Cannot compile in Fedora 28

[izauddin]

Hi,

I cannot build this on Fedora 28, got the following error when running make

Have follow the instruction at http://www.jt360.net/home/tech-articles/install-and-configure-the-telegram-client-on-raspberry-pi but still giving the above problem.

Or any one have rpm package for Fedora 28 ?

Facing same issue on Arch Linux - #1542.

Same issue here also with Fedora 28...

PS: @izauddin, wrap your output in ``` (three consecutive backticks before and after your code) to make it a bit easier to read.

Ok, faced the same problem with the following error log

For a dangerous workaraound you have to add -Wno-error=cast-function-type to COMPILE_FLAGS inside your Makefile so it'll look something like this

COMPILE_FLAGS=${CFLAGS} ${CPFLAGS} ${CPPFLAGS} ${DEFS} -Wall -Werror -Wextra -Wno-missing-field-initializers -Wno-deprecated-declarations -fno-strict-aliasing -fno-omit-frame-pointer -ggdb -Wno-unused-parameter -fPIC -Wno-error=cast-function-type

And also don't forget to downgrade openssl to openssl10

sudo dnf install compat-openssl10-devel --allowerasing -y

fix it this way:

The correct way to set CFLAGS in configure is:

./configure --prefix=/usr CFLAGS="$CFLAGS -w"

which on 64bit gives CFLAGS of:

CFLAGS="-march=x86-64 -mtune=generic -O2 -pipe -fstack-protector-strong -fno-plt -w"

from archlinux.org

[haghighi]

On Fedora 28:

$ ./configure --disable-openssl --prefix=/usr CFLAGS="$CFLAGS -w"
$ make

[sitano]

GCC 8.1.1 does not like incompatible function type casts and reports many Werror=cast-function-type errors. Use env CFLAGS="-Wno-cast-function-type" ./configure

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

[sukhrob322]

On Fedora 28:

$ ./configure --disable-openssl --prefix=/usr CFLAGS="$CFLAGS -w"
$ make

This solved my issue. Before running this command, also installed libssl1.0-dev

[Bost]

On Fedora 28:

$ ./configure --disable-openssl --prefix=/usr CFLAGS="$CFLAGS -w"
$ make

This solved my issue. Before running this command, also installed libssl1.0-dev

I had to install libgcrypt20-dev and libssl-dev

On Fedora 28:

$ ./configure --disable-openssl --prefix=/usr CFLAGS="$CFLAGS -w"
$ make

fixed issue in Centos8
