remove automatic feature detection #250

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago
I added code to gyp to attempt to auto-configure various system settings (like 
LINKER_USES_ICF).  With more perspective I think this was a mistake.  It makes 
things unpredictable as to which flags you're getting and it is complicated in 
the presence of cross compiles.  We should remove all of the system test code 
from gyp.

linux: drop LINKER_SUPPORTS_ICF flag

Rather than attempting to detect this at gyp time, leave it up to
the author of the gyp file to set or unset this flag.

linux: drop detection of --threads flag to the linker

This is now the responsibility of the gyp file to set.

make: drop all system tests

Rather than probing for ARFLAGS at gyp type, just always use "crs".
This will change systems that use thin archives to start using "fat"
archives.  A subsequent change will allow the outer project to control
this setting.

Done?

I had to revert r1208.  Chrome on Linux can't build without thin archives 
anymore, but android can't build *with* thin archives, I think.

Skia is interested in building a static library that can be linked against 
outside of gyp.  We need a way to optionally build a target as a "fat" archive. 
 Right now, it looks like there's no way around the hard-coded -T flag.  Is 
there, or will there be, a workaround?  Making local changes doesn't cut it.

Evan, the android version of ar should work fine with thin archives now, but 
the autodetection logic fails because the `%(cc)s test.a` step fails to link 
due to android CRT weirdness.

I can fix it by changing the link command there to be `%(cc)s -r -nostdlib 
test.a` (which also works on Linux) and then android is correctly detected as 
supporting thin archives, but would it be better to just remove the test and 
always use the thin flag?

I think it'd be nice to just always use the thin flag (I even tried to do this 
in the past, but ran into this Android problem).  You might want to figure out 
whether it breaks Mac.  It might be worth just hardcoding on for Linux and off 
for others.

Fixed in gyp r1507, rolled into chromium with r158862. make builds now always 
use thin archives on Linux and Android, and system_test is gone.
