Hallo all,
I have some problems with compilation of OF1.4.
It seems to be problem in new STL.

Here is the top most error:

make: *** [Make/linuxGcc4DPDebug/readSTLASCII.o] Error 1

Additional info:
- I used patch for OpenFOAM-1.4/src/triSurface/triSurface/interfaces/STL/readSTLASCII.L
http://www.cfd-online.com/cgi-bin/Op...w.cgi?126/4189
- OF-1.3 compiles smoothly
- I use gcc411 not 412 (but assume it doent matter)
- Gentoo box (possibly all debian branch also affected with this error)

It seems to be another namespace conflict,
but i dont know how to correct it

Please help. Any hint appreciated.

I've seen the same thing on my SuSe-10.1 and ended up re-introducing foamFlex++ we had in previous versions. This was patched up to sort out similar problem with the standard flex (which does not seem to be developed any more) and it fixed my stuff.

Not sure if this will remain - still investigating in the light of Martin's RedHat suggestions.

Hi Hrv,

Thanks for hint. I will try to still foamFlex
from OF1.3 and come back in case of problems.

thanks
rafal

(BTW I didnt see anywhere information
removing foamFlex, but it is missing from utils)

Hi Hrv,
Thanks for the tip. It works. It compiles.

Here is rough howto in case someone has the
same problem like me:

* copy
~/OpenFOAM/OpenFOAM-1.3/applications/utilities/miscellaneous/foamFlex
to
~/OpenFOAM/OpenFOAM-1.4/applications/utilities/miscellaneous

* add the following lines in ~/OpenFOAM/OpenFOAM-1.3/src/Allmake:

cd $FOAM_APP/utilities/miscellaneous
wmake exe foamFlex
cp foamFlex/FlexLexer.h $FOAM_SRC/OpenFOAM/lnInclude
cd $FOAM_SRC


before the line
(cd Pstream ; ./Allwmake)

* make wmake to use foamFlex++ instead of flex++:
in ~/OpenFOAM/OpenFOAM-1.4/wmake/rules/General
the following files: flex++ and flex++.test
change: flex++
to: foamFles++

Hope that helps to someone.


Now i still do not run OF14 i hit some runtime
error which I am still trying to solve.

rafal

PS. Now i appreciate extensive path settings in OF
I can compile one version and work on the other
Once again I have to say about OF -
Great Piece of Code

Hi,

I also have some problems compiling 1.4.1-dev on Redhat. (64 Bits).

I get the following error message:

I uncommented the yywrap function in the corresponding .L file, but this gives troubles in the compiling proccess later on (as to be expected).

Did anybody have the same troubles? The flex++ version is 2.5.4

[mwibmer]

sorry, I found a related topic at

http://www.cfd-online.com/OpenFOAM_D...tml?1217020603

I replaced
"int yywrap()"
with
"extern "C" int yywrap()"

the compilation is continuing...
