Compilation of documentation fails in case of compilation from tarball.

Compilation of documentation fails in case of compilation from tarball.

make: Entering directory 'T/form-4.3.1/doc'
Making pdf in doxygen
make[1]: Entering directory 'T/form-4.3.1/doc/doxygen'
[ -f version.sh ] || ln -s "./version.sh.in" version.sh
Running /usr/bin/doxygen DoxyfilePDFLATEX ...
/bin/sh: line 2: ./version.sh: No such file or directory
make[1]: *** [Makefile:555: pdflatex/doxygen.tex] Error 1
make[1]: Leaving directory 'T/form-4.3.1/doc/doxygen'
make: *** [Makefile:423: pdf-recursive] Error 1
make: Leaving directory 'T/form-4.3.1/doc'

Expected result: compilation of docs from the tarball suceeds.

The way to reproduce:

mkdir T
cd T
wget https://github.com/vermaseren/form/releases/download/v4.3.1/form-4.3.1.tar.gz
tar zxfv form-4.3.1.tar.gz 
cd form-4.3.1/
autoreconf -fi
 ./configure
make -j 10 
make -C doc pdf

Thank you for your report. I think I know what is happening with the tarball.

In Makefile.am for Doxygen, almost everything is included in an if CONFIG_DOXYGEN clause. This means that the version information file for Doxygen is included to a tarball only when Doxygen is available/enabled. And, the tarball was generated with Github Actions, without Doxygen.

I also found that the fallback in configure.ac does not consider Doxygen.

I will fix these issues. For now, a workaround would be:

touch doc/doxygen/version.sh.in
