glm @0.9.9.0: build fails on 10.8 and earlier

[dbevans (David B. Evans)]

Apparently a compiler issue:

Home page says:

GLM is written in C++98 but can take advantage of C++11 when supported by the compiler.

Possibly using the cxx11 1.1 PortGroup would solve the problem.

Probably. On my 10.6.8 / libc++ system that builds everything with clang-3.9, it installed without issue:

$ port -v installed glm
The following ports are currently installed:
  glm @0.9.9.0_0 (active) platform='darwin 10' archs='noarch' date='2018-07-13T16:12:25-0700'

[kencu (Ken)]

the current version of this 0.9.9.4 crashes the linker ld64-latest when building with the cxx11 1.1 PG against macports-libstdc++ (in c++11 mode).

The non-c++11 version builds fine.

this is the crashlog trying to build glm against macports-libstdc++ with clang-5.0 on 10.7.5

In f5c5cb94db3fd66a88b13bdf0519bfe78bdee4c5/macports-ports (master):

glm: bump to 0.9.9.4 and fix build on older systems

requires newer compilers, clang-3.4+, clang > 600.
cxx11 1.1 PG cannot fix this right now as linker segfaults
when trying to link this against macports-libstdc++

closes: #57085

Some kind of bizarre error on the 10.7.5 buildbot:

but it builds just fine on 10.7.5 right here with the same compiler, and on other systems:

$ port -v installed glm
The following ports are currently installed:
  glm @0.9.9.3_0 platform='darwin 11' archs='noarch' date='2019-03-22T12:31:58-0600'

Fixed by rebooting that buildworker.

thanks Ryan.
