[sheepdog-users] Compilation error of bundled lirbrary isa-l

[Marcin Mirosław]

Hello!
Please look at this error:

>>> Compiling source in /var/tmp/portage/net-fs/sheepdog-9999/work/sheepdog-9999 ...

Because isa-l is builded silently I can't see invocation of failing
command. Using "make -n" I suspect that it is:

mkdir -p bin
echo "  ---> Building erasure_code/ec_highlevel_func.c
/var/tmp/portage/net-fs/sheepdog-9999/image/"
gcc  -Wall  -O2 -D /var/tmp/portage/net-fs/sheepdog-9999/image/ -D
NDEBUG -Ierasure_code -Iinclude   -c -o bin/ec_highlevel_func.o
erasure_code/ec_highlevel_func.c

So wrong parametr is: "-D /var/tmp/portage/net-fs/sheepdog-9999/image/"
but I don't know why build system set such strange MACRO name.
