我尝试在RHEL 6上安装gcc 4.7.2。我从here下载了tar.gz存档，并执行了以下步骤。
tar zxvf gcc-4.7.2.tar.gz
cd gcc-4.7.2
./configure --prefix=/usr/local/gcc-4.7.2/ --mandir=/usr/share/man --infodir=/usr/share/info --with-bugurl=http://bugzilla.redhat.com/bugzilla --enable-bootstrap --enable-shared --enable-threads=posix --enable-checking=release --with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --enable-gnu-unique-object --enable-languages=c,c++,objc,obj-c++,java,fortran,ada --enable-java-awt=gtk --disable-dssi --with-java-home=/usr/lib/jvm/java-1.5.0-gcj-1.5.0.0/jre --enable-libgcj-multifile --enable-java-maintainer-mode --with-ecj-jar=/usr/share/java/eclipse-ecj.jar --disable-libjava-multilib --with-tune=generic --with-gmp=/usr/local/gimp-4.3.2/ --with-mpfr=/usr/local/mpfr-2.4.2/ --with-mpc=/usr/local/mpc-0.8.1/ --with-ppl=/usr/local/ppl-0.11 --with-cloog=/usr/local/cloog-ppl-0.15/
make
每当我执行 make 时，都会抛出以下错误：
cp ../.././gcc/../fixincludes/README-fixinc include-fixed/README

如何解决此错误？
答案 0 :(得分：0)
我已经解决了我的问题。我已经将gmp，mpc，mpfr，ppl库的路径导出到环境变量LD_LIBRARY_PATH。
