tesseract @3.04.01: configure: error: leptonica not found

After solving (manually) the problems with openjpeg and openmp, this problem showed up in logfile /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_textproc_tesseract/tesseract/work/tesseract-3.04.01/config.log:

It's not clear why tesseract can't find leptonica on your system. The portion of the config.log you quoted is irrelevant to this issue.

Is leptonica installed? Does the file /opt/local/include/leptonica/allheaders.h exist? What's the output of these two commands:

port -vq installed leptonica
port -q contents leptonica

What problems with openjpeg and openmp are you referring to, and how did you solve them?

[cvdenzen]

The file /opt/local/include/leptonica/allheaders.h does not exist:

sh-3.2# ls -l /opt/local/include/leptonica/allheaders.h
ls: /opt/local/include/leptonica/allheaders.h: No such file or directory

The commands give this output:

sh-3.2# port -vq installed leptonica

I cannot remember what the symptoms of the problems with openjpeg and openmp were. I guess I saw errors mentioning these packages/header files.

I thought I solved the openjpeg problem in leptonica as described in #55283.

In my shell history I also see that I did cp /usr/local/lib/pkgconfig/lept.pc ./lib/pkgconfig/. I don't remember the reason for this. Trying to solve the error with openmp I did (as root) make a symlink in /opt/local/include/clang to omp.h:

pushd /opt/local/include/
mkdir clang
cd clang
ln -s /usr/local//Cellar/llvm/5.0.0/lib/clang/5.0.0/include/omp.h omp.h

Somehow your leptonica has decided to install itself into /usr/local instead of /opt/local like it should have. You've also got Homebrew installed into /usr/local, and that could be the reason for leptonica's misbehavior. Installing things into /usr/local is going to cause problems for MacPorts, as you see, which is why we don't support that. Please choose whether you would like to use Homebrew or MacPorts. If you would like to use MacPorts, please remove Homebrew and everything else you put in /usr/local, and also any headers or other random changes you made in /opt/local that are going to confuse MacPorts (or MacPorts developers when you report the resulting problems), then rebuild the leptonica port (i.e. sudo port -n upgrade --force leptonica) and any other ports that got misbuilt while the things were present in /usr/local.
