Hi everyone, I was trying to reproduce building a 32 bit version of R on a 64 bit Ubuntu 11.04 machine (which worked before) with the latest version of R in SVN but am getting this error:
make[3]: Leaving directory `/home/vinh/Downloads/R/trunk/src/modules/lapack' /usr/bin/ld: skipping incompatible /usr/lib/x86_64-linux-gnu/libSM.so when searching for -lSM /usr/bin/ld: skipping incompatible /usr/lib/x86_64-linux-gnu/libSM.a when searching for -lSM /usr/bin/ld: skipping incompatible /usr/lib/x86_64-linux-gnu/libICE.so when searching for -lICE /usr/bin/ld: skipping incompatible /usr/lib/x86_64-linux-gnu/libICE.a when searching for -lICE /usr/bin/ld: skipping incompatible /usr/lib/x86_64-linux-gnu/libpangocairo-1.0.so when searching for -lpangocairo-1.0 ... It should be looking in /usr/lib32, not /usr/lib. I did the following to arrive at these messages: sudo apt-get install ia32-libs lib32readline6-dev lib32ncurses5-dev lib32icu-dev gcc-multilib gfortran-multilib ## ubuntu does not have ia32-libs-dev ./configure r_arch=i386 CC='gcc -std=gnu99 -m32' CXX='g++ -m32' FC='gfortran -m32' F77='gfortran -m32' make -j24 Any suggestions on how to fix this?
