Syntax error: "(" unexpected

[byronpendason]

I'm trying to build SmallBasic in Termux. I retrieve code using git, and then run autogen.sh. The problem comes when trying to configure (trying to do it without sdl, since Termux doesn't have SDL support without jumping through some hoops to set it up. Lol). I keep getting the following Syntax error:

Syntax error: "(" unexpected

I initially thought maybe an unmatched parenthesis, but when I look over the code, that's not the case. Any ideas on how to get passed this?

It seems this is Android? Android uses mksh as the shell (sh is mksh). Try using another shell like bash, bash ./autogen.sh and bash ./configure
