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

[Alexandra Roy]

Hi Laurenz, hi all, This is a summary of what I have noticed concerning PostgreSQL 8.3.8 compilation on AIX 5.3 TL9. 1. To do a successful 64-bit build, specify and execute: # export OBJECT_MODE="64" # export CFLAGS="-maix64"               # export LDFLAGS="-maix64 -Wl,-bbigtoc" # ./configure # gmake # gmake install Laurenz, you are right: it is not necessary to specify: # export AR="ar -X64" 2. To do a successful 32-bit build, you must specify: # export OBJECT_MODE="32" and use the "-disable-largefile" option with configure : # ./configure -disable-largefile If I use the "-disable-largefile" option, "configure" indicates at the end: configure: WARNING: option ignored: --enable-largefile And then, the compilation is successful: All of PostgreSQL successfully made. Ready to install. Without the "-disable-largefile" option, the compilation is still failing with this error: 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 Does someone have an idea about this ? Why the "-disable-largefile" option is necessary to do a PostgreSQL 8.3.8 32-build ? Why the "OBJECT_MODE" exported to 32 is not sufficient ? Thank you for your answer. Regards, Alexandra Albe Laurenz a écrit : Alexandra Roy wrote: I have always run "gmake distclean" before relaunching a build. Maybe the32-bit build failed because I have not set and exported the "OBJECT_MODE" environment variable. I will try to build PostgreSQL once again with "export OBJECT_MODE=32". I will look at the 32 bit case again. I continued to test a 64-bit build and finally, I found the procedure to do a 64-bit build of PostgreSQL 8.3.8 on AIX 5.3. As "root" user : You don't have to be root for this. # export OBJECT_MODE=64 # export CFLAGS="-maix64" # export LDFLAGS="-maix64 -Wl,-bbigtoc" # export AR="ar -X64" => this step was missing in my first test This should not be necessary - if you look at the man page of "ar" you will see that the default value of the -X flag is derived from OBJECT_MODE. # ./configure # gmake All of PostgreSQL successfully made. Ready to install. I'm glad that you got it to compile. As non-root user : # gmake check ======================= All 114 tests passed. ======================= As "root" user: # gmake install PostgreSQL installation complete. Yours, Laurenz Albe
