Package: gdc Version: 4:9.2.1-3.1 Severity: normal According to man page for gdc(1):
-debuglib Specify the debug library to use instead of libphobos when linking. This option has no effect unless the -g option was also given on the command line. Options specifying the linkage of libphobos, such as -static-libphobos or -shared-libphobos, are ignored. $ gdc -debuglib -Wall -ggdb -O2 search.d d21: warning: unrecognized gcc debugging option: e d21: warning: unrecognized gcc debugging option: b d21: warning: unrecognized gcc debugging option: u d21: warning: unrecognized gcc debugging option: g d21: warning: unrecognized gcc debugging option: l d21: warning: unrecognized gcc debugging option: i d21: warning: unrecognized gcc debugging option: b $ AFAIK Debian doesn't provide the debug library (phobos and druntime compiled with debug options and extra debug assertions and unittest). libgphobos76-dbgsym is not a 'debug library', these are debug symbols for normal (optimized) phobos and druntime library. Even then, the -debuglib should be regognized, or maybe removed from the manpage for gdc(1) and gdc-9(1)? I can't find any info about -debuglib in gdc --help=common or in gdc --help=d. https://wiki.dlang.org/Using_GDC lists that there is option -debuglib=<path> dmd-script supposedly also supports it https://github.com/D-Programming-GDC/gdmd/blob/master/dmd-script I also looked at upstreadm GCC sources, and it should be supported: https://gcc.gnu.org/git/?p=gcc.git;a=blob;f=gcc/d/d-spec.cc;h=f4744763ab617e3adf762ca0a791a512597b0fa8;hb=HEAD#l172 But reading the source and reading between the lines of the manpage, maybe it should be stated in the manpage as '-debuglib libname', similar to '-defaultlib libname'?
