Hi,
I have a project with a libtool archive built from many source files.
When I build with 'make -j40' I get error message
mv: `yat/statistics/.deps/Percentiler.Tpo' and
`yat/statistics/.deps/Percentiler.Plo' are the same file
make[1]: *** [yat/statistics/Percentiler.lo] Error 1
Looks like some kind of race problem, but I cannot see anything wrong
in the Makefile. Is this a known problem? If not let me know what
would be useful.
I forgot to mention that the source file in question, 'Percentiler.cc',
is extremely small (only a constructor that copies a bool and a double)
so the compilation is extremely fast.
Cheers,
