There are several minor problems using the Sun Studion 12 compiler (on Solaris 10 SPARC)... - in str.c, use of STR causes errors because /usr/include/sys/stropts.h contains: #define STR ('S'<<8) The this just requires replacing "STR" with something safer, such as "XSTR". - things fail horribly because SIZEOF_UNSIGNED_CHAR and friends get defined to 0. AFAICT, this happens because configure erroneously decides that cc suports -pendantic (which it appears to, but which causes linking to fail with the symbol "mcount" undefined). The following patch works around this: Index: configure --- configure.orig 2011-05-03 08:14:28.000000000 +1000 +++ configure 2011-05-04 13:51:53.785750000 +1000 @@ -4210,7 +4210,7 @@ cat confdefs.h - <<_ACEOF >conftest.$ac_ /* end confdefs.h. */ int main() {return 0;} _ACEOF -if ac_fn_c_try_compile "$LINENO"; then : +if ac_fn_c_try_link "$LINENO"; then : { $as_echo "$as_me:${as_lineno-$LINENO}: result: yes" >&5 $as_echo "yes" >&6; } else - the compiler also gives warnings for the '\r' characters in version.h Hope this helps, rlr -- Ross L Richardson <URL:mailto:Ross.Richardson@utas.edu.au> Senior Systems Administrator Phone : +61 (0)3 6226 6233 Information Technology Resources Fax : +61 (0)3 6226 7171 University of Tasmania, AUSTRALIA
