed: [ebuild R ] sys-fs/lvm2-2.02.166-r2::gentoo USE="readline systemd thin udev -clvm -cman -corosync -device-mapper-only -lvm1 -lvm2create_initrd -openais -sanlock (-selinux) (-static) (-static-libs)" 0 KiB And lib is also there: -r-xr-xr-x 1 root root 409K 2. Sep 23:30 /lib64/libdevmapper.so.1.02 Maybe type of the lib is somehow off so that the linker ignores it? $ file /lib64/libdevmapper.so.1.02 /lib64/libdevmapper.so.1.02: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, stripped
I am seeing the same error on my amd64 system since about two weeks ago - if there is any additional information I can provide to resolve the issue, please let me know.
I am experiencing the same problem here with sys-kernel/genkernel-3.5.3.3 . Copying information from https://forums.gentoo.org/viewtopic-p-8240238.html : I invoke genkernel this way: genkernel --dmraid --mdadm --mdadm-config=/etc/mdadm.conf --menuconfig --save-config --install --mountboot --bootloader=grub2 all kernel-genkernel-x86_64-4.14.52-gentoo and System.map-genkernel-x86_64-4.14.52-gentoo are created successfully, and the bug occurs when genkernel compiles in dmraid support: [...] * DMRAID: Adding support (compiling binaries)... * lvm: >> Patching ... * lvm: >> Applying patches... patching file configure.in Hunk #1 succeeded at 32 (offset 1 line).

If the system lvm2 is used here, and gk is trying to build a static dmraid, doesn't the system lvm2 need USE=static-libs on? That seems to help the build o further, then I hit another failure due to bug 644094.

Is there any progress on this issue - can I do anything from my end to get this resolved? FWIW, I tried adding USE=static-libs on lvm2, which for some reason caused a request for eudev, which I don't use at the moment. Frankly, I don't understand what has changed in a way that broke the process that - at least from my POV - used to wok just fine...
Seeing that this issue has been assigned to genkernel maintainers in January and it's September now without any visible progress... Is genkernel essentially unmaintained now?
Dmraid support appears to be, please attach a patch with a fix
(In reply to Ben Kohler from comment #10) > Dmraid support appears to be, please attach a patch with a fix If that's the case then genkernel should say so, and at least warn the user that using --dmraid is liable to compilation/linking issues.
This one is complicated. It's easy to fix the reported issue, i.e. to help dmraid to find "-ldevmapper". But this will only uncover the real problem: It won't find "-ldevmapper-event". That's because since https://gitweb.gentoo.org/proj/genkernel.git/commit/?id=b5719a7a45673faada9502bba39c5e9af9e16a30 we are building lvm2 without dmeventd but this is required to get libdevmapper-event. Like the comment says, it was disabled because of the build failure > libdm-string.c:(.text+0x1481): undefined reference to `nearbyintl' There shouldn't be a build failure -- "-lm" is set. From my understanding linking is failing because "-lm" will be set at the wrong position (too early). Long story short: We have to upgrade lvm2. Current LVM2.2.02.183 we have in repository is a good candidate. However, this will also require libaio. I have a working PoC. Now I need to get this into genkernel.
Dear Thomas, Thank you for the sensible and informative comment. While waiting for the fix, may i ask whether someone could help with the following slightly off-topic question: Is it necessary to add --dmraid to the genkernel argument list if the --mdadm and --mdadm-config arguments are already present? My understanding is that DMRAID does automatic RAID device discovery, so if the file pointed to by --mdadm-config already includes the device information, --dmraid should not be necessary. This could be a workaround while this bug is being worked on, or even a satisfactory solution, at least for simple RAID setups where the configuration is known at boot time.
Most people don't need "--dmraid" these days: You only need dmraid when you are using 'fake' raid provided by some cheap onboard RAID controller aka SoHo, ATARAID, firmware/driver RAID or HostRAID named. Incomplete list of known 'RAID providers' requiring dmraid: Highpoint HPT37X/HPT45X Intel Software RAID LSI Logic MegaRAID NVidia NForce RAID (nvraid) Promise FastTrack Silicon Image(tm) Medley(tm) VIA Software RAID When you use mdraid you only need "--mdadm" option in genkernel for your RAID (aside kernel support). And of course, when you are using real hardware RAID, you don't need any RAID support in genkernel at all, you only need the controller's kernel module. PS: While "AMD RAID" in recent Ryzen boards is also an example for "fake raid", it requires an own kernel module like if you have a real hardware controller. No dmraid option is needed.
