[gentoo-user] Failed builds of kbuild and cdrdao with "undefined reference to `__alloca'"

[gentoo-user] Failed builds of kbuild and cdrdao with "undefined reference to `__alloca'"

[tuxic]

Hi,

I still have the problem of failed builds due to an
'undefined reference to `__alloca''. I recompiled 
gcc/glibc and I am using linux-4.15.1 (from kernel.org)
with linux-headers 4.15. .

Affected are (at least) cdrdao and kbuild.

For me "alloca" (memory allocation_) seems to be quite fundamental
and if this would really be not availlable I think a lot more
builds would fail...

I am using gcc (Gentoo 7.3.0 p1.0) 7.3.0. I recompiled glibc.
I did https://wiki.gentoo.org/wiki/Upgrading_GCC

What can cause this problem and how can I fix it?

Cheers
Meino

To make progress against this, you'll have to look at the build logs, or
let others look at them.

Before doing that, I would try to build the affected packages outside of
portage, saving the output of "configure" and "make".  If you also see
the problem that way, try with the stable gcc and compare logs.

BTW alloca() is a very peculiar way of allocating memory and only a few
packages use it, fortunately.

What's your sys-libs/glibc ?!

Heh, guessed so. Welcome to the wonderful world of early testing. 

It will take some time until the rest of Gentoo catches up with the changes in 
glibc-2.27 (and later). 

In the meantime I suggest you file bug reports (with Gentoo, and if there's no 
newer upstream version yet, also with upstream). Patches will eventually 
materialize.

Please always indicate clearly which version of glibc (i.e., either the 
version, or in case of 9999, the commit or precise date/time).

[Just for the record, running glibc-9999 on your main system is in my opinion 
crazy. And I package that thing.]

alloca() is usually handled by the compiler, so if there is sucvh a problem, 
this may be a result of incorrect include files that do not match the compiler.

BTW: cdrdao is unmaintained since aprox. 10 years and did not get any change 
since 8.5 years.

Hi Jörg,

what do you recommend to replace cdrdao?
