Package: user-mode-linux
Version: 2.6.25-1um-1
Severity: serious
Tags: patch
Justification: no longer builds from source
user-mode-linux fails to build on amd64 with the following error:
| CC arch/um/sys-x86_64/ksyms.o
| arch/um/sys-x86_64/ksyms.c:16: error: '__memcpy' undeclared here (not in a
function)
| arch/um/sys-x86_64/ksyms.c:16: warning: type defaults to 'int' in declaration
of '__memcpy'
| make[2]: *** [arch/um/sys-x86_64/ksyms.o] Error 1
| make[1]: *** [arch/um/sys-x86_64] Error 2
The problem is that arch/um/sys-x86_64/ksyms.c unconditionally tries
to export __memcpy even though include/asm-x86/string_64.h declares it
only for GCC 4.2 and older, newer versions presumably being smart
enough not to need it. I'm attaching a patch that conditionalizes the
EXPORT_SYMBOL call accordingly, and have confirmed that it allows the
build to complete without errors. (FTR, arch/um/os-Linux/user_syms.c
already exports memcpy itself, so ksyms.c need not do so in any case.)
FWIW, you can find a full log illustrating the error at
