past the config.log do the same test fail on default kernel to?

so try building & running the code in question: $ cat test.c main(){exit(strcmp(tgoto("%p1%d", 0, 1), "1") ? 0 : 1);} $ gcc test.c -O2 && ./a.out
fails to compile: test.c: In function 'main': test.c:1: warning: incompatible implicit declaration of built-in function 'exit' /tmp/ccwXMGvk.o: In function `main': test.c:(.text+0x23): undefined reference to `tgoto' collect2: ld returned 1 exit status
link in -lncurses
returns only segmentation fault
does tgoto return NULL ? what if you do: gcc -include term.h test.c -lcurses && ./a.out
Now runs without errors, but not shows any output
simple "implicit decl truncates pointer return type" bug
(In reply to comment #10) > simple "implicit decl truncates pointer return type" bug Well, thanks for the interest and rapid response.
should be all set now in the tree; thanks for the report! Commit message: Fix tgoto test in rlfe example http://sources.gentoo.org/sys-libs/readline/files/readline-6.2-rlfe-tgoto.patch?rev=1.1 http://sources.gentoo.org/sys-libs/readline/readline-6.2_p5.ebuild?rev=1.1
