           Summary: Build fail caused by ccache in module-init-tools
           Product: buildroot
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P4
         Component: Outdated package
        AssignedTo: unassigned at buildroot.uclibc.org
        ReportedBy: mjd-busybox.net at afork.com
                CC: buildroot at uclibc.org
   Estimated Hours: 0.0


I am having problems with the latest buildroot.  If I take a stock buildroot
checkout from git, run make menuconfig, then save and make, it compiles.  If I
then run make menuconfig, choose Kernel -> Kernel type -> linux (same version
as Linux headers), then do a make, the build fails.

The build fails when it tries to compile module-init-tools.  The makefiles call
/usr/lib/ccache/gcc, which fails saying "/usr/bin/ld: cannot find -lc".  Please
see attached build log.

The ccache setting was not changed, so it has the default value of unset.

mjd at milhouse ~/src/buildroot $ grep CCACHE .config
# BR2_CCACHE is not set
# BR2_PACKAGE_CCACHE_TARGET is not set
mjd at milhouse ~/src/buildroot $

This is because glibc static library is missing on the host.
On Fedora "yum install glibc-static" solves this problem.

However I admit that buildroot could check and report that you need to install
it.

Interesting.  Why is the host's static version of libc needed?

(And thanks for the workaround)

Or looking a little higher up the cause-of-failure tree, why is
module-init-tools being compiled with ccache (when it's turned off in the
config)?

Mitch, with the merge of the linux-cleanup work, the module-init-tools package
has been upgraded and migrated to the autotools infrastructure. So it is
possible that the problem you're seeing has been fixed.

Can you give a try at the latest Buildroot git ?

Hi, I'm getting this error:
make[2]: Entering directory
`buildroot/output/build/host-module-init-tools-3.11/build'
/usr/lib64/ccache/gcc  -Ibuildroot/output/host/include
-Ibuildroot/output/host/usr/include -Wunused -Wall -static
-Lbuildroot/output/host/lib -Lbuildroot/output/host/usr/lib
-Wl,-rpath,buildroot/output/host/usr/lib -o insmod.static insmod.o
libmodtools.a 
/usr/bin/ld: cannot find -lc
collect2: ld returned 1 exit status

with git and ccache enabled , and  yum install glibc-static , fixes the
problem.


but what should I do ? disable CCACHE or use glibc-static  ?

short of us hacking the module-init-tools makefile, it is building a static
version of insmod - So I would say install the glibc package.

The issue was in fact that glibc-static was missing on the user host system. We
have added a FAQ entry in Buildroot documentation to document this. See
http://git.buildroot.net/buildroot/commit/?id=706683b8b912aa3304d71652d7a4a74d8b74f58e
