Build V8 on linux with GCC and system headers

[Georgi Sotirov]

Is there a way to build V8 natively on linux with system's compiler (GCC), library and headers? How to make the build use GCC, system headers from /usr/include, instead of /usr/src/v8/build/linux/debian_jessie_i386-sysroot/usr/?

For information I'm trying to build on Slackware Linux.

[Jakob Kummerow]

To use the system compiler, try:

$ make ia32.release GYPFLAGS=-Dclang=0

I don't know whether it will also use system headers though.

(Also note that the make/GYP-based build is deprecated. The new hotness is "gn"; see the wiki for instructions. tools/dev/gm.py gives you an experience that's very similar to the Makefile.)

Thanks! It works and build is in progress... are these flags described somewhere?

Yes, I'll try it later, but for now I prefer something that I'm more familiar with like make :-)

Arghhhh... Any way to disable turning of warnings to errors?

Found it myself :-)

make ia32.release GYPFLAGS='-Dclang=0 -Dwerror='

[Jakob Kummerow]

...or simply: make ia32.release werror=no

are these flags described somewhere?

Yes, in the Makefile :-)
