No code optimization in Makefile

[bol-van]

No -O2, -O3. 'make' produces unoptimized, big and slow code.

Use make DEBUG=no to produce binary with optimizations.

[bol-van]

I don't think it's a good idea to make DEBUG by default.
In compile guide there's no indication that DEBUG=no is required for production builds.

Following instruction a user gets bad binary

[Vort]

I agree that documentation should be improved.
By the way, it is located in repository nearby:

If user build binary himself, I assume that user do it not just for fun. That's why debug is enabled by default.

[bol-van]

User can do it for many reasons. For example, I do it because I use debian sid (unstable) , you do not have builds for sid, and mainteiners do not update i2pd fast.

Most programs expect configure/make to build, that's what most users expect

Use debuild --no-tgz-check -us -uc -b as described in documentation for Debian/Ubuntu.
In my cases (Bullseye, Bookworm) was -O2:
g++ -g -O2 -ffile-prefix-map=/home/user1/i2pd=. -fstack-protector-strong -Wformat -Werror=format-security -Wall -pedantic -std=c++17 -fPIC -maes -MMD -MP -DUSE_UPNP -D__AES__ -DOPENSSL_SUPPRESS_DEPRECATED -DGITVER=2.50.1-7-g c5cab05a -Ilibi2pd -Ilibi2pd_client -Ii18n -c -o obj/libi2pd/api.o libi2pd/api.cpp

[bol-van]

Sure, there're many ways to make it properly.
I just emphasized that standard build way does not produce expected result as it does in most other programs
