LTLIBRARIES: mv * .Tpo * .Plo, but the former does not exist, and the latter already does

Question

I am doing a fairly direct conversion of an existing library (libtcod) to Autotools (for luck OS X). Unfortunately, when I switch the Makefile.am lib_LIBRARIES rule to lib_LTLIBRARIES , the assembly goes from successful to un. Excerpt from the result below:

 Making all in . make[1]: Nothing to be done for `all-am'. Making all in src /bin/sh ../libtool --tag=CC --mode=compile gcc -DHAVE_CONFIG_H -I. -g -O2 -MT bresenham_c.lo -MD -MP -MF .deps/bresenham_c.Tpo -c -o bresenham_c.lo bresenham_c.c mv -f .deps/bresenham_c.Tpo .deps/bresenham_c.Plo mv: rename .deps/bresenham_c.Tpo to .deps/bresenham_c.Plo: No such file or directory make[1]: *** [bresenham_c.lo] Error 1 make: *** [all-recursive] Error 1 

src/Makefile.am looks like this:

 lib_LTLIBRARIES = libtcod.la libtcod_la_SOURCES = bresenham_c.c bresenham3_c.c bsp_c.c color_c.c ... 

src/.deps contains:

 $ ls src/.deps/ bresenham_c.Plo bresenham_c.Po ... 

Am I making an obvious mistake here, or if it works?

Answer 1

Yes, I am making an obvious mistake. I needed to run autoreconf -i to create a non-empty ltmain.sh script; existing did ../libtool here no-op.
