dis s the prob i am facing wen i am trying to configure fftw 3.1.2

configure: error: no acceptable C compiler found in $PATH

wen i checked the config.log i am getting dis msg.

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by fftw configure 3.1.2, which was
generated by GNU Autoconf 2.59e. Invocation command line was

$ ./configure --enable-float

## --------- ##
## Platform. ##

hostname = localhost.localdomain
uname -m = i686
uname -r = 2.6.18-92.el5

/usr/bin/uname -p = unknown
/bin/uname -X = unknown

/bin/arch = i686
/usr/bin/arch -k = unknown

for god sake some one guide me with dis installation process

Install gcc. Have you already checked whether your distro (from your uname -r output, I'm guessing RHEL?) has a package for FFTW 3? If so, you might as well get that rather than building the source.

The first line of the error message tells you what the problem is: you don't seem to have a C compiler installed. Install GCC using whatever tool your distro supports, then try again.

gcc is already installed....

is der any prob with the version???

Its probably not there in your path. Open a terminal and type 'gcc' (Type it as the same user you are when you run ./configure). Does it say something like 'no input files', or something like 'command not found'? If its the latter, then you need to add gcc's location to your $PATH.

its showing command not found...

i tried to install new version of gcc.tar.bz2 file.

bt its showin no cc found.

can u tel me how to install tat file

The latest version of gcc should be available using the package manager. What version (distro) of Linux are you using?

dis is my distro..

Linux localhost.localdomain 2.6.18-92.el5 #1 SMP Tue Jun 10 18:49:47 EDT 2008 i686 i686 i386 GNU/Linux.

n wen i tried installing new version of gcc its showing

[root@localhost gcc-4.2.4]# ./configure

i am not gettin wat lse i shld install..

As pixellany implied, you need to install gcc via your distro's package manager. Trying to build it from source won't work, because, as you can see, it requires a C compiler. I'd also encourage writing properly.

That is the name of your kernel---but it contains a clue (el5)---it looks like you might be using RedHat Enterprise 5.

Please do not use the "text talk", SMS, or whatever it is called.
