[GENERAL] PostgreSQL 8.3.8 on AIX5.3 : compilation failed

[Alexandra Roy]

Hi all, I am trying to compile PostgreSQL 8.3.8 on AIX 5.3 TL9 (64 bits). The ".configure" has been executed with success without any error but the compilation of PostgreSQL with "gmake" fails. Please find below the errors I get : In file included from psqlscan.c:2385: /usr/include/unistd.h:171: error: conflicting types for 'lseek64' /usr/include/unistd.h:169: error: previous declaration of 'lseek64' was here In file included from /usr/include/unistd.h:744,                  from psqlscan.c:2385: /usr/include/sys/lockf.h:64: error: conflicting types for 'lockf64' /usr/include/sys/lockf.h:62: error: previous declaration of 'lockf64' was here In file included from psqlscan.c:2385: /usr/include/unistd.h:807: error: conflicting types for 'ftruncate64' /usr/include/unistd.h:805: error: previous declaration of 'ftruncate64' was here /usr/include/unistd.h:843: error: conflicting types for 'truncate64' /usr/include/unistd.h:841: error: previous declaration of 'truncate64' was here /usr/include/unistd.h:860: error: conflicting types for 'pread64' /usr/include/unistd.h:857: error: previous declaration of 'pread64' was here /usr/include/unistd.h:861: error: conflicting types for 'pwrite64' /usr/include/unistd.h:858: error: previous declaration of 'pwrite64' was here /usr/include/unistd.h:928: error: conflicting types for 'fclear64' /usr/include/unistd.h:925: error: previous declaration of 'fclear64' was here /usr/include/unistd.h:929: error: conflicting types for 'fsync_range64' /usr/include/unistd.h:926: error: previous declaration of 'fsync_range64' was here gmake[3]: *** [psqlscan.o] Error 1 gmake[3]: Leaving directory `/home/PostgreSQL_8.3.8/sources/postgresql-8.3.8/src/bin/psql' gmake[2]: *** [all] Error 2 gmake[2]: Leaving directory `/home/PostgreSQL_8.3.8/sources/postgresql-8.3.8/src/bin' gmake[1]: *** [all] Error 2 gmake[1]: Leaving directory `/home/PostgreSQL_8.3.8/sources/postgresql-8.3.8/src' gmake: *** [all] Error 2 I read on the PostgreSQL.fr's forum that this error is linked to large files in 64 bits system, allowing to read / write files of 2 GB and over. I also read that I can use the "-disable-largefile" while I launched ".configure" but I don't really understand the problem. If PostgreSQL can't use such files, except for trace logs, why the compilation fails on large files ? Thank you for your help. Regards, Alexandra
