Hello,
I am having the same problem as Jason with flex. On compiling, I get an error that says

undefined reference to `yyFlexLexer ...

when it is compiling the ansystofoam mesh conversion utility. If it makes a difference, I don't anticipate needing this specific conversion tool, can I tell Allwmake to somehow skip this and compile everything else? Or is the flexlexer something I need? As it is, everything up to that point compiles fine but the make exits with "Error 2" after the undefined reference noted above. Any help?
I tried using the previous version of flex from cygwin (2.5.33-1) but get the same error.

Thanks,
Kent

hi,
is there anyone that could help me with the installation of OF?
I have never used cygwin and i am having a problem following the instructions given in the cygwin.readme.
If anyone can help, i will appreciate it.

Thanks,
Andrea

PS Once version 1.5 comes out...will it work with cygwin?

It is amazing what you can learn when you actually read the posts... I found my answer on another thread.

The switch suggested there seems to have done the trick with the undefined yyFlexLexer::yywrap() problem.

Hi Hans Linqvist,

• What error message did you get when you ran Allwmake? Can you post it?
• Where is the exact installation directory of JDK?

Hi Takuya, the path to my jdk is:

C:\Program\Java\jdk1.6.0_06

When executing Allmake the error message is:

$ bashrc

Hi Hasse,

You most likely have to "source" the bashrc file into the current shell environment, instead of executing it directly.

source ~/openfoam/OpenFOAM-1.4/.OpenFOAM-1.4/bashrc

Takuya

[monroe]

Thanks Takuya, that did it, had to sourced the allwmake to

Hasse

[eno]

when run
~/openfoam/OpenFOAM-1.4/.OpenFOAM-1.4/bashrc
I have the following errors:
line 56: [: too many arguments
line 262: [: too many arguments

What can be the problem?

[7islands]

Hi Sean Bian,
Does your installation path contain a whitespace (e.g. C:\Documents and Settings\OpenFOAM)? If so could you try moving the path to the one without a whitespace.

Takuya,
Thanks. The files are installed in C:\cygwin\OpenFOAM... but this problem is solved and i think the sources are successfully compiled now.
A new problem is when I type FoamX in cygwin terminal i have the error:
Can't find FoamX configuration directory at /cygerie/c /Documents and Settings/user/.OpenFOAM-1.4/apps/FoamX

[7islands]

Sean Bian,
Just like the original Linux version, the Cygwin version by default assumes to be compiled and installed under $HOME/OpenFOAM and $HOME should not contain a whitespace.

Hi All,

I am trying to compile OpenFOAM-1.4.3 under cygwin. Everything looked normal until I got the following message after hours of compilation. Could any gurus give me any info what's wrong with my compilation? Many thanks!

Hi Paul!

1.4.3? As the patches posted above are for previous versions it is not sure that they are correctly applied. Make sure that they are.

Please check whether this is the first error message you get during compilation (I doubt it)

Bernhard

[7islands]

Probably he meant the 1.4-3.cygwin version. My current guess is the available memory was not enough to link finiteVolume (see my post on June 14, 2007 above), but can't say for sure until I see the first error message.

T

[paulchang]

Thanks, Bernhard and Takuya.

Sorry for the confusion. Takuya is right, I meant 1.4-3.cygwin.

I guess it is not because of the memory, which is 3.2 GB in my computer.

Is the installation of "cygserver" mandatory? Since I don't have administrator privilege, I skipped the step of installing cygserver.

[7islands]

Hi Paul,
You don't need cygserver unless you do parallel runs. As Bernhard said posting the first error message may be helpful.

Takuya

[paulchang]

Thanks, Takuya

After carefully checked the compiling output info and did more internet search, I modified line 286 of the file "os-misc.h" from extern "C" int gettimeofday (struct timeval *, struct timezone *) to extern "C" int gettimeofday (struct timeval *, void*), and the errors are less than before, but the compilation is still not successful.

I also noticed that almost all the errors are related to "cygwinGcc4DPOpt", which I didn't download (Is this file needed? Where can I download this package?)

BTW, how can attached a text file to my message?

[7islands]

cygwinGcc4DPOpt is just a target name so there's no such distribution to download.

If you could precisely track down the occurrence of the first error, just copy-and-pasting several ten lines of the log around there should be enough. But if you think it is insufficient and would like to post the whole log, see the Formatting section of the forum documentation at the pane left of this forum screen. Note the size of the attachment is still limited to 50 KBytes (IIRC).

Try creating a softlink:
ln -s flex flex++

[eno]

I gave up compiling ver1.4 and installed 1.3 binary with a nonworking FoamX. When i try to use paraFoam to view the cavity sample i just run, I can not open the controlDict.foam in the GUI. It keeps asking:
a reader for "...controlDict.foam" could not be found, please choose one...
Which one should I choose?

The 0 0.1 0.2 ...0.5 folds are in .../cavity
and controlDict.foam is in .../system
I have paraview3.2.1 installed in c:/program files/paraview3.2.1
