Many functions and headers are mentioned in both BuildSystem and PETSc, thus being tested more than once. Removing this redundancy speeds up my configure from 125 seconds to 110 seconds. --- The full list of redundant configure tests is shown below. HAVE_LIBLAPACK is anomalous because it is actually testing for different functions. $ grep 'Defined .HAVE_' mpich-basic/conf/configure.log | sed 's,^ \+,,' | sort | uniq -cd 2 Defined "HAVE_ACCESS" to "1" 2 Defined "HAVE_BZERO" to "1" 2 Defined "HAVE_CLOCK" to "1" 2 Defined "HAVE_DLCLOSE" to "1" 2 Defined "HAVE_DLERROR" to "1" 2 Defined "HAVE_DLOPEN" to "1" 2 Defined "HAVE_DLSYM" to "1" 2 Defined "HAVE_DRAND48" to "1" 2 Defined "HAVE_ENDIAN_H" to "1" 2 Defined "HAVE_FCNTL_H" to "1" 2 Defined "HAVE_FENV_H" to "1" 4 Defined "HAVE_FLOAT_H" to "1" 2 Defined "HAVE_FORK" to "1" 2 Defined "HAVE_GETCWD" to "1" 2 Defined "HAVE_GETDOMAINNAME" to "1" 2 Defined "HAVE_GETHOSTBYNAME" to "1" 2 Defined "HAVE_GETHOSTNAME" to "1" 2 Defined "HAVE_GET_NPROCS" to "1" 4 Defined "HAVE_GETPAGESIZE" to "1" 2 Defined "HAVE_GETPWUID" to "1" 2 Defined "HAVE_GETRUSAGE" to "1" 2 Defined "HAVE_GETTIMEOFDAY" to "1" 2 Defined "HAVE_GETWD" to "1" 2 Defined "HAVE_LIBBLAS" to "1" 3 Defined "HAVE_LIBDL" to "1" 27 Defined "HAVE_LIBLAPACK" to "1" 5 Defined "HAVE_LIBM" to "1" 2 Defined "HAVE_LIBZ" to "1" 2 Defined "HAVE_LIMITS_H" to "1" 2 Defined "HAVE_LSEEK" to "1" 2 Defined "HAVE_MALLOC_H" to "1" 2 Defined "HAVE_MEMALIGN" to "1" 2 Defined "HAVE_MEMMOVE" to "1" 2 Defined "HAVE_MEMORY_H" to "1" 2 Defined "HAVE_MKSTEMP" to "1" 2 Defined "HAVE_MPI_FINALIZED" to "1" 2 Defined "HAVE_NETDB_H" to "1" 2 Defined "HAVE_NETINET_IN_H" to "1" 2 Defined "HAVE_POPEN" to "1" 2 Defined "HAVE_PTHREAD_H" to "1" 2 Defined "HAVE_PWD_H" to "1" 2 Defined "HAVE_RAND" to "1" 2 Defined "HAVE_READLINK" to "1" 2 Defined "HAVE_REALPATH" to "1" 2 Defined "HAVE_SCHED_H" to "1" 2 Defined "HAVE_SEARCH_H" to "1" 2 Defined "HAVE_SETJMP_H" to "1" 2 Defined "HAVE_SIGACTION" to "1" 2 Defined "HAVE_SIGNAL" to "1" 2 Defined "HAVE_SIGSET" to "1" 2 Defined "HAVE_SLEEP" to "1" 2 Defined "HAVE_SNPRINTF" to "1" 2 Defined "HAVE_SOCKET" to "1" 2 Defined "HAVE_STDINT_H" to "1" 2 Defined "HAVE_STDLIB_H" to "1" 2 Defined "HAVE_STRCASECMP" to "1" 2 Defined "HAVE_STRING_H" to "1" 2 Defined "HAVE_STRINGS_H" to "1" 2 Defined "HAVE_SYS_PARAM_H" to "1" 2 Defined "HAVE_SYS_PROCFS_H" to "1" 2 Defined "HAVE_SYS_RESOURCE_H" to "1" 2 Defined "HAVE_SYS_SOCKET_H" to "1" 3 Defined "HAVE_SYS_SYSINFO_H" to "1" 2 Defined "HAVE_SYS_TIMES_H" to "1" 2 Defined "HAVE_SYS_TYPES_H" to "1" 2 Defined "HAVE_SYS_UTSNAME_H" to "1" 3 Defined "HAVE_SYS_WAIT_H" to "1" 3 Defined "HAVE_TIME_H" to "1" 2 Defined "HAVE_TIMES" to "1" 2 Defined "HAVE_TIME" to "1" 2 Defined "HAVE_UNAME" to "1" 2 Defined "HAVE_UNISTD_H" to "1" 2 Defined "HAVE_USLEEP" to "1" After this patch, we have a few "redundant" tests left. 2 Defined "HAVE_LIBBLAS" to "1" 3 Defined "HAVE_LIBDL" to "1" 27 Defined "HAVE_LIBLAPACK" to "1" 5 Defined "HAVE_LIBM" to "1" 2 Defined "HAVE_LIBZ" to "1" 2 Defined "HAVE_MPI_FINALIZED" to "1" 2 Defined "HAVE_SYS_SYSINFO_H" to "1" 2 Defined "HAVE_SYS_WAIT_H" to "1" 2 Defined "HAVE_TIME_H" to "1" I have not de-duplicated libraries.py yet because it passes in more structured arguments.
