[foam-extend.org] undefined reference to `yyFlexLexer::yywrap()'

sariug · July 16, 2018, 06:35

Hello I am receiving the error below, while installing new solver. I have already search everywhere and updated flex++. The reason I opened a new topic is that there is no problem with respect to a .so file. so really confused.

n/foam/foam-extend-3.1/lib/linux64GccDPOpt/libtriSurface.so: undefined reference to `yyFlexLexer::yywrap()'

Quick answer: Quoting from here: https://openfoamwiki.net/index.php/I...end-3.1/Ubuntu

Note: Before running Allwmake.firstInstall, you will need to run the following command to fix an issue with the Flex version:

Code:

find src applications -name "*.L" -type f | xargs sed -i -e 's=\(YY\_FLEX\_SUBMINOR\_VERSION\)=YY_FLEX_MINOR_VERSION < 6 \&\& \1='

An other solution is to have a flex version < 2.6
2.5.35 is ok for example
