DOC Build Errors (convert & latex)

[jacobfriedman]

The default build includes a doc-required command convert - please advise; thanks in advance.

(cd ../doc; make all)
make[1]: Entering directory '/home/jacob/projects/gprolog/doc'
convert -scale 150x150 ../gprolog.ico[5] logo.eps
/bin/sh: 1: convert: not found
make[1]: *** [Makefile:75: logo.eps] Error 127
make[1]: Leaving directory '/home/jacob/projects/gprolog/doc'
make: *** [Makefile:54: doc] Error 2

Paulo Moura from Logtalk correctly suggested I install imagemagick.

I'm now getting this out-of-the-box:

(cd /usr/local/gprolog-1.5.0/lib; for i in *.a; do ranlib $i; done)
(cd ../doc; make all)
make[1]: Entering directory 'gprolog/doc'
convert -scale 150x150 ../gprolog.ico[5] logo.eps

Latex is also needed for the docs, I guess.
pdfTeX 3.14159265-2.6-1.40.20 (TeX Live 2019/Debian) not working:

! LaTeX Error: Cannot determine size of graphic in logo.eps (no BoundingBox).

./configure --without-doc-dir --without-html-dir still builds the docs:

CLOSED
this requires an extra texlive package (ubuntu 19/20):
apt-get install texlive texlive-latex-extra hevea imagemagick
Make sure you get imagemagick >= 6.11 (I got 7)

Hi Jacob,
the git repo only contains "sources" (most of "target" files are not present and must be built).
The doc is only needed when you do a 'make install'.
BTW: if you don't need to install gprolog, you can execute the locally compiled version with an adequate PATH. Under bash you can use the SETVARS script:

cd src
. SETVARS
make
gprolog

Doing this, there is no need to install gprolog (and thus to compile the doc). To compile the doc, you need the convert utility (from ImageMagick) to create logo files. It is extracted from the icon file (with an index). There is a version of ImageMagick containing a bug on the index of the icon to extract (some versions seem to count from 0, others from 1). Anyway, I plan to add the logo files so convert will not be needed. However, you need LaTeX and HeVeA.
