Problem with "make" command in Linux
Hi all,
I downloaded an external program and extracted all the files to a folder. they have a make file which I have to run. But when I run make file I get an error
Code:
g++  -O2 -c pgm.cpp 
make: g++: Command not found
make: *** [pgm.o] Error 127

When I checked the list of GCC I get this
Code:
binf-01 (kmohanas) 1002 $yum list gcc*

Could anyone please tell me what the error is and what exactly I have to do. I have no clue about this. Any help is very much appreciated.

Thanks

You are missing g++, see if you have gcc-c++ package installed and if not, install that.

Hi Mr.Bean,
When I tried installing it, I get a message like this
Code:
sbinf-01 (kmohanas) 1014 $su root yum install gcc-c++
Password: 
yum: line 1: fg: no job control
yum: line 2: syntax error near unexpected token `ImageMagick'
yum: line 2: `%%Creator: (ImageMagick)'

rather than doing everything with just 1 command, try to su root first, enter password and then yum install gcc-c++

Hi Mr.Bean ,
Thank you so much. I could install the g++ library now. However when I run make file of the program I downloaded, I get something like this,
Code:
sbinf-01 (kmohanas) 211 $make
g++  -O2 -c pgm.cpp 
In file included from pgm.cpp:12:
pgm.h:16:49: error: iostream.h: No such file or directory

make: *** [pgm.o] Error 1

Could please tell me what is happening exactly

You'll need libstdc++-devel very likely

Hi Mr.Bean,
I think it is already installed as when I checked it said,
Code:
sbinf-01 (kmohanas) 207 $yum install libstdc++-devel*
Loaded plugins: fastestmirror, refresh-packagekit, security
Loading mirror speeds from cached hostfile
 * base: mirror.as24220.net
 * extras: mirror.internode.on.net
 * updates: mirror.as24220.net
Setting up Install Process
Package libstdc++-devel-4.4.7-3.el6.x86_64 already installed and latest version
Nothing to do

What do you rekon the problem might be?
