Adding extra rules to make

[jcurlmail]

Hello,

As part of the build process, I would like to convert text files to binary 
files. They don't get installed, the files can be used later to test the 
program.

In particular, the input format is *.txt and the output format is *.bin.

I've got it working, but I feel it's far from elegant. I want it to be part of 
the distribution package, the .bin files to be generated by the source .txt 
files but I don't want them to be installed anywhere.

Thanks,
Jason.

Makefile.am
SRC = 01_InvalidByte.txt      \
      02_CorruptedMsg.txt     \
      03_InvalidByte.txt      \
      04_InvalidByteAscii.txt \
      05_BufferOverrun.txt

# The rule:
#   BIN = $(SRC:.txt=.bin)
# doesn't seem to work
BIN = 01_InvalidByte.bin      \
      02_CorruptedMsg.bin     \
      03_InvalidByte.bin      \
      04_InvalidByteAscii.bin \
      05_BufferOverrun.bin

CLEANFILES = $(BIN)

EXTRA_DIST = $(SRC) pxxd.pl

all: $(BIN)

# When we 'make' we create generate the bin files
.txt.bin: 
        perl pxxd.pl $< $@
