Hi all,
 I'm trying to build a 64bit version of ooRexx 3.1.1 under FC6,
starting from the src.rpm.
 The build fail with:


 /usr/lib/gcc/x86_64-redhat-linux/4.1.1/32/crtbegin.o: In function
`frame_dummy':
 crtstuff.c:(.text+0x40): undefined reference to `_Jv_RegisterClasses'
 collect2: ld returned 1 exit status
 make: *** [rexx] Error 1
 error: Bad exit status from /var/tmp/rpm-tmp.91225 (%build)


RPM build errors:
     Bad exit status from /var/tmp/rpm-tmp.91225 (%build)


Anyone know what this _Jv_RegisterClasses (Java stuff?) is supposed to do?
Is this realy neeeded by ooRexx?
What I've to do to circumvent this problem?


TIA
