Build failure at "doc" generation rules to generate cloog.pdf for version 0.21.1

[pal-stdr]

While I was trying to build cloog-0.21.1, the build fails at doc/cloog.pdf generation from doc/cloog.texi file. I am using Ubuntu 20.04. Already I have opened a separate issue #50 for this.

The error message looks like following

This is pdfTeX, Version 3.14159265-2.6-1.40.20 (TeX Live 2019/Debian) (preloaded format=pdfetex)
 restricted \write18 enabled.
entering extended mode

.... bla bla bla

/usr/bin/texi2dvi: pdfetex exited with bad status, quitting.
make[1]: *** [Makefile:2303: doc/cloog.pdf] Error 1
make[1]: *** Waiting for unfinished jobs....
make[1]: Leaving directory '/home/pal-vbox/compiler-projects/cloog-0.21.1-test/build'
make: *** [Makefile:1581: all-recursive] Error 1

How to solve this issue? Thanks in advance!

Found a dirty way to solve this thing. The catch is, there will be no cloog.pdf for version 0.21.1.

How to:

• After cloning 0.21.1, open Makefile.am and remove the following doc: rule from line 178.

  
  doc:
  @echo "             /*-----------------------------------------------*"
  @echo "              *        Generating CLooG's documentation       *"
  @echo "              *-----------------------------------------------*/"
  doxygen ./autoconf/Doxyfile

/*****

Doc

*****/

if HAVE_TEXI2DVI pdf_DATA = doc/cloog.pdf dist_pdf_DATA = doc/cloog.pdf doc/cloog.pdf: doc/cloog.texi doc/gitversion.texi $(TEXI2DVI) -I $(top_builddir)/doc --pdf $< -o $@ endif

doc/gitversion.texi: @GIT_INDEX@ echo '@set VERSION '$(top_builddir)/genversion.sh'' > $@

- Then run the `autogen.sh` or the command `autoreconf -i` to generate the `configure` file.
