I am having the worse time trying to get OP25 to completely build. I am not sure if cmake is the issue. CMAKE v3.13.3. LUBUNTU 18.10 is the distro. I am begging for help to make this work.

Here is the screen output

I'm getting the same exact issue trying to compile on a raspberry pi 3. It doesn't matter if I follow the build instructions or just use the script.

Have you tried running the script with sudo?

Have you tried running the script with sudo?

Tried running the script with sudo and with root and still got the same results.

I went ahead and checked out older commits and was able to get it to build. Specifically with c292bc1 and e5e8fe so something after those is causing the issue.

It's possible it's an issue with the osmocom source, because I get the same error if I clone that repo and try to build too.

Same error for me (w ArchLinux):

whether script or by hand I tried bumping back to the commit levels sirrkitt had success with but no profit or joy

this on a freshly upgraded to Buster _Linux desk 4.19.0-5-amd64 #1 SMP Debian 4.19.37-5+deb10u2 (2019-08-08) x8664 GNU/Linux

I ended up doing a full removal of CMAKE 3.13.3 then installing CMAKE 3.10.3 from source. worked.

I stepped back in CMAKE versions to see when it would start compling right
and just as simplio I had to go back to cmake-3.10.3 to get it working
now I can reinstall 3.13 from the repo
I guess it would just be a matter of pointing things to the version I want to use
but I am not that smart so yes something is amiss

You don't have to uninstall the cmake that comes with your distribution. Just get the source for cmake 3.10.3, compile it but don't run 'make install'.
When configuring op25 build, run cmake with the explicit path to the cmake 3.10.3 binary; instead of calling the distro's cmake in the path. If you use the install.sh script, edit the 'cmake ../' line to do the same.

Probably not just Cmake maybe GNU make as well because of the warnings that pop up when there shouldn't be during making the o files or CMAKE didn't do something right. Shouldn't be errors nor warnings. If we knew the intended version or original version of Cmake make and Fortran used since OP25 was created maybe everyone can get things working a little better.

I am convinced with each update of Cmake things start breaking.

I do see changes in the SWIG modules between 3.12.4 and 3.13.0. I'll try bisecting it here once I've gotten a working 3.12-based build and reproduced the 3.13 error.

Notes:

dependencies not checked for by CMake:
- pcap
- itpp
find_package(REQUIRED) is preferred to find_package() / if (NOT FOUND) / message(ERROR) because find_package(REQUIRED) generally gives better error messages.
I was able to reproduce the error on 3.12.4 by doing a parallel build
Actually, the serial build has the same problem
Tentative conclusion: not a bug that 3.13 introduced (but it may have exposed it)

Running with Ninja as the generator shows this warning:

CMake Warning (dev):
  Policy CMP0058 is not set: Ninja requires custom command byproducts to be
  explicit.  Run "cmake --help-policy CMP0058" for policy details.  Use the
  cmake_policy command to set the policy and suppress this warning.

  This project specifies custom command DEPENDS on files in the build tree
  that are not specified as the OUTPUT or BYPRODUCTS of any
  add_custom_command or add_custom_target:

   op25/gr-op25/swig/op25_swig_doc.i
   op25/gr-op25_repeater/swig/op25_repeater_swig_doc.i

  For compatibility with versions of CMake that did not have the BYPRODUCTS
  option, CMake is generating phony rules for such files to convince 'ninja'
  to build.

  Project authors should add the missing BYPRODUCTS or OUTPUT options to the
  custom commands that produce these files.
This warning is for project developers.  Use -Wno-dev to suppress it.

Which is a problem that should be addressed, but doesn't seem directly related to the files mentioned in this issue. Other than that, the build with ninja completes. So not the dependency issue I thought it might be.

Looking at the difference, it seems to be a bug in UseSwig.cmake. Specifically, this logic:

  if(CMAKE_GENERATOR MATCHES "Make")
    __swig_compute_timestamp(${name} ${SWIG_MODULE_${name}_LANGUAGE}
      "${infile}" "${workingdir}" swig_generated_timestamp)
    set(swig_custom_output "${swig_generated_timestamp}")
    set(swig_custom_products
      BYPRODUCTS "${swig_generated_file_fullname}" ${swig_extra_generated_files})
    set(swig_timestamp_command
      COMMAND ${CMAKE_COMMAND} -E touch "${swig_generated_timestamp}")

The BYPRODUCTS list means nothing to non-Ninja generators, so it is meaningless if the generator matches Make. I think the fix may be to remove the IMPLICIT_DEPENDS CXX call and just add the outputs to the list of outputs (which is what I've usually done before). Removing BYPRODUCTS works at first glance, but likely will run afoul of the mentioned issue https://gitlab.kitware.com/cmake/cmake/issues/16830 in practice. Removing IMPLICIT_DEPENDS is likely to work, but also mean that the SWIG code is not built when it needs to be.

So, the solutions seem to involve, on the CMake side of things:

Remove BYPRODUCTS from the Make side of things.
Remove IMPLICIT_DEPENDS to avoid cmake#16830
Live with this deficiency in the Makefiles generators until it supports add_custom_command(DEPFILE) (and add this to UseSwig so that it works with the Ninja generator)

On the op25 side:

For Make-based generators, instead of depending on the py file, depend on ${swig_timestamp} instead of the ${swig_generated_source} Python file in cmake/Modules/GrPython.cmake:160 (and later add_custom_commands in that same function).

Actually, reading the comments again, it seems that 3.10 is the most recent working version. Between it and 3.11, I see this commit:

commit 2ee10119eac2802a234543581b1303d91b944afa
Author: Felix Schwitzer <flx107809@gmail.com>

    swig: fix incremental build in case of removed interface files

    Commit v3.8.0-rc1~123^2 (UseSWIG: Automatically scan dependencies of SWIG files
    for Makefiles, 2016-12-21) introduced automatic dependency scanning for files
    `%include`d in a swig interface definition file. This works fine as long as no
    such file is removed. But removing a dependent file breaks an incremental build
    and `make` complains about a missing dependency, see #16830.

    Integrate the approach proposed in the issue above into the SWIG-module, do the
    workaround in a conditional step as it arises only for Makefile generators. For
    other generators use the implementation before that commit.

    Fixes: #17433.

Commit: Kitware/CMake@2ee10119eac2802a234543581b1303d91b944afa
Issue: https://gitlab.kitware.com/cmake/cmake/issues/17433
MR: https://gitlab.kitware.com/cmake/cmake/merge_requests/1457

I'll file a new CMake issue to track this.

34 should fix this on the OP25 side (CMake still has an issue, but this workaround exists).

I'm still running into this issue... I tried downgrading to cmake 3.10, and didn't have any luck.
