Created attachment 13714 [details] Output from configure and make So I tried to build gdb from scratch on my windows box using msys. The final lines that was reported before exiting to the command prompt were: CXXLD gdb.exe C:/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/10.3.0/../../../../x86_64-w64-mingw32/bin/ld.exe: C:/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/10.3.0/../../../../lib/libncursesw.a(lib_termcap.o):(.bss+0x8): multiple definition of `UP'; ../readline/readline/libreadline.a(terminal.o):C:/msys64/mingw64/include/termcap.h:35: first defined here C:/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/10.3.0/../../../../x86_64-w64-mingw32/bin/ld.exe: C:/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/10.3.0/../../../../lib/libncursesw.a(lib_termcap.o):(.bss+0x0): multiple definition of `BC'; ../readline/readline/libreadline.a(terminal.o):C:/msys64/mingw64/include/termcap.h:36: first defined here C:/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/10.3.0/../../../../x86_64-w64-mingw32/bin/ld.exe: C:/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/10.3.0/../../../../lib/libncursesw.a(lib_tputs.o):(.bss+0x6): multiple definition of `PC'; ../readline/readline/libreadline.a(terminal.o):C:/msys64/mingw64/include/termcap.h:29: first defined here collect2.exe: error: ld returned 1 exit status make[2]: *** [Makefile:1882: gdb.exe] Error 1 make[2]: Leaving directory '/tmp/build/gdb' make[1]: *** [Makefile:10462: all-gdb] Error 2 make[1]: Leaving directory '/tmp/build' make: *** [Makefile:915: all] Error 2 I've attached a file showing the configure and build output. What's going on? I also tried to build 10.2 with the same problem.
Moving to build. Offhand I don't know what's going wrong here, sorry. I guess I'd investigate why these symbols are being defined in readline. Or maybe disable readline or try the system readline, if you have one available.
