I use these compilations options for my 2 PCs under Redhat 7.2 & Mandrake 8.1 :

Make 3.79.1
Gcc 3.0.3
Opensll 0.9.6c


For my RedHat 7.2 with i586 & GLIBC 2.2.5 & Bison 1.31
CFLAGS=$'-O3 -fomit-frame-pointer -fno-strict-aliasing -fno-common -pipe -mpreferred-stack-boundary=2 -march=i586'

For my Mandrake 8.1 with i686 & GLIBC 2.2.4 & Bison 1.33
CFLAGS=$'-O3 -fomit-frame-pointer -fno-strict-aliasing -fno-common -pipe -mpreferred-stack-boundary=2 -march=i686'

To compile php i use :

./configure --prefix=/php
make
and it begins to compiling correcty to finish :


./.libs/libphp4.a(zend_ini_scanner.o)(.bss+0x10014): multiple definition of `yytext'
./.libs/libphp4.a(zend_language_scanner.o)(.bss+0x8): first defined here
collect2: ld returned 1 exit status
make[1]: *** [php] Error 1
make[1]: Leaving directory `/home/dmansart/php-4.1.1'
make: *** [all-recursive] Error 1


I don't understand why but if I remove from my compilations options this :
-fno-common

it works perfectly !!!
