Hello Vincent,

With MSYS, noinst_PROGRAMS is set to

cmapdump$(EXEEXT) fontdump$(EXEEXT)

but BUILT_SOURCES is set to

cmapdump fontdump

Is it normal that BUILT_SOURCES does not try to see if they are
binaries in some variables ?

I don't think we've come across an example where it was necessary to put
compiled programs into BUILT_SOURCES.  For one, that would mean that
cross compilation will not work.  For another: can you please explain
what you are trying to achieve?  I'm sure there is another way.

I am building a library that is using mupdf. I have autotooled mupdf for my personal project. mupdf is splitted into several libraries:

libfitz libdraw libcmaps libfonts libmupdf

libcmaps source files are generated by a binary named cmapdump.

So I have something like:

noinst_PROGRAMS = cmapdump
cmapdump_SOURCES = mupdf-0.7/mupdf/cmapdump.c



cmap_tounicode_files = \
mupdf-0.7/cmaps/Adobe-CNS1-UCS2 \
mupdf-0.7/cmaps/Adobe-GB1-UCS2 \
mupdf-0.7/cmaps/Adobe-Japan1-UCS2 \

libcmaps_la_SOURCES = cmap_tounicode.c
cmap_tounicode.c: cmapdump $(cmap_tounicode_files)
        ./cmapdump $@ $(cmap_tounicode_files)

If I don't use BUILT_SOURCES, cmapdump binary is not built before libcmaps, hence cmap_tounicode.c is not created, and compilation of libcmaps fails.

Is there another solution ?

Other than that, you're right: automatic $(EXEEXT) appending is not done


thank you
