resetting CFLAGS and CXXFLAGS in a PKGBUILD kills makepkg [solved]

graysky · 2011-02-03 21:26:40

I'm experiencing a very odd error when I try to build the nvidia package. I have added the following two lines which simply redefine the CFLAGS and CXXFLAGS:

CFLAGS="-march=x86_64 -mtune=generic -O2 -pipe"
CXXFLAGS="${CFLAGS}"

When I issue the standard makepkg -s I am presented with this very odd error:

==> Starting build()...
Creating directory NVIDIA-Linux-x86_64-260.19.36-no-compat32
Verifying archive integrity... OK
Uncompressing NVIDIA Accelerated Graphics Driver for Linux-x86_64 260.19.36.....................................................................................................................
The kernel you are installing for is a Xen kernel!

The NVIDIA driver does not currently work on Xen kernels. If 
you are using a stock distribution kernel, please install 
a variant of this kernel without Xen support; if this is a 
custom kernel, please install a standard Linux kernel.  Then 
try installing the NVIDIA kernel module again.

*** Failed Xen sanity check. Bailing out! ***

make[1]: *** [build-sanity-checks] Error 1
make: *** [module] Error 2
    Aborting...

If I comment those two lines out, it builds just fine... what is up?

Not that this should be making a difference:

There is a typo in the PKGBUILD:

CCXFLAGS="${CFLAGS}"

graysky · 2011-02-03 21:36:26

@Allan - good catch. But you're right, it seems as though this nvidia package doesn't tolerate me making this change. I have done this successfully with many other packages. Is there a method to clear the values for those two variables, then assign them or am I barking up the wrong tree?

Allan · 2011-02-03 21:47:13

Well... it should work... try adding "export" in front of those lines.

graysky · 2011-02-03 22:04:59

@Allan - tried your suggestion but the result was the same... perhaps I should kill the line in the Makefile that calls that xen check and call it good?

Simple logical reasoning: You are using what is meant to be the default settings in /etc/makepkg.conf. If something breaks, that means what you are using in the PKGBUILD does not match with the defaults.

This line:

CFLAGS="-march=x86_64 -mtune=generic -O2 -pipe"

Should be:

CFLAGS="-march=x86-64 -mtune=generic -O2 -pipe"

Shheesh seems difficult to resolve that difference from here

Yes, tiny mistakes like this are easy to make. I guess that's why Linux From Scratch repeats multiple times in their guide to copy/paste instead of writing out commands.

You're right (good eye). Works fine now. Thanks!
