compile error with Mac Xcode 14

[ftab]

This is with eRPC 1.10.0

I'm using a MacBook Air M1 (Apple Silicon), so the homebrew paths are different:

BISON_ROOT=/opt/homebrew/opt/bison FLEX_ROOT=/opt/homebrew/opt/flex BOOST_ROOT=/opt/homebrew/Cellar/boost/1.81.0_1 make -j

The error:

/opt/homebrew/Cellar/boost/1.81.0_1/include/boost/lexical_cast/detail/converter_lexical_streams.hpp:310:21: error: 'sprintf' is deprecated: This function is provided for compatibility reasons only.  Due to security concerns inherent in the design of sprintf(3), it is highly recommended that you use snprintf(3) instead. [-Werror,-Wdeprecated-declarations]

The workaround:

diff --git a/mk/flags.mk b/mk/flags.mk
index a42233d..3919b8e 100644

Until Boost reworks that library to no longer use sprintf, we have to add that flag.

Hi @ftab , could you print this in your terminal? I am curious what it will return:

uname -s

Also i would like to know your gcc and g++ version which i used to compile code...

I will try to talk to them related this change and based on that we can do decision.

So far we can fix this:

Guys from boost said that it will be fixed in next release. So i would like to not to add this workround flag. Maybe keep it as known issue with how to fix it info.

[Hadatko]

Maybe we can parse boost version and if it is smaller than 1.82 then apply macro.

Good to know Boost has a fix planned.

I am about to remove boost dependency. Then this issue should be solved.
