Re: [gnugo-devel] GNU Go 2.6 compilation issue on Debian GNU/Linux

[James Dempsey]

Thanks Luis, I replaced `-lang-c89` with `-std=c90` and that let me compile successfully.

I wanted to try compiling a weaker version :). Even with setting `--level` for 3.8 I see no real difference in strength/rank.

James,

is there any reason why you are trying to build even older versions?

The error there is that that specific compiler flag is not valid for this version of GCC. I'd guess you would have to look at how to switch it for something else to see if it would still build, this seems to be implying it should be using the C89 standard, which you can do in different ways now:

https://gcc.gnu.org/onlinedocs/gcc/Standards.html

"-ansi, -std=c90 or -std=iso9899:1990"

I'm trying to chat with folks from GNU to see if we can sort out making a new release of GNU Go to at the very least solve some compilation issues and make it build again, hopefully have something happen soon on it.

Best regards,

Hello,

I'm experiencing another compilation issue, this time for GNU Go 2.6 on Debian GNU/Linux 11 (bullseye).

gcc is

gcc (Debian 10.2.1-6) 10.2.1 20210110

Error is:

gcc -DHAVE_CONFIG_H -I. -I. -I.. -I../engine -I../interface    -g -O2 -Wall -W -Wpointer-arith -Wbad-function-cast -Wcast-qual -Wcast-align -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wmissing-declarations -Wp,-lang-c89 -c sgf.c
cc1: error: command-line option ‘-lang-c89’ is valid for the driver but not for C
make[2]: *** [Makefile:155: sgf.o] Error 1
make[1]: *** [Makefile:158: all-recursive] Error 1
make: *** [Makefile:306: all-recursive-am] Error 2

One again, not a C programmer and couldn't exactly make sense of the answers I had searched for.  Any help would be appreciated.

Thank you.
