To dmd developers: I have found a number of bug reports (e.g., <https://issues.dlang.org/show_bug.cgi?id=7678> and <https://issues.dlang.org/show_bug.cgi?id=17390>) concerning the issue of implementing for the dmd compiler the equivalent of the existing ldc2 -Xcc option to allow communicating options directly to the C compiler that is actually used by dmd (according to its -v option) for linking.
I would like to add my opinion that it would be good to get this requested -Xcc option implemented for dmd because of the following use case concerning -pthread (a common linking option used by many compilers to help arrange all the details correctly for linking the thread library). That use case is the PLplot project CMake-based build system for the static PLplot libraries case necessarily links its D plotting examples by linking a mixture of C-compiled code from the static plplot core C library, D-compiled code from the static plplotdmd library that implements the D binding for that C library, and the D-compiled code from the D example. This all works well for our CMake-based build system except for a fairly common configuration of our C library where the C code of that library must be linked with the -pthread compiler option when that C compiler is *used for linking*. So this all works well for the gdc compiler when it is used to link the D examples because it understands that -pthread option. And it also works well for ldc2 if the -Xcc-pthread option is used to inform the underlying C compiler used for linking of that -pthread option. However, that -Xcc option is currently not available for dmd (as far as I can tell from the above bug reports and from my attempts to use that option with a dmd compiler that I built myself on Linux) so I am pretty much stuck for this use case and dmd until the -Xcc option becomes available for the dmd case as well. Anyhow, thanks for listening to my request to implement the -Xcc option for the dmd compiler, and best wishes for your on-going development of dmd. Alan __________________________ Alan W.
