Wireshark-dev: Re: [Wireshark-dev] Attempted to build NSIS installer for 2.6.3

I've been able to whittle my issue down to a specific spot in the build process.  For those trying to follow, I'm trying to build
2.6.3 on Windows in Cygwin (since I don't have control of the build environment).  I've been able to install an asciidoctor
program on Cygwin64 when ruby and rubygems package is installed through setup-x86_64.exe using

gem install asciidoctor
cp ~/bin/asciidoctor /bin

Then, I see that FindAsciidoctor is only supporting Chocolatey.  I compare against FindYACC which does work with my
Cygwin64 installation to FindAsciidoctor.

I add the following statements to FindAsciidoctor

#
# - Find Asciidoctor
# Sets:
#  ASCIIDOCTOR_EXECUTABLE
#

+INCLUDE(FindCygwin)
INCLUDE(FindChocolatey)

FIND_PROGRAM(ASCIIDOCTOR_EXECUTABLE
    NAMES
        asciidoctorj
        asciidoctor
    PATHS
        /bin
        /usr/bin
        /usr/local/bin
+      ${CYGWIN_INSTALL_PATH}/bin
        ${CHOCOLATEY_BIN_PATH}
    DOC "Path to Asciidoctor or AsciidoctorJ"
)

if(ASCIIDOCTOR_EXECUTABLE)
    # The AsciidctorJ wrapper script sets -Xmx256m. This isn't enough
    # for the User's Guide.
    set(_asciidoctorj_opts -Xmx800m $ENV{ASCIIDOCTORJ_OPTS})
    execute_process( COMMAND ${ASCIIDOCTOR_EXECUTABLE} --version OUTPUT_VARIABLE _ad_full_version )
    separate_arguments(_ad_full_version)
    list(GET _ad_full_version 1 ASCIIDOCTOR_VERSION)

    function(set_asciidoctor_target_properties _target)
    ...

At the 'list(GET _ad_full_version 1 ASCIIDOCTOR_VERSION)' command, I get a cmake error because the previous execute_process
command produces an _ad_full_version that's empty.  When I run 'asciidoctor --version' in my Cygwin prompt, I get

Asciidoctor 1.5.7.1 [https://asciidoctor.org]
Runtime Environment (ruby 2.3.6p384 (2017-12-14 revision 9808) [x86_64-cygwin])
(lc:UTF-8 fs:Windows-1252 in:UTF-8 ex:UTF-8)

If I put in a 'message( "ASCIIDOCTOR_EXECUTABLE " ${ASCIIDOCTOR_EXECUTABLE} )' I get something that looks like this

-- ZLIB libs: zlib
ASCIIDOCTOR_EXECUTABLE C:/cygwin64/bin/asciidoctor
CMake Error at cmake/modules/FindAsciidoctor.cmake:30 (list):
  list GET given empty list
Call Stack (most recent call first):
  docbook/CMakeLists.txt:15 (find_package)

I don't know exactly how execute_process is trying to run the asciidoctor program.

Any ideas why this execute_process CMake command isn't working?

Thanks,
John D.

As far as I understand it used to in the past, though it seems to have moved on from it.  I'm trying to update my local repo from
Wireshark 2.4.4 where my environment used to work fine to the current branch of 2.6.3.

asciidoctor after setup_x86_64.exe for installing cygwin64 returns a '-bash: asciidoctor: command not found' cause there is no
package to install asciidoctor at least from the Cygwin setup-x86_64.exe program.

I know I selected docbook-xml45, but don't think I specifically picked up libxslt directly.  It may have been installed as a dependency.

The cmake script can find the following components

-- Could NOT find ASCIIDOCTOR (missing:  ASCIIDOCTOR_EXECUTABLE)
-- Found XSLTPROC: C:/cygwin64/bin/xsltproc.exe
-- Found HTMLHelp: C:/Program Files (x86)/HTML Help Workshop/hhc.exe

I'd have to get Chocolately approved by govt IT and not sure if or how long that would take.  Wouldn't be a problem if this was
for personal use.

I can use 'gem install asciidoctor' to create an asciidoctor and asciidoctor-safe that is placed in a local /bin directory in the user's
/home in Cygwin and when I run that '~/bin/asciidoctor --version' I get

Asciidoctor 1.5.7.1 [https://asciidoctor.org]
Runtime Environment (ruby 2.3.6p384 (2017-12-14 revision 9808) [x86_64-cygwin])
(lc:UTF-8 fs:Windows-1252 in:UTF-8 ex:UTF-8)

I believe this requires ruby and rubygems packages to be selected in Cygwin's setup-x86_64.exe program.

With admin privileges, I can move this to C:\cygwin64\bin so I can run asciidoctor --version from a cygwin prompt, but when I
run the CMake command, build script still doesn't find it.  Curious since it finds

-- YACC FOUND
-- YACC executable: C:/cygwin64/bin/bison.exe

And asciidoctor is in the same folder.

Comparing FindYACC.cmake and FindAsciidoctor.cmake shows that YACC has ${CYGWIN_INSTALL_PATH}/bin in its lists of
Paths.  Not sure why the directories in the FindYACC and FindAsciidoctor cmake scripts have different orders.

By adding '${CYGWIN_INSTALL_PATH}/bin' to FindAsciidoctor.cmake, cmake now finds asciidoctor.

-- Found ASCIIDOCTOR: C:/cygwin64/bin/asciidoctor

However, at the end of the script, it says Configuring incomplete, errors occurred!

Trying to run visual diff between CMakeOutput.log and CMakeError.log before I added ${CYGWIN_INSTALL_PATH}/bin to
FindAsciidoctor.cmake to after to try to see what's up.  Lots of diffs due to generated filenames, hard to make out what the
issue is.

That's where I'm at right now.

Thanks,
John D.
