Guacamole Compilation Error on Fedora 24

scottalanmiller

Computing Apache Guacamole 0.9.9 on Fedora 24 or Korora 24 with GCC 6 results in:

/usr/include/glib-2.0/gobject/gparam.h:166:33: error: enumerator value for 'G_PARAM_DEPRECATED' is not an integer constant expression [-Werror=pedantic]
   G_PARAM_DEPRECATED          = 1 << 31
                                 ^
cc1: all warnings being treated as errors
Makefile:523: recipe for target 'libguac_terminal_la-display.lo' failed
make[2]: *** [libguac_terminal_la-display.lo] Error 1
make[2]: Leaving directory '/tmp/guacamole-server-0.9.9/src/terminal'

make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory '/tmp/guacamole-server-0.9.9'
Makefile:394: recipe for target 'all' failed
make: *** [all] Error 2

This is caused by a compatibility issue with GCC 6.

Looks like a known issue.

Looks like you can work around that by compiling with "-Wno-error=pedantic".

Yeah, tried that and no luck.

oh duh, it was off screen. I guess i need some sleep..

So strange even the GCC 6 documentation implies that -Wno-error=pedantic should cause -Werror=pedantic warnings to not be treated as errors.

"This switch takes a negative form, to be used to negate -Werror for specific warnings; for example -Wno-error=switch makes -Wswitch warnings not be errors, even when -Werror is in effect."

https://gcc.gnu.org/onlinedocs/gcc-6.1.0/gcc/Warning-Options.html#Warning-Options

I would guess if you really want to install you could remove -Werror from AM_INIT_AUTOMAKE (or add -Wno-error=pedantic)
