RE: glibc-2.7 and gcc-4.2.2 install on redhat 3 u 9 - x86_64

[Lamont, Brian-p3354c]

Lajos,
i changed to <iostream>, and it gave the same error.

# gcc hello.c
hello.c:1:22: error: iostream.h: No such file or directory
hello.c:2: error: expected â=â, â,â, â;â, âasmâ or â__attribute__â before 
ânames paceâ
hello.c: In function âmainâ:
hello.c:3: error: âcoutâ undeclared (first use in this function)
hello.c:3: error: (Each undeclared identifier is reported only once
hello.c:3: error: for each function it appears in.)


i then used "g++" instead, and it gave a different error.

g++ hello.c
hello.c:1:20: error: iostream: No such file or directory
hello.c: In function âint main()â:
hello.c:3: error: âcoutâ was not declared in this scope


this happens using g++ with both iostream and iostream.h.  iostream is located 
below.

# find / -name iostream.h
/usr/include/c++/3.2.3/backward/iostream.h
/usr/include/g++-3/iostream.h
/lib64/ssa/gcc-lib/x86_64-redhat-linux-gnu/3.5-tree-ssa/include/c++/backward/iostream.h
find: . changed during execution of find



which g++
/usr/bin/g++

 which gcc
/usr/bin/gcc


if the problem is not finding iostream, how do i get the program to know where 
it is?   And do i need glibc installed?   I'm also reading blurbs that glibc 
cannot be installed on a live system.

                        ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Use <iostream>.
