I am having a problem similar to something I saw on this list. *** PANIC *** The C compiler can no longer build working executables. *** PANIC *** Please examine the tail of config.log for runtime errors. *** PANIC *** The most likely reason for this problem is that configure *** PANIC *** links with shared libraries, but those libraries cannot be *** PANIC *** found at run time. *** PANIC *** *** PANIC *** On a Linux system, edit /etc/ld.so.conf and re-run ldconfig. *** PANIC *** On other systems, try telling configure where to find the *** PANIC *** shared libraries using the --site-runtime-libraries option *** PANIC *** *** PANIC *** Another way to shoot yourself in the foot is to specify *** PANIC *** --with-FEATURE when FEATURE is not actually installed *** PANIC *** on your system. Don't do that. this is on a linux from scratch system which deffinately has ncurses and does not have termcap. I'm not sure when this broke but everything was building fine a couple of weeks ago. here is what seems to be the relevant portion of config.log: configure:13267: checking for TTY-related features configure:13283: checking for tgetent in -lncurses configure:13299: gcc -o conftest -g -O3 -Wall -Wno-switch -Winline -Wmissing-prototypes -Wshadow -Wsign-compare -I/usr/X11R6/include -L/usr/X11R6/lib conftest.c -lncurses -lXmu -lXt -lXext -lX11 -lSM -lICE -lm -lshell32 -lgdi32 -luser32 -lcomdlg32 -lcomctl32 -lwinspool -lgcc -lc -lgcc /usr/lib/crtn.o 1>&5 /usr/bin/ld: cannot find -lwinspool collect2: ld returned 1 exit status configure: failed program was: #line 13288 "configure" #include "confdefs.h" /* Override any gcc2 internal prototype to avoid an error. */ /* We use char because int might match the return type of a gcc2 builtin and then its argument prototype would still apply. */ char tgetent(); int main() { tgetent() ; return 0; } configure:13588: checking for gpm.h configure:13596: gcc -E -I/usr/X11R6/include conftest.c >/dev/null 2>conftest.out configure:13592: gpm.h: No such file or directory configure: failed program was: #line 13591 "configure" #include "confdefs.h" #include <gpm.h> configure:13685: checking for database support configure:13690: checking for ndbm.h configure:13698: gcc -E -I/usr/X11R6/include conftest.c >/dev/null 2>conftest.out configure:13694: ndbm.h: No such file or directory configure: failed program was: #line 13693 "configure" #include "confdefs.h" #include <ndbm.h> configure:13874: checking for Berkeley db.h configure:13899: gcc -c -g -O3 -Wall -Wno-switch -Winline -Wmissing-prototypes -Wshadow -Wsign-compare -I/usr/X11R6/include conftest.c 1>&5 configure:13892: db/db.h: No such file or directory configure: failed program was: #line 13877 "configure" #include "confdefs.h" #include <stdlib.h> #if !(defined __GLIBC__ && __GLIBC_MINOR__ >= 1) #ifdef HAVE_INTTYPES_H #define __BIT_TYPES_DEFINED__ #include <inttypes.h> typedef uint8_t u_int8_t; typedef uint16_t u_int16_t; typedef uint32_t u_int32_t; #ifdef WE_DONT_NEED_QUADS typedef uint64_t u_int64_t; #endif #endif #endif #include <db/db.h> int main() { ; return 0; } configure:13899: gcc -c -g -O3 -Wall -Wno-switch -Winline -Wmissing-prototypes -Wshadow -Wsign-compare -I/usr/X11R6/include conftest.c 1>&5 configure:13915: checking for Berkeley DB version configure:13956: checking for db_create configure:13982: gcc -o conftest -g -O3 -Wall -Wno-switch -Winline -Wmissing-prototypes -Wshadow -Wsign-compare -I/usr/X11R6/include -L/usr/X11R6/lib conftest.c -lXmu -lXt -lXext -lX11 -lSM -lICE -ltermcap -lcurses -lm -lshell32 -lgdi32 -luser32 -lcomdlg32 -lcomctl32 -lwinspool -lgcc -lc -lgcc /usr/lib/crtn.o 1>&5 /usr/bin/ld: cannot find -ltermcap collect2: ld returned 1 exit status configure: failed program was: #line 13959 "configure" #include "confdefs.h" /* System header to define __stub macros and hopefully few prototypes, which can conflict with char db_create(); below. */ #include <assert.h> /* Override any gcc2 internal prototype to avoid an error. */ /* We use char because int might match the return type of a gcc2 builtin and then its argument prototype would still apply. */ char db_create(); int main() { /* The GNU C library defines this for functions which it implements to always fail with ENOSYS.
