[Cppcms-users] undefined reference to `cppcms::widgets::file::filename(booster::regex const&)'

[<cn...@gr...>]

Hi!

I add file widget in form:

cppcms::widgets::file picture;

And enforce check on file name extension:

picture.filename(booster::regex::regex(".*\\.(jpg|jpeg|png)"));

The compiler/linker complains:
------------------
g++ -Wall app.cpp view.cpp -o app -lcppcms -lbooster
/tmp/ccFMAK7N.o: In function `content::info_form::info_form()':
hello.cpp:(.text._ZN7content11info_formC1Ev[content::info_form::info_form()]+0x140): undefined reference to `cppcms::widgets::file::filename(booster::regex const&)'
collect2: ld returned 1 exit status
make: *** [app] Error 1
