Description Tanu Kaskinen 2015-05-18 11:42:54 UTC

Commit 871dc461b1dfc431c0c95743af1624b781262bce upgraded libtool from 2.4.2 to 2.4.4, and after that it seems that libtool hasn't been able to build shared libraries on mips64. Or at least kmod's build system thinks that libtool isn't able to do that, and I also noticed earlier that alsa-lib is producing static libraries on mips64, causing QA warnings (I didn't investigate that further when I saw those warnings).

Trying to build kmod with MACHINE="qemumips64" fails in configure:

| checking if libtool supports shared libraries... no
| checking whether to build shared libraries... no
| checking whether to build static libraries... yes
| configure: error: --enable-static is not supported by kmod

Assigning to Khem, as instructed by Ross.

Comment 2 Tanu Kaskinen 2015-05-18 11:50:38 UTC

Sorry, I should have pasted a bit more of the configure output... The first message probably points towards the root cause:

Just tried this again with current master.

NOTE: Running .../mips64-poky-linux/kmod/21+gitAUTOINC+114ec87c85-r0/git/configure  --build=x86_64-linux --host=mips64-poky-linux --target=mips64-poky-linux
[...]

It appears that either libtool 2.4.6, or something else, fixed this.

I have built recently MIPS64 and works.
