I want to build luatex-beta-0.30 on my Ubuntu 8.04. I run ./build.sh or ./build.sh.linux, it return error. ~/luatex-beta-0.30.0$ ./build.sh Your make is a GNU-make; I will use that ignore warnings and errors about the main texmf tree checking whether make sets $(MAKE)... yes checking for gcc... gcc checking for C compiler default output file name... configure: error: C compiler cannot create executables See `config.log' for more details. My gcc version is: :~/luatex-beta-0.30.0$ gcc -v Using built-in specs. Target: i486-linux-gnu Configured with: ../src/configure -v --enable-languages=c,c++,fortran,objc,obj-c++,treelang --prefix=/usr --enable-shared --with-system-zlib --libexecdir=/usr/lib --without-included-gettext --enable-threads=posix --enable-nls --with-gxx-include-dir=/usr/include/c++/4.2 --program-suffix=-4.2 --enable-clocale=gnu --enable-libstdcxx-debug --enable-objc-gc --enable-mpfr --enable-targets=all --enable-checking=release --build=i486-linux-gnu --host=i486-linux-gnu --target=i486-linux-gnu Thread model: posix gcc version 4.2.3 (Ubuntu 4.2.3-2ubuntu7) Could anyone tell me what's the problem? Thanks!
