[Buildroot] scons and check

[Sylvain Raybaud]

Hi

I'm trying to create a package for Galera, a library needed by mariadb
galera cluster. It builds with scons. Galera depends on check so I
created a package for this library too, which seems to build and
install correctly.

A few packages in buildroot already use scons (exfat, exfat-utils,
benejson, gpsd). Their build commands look like this:

FOO_SCONS_ENV = $(TARGET_CONFIGURE_OPTS)
FOO_SCONS_OPTS = "prefix=/usr"

define FOO_BUILD_CMDS
        cd $(@D) && \
	 $(FOO_SCONS_ENV) \
	 CROSS=$(TARGET_CROSS) \
	 $(SCONS) $(FOO_SCONS_OPTS)
endef

So I wrote my .mk file the same way. However scons does not seem to
find the Check library. Building galera fails with:

Checking for C header file check.h... no
Error: check header file not found or not usable

and corresponding config.log shows a "check.h: file not found" error.

Now the disturbing thing is that it only happens when I build on a
system on which check is not installed system-wise. If the build host
has check installed, galera builds. Does this mean that scons uses
host haeders instead of those provided by buildroot packages? Any idea
how to make it behave properly?

Cheers,

According to [1], you need to package check [2] in buildroot as well

It certainly means that galera will depend on host-check; I let you
check about the dependency on (target-) check.

Yes, I did that. Check is building and installing just fine in buildroot.

I made galera dependent on host-check. As a result check is built and
installed. The header is present in output/host/usr/include/check.h
and the .pc file in output/host/usr/lib/pkgconfig/check.pc.

Just to be sure I tried to also make it dependent on target check, it
didn't work either (check is installed on target but scons cannot find
it).

Cheers,

Sylvain

[Buildroot] scons and check

Well, the fact that it doesn't find it may also be due to the
SConstruct not doing the right thing. So make sure to really understand
how "check" is used by galera, and only that will allow you to know if
a host "check" or target "check" package is needed.

Installing a host-check just because it makes things "work" might be a
mistake.

Best regards,

Thomas

I had a similar problem recently, I had to change my SConstruct file, so that 
the CROSS variable is actually used in the target build process. The lines I 
added are:

if 'CROSS' in os.environ:
        cross = os.environ['CROSS']
        env.Append(CROSS = cross)
        env.Replace(CC = cross + 'gcc')
        env.Replace(CXX = cross + 'g++')
        env.Replace(LD = cross + 'ld')

Best,
Peter

Hi

Thank you very much. I think with this I fixed a number of other
problems I had not yet spotted. Scons was indeed looking for things in
the wrong place. However it still cannot find check :) But I think the
SConstruct should be fixed so I'll dig deeper and let you know.

Cheers,

Hi all,

I had to fix more things in SConstruct file and pass the proper
extra_sysroot argument to scons but I think I got it working. Thanks
again. I'll submit a bunch of patches for adding check, galera and
mariadb probably next week. Hopefully.

Cheers,

Sylvain
