Hi,

I just downloaded Hrv's 1.4.1-dev version and all the support files. Based on the installation instructions, I am suppose to use gmake. But, when I typed gmake, I got "command not found". It looks like gmake is basically make on FreeBSD.

Has anyone tried to install the developement version on either Ubuntu or SuSE? Can I install the development just like the standard version using wmake? Do I need all the utility packages (gdb, cmake)?

Thanks!

Hi Peiying,
gmake I think is the gnu version of make, and on many systems is just a symbolik link to make.
You don't need gdb as long as you don't do debugging. But you need cmake if you are going to compile paraview.

Thanks Dragos!

Now, I am having trouble with gcc.

I downloaded gcc-4.2.2.tgz from powerlab. I got the following errors during configure. I am using OpenSUSE 10.3 64 bit (which has gcc-4.2.1 installed). Any suggestion will be highly appreciated.

Hi,

Can someone tell me which OS is the installation instructions of the development based on?

I am not able to find gcc-4.2.2 for either SuSE or Ubuntu. When I tried to install the OF-1.4.1 development version on SuSE 10.3 64 bit OS, I got some errors (used linux64/gcc-4.2.1 and bash).

Thanks a lot!

You are specifying a path where most likely you don't have access as regular user. Try instead of /usr/tmp/gcc-4.2.2 something else, like /tmp/gcc-4.2.2.

Dear Dragos:

Thanks a lot for the pointer. Your were correct! Now, I am able to compile gcc-4.2.2 using /tmp/gcc-4.2.2 on a 32 bit system. However, I am still having trouble compiling gcc-4.2.2 on a 64 bit OS. I got errors saying incompatible i386 with x86_64. Is there a switch that I can turn on to 64 bit OS, something like WM_64=on?

Thanks again for your reply!

Unfortunately, gcc is not always straight froward to compile. You should have a look at install gcc, especially at prerequisites paragraph.

Dear Dragos:

Thanks for the suggestions. I did look at the gcc installation instructions and the manual. But, I still cannot figure out how to do this.

I sent an email to gcc-help. I might try gcc-4.2.1 later to see if I can make some progress.

Pei, deailed step-by-step instructions to compile gcc and/or even binutils for an OpenFOAM setup are given in the wiki. I have followed these instructions for OF versions 1.3, 1.4 and 1.4.1 and have never faced any problems.

Hi, Srinath,

Thanks for the reply!

By following the steps in the wiki, I am able to compile 1.4.1-dev on 64 bit SuSE 10.2, except dx and paraview. I will try Ubuntu 64 bit later.
