Unable to build OpenGLAda libraries. #80

Closed rogermc2 closed 7 years ago

rogermc2 commented 7 years ago

Suddenly my builds are failing when attempting to build OpenGLAda libraries. I tried on a couple of my branches with the same result.

gprbuild -d -eL -P/Ada_Source/OpenGLAda/opengl.gpr -XLIBRARY_TYPE=static -XAuto_Exceptions=enabled -XMode=release -XWindowing_System=quartz -s -XWindowing_System=quartz --create-missing-dirs --config=/Ada_Source/config.cgpr Build Libraries [gprlib] OpenGLAda.lexch gprlib: unknown section: [PROJECT DIRECTORY] gprbuild: could not build library for project opengl

I recently moved to GPS GPL 2016 which seems to be the problem. It worked OK for a few days then, today, this problem suddenly occurred. I reset the toolchain to /opt/gcc-6.1.0/bin and this fixed the problem. So there seems to be a problem with the GPS GPL 2016 gnat system?

2016 is not the recent release anyway, try with 2017.

Actually it is 2017, from Help -> about: GPS 2017 (20170515) hosted on x86_64-apple-darwin14.5.0 GNAT GPL 2017 (20170515-63) The Application name in the Mac menu line is GPS GPL 2016! Should be GPS GPL 2017?

flyx commented 7 years ago

Incompatibility with GNAT GPL 2017 is unfortunate, but we already have the incompatibility with GNAT GPL 2016 on OSX, so I guess it just continues a tradition.

For a more helpful comment: This error seems to stem from this line, maybe you can backtrack from there what's going wrong.

This part of the gprlib seems to read a library exchange file. It may well be that the format of those simply changed, and the error occurs when gprbuild tries to read an exchange file that was generated by a previous version. try to clean everything and compile anew.

I deleted the current /usr/local/gnat plus a few other associated things. Downloaded a fresh copy, installed and so far its working. The unarchived download is gnat-gpl-2017-x86_64-darwin-bin This is the same as the previous one that eventually failed; so its wait and see for a few days.

Clean and reinstall seems to have fixed the problem.

rogermc2 commented 7 years ago

Problem has reappeared and remains after deleting GNAT and reinstalling.
