ftgl fails to link due to undefined symbols

[hellhovnd (Jean-Pierre Chauvel)]

Using macports from source (master commit 652c0b2aa03562ff4c1cdbb1676994b5a6886624) on Big Sur with Command Line Tools for Xcode 12 beta 5

[chrstphrchvz (Christopher Chavez)]

I haven't managed to reproduce this on macOS 10.15; I get other errors instead. My guess is that this port should be linking with -framework GLUT.

[chrstphrchvz (Christopher Chavez)]

Sorry, the port now builds for me without errors. (I can no longer reproduce the errors I initially encountered: libtool saying unknown tag CXX, and a linking command failing because it used clang instead of clang++.)

Any workaround?

I need ftgl for installing gnuplot +aquaterm+luaterm+pangocairo+qt+wxwidgets+x11.

[ryandesign (Ryan Carsten Schmidt)]

Since we're talking about macOS 11 here and the log mentions libtool, it seems likely that this is the well-known libtool bug when running on macOS 11+ and it needs the standard fix from the libtool port's files directory. Let me take a look.

[ryandesign (Ryan Carsten Schmidt)]

Unfortunately it's not that easy fix. This port already regenerates the configure script so it already contains the fixes from the libtool port.

[chrstphrchvz (Christopher Chavez)]

PR opened to manually append -framework GLUT to LDFLAGS, which I believe will work: ​https://github.com/macports/macports-ports/pull/9991 (Edit: rejected in favor of better fix)

[ryandesign (Ryan Carsten Schmidt)]

The port deliberately wanted to prevent the use of GLUT since it was only needed for examples. There were a couple bugs in the upstream source that I've fixed and some warnings I've suppressed.

[ryandesign (Ryan Carsten Schmidt)]

In 0113e27a0056a2e458c33b719b998796b6bb7f69/macports-ports (master):

ftgl: Fix warnings and build failure on Big Sur

Add configure args to ensure we always use macOS OpenGL framework not
MacPorts mesa.

Add patches to fix upstream bugs in handling configure args and
libGL.dylib.

Specify path to glibtoolize to avoid erroneous warning from autogen.sh.

Use compiler.cxx_standard 2011 instead of cxx11 1.1 portgroup.

Suppress OpenGL deprecation warnings.

Because I'm not confident that files from MacPorts mesa could not have
been used before, increase revision to rebuild.

Closes: #61210

[ryandesign (Ryan Carsten Schmidt)]

Sorry about the collision, Christopher. Guess we were both working on it at the same time. Hope it's alright that I went ahead with my version.

[chrstphrchvz (Christopher Chavez)]

No worries, I simply never got around to proposing the workaround sooner; glad that it isn't needed after all. Thanks also to the reporter who sent us a reminder.
