hm, so apparently R was built with gcc-4.2, but reports gcc as the compiler. This seems to be a bug in r-base, then, which will likely also affect source package installation. Which version of r-base-dev/r-base-core do you have installed? Perhaps you need to forcibly re-install r-base-core/r-base-dev? Does anybody else use a fresh gutsy installation? If so, could you check a) the default version of gcc: # gcc --version b) the version R was built with # ldd /usr/lib/R/lib/libR.so | grep "fortran" c) the version R thinks should be used for compilation: # R CMD config CC and post the output? > a second symlink was missing and resulted in a "ld: cannot find -lgfortran" > error. to fix that, a > ln -s /usr/lib/lgfortran.so.2.0.0 /usr/lib/lgfortran.so > would suffice. Same issue, actually, since the 4.1 version of gfortran was used, while the 4.2 version should have been used. > and last but not least i think i ran into a bug in the debian/rules script. > on my system "/usr/bin/R CMD config CC" spits out "gcc -std=gnu99", which > caused an export-call in the rules script to fail with "export: 4: -std: > bad variable name". i simply quoted it and all went fine; here's a patch: o > http://reaktanz.de/stuff/rules.patch Ah, indeed. Probably we should add quotes on the line above and the line below, as well. I'll prepare a fix, shortly. Regards Thomas
