Build error on Solaris

[yvoinov]

With GCC 5.5:

make

cc -m64 -O3 -std=gnu11 -Wall -mpclmul -march=native -mfpmath=sse -mssse3 -fno-strict-aliasing -fno-strict-overflow -fwrapv -DAES=1 -DCOMMIT=\"2fd27cb0753c62e5766c86db28f2acc1d755547f\" -D_GNU_SOURCE=1 -D_FILE_OFFSET_BITS=64 -iquote common -iquote . -c -MP -MD -MF dep/mtproto/mtproto-proxy.d -MQ objs/mtproto/mtproto-proxy.o -o objs/mtproto/mtproto-proxy.o mtproto/mtproto-proxy.c cc: Warning: GCC option -mpclmul ignored. Suggest using -xarch=aes cc: Warning: Option -mfpmath=sse passed to ld, if ld is invoked, ignored otherwise cc: Warning: Option -fno-strict-overflow passed to ld, if ld is invoked, ignored otherwise cc: Warning: Option -fwrapv passed to ld, if ld is invoked, ignored otherwise cc: Warning: Option -quote passed to ld, if ld is invoked, ignored otherwise cc: Warning: Option -quote passed to ld, if ld is invoked, ignored otherwise cc: refused to overwrite input file by output file: objs/mtproto/mtproto-proxy.o make: *** [Makefile:78: objs/mtproto/mtproto-proxy.o] Error 1

It seems as Makefile error.

Ah, I see. This is not portable code, will not build on Solaris in any way. Sorry and sadly.

Guys, add BSD support, please!

[yvoinov]

At least.

Most better make fully portable code - will be more proxies. ;)

There's no good reason why a program like this shouldn't compile and run on any *nix type system. Its only dependencies are openssl and zlib ...

[yvoinov]

Yes. It should be portable. But it not.

@marmulak is using epoll a good reason?

[marmulak]

Well I'm looking into this a little bit and apparently epoll is not available for FreeBSD and apparently not in its Linux emulation layer either (I only saw a brief reference to this so I'm not sure), but BSD systems have their own function, kqueue, which appears to do what epoll does. MTProxy can support multiple platforms. Obviously BSD is a worthwhile target, so you might want to add the ability to compile with kqueue on BSD systems, or search for an alternative method to get it to work.

http://people.eecs.berkeley.edu/~sangjin/2012/12/21/epoll-vs-kqueue.html

^ According to this guy, kqueue is better anyway. :)

Apparently there's more than one article about why epoll sucks: https://idea.popcount.org/2017-02-20-epoll-is-fundamentally-broken-12/

[yvoinov]

(and there is not only BSD and Linux nix-like OS on market presents - also /dev/poll OS, poll etc.... libevent also inventer already ;-))

So perhaps libevent can provide the necessary abstraction to make the software cross-platform? True there are many OS's out there. I'm particularly interested in BSD as I have a BSD server I would like to run this on, and actually it doesn't seem like a totally unreasonable expectation. A great many servers run BSD, and perhaps even Windows support can be added as well.

[stek29]

@marmulak I just wanted to show you the reason why it doesn't work on BSDs now, not the reason it can't work there. Nobody is going to rewrite all of this with libev/kqueue -- just use alternative implementations.

Guys, I built in FreeBSD 12 with gmake , got the same issue.
