Thread: Compiling tsearch2 on AIX
I am trying to compile PostgreSQL 8.0.3/tsearch2 contrib module on AIX 5.2 ML 3 gcc version 3.3.2 GNU Make 3.80 bash-2.05b# gmake gcc -O2 -Wall -Wmissing-prototypes -Wpointer-arith -Wendif-labels -fno-strict-aliasing -I./snowball -I./ispell -I./wordparser -I. -I../../src/include -c -o dict_ex.o dict_ex.c In file included from ../../src/include/c.h:64, from ../../src/include/postgres.h:48, fromdict_ex.c:9: /opt/freeware/lib/gcc-lib/powerpc-ibm-aix5.2.0.0/3.3.2/include/stdio.h:484: error: conflicting types for `fgetpos64' /opt/freeware/lib/gcc-lib/powerpc-ibm-aix5.2.0.0/3.3.2/include/stdio.h:310: error: previous declaration of `fgetpos64' /opt/freeware/lib/gcc-lib/powerpc-ibm-aix5.2.0.0/3.3.2/include/stdio.h:487: error: conflicting types for `fseeko64' /opt/freeware/lib/gcc-lib/powerpc-ibm-aix5.2.0.0/3.3.2/include/stdio.h:430: error: previous declaration of `fseeko64' /opt/freeware/lib/gcc-lib/powerpc-ibm-aix5.2.0.0/3.3.2/include/stdio.h:488: error: conflicting types for `fsetpos64' /opt/freeware/lib/gcc-lib/powerpc-ibm-aix5.2.0.0/3.3.2/include/stdio.h:312: error: previous declaration of `fsetpos64' /opt/freeware/lib/gcc-lib/powerpc-ibm-aix5.2.0.0/3.3.2/include/stdio.h:489: error: conflicting types for `ftello64' /opt/freeware/lib/gcc-lib/powerpc-ibm-aix5.2.0.0/3.3.2/include/stdio.h:431: error: previous declaration of `ftello64' gmake: *** [dict_ex.o] Error 1 Can someone please let me know why this is happening?

We discovered long ago that when pg_config.h defines _FILE_OFFSET_BITS or _LARGEFILE_SOURCE, it's critical that the compiler see that *before* it includes stdio.h.

Thanks for the reply Tom! I managed to get the cvs version and I made more progress compiling tsearch2 Here is where it errors out. touch libtsearch2.a ../../src/backend/port/aix/mkldexport.sh libtsearch2.a > libtsearch2.exp gcc -O2 -Wall -Wmissing-prototypes -Wpointer-arith -Wendif-labels -fno-strict-aliasing -Wl,-bnoentry -Wl,-H512 -Wl,-bM:SRE -o libtsearch2.so libtsearch2.a -L../../src/port -L../../src/port -lm -Wl,-bI:../../src/backend/postgres.imp -Wl,-bE:libtsearch2.exp ld: 0711-317 ERROR: Undefined symbol: .get_share_path ld: 0711-317 ERROR: Undefined symbol: .pg_strncasecmp ld: 0711-317 ERROR: Undefined symbol: .pg_strcasecmp ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more information. collect2: ld returned 8 exit status gmake: *** [libtsearch2.so] Error 1 Any ideas?

Tom: Got it working! I had to modify this line in the tsearch2 Makefile from SHLIB_LINK := -lm to SHLIB_LINK := -lm -lpgport it works like a charm! thanks for your help!

Hmm, that's annoying. I was about to commit this change but it actively
fails on my machine:
/usr/ccs/bin/ld: DP relative code in file ../../src/port/libpgport.a(exec.o) - shared library must be position
independent. Use +z or +Z to recompile.
make: *** [libtsearch2.sl.0] Error 1
So we need to think harder. I wonder why the libpgport symbols aren't
getting picked up from the backend itself on your machine?
