?I am trying to build a bash "builtin" (a dynamically loadable bash
module) on cygwin. Here's the error message I get via automake/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:43: undefined reference to `_builtin_usage'
collect2: ld returned 1 exit status
make: *** [set0.exe] Error 1
The complete Makefile.am and code is listed at
Perhaps I need to tell cygwin that these symbols are supposed to be
undefined since they are part of bash?
I've tried looking at gcc documentation for linker options but it's
all a mystery to me.
Thanks in advance for help, suggestions or links to documentation.
