kostya-sigar build failure

[zcater]

Hello.
I come here from trying to update diaspora. I have little to no knowledge with ruby stuff so please excuse any wrong assumptions.

I tried both 2.0.0 and 2.0.2 and the build fails.

Here are the build logs: 2.0.0 and 2.0.2

hm, what is your os, ruby version, i just ok install it on ruby 2.3.1.
gem install sigar also failed?

[zcater]

Sorry, I should've posted these from the beginning.

I'm on Gentoo with glibc-2.26, gcc-6.4.0, ruby-2.3.7.

Trying to build sigar seems to have the same issues.

Build log for gem install sigar

seems you have no functions major and minor in stdlibs.

i find in my /usr/include/sys/types.h this functions:

static inline __int32_t  major(__uint32_t _x)
{
  return (__int32_t)(((__uint32_t)_x >> 24) & 0xff);
}

static inline __int32_t  minor(__uint32_t _x)
{
  return (__int32_t)((_x) & 0xffffff);
}

can you try git clone this rep, then rake build, then add this functions or from http://unix.superglobalmegacorp.com/Net2/newsrc/sys/types.h.html, to linux_sigar.c and rake build again.

[zcater]

That file is from glibc.

From a quick google search it seems a common issue with glibc-2.26.

For example in https://jira.mongodb.org/browse/SERVER-29855 they seem to be recommending to also include sys/sysmacros.h.

[kostya]

so if you include sys/sysmacros.h in linux_sigar.c, this is fixed?

[zcater]

This is the build log for rake build of this repo after I added sys/sysmacros.h.

Looks ok-ish to me.

[kostya]

i push gem kostya-sigar 2.0.3.test, can you test it. using solutions from this https://wiki.gentoo.org/wiki/Glibc_2.26_porting_notes/sysmacros.h.

[zcater]

Unfortunately it's still not building. The log looks the same with 2.0.3.test.

[kostya]

this is strange because i just add this fix https://wiki.gentoo.org/wiki/Glibc_2.26_porting_notes/sysmacros.h

[kostya]

[zcater]

It works. Thank you!
