Unable to compile on Arch Linux due to compilation error; _tgl_do_send_photo function

[FredrikAugust]

Trying to compile with makepkg -cs on arch linux (Linux 4.17.3-1-ARCH).

Output is as following:

tgl/queries.c: In function ‘_tgl_do_send_photo’:

Have the same compilation error.

Same problem...

GCC 8.1.1 (on Arch Linux) does not like this and reports many Werror=cast-function-type errors. Use env CFLAGS="-Wno-cast-function-type" ./configure

Have the same compilation error.

I've fixed the errors in my forks at https://github.com/kenorb-contrib/tg & https://github.com/kenorb-contrib/tgl

For ubuntu 19.04 same but should run ./configure with --disable-openssl
