Scons build fails at c++ compiler check.

[JureBericic]

Cannot build the analyzer using the scons. It fails with:

    Got a 64-bit processor, I can do a 64-bit build in theory...
    64-bit Linux build
    Checking whether the C++ compiler works... no
    !!! Your compiler and/or environment is not correctly configured.

However, the build using make works fine.

Hi Jure,

As the message says, there appears to be something about your C++ environment that is not configured the way that scons required (which admittedly is not very much). Can you send me (brash@jlab.org) the file config.log that is produced when you run scons?

Cheers, E.

Confirmed on my desktop machine. Same message. I'm using RHEL 7 and scons 2.5.0 from EPEL. The scons package was last updated in August of this year. Earlier this year, scons builds worked just fine on my box. Nothing obvious in the compiler environment has changed since then.

I’ll figure out what is going on.

Ole, can you tell me what compiler version your RHEL 7 system is using, and also could you post the config.log file that is created when you type scons?

I have tested with an EL6 system and scons2.5.0 and it works ok for me. I will create an EL7 virtual machine tonight and try to recreate the behavior. I tried initially to use ifarm1402 (which is Centos7.2) at jlab, but it looks like they don’t have ROOT available for it yet … argh!

Cheers, E.

Hi Ed,

the compiler version:

$ gcc --version gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-4)

and config.log:

$ cat config.log file /home/ole/Develop/analyzer/SConstruct,line 163: Configure(confdir = .sconf_temp) scons: Configure: Checking whether the C++ compiler works... scons: Configure: ".sconf_temp/conftest_0.cpp" is up to date. scons: Configure: The original builder output was:	.sconf_temp/conftest_0.cpp <-
	int main()
	{
	return 0;
	}

c++ -o .sconf_temp/conftest_0.o -c -std=c++11 -O "-Wall -Woverloaded-virtual" -Wextra -Wno-missing-field-initializers -Wno-unused-parameter -Wno-deprecated-declarations -m64 -pthread -rdynamic -DNDEBUG -DLINUXVERS -DHAS_SSTREAM -I/home/ole/evio-4.4.6/Linux-x86_64/include -Isrc -Ihana_decode -I/usr/include/root .sconf_temp/conftest_0.cpp c++: error: unrecognized command line option ‘-Wall -Woverloaded-virtual’ scons: Configure: no

Ahh ... I think we're on to something here.

Thanks for looking into this.

Ole

Interesting.

On ifarm1402, scons uses g++ rather than c++, but c++ and g++ are the same exact executable. Is this true on your RHEL7 system? What are the outputs of c++ —version and g++ —version?

Cheers, E.
