%general-entities; ]> Bzip2 N32 We need to remove the tests since they won't work on a multi-architecture build, and tell change the default lib path to lib32: sed -i -e 's@^\(all:.*\) test@\1@g' \ -e 's@/lib\(/\| \|$\)@/lib32\1@g' Makefile make -f Makefile-libbz2_so CC="gcc ${BUILDN32}" CXX="g++ ${BUILDN32}" make clean make CC="gcc ${BUILDN32}" CXX="g++ ${BUILDN32}" Now we remove the 32 bit versions of the programs so we can install the n32 bit versions. cp bzip2-shared /bin/bzip2 cp -a libbz2.so* /lib32 ln -s ../../lib32/libbz2.so.1.0 /usr/lib32/libbz2.so rm /usr/bin/{bunzip2,bzcat,bzip2} ln -s bzip2 /bin/bunzip2 ln -s bzip2 /bin/bzcat
