Outreachy Internships

[Iwona Kotlarska]

Hi everyone,
I'm new to contributing to Wine and I would like to apply to Outreachy 
Internship. I'm generally comfortable with C, but I don't understand 
Wine's code yet.
I tried to download and build Wine on my computer, I followed this: 
https://wiki.winehq.org/Developer_FAQ#How_do_I_download_and_build_the_very_l...
and make fails (linking actually) with undefined reference to yywrap in 
function yylex in file programs/winhlp32/macro.lex.yy.c line 1032. I'm 
using gcc 5.4.0.
Could anyone help me solve this compilation issue?
And suggest some small bugs to work on after succesfully compiling wine?
Thanks in advance for help!

It's a bug in Flex; try downgrading to Flex 2.6.2 or wait a few months
for Flex 2.6.4.

Wine is big and complicated, so you'll want to pick something very
specific for your Outreachy proposal. Good luck!

Hi Iwona,

If you are using Arch or Antergos, the package maintainer for flex has
released a patched version of flex-2.6.3 that avoids that particular
bug. Make sure you update your flex package to 2.6.3-2.

Hi Iwona,

As others have mentioned, that's a Flex bug, see:
