error: 'size_t' has not been declared: compilation, 1.6-ext, Fedora 15 x86_64
 

Hi everyone,

I'm seeing an unusual error during the compilation of OpenFOAM-1.6-ext (Thirdparty) on Fedora 15 x86_64: during Allmake.stage3 (mesquite compilation), the type size_t (glibc, stl) does not seem to be declared:

I've checked all the -dev packages for C++ and they all seem to be there, if anyone has any idea about this, it would save me some digging time!

Thanks in advance!

Well, I've figured it out. It seems that there have been some changes in gcc-4.6.1 involving stl headers.

The answer is to compile 1.6-ext with an older gcc compiler.

So, this is a micro how-to for compiling OpenFOAM-1.6-ext in /opt/OpenFOAM on Fedora 16, x86_64:

1) in $WM_PROJECT_DIR/etc/settings.sh change the variable 'compilerInstall':

compilerInstall=OpenFOAM

2) set the compiler version to Gcc44 at the top of settings.sh

export WM_COMPILER=Gcc44

3) set the compiler version back to Gcc inside the switch-case at the bottom of settings.sh (line 182-ish):

the line that should be added is export WM_COMPILER='Gcc', because of the rules for wmake are set with the 'Gcc' not 'Gcc44' or 'Gcc45' string suffix, so if the WM_COMPILER is left to be 'Gcc*' (* is determined in Thirdparty, explained below).

4) source the $WM_PROJECT_DIR/etc/settings.sh (you'll get errors on missing directories in Thirdparty, e.g. gcc-4.4.5 if you have set WM_COMPILER='Gcc44' at the top of settings.sh : do not worry about this it will be set by Thirdparty installation when the directories are created at the end of the compilation process).

5) Go to the ThirdParty directory.

6) Uncomment the appropriate lines in AllMake.stage1 for gcc-4.4.5

7) ./AllMake 2>&1 | tee log.errors

Checkout the log.errors for errors in the Thirdparty compilation and if there were some, post to this thread. :)

If not, compile on, src, apps and utilities should compile without a problem.

Compiler problem: std::size_t in C++ instead of size_t in C.

Nothing to do with FOAM, just the new compilers starting with strict checking.

Hi prof. Jasak,

yep... :) I've actually figured that one out... Let me quote myself (I've always wanted to do this :) ):

Btw, running OpenFOAM on Fedora 15 is not a good idea, reverting to an older version of gcc messes up the new Gnome 3 shell.
