I'm trying to compile nmap on a FC-5 system, latest kernel, gcc version:
Using built-in specs.
Target: i386-redhat-linux
Configured with: ../configure --prefix=/usr --mandir=/usr/share/man
--infodir=/usr/share/info --enable-shared --enable-threads=posix
--enable-checking=release --with-system-zlib --enable-__cxa_atexit
--disable-libunwind-exceptions --enable-libgcj-multifile
--enable-languages=c,c++,objc,obj-c++,java,fortran,ada
--enable-java-awt=gtk --disable-dssi
--with-java-home=/usr/lib/jvm/java-1.4.2-gcj-1.4.2.0/jre
--with-cpu=generic --host=i386-redhat-linux
Thread model: posix
gcc version 4.1.1 20060525 (Red Hat 4.1.1-1)
The nmap configure script fails, saying that I don't have a c++
compiler. If I use ./configure CXX=/usr/bin/gcc it'll get part of the
way through then choke at:
checking whether we are using the GNU C++ compiler... no
checking whether /usr/bin/gcc accepts -g... no
checking dependency style of /usr/bin/gcc... none
checking how to run the C++ preprocessor... /lib/cpp
configure: error: C++ preprocessor "/lib/cpp" fails sanity check
What am I missing? Thanks much.
