Error: '_' was not declared in this scope

[Vassilios Grigoriadis]

Hi,

I built successfully from source libmgl. I added Fl_MathGL.h to my project, added the include path and the parameter to link to the library.

When I compile I get the following error:

Error: '_' was not declared in this scope

for the line:

void toggle_alpha() { toggle(alpha, alpha_bt, _("Graphics/Alpha")); }

and all lines that include _("sometexthere")

I am using fltk v1.3.6 and mathgl v2.4.4 in voidlinux

Any suggestion are welcome.

Hi,

There is a definition of "_" macros in mgl2/define.h (see https://sourceforge.net/p/mathgl/code/HEAD/tree/mathgl-2x/include/mgl2/define.h#l80 ). This is do nothing or call gettext function for translation. So, it looks as if you don't take the whole MathGL library :) .
