Re: compiling bison-3.0 on AIX 5.3

[Michael Felt]

I tried starting the make on a system with perl 5.8.8 (AIX 6.1) but ran
into a compile error. Because I suspected a configure inconsistency from
the AIX 5.3 system I did a make distclean, and reran the configure command.

On this system I am getting a configure error:
configure:8525: cc -o conftest -O2 -qlanglvl=extc99 -I/opt/include
-D_THREAD_SAFE  conftest.c -ll  >&5
configure:8525: $? = 0
configure:8535: result: -ll
configure:8541: checking whether yytext is a pointer
configure:8558: cc -o conftest -O2 -qlanglvl=extc99 -I/opt/include
-D_THREAD_SAFE  conftest.c -ll  >&5
configure:8558: $? = 1
configure: failed program was:
configure:8566: result: no
configure:8576: error: Flex is required
configure: exit 1

On the AIX 5.3, the same configure command completes successfully.

        --mandir=/usr/share/man  \
                > build/aix/configure.out
cmp: EOF on conftest.ok

Neither system has flex installed - so I am surprised about the message.

Moving on: the syntax error on the AIX 6.1 system (same compiler on both
systems, but I probably do not have all the same libraries/packages
installed).

Something not balanced in this file?
