Cross posted from comp-lang-rexx 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 -- Alessandro Brezzi
