c - Compiling ANTLR 3C for AIX -

i'm not familiar compiling c, if don't give enough information, let me know need me post!

here's summary: need run antlr in target language of c on old ibm aix computer. gave on compiling ibm cc/make utils , got version of gcc (4.2) , gnu make on machine. issue is, while configure script detect correct architecture, not seem respond appropriately.

the specific version of antlr using version 3.2, c target. actual detected target powerpc-ibm-aix-5.3.0.0

here's i've done. first glaring error see added "-m32" flag options. okay, can remove makefile simple enough, in case gcc should default -maix32.

second issue: error giving me path stdio.h , saying "error: duplicate 'unsigned'". okay, configure made "define" statement in auto-generated antlr3config.h file... can comment out, , error goes away.

third issue... i'm stuck.

oh , i'm able compile on other platforms, ubuntu or cygwin (i cannot use them task though). i'm not familiar aix though , have limited experience compiling c programs. perhaps need set things configure script?

thanks!

edit: made progress, updating post keep info together.

i able resolve above error adding --disable-abiflags option when running configure script... option removes -m32 , -m64 gcc flags. allowed configure script work correctly, left assembler little confused when running make. give guidance, added -wa,-a32 flag cflafs in makefile, letting assembler know wanted 32 bit.

there 1 issue remaining.

the problem is, doesn't matter set to. have tried running make not set, , used export set it:

export object_mode=32 

i can type echo $object_mode , indeed print out 32... seems not detect when run make.

i able work around editing "libtool" script add "-x 32" ar options override whatever reading. long-term solution ltmain.sh , re-run configure.

this line in question:

typedef socklen_t antlr3_salent; 

because socklen_t not defined can't typedef it, including socket.h should fix it

#include <sys/socket.h> 

edit: after taking second @ file, socket.h should included if run configure script

#ifdef have_socket_h # include   <socket.h> #else # if have_sys_socket_h #  include  <sys/socket.h> # endif #endif
