July 24, 2016 command line option or other method for determining the front end version of gdc | ||||
---|---|---|---|---|
| ||||
One of my machines (running ubuntu mate 16.04) did some update and gdc is no longer able to compile a library that i like to use (gtkd). So i want to build a gdc using an earlier front-end to avoid the problem. However, i don't know what front end is compiled into gdc, so i'm unclear on which front-end to try get an earlier version of. If i run the command gdc --version it gives me the gcc version. The command gdc --verbose --version gives a lot more information, but i can't tell the front end version from that either. Even running commands like strings /usr/bin/gdc | grep ..... doesn't seem to reveal the version. (I think the version is probably 2.06* but '2.06' and '206' do not appear in the strings.) Nevertheless i'm sure the information must be there. TIA for any info! |

Later versions will write this out during compilation of a file under -v.
$ gdc -v test.d
# ...
version v2.068.2
# ...
For earlier versions, there is a universal way to do it in code.
pragma(msg, __VERSION__);

For reference, including that pragma causes the version (such as 2066L or 2067L) to be emitted during compilation. (And when i run it, i can see that 2067 is the offending version so at least i know what to try to roll back to.) dan |
