graphviz @2.40.1: libtool: compile: unable to infer tagged configuration

[TonyCrawford]

Tried after cleaning and reconfiguring; it's well stuck.

OS X 10.9.5;

Apple LLVM version 6.0 (clang-600.0.57) (based on LLVM 3.5svn);

Appending main.log and port -v installed;

here's the build command that seems to trip the error:

:info:build /bin/sh ../../libtool    --mode=compile /usr/bin/clang -DHAVE_CONFIG_H -I. -I../..  -I../.. -I../../lib/common -I../../lib/pathplan -I../../lib/gvc -I../../lib/cgraph -I../../lib/cdt  -I/opt/local/include -I/opt/local/include  -pipe -Os -arch x86_64 -MT GVTextLayout.lo -MD -MP -MF .deps/GVTextLayout.Tpo -c -o GVTextLayout.lo GVTextLayout.m

port -v installed output

That libtool invocation is indeed missing --tag=CC.

[cjones051073 (Chris Jones)]

works fine if you force use of macports clang 9.0

sudo port install graphviz configure.compiler=macports-clang-9.0

so adding a compiler blacklist to enforce this for the old OSes that are affected is an option to fix this.

[mkeller (Markus Keller)]

Replying to cjones051073:

works fine if you force use of macports clang 9.0

sudo port install graphviz configure.compiler=macports-clang-9.0

To recover from the broken state, you need to run this before installing again with the explicit compiler option as given above:

sudo port clean graphviz

Certainly I don't want to blacklist compilers just to fix this. The correct fix, as jmr already alluded, is to add the --tag=CC flag where it's needed. We are working on an update to graphviz 2.47.0. If that does not resolve the issue, then we'll patch it correctly and send the fix to the developers.

Has duplicate #62679.

It took me awhile to reacquaint myself with this error. We used to see a lot of "unable to infer tagged configuration" errors around ten years ago. That was when Apple switched compilers from gcc to briefly llvm-gcc and finally to clang. At that time, the error only seemed to occur if the compiler that had been used to make libtool was different from the compiler being used to compile something else (i.e. graphviz) with libtool now. I'm not certain whether that's the same thing that's happening now. We don't know what compiler the two reporters used when compiling their libtool, but the usual for OS X 10.9 would be to use the normal /usr/bin/clang, in which case the problem should not have occurred.

I was not able to reproduce the problem on my macOS 10.13 machine where both my libtool and graphviz were being compiled with /usr/bin/clang. I also couldn't reproduce the problem by trying to compile graphviz with a different (MacPorts clang) compiler. However we did recently reproduce the problem on a ​MacPorts automated build machine, and there again both libtool and graphviz were being compiled with the same compiler (/usr/bin/gcc-4.2 in that case).

I can however see that that --tag=CC is indeed missing when invoking libtool to compile GVTextLayout.m. It looks like upstream had tried to fix this problem five years ago however their fix contained two mistakes so it didn't work, and it doesn't appear to have been corrected yet in the current version. I've reported the problem to them and proposed a fix: ​https://gitlab.com/graphviz/graphviz/-/issues/2065
