problems while invoking flex
Hi there,
i am trying to compile OpenFOAM-1.5-dev on Scientific Linux 5, 64bit. The third party packages have successfully been compiled and linked, but starting "Allwmake" in the OpenFOAM-1.5-dev directory, i almost immediately trap into some error messages: (...) + wmake libso triSurface flex: unknown flag '-'. For usage, try flex --help mv: cannot stat `lex.yy.cc': No such file or directory Does anyone have a clue? Best regards, Jan |
...old flex
Hi Jan,
You probably have an old version of flex. Dragos |
using version 2.5.4 seems to work. Thanks a lot!

2.5.4.... uh, that's old!
According to flex website (http://flex.sourceforge.net/) this version was released in 1997. The latest version available is 2.5.35, released last year. There are some memory leaks associated with older flex versions, so it would be a good idea to update. Dragos |
you`re right. seems like a good idea to switch to something newer...
