sudo failds to build, "undefined reference to `isblank'"
Last modified: 2007-04-24 14:52:27 MDT
My compile of sudo on Solaris 9 seems to fail, error is: sudo_edit.o: In function `sudo_edit': sudo_edit.c:(.text+0x23c): undefined reference to `isblank' sudo_edit.c:(.text+0x250): undefined reference to `isblank' defaults.o: In function `set_default': defaults.c:(.text+0x6e8): undefined reference to `isblank' defaults.c:(.text+0x720): undefined reference to `isblank' collect2: ld returned 1 exit status make: *** [sudo] Error 1 My C compiler is gcc 4.1.1, built on this box last week. I googled for 'sudo isblank' and found references to a couple of other people with a similar problem. I couldn't see any obvious fix. I'm happy to try stuff out to get a proper solution to this. -- Steve.

I encountered this yesterday and did a fair bit of debugging. solaris doesn't have isblank. Neither does gcc. However, the test the sudo's configure uses is: #include <ctype.h> int main () { (void)isblank(1); ; return 0; } It looks like gcc optimizes this away, so the test passes erroneously. Autoconf 2.59 has a better test: int main() { extern char isblank(); char (*f)() = isblank; return isblank != f; } I don't know if sudo just has an old autoconf, or a bad test, but this seems to pretty clearly be the problem. I fixed my build by patching configure to just never set HAVE_ISBLANK.
The configure script in cvs has been rebuilt with a newer autoconf.
