Mac Framework not installing Libraries when using cmake

[Schamschula]

When I build Coin-4.0.0 using configure under MacPorts, I get

/opt/local/Library/Frameworks/Inventor.framework/Versions/D/Libraries/libCoin.80.0.0.dylib
/opt/local/Library/Frameworks/Inventor.framework/Versions/D/Libraries/libCoin.80.dylib
/opt/local/Library/Frameworks/Inventor.framework/Versions/D/Libraries/libCoin.dylib

while there is no such directory when building with cmake with

configure.args-append \
-DCOIN_BUILD_MAC_FRAMEWORK=ON \
-DCMAKE_INSTALL_PREFIX=${frameworks_dir}

all other files are installed correctly.

This is a blocker when trying to build SoQt, py-pivy and FreeCAD, as they are looking for the .cmake files.

Did you get any errors? What version of Darwin are you on? I just checked the latest sources on my VM with Mojave 10.14 and it built and installed without failure.
I used the instructions from the BuildWithCMake wiki page.
Can you provide the scripts you used for your MacPorts build?

[Schamschula]

My main build machine also is running Mojave.

I just had a look at the wiki page. Nothing particularly useful.

The first thing to note is that I get a configure error as downloading the source tarball from GitHub does not include the cpack.d directory. I commented it out from the CMakeLists.txt file as MacPorts takes care of packaging.

The second issue I ran into is

[ 86%] Linking CXX shared library ../lib/Inventor.framework/Inventor

which I can work around in testing, by manually running

sudo /opt/local/bin/cmake -E cmake_link_script CMakeFiles/Coin.dir/link.txt --verbose=ON

in that directory and then proceeding with the MacPorts build. It looks like a permissions issue.

The current state of the Portfile is in flux as I'm attempting to move from autotools to cmake. Yes, the homepage hasn't been updated and the manpages variant certainly wouldn't build under cmake. As I can't directly attach a Portfile, I've pasted it here.

Note: Coin builds and installs correctly, but the Coin-framework subport fails.

Thanks for reporting back.

Coin wiki Git section explains why downloading the source tarball from Releases won't work. Coin3D uses submodules all over its repositories and they won't be properly populated in the default Github generated source tarballs. Please use the CI generated source tarballs or zip files. Along those you'll find the md5 and sha256 checksum files to verify the downloads.

I was also facing the permissions issue as I am not permitted to install to /opt as a regular user. It needs administrative privileges to do so.

Man pages will be build properly if -DCOIN_BUILD_DOCUMENTATION=ON is added to the configure args in combination with -DCOIN_BUILD_DOCUMENTATION_MAN=ON. In the current sources the man page generation has been recently updated to generate uniquely named man pages (prefix them with coin_) so renaming them is not necessary anymore.

Expat may be added as additional dependency. Then -DUSE_EXTERNAL_EXPAT=ON needs to be added to the configure args.

Hope, that helps further for updating the macports port.

Unfortunately, downloading directly from a git repo is frowned upon by the MacPorts community, and is only used in -devel ports. A stable port should not have to pull in a number of sub-repos. Downloading and joining multiple sub-repos can be done manually, but that also means reproducing the github PortGroup functionality (an extreme example is the nginx Portfile).

I was not referring to installing in /opt, which is always done using sudo under MacPorts, but rather an issue during the build process, which is normally done w/o root privileges.

Since my last post I already figured out how to build the Documentation. However, I do not see the coin_ prefix on the man pages.

Thanks for the hint on expat!

"Unfortunately, downloading directly from a git repo is frowned upon by the MacPorts community, and is only used in -devel ports. A stable port should not have to pull in a number of sub-repos." Understandable from a package maintainers point of view.

I think I misunderstood or misinterpreted the installation issues as both builds, Coin 4.0.0 release and current Github coin repository went without issues as restricted user using a command line as given in the wiki. What CMake version and what Xcode version are you using? I used CMake 3.13.4 and Xcode 10.1 (A bit outdated, but it just works)

Are you building the coin 4.0.0 release? Then it's OK, it will not contain the man page fix. The fix has been only recently added. Time for a 4.0.1 release I think.

[Schamschula]

I tweaked the download to pull form releases rather than archive. Thus the patch to CMakeLists.txt is no longer needed, and the libraries get installed.

It turns out the issue with sh: /bin/ps: Operation not permitted only happens in trace mode (my default when test building, to pick up missing dependencies). I'll have to ask around to see how to deal with that.

[Schamschula]

Yes, I'm building the 4.0.0 release.

I just added a PR to macports to update Coin3d related port files (simage, Coin, SoQt, and Quarter) to their current versions.
