I am trying to build a bash builtin on cygwin. Here's the error message I get via automake/make:
$ make gcc -g -O2 -o set0.exe -shared set0-set0.o set0-set0.o: In function `set0_builtin': /tmp/bashdb/builtin/set0.c:46: undefined reference to `_builtin_error' /tmp/bashdb/builtin/set0.c:47: undefined reference to `_builtin_usage' /tmp/bashdb/builtin/set0.c:51: undefined reference to `_dollar_vars' /tmp/bashdb/builtin/set0.c:52: undefined reference to `_xmalloc' /tmp/bashdb/builtin/set0.c:52: undefined reference to `_dollar_vars' /tmp/bashdb/builtin/set0.c:42: undefined reference to `_builtin_error' /tmp/bashdb/builtin/set0.c:43: undefined reference to `_builtin_usage' collect2: ld returned 1 exit status make: *** [set0.exe] Error 1 Perhaps I need to tell cygwin that these symbols are supposed to be undefined since they are part of bash? Thanks for the help or suggestions, rocky
