gflags @2.1.2 issues while running (against facebook folly)

[georgemp@…]

Hi,

When trying to compile facebook folly against the latest gflags (on OS X 10.11.3), I run into the following error

ERROR: something wrong with flag 'flagfile' in file '/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_relea
se_tarballs_ports_devel_gflags/gflags/work/gflags-2.1.2/src/gflags.cc'. 

After uninstalling gflags @2.1.2 and installing 2.0_0 version, the error goes away. If there are any other troubleshooting steps you would like me to perform, please let me know.

I see a similar issue at ​https://groups.google.com/forum/#!topic/theia-vision-library/V2kufHCbNcY (not sure if the root cause is the same as what I am seeing).

Thanks

I should have mentioned - Facebook folly is at ​https://github.com/facebook/folly

In the future, please use WikiFormatting and Cc the port maintainers (port info --maintainers gflags), if any.

The README.md for 2.1.2 says they changed a lot of API issues which is likely the issue here. For now, just use 2.0 as you are until this can be fixed.
