OK, I had built mine with Gcc 4.6, so I apparently also had even more issues than your build has.

I've switched to Gcc 4.4.6 as well on my Ubuntu 11.10. For that, I've modified OpenFOAM's "etc/bash" to have these settings:

Code:

export WM_CC='gcc-4.4'

export WM_CXX='g++-4.4'

Additionally, I messed up on the previous diff. The proper lines for "wmake/rules/linux64Gcc/c++" and "wmake/rules/linuxGcc/c++" are:

Code:

LINKLIBSO   = $(CC) $(c++FLAGS) -shared -Xlinker --add-needed -Xlinker --no-as-needed

LINKEXE     = $(CC) $(c++FLAGS) -Xlinker --add-needed -Xlinker --no-as-needed

It's going to take a while to rebuild 1.7.x from scratch. I'll make another post when I have news, although I'm not sure if it will be in the next hour...

:mad: If I hadn't inspected the "make.log" sooner, it would have been a wasted hour... here's the necessary patch, which without the settings from bashrc won't propagate to wmake (swap "linux64Gcc" to "linuxGcc" for 32bit):

wclean all

Yuri, in case you don't know, you can build with multi-core by running this command before Allwmake:

Code:

export WM_NCOMPPROCS=4

This is for 4 cores, i.e. 4 parallel threads for building OpenFOAM.

Hi Yuri,

OK, I've finished confirming this. With the info from the last 2 posts, you should succeed in building everything.

Keep in mind:

I've tested things with 64bit, but left instructions on what's different for the 32bit build.
And later on don't forget to run Allwclean first in the "fireFoam.1.7.x_0.4" folder.

Best regards,
Bruno

That is a great news, Bruno! I'm trying to compiling the OF also, utilizing yours implementations, I rope that this time it will work.

I will post the results here soon.

Hi Bruno,

I really want to thank you so much for your support! The OF17x compilation worked. In addition to your corrections, I changed the variable WM_ARCH_OPTION, which was set by default 64, but my Ubuntu is 32 bits. Could be this one of the reasons for the previous failures?

After this, I finally compiled successfully the fireFoam.1.7.x_0.4! So, the big deal was really the OF17x compilation.

Thanks again for your help!

Hi,

I am getting error while compiling the OF 1.7.x.

I have followed till the previous step but unable to understand comment #22 .

Which files i have to swap as i am using ubuntu 32bit
If possible can you change in the git repository

It will be of great help ...

Thank You

Regards,
Trinath Rao

It's simple ;): in comment #22, whenever you find the text "linux64Gcc" in the instructions, change it to "linuxGcc".

If I'm not mistaken, this is what it should be like for "linuxGcc":
