Just tried building GNU APL with 64-bit Cygwin on my Windows 10 Acer laptop.
It did not go well. $ make|grep error g++: error: unrecognized command line option '-rdynamic' make[3]: *** [template_F0.lo] Error 1 make[3]: *** Waiting for unfinished jobs.... g++: error: unrecognized command line option '-rdynamic' make[3]: *** [template_OP1.lo] Error 1 g++: error: unrecognized command line option '-rdynamic' g++: error: unrecognized command line option '-rdynamic' make[3]: *** [lib_file_io_la-file_io.lo] Error 1 make[3]: *** [template_F12.lo] Error 1 make[2]: *** [all-recursive] Error 1 make[1]: *** [all-recursive] Error 1 make: *** [all] Error 2 How do I fix this?
