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. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of FÖLDY Lajos Sent: Monday, April 14, 2008 11:31 PM To: help-gplusplus@gnu.org Subject: Re: glibc-2.7 and gcc-4.2.2 install on redhat 3 u 9 - x86_64 On Mon, 14 Apr 2008, Lamont, Brian-p3354c wrote: > Hello, > I'm trying to install gcc-4.2.2, and It appeared to install ok, but cannot > compile the hello program below.
