Hello Jens, >>Hmm, I'll see if I can add a check in configure for whether or not lex >>requires -o to specify an output file. For now, just use --disable-lex. >OK, i continue to just use: --disable-yes. >If you add a check in configure later, i'll try a ./configure to confirm you that's fine in AIX. I build against fio-63bda37 (configure: if lex requires/fails with -o for output) With configure, i have this: ____ MTD no 0: Warning: 1285-300 The o flag is not valid. 0: Error: 1285-331 Cannot read input file lex.yy.c lex/yacc for arithmetic yes ____ and the make fail with: ---- YACC y.tab.c yacc: 1285-770 The -o flag is now the default in yacc. yacc: 1285-725 Reached end of file before %% Line 1 Makefile:313: recipe for target 'y.tab.c' failed gmake: *** [y.tab.c] Error 1 ---- Below the full output: # ./configure Operating system AIX CPU ppc Big endian yes Compiler gcc Cross compile no Static build no Wordsize 32 zlib yes Linux AIO support no POSIX AIO support yes POSIX AIO support needs -lrt no POSIX AIO fsync yes Solaris AIO support no __sync_fetch_and_add no libverbs no rdmacm yes Linux fallocate no POSIX fadvise yes POSIX fallocate yes sched_setaffinity(3 arg) no sched_setaffinity(2 arg) no clock_gettime yes CLOCK_MONOTONIC yes CLOCK_MONOTONIC_RAW no CLOCK_MONOTONIC_PRECISE no gettimeofday yes fdatasync yes sync_file_range no EXT4 move extent no Linux splice(2) no GUASI no Fusion-io atomic engine no libnuma no strsep yes strcasestr no strlcat no getopt_long_only() no inet_aton yes socklen_t yes __thread yes RUSAGE_THREAD yes SCHED_IDLE no TCP_NODELAY yes Net engine window_size yes TCP_MAXSEG yes RLIMIT_MEMLOCK no pwritev/preadv yes IPv6 helpers yes Rados Block Device engine no setvbuf yes Gluster API engine no s390_z196_facilities no HDFS engine no MTD no 0: Warning: 1285-300 The o flag is not valid. 0: Error: 1285-331 Cannot read input file lex.yy.c lex/yacc for arithmetic yes getmntent yes getmntinfo no Static Assert yes bool yes # gmake CC=gcc FIO_VERSION = fio-2.3 CC crc/crc64.o CC crc/md5.o CC crc/fnv.o CC crc/sha256.o CC crc/test.o CC crc/xxhash.o CC crc/crc32c-intel.o CC crc/murmur3.o CC crc/crc32.o CC crc/crc32c.o CC crc/sha1.o CC crc/crc7.o CC crc/sha512.o CC crc/crc16.o CC lib/gauss.o CC lib/prio_tree.o CC lib/axmap.o CC lib/flist_sort.o CC lib/hweight.o CC lib/zipf.o CC lib/getrusage.o CC lib/output_buffer.o CC lib/memalign.o CC lib/lfsr.o CC lib/bloom.o CC lib/strntol.o CC lib/num2str.o CC lib/mountcheck.o CC lib/pattern.o CC lib/ieee754.o CC lib/rbtree.o CC lib/rand.o CC gettime.o CC ioengines.o CC init.o CC stat.o CC log.o CC time.o CC filesetup.o CC eta.o CC verify.o CC memory.o CC io_u.o LEX lex.yy.c YACC y.tab.c yacc: 1285-770 The -o flag is now the default in yacc. yacc: 1285-725 Reached end of file before %% Line 1 Makefile:313: recipe for target 'y.tab.c' failed gmake: *** [y.tab.c] Error 1 # Regards, Thierry-- To unsubscribe from this list: send the line "unsubscribe fio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
