I installed the necessary packages on Cygwin and I'm trying to compile the
source files, but it cannot find the ICONV after I installed libiconv.

The text was updated successfully, but these errors were encountered:

I have this error on freebsd 10.3 also:

@joenio did you install libiconv (development version for the .h file) on a standard place?

albert-github · 2019-08-03T17:57:40Z

I recently installed doxygen (development) on a system with Cygwin and also installed libiconv (after I first missed it) and had no problems.

joenio · 2019-08-03T18:04:45Z

I have libiconv installed by the system package:

Description    :
This library provides an iconv() implementation, for use on systems which
don't have one, or whose implementation cannot convert from/to Unicode.

It can convert from any of these encodings to any other, through Unicode
conversion. It has also some limited support for transliteration, i.e.
when a character cannot be represented in the target character set, it can
be approximated through one or several similarly looking characters.

libiconv is for you if your application needs to support multiple character
encodings, but that support lacks from your system.

See either README or website for the list of supported encodings.

I'm not sure, but maybe the Find for Iconv doesn't like the local directory (I think the FindIconv.cmake on the cmake directory of doxygen is used).

Some alternatives:

In the FindIconv.cmake I saw:
```
find_path(ICONV_INCLUDE_DIR iconv.h
  HINTS
  ${CMAKE_PREFIX_PATH}
  ${ICONV_DIR}
  $ENV{ICONV_DIR}
  PATH_SUFFIXES include
)
```
So maybe the environment setting of ICONV_DIR to /usr/local or /usr/local/include might help.
See also FindSQLite3.cmake where some explicit paths are set.
What happens when you create symbolic links of the mentioned files in the /usr/local/lib/ and /usr/local/include/ to /usr/lib/ and /usr/include.
Another alternative might be to set ICONV_INCLUDE_DIR and ICONV_LIBRARIES.
I did a quick google and in another github repository I saw:

It seems you can fix it easily by setting the CMAKE_REQUIRED_INCLUDES variable to /usr/local/include before running the check_include_files.
See below:
http://www.cmake.org/cmake/help/v3.0/module/CheckIncludeFile.html?highlight=cmake_required_includes

I tried also:

cmake -G "Unix Makefiles" -DCMAKE_REQUIRED_INCLUDES=/usr/local/include/

I'm following try to solve this...

joenio · 2019-08-03T21:57:40Z

I guess the problem is with clang compiler, have you ever success compiling doxygen with clang instead of gcc?

albert-github · 2019-08-04T08:26:56Z

I myself didn't use the clang compiler.

I checked for a Find_Iconv (google: find iconv cmake) and found https://github.com/Kitware/CMake/blob/master/Modules/FindIconv.cmake and its documentation https://cmake.org/cmake/help/git-stage/module/FindIconv.html maybe you can use this file instead of the one provided by doxygen.

In your log file I see:
/usr/bin/c++ -I/usr/local/include -DICONV_COMPILES -o CMakeFiles/cmTC_b3571.dir/src.cxx.o -c /root/doxygen-master/CMakeFiles/CMakeTmp/src.cxx
and this indicates a bit to me that a library is missing. The /usr/local/include indicates that the include file path is OK. Maybe you have to do something with the ICONV_LIBRARY (though I never needed to do something with it).

I also see that the first message is about pthread, did yo google for solutions of e.g. "determining if the pthread_create exist failed with the following output"?

Please also post the complete terminal output of the cmake -G "Unix Makefiles" ...... and the complete CMakeError.log (as a .zip or .tar.gz file)

doxygen · 2019-08-04T09:04:51Z

@joenio I use clang on MacOSX without problems. I think the problem is your installation. pthread and iconv can be part of libc on some systems, or need to be linked explicitly on other systems. The cmake scripts try to detect what the configuration is, but somehow fail on your system, i.e. they try to link pthread but fail to find it (maybe because it is already part of libc) and they don't link iconv, but that causes an unresolved symbol (so it probably needed to be linked separately).

So I don't think this is a doxygen specific issue.

joenio · 2019-08-04T16:05:31Z

in fact, it's not a doxygen issue, it's a freebsd 10.3 issue, I discovered that the system has 2 libiconv.h installed, one at /usr/local/include/ and other at /usr/include/, I removed one at /usr/local/include/ (provided by libiconv) and cmake works as expected.

pkg remove libiconv
pkg remove iconv

but my real issue is to fix the cpantester building where I have no way to remove or install anything by hand (joenio/alien-doxyparse#1), that way I found a cmake flag to do the job without removing libiconv myself, CMAKE_IGNORE_PATH variable, that way I can ignore /usr/local/include path.

cmake -G "Unix Makefiles" -DCMAKE_IGNORE_PATH=/usr/local/include/

before, I reinstalled libiconv package and all works well

pkg install libiconv

I'm going to fix alien-doxyparse Perl package to add that cmake flag CMAKE_IGNORE_PATH, I hope it will works as expected.

thanks @doxygen and @albert-github for the help!

albert-github · 2019-08-04T16:16:49Z

Seen the comments I think the original problem does not exist anymore and the problem of joenio is a non doxygen problem, so the issue can be closed.
