I am trying to compile, on my x86_64 RHEL machine (CentOS 6.4), the GCC compiler with Intel CilkPlus (v4.9) module for compiling applications targeting parallel multicore platforms.
I am following GNU GCC Doc for installation which is very very similar for the GCC with CilkPlus extension. I was particularly focused on providing good attention to the Prerequisites and Configuration sections of the before-mentioned doc.
1) Download
I did download everything I needed using this snapshot as specified in the Instructions page. Download was successful and un-tar as well. I did rename the folder as cilkplus-gcc and put it under my $HOME directory.
I also created another directory: $HOME/b-gcc from where I intend to run the configure command and then make commands. This will prevent from installing into the same directory (something undesirable for this procedure which encourages building everything on a different directory).
2) Initial configuration
As specified in the documentation, I moved into the $HOME/cilkplus-gcc/contrib directory in order to build the three most important libraries needed by the installation process (that is: compiling GCC):
- GMP: located into the
$HOME/cilkplus-gcc/contrib/gmp-4.3.2directory. - MPFR: located into the
$HOME/cilkplus-gcc/contrib/mpfr-2.4.2directory. - MPC: located into the
$HOME/cilkplus-gcc/contrib/mpc-0.8.1directory.
I build them in the order of appearance as MPFR depends on GMP and MPC depends on both GMP and MPFR. I wanted to place ll needed files into the $HOME/cilkplus-gcc directory so I instructed the installers of these libraries to place everything into the $HOME/cilkplus-gcc/contrib/tmp directory. So:
sudo $HOME/cilkplus-gcc/contrib/gmp-4.3.2/configure --enable-shared --enable-static --prefix=$HOME/cilkplus-gcc/contrib/tmp
sudo $HOME/cilkplus-gcc/contrib/mpfr-2.4.2/configure --enable-shared --enable-static --prefix=$HOME/cilkplus-gcc/contrib/tmp --with-gmp=$HOME/cilkplus-gcc/contrib/tmp
sudo $HOME/cilkplus-gcc/contrib/mpc-0.8.1/configure --enable-shared --enable-static --prefix=$HOME/cilkplus-gcc/contrib/tmp --with-gmp=$HOME/cilkplus-gcc/contrib/tmp --with-mpfr=$HOME/cilkplus-gcc/contrib/tmp
As direct result, my $HOME/cilkplus-gcc/contrib/tmp directory is filled with directories lib, include, share and bin with those three libs inside.
3) Installation
Time to get busy compiling everything. I move into the $HOME/b-gcc directory and from there I issue the following command:
sudo $HOME/cilkplus-gcc/configure --prefix=$HOME/cilkplus-install --enable-languages="c,c++" --with-gmp=$HOME/cilkplus-gcc/contrib/tmp/ --with-mpfr=$HOME/cilkplus-gcc/contrib/tmp/ --with-mpc=$HOME/cilkplus-gcc/contrib/tmp/
The configuration goes smoothly and creates make stuff into my current folder ($HOME/b-gcc). Time to make and I issue: sudo make.
Two minutes and I get this error

But I check my /usr/local/lib folder and I can clearly see that libiconv.so.2 is there! So I understand the installation procedure (that is GCC compiling itself) cannot find the library (clearly referenced as I can see the -liconv flag). So I delete everything in $HOME/b-gcc and issue a modified configure command:
sudo $HOME/cilkplus-gcc/configure --prefix=$HOME/cilkplus-install --enable-languages="c,c++" --with-gmp=$HOME/cilkplus-gcc/contrib/tmp/ --with-mpfr=$HOME/cilkplus-gcc/contrib/tmp/ --with-mpc=$HOME/cilkplus-gcc/contrib/tmp/ --with-stage1-ldflags=-L/usr/local/lib
As I issue sudo make again, the previous error is not encountered anymore and time passes. After 5/6 minutes I get this error:

Well, quite a strange stuff... So I checked $HOME/b-gcc/x86_64-unknown-linux-gnu/libgcc/config.log (gonna show the relevant excerpt):
-isystem /home/andry/cilkplus-install/x86_64-unknown-linux-gnu/sys-include

Saying that the error is basically the following:
/home/andry/b-gcc/./gcc/cc1: error while loading shared libraries: libmpc.so.2: cannot open shared object file: No such file or directory
But didn't I already told it (during configure) to go search for libmpc.so.2 into $HOME/cilkplus-gcc/contrib/tmp???
How can I get things done?
How can I get through this? Thankyou
