Bug 263901 – dev-libs/libusb: Fix pkg-config file for cross-compilation

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Sven 'sleipnir' Rebhan 2009-03-26 20:39:05 UTC]

The libusb.pc file contains an absolute path to /usr/lib which makes cross-compilation very hard. The following patch fixes this misbehaviour introduced by a fixed path in the ebuild.

Reproducible: Always

Fix for the libusb pkg-config file 

Fix the libusb.pc file for cross-compilation by replacing the fixed path specified in the ebuild. Tested with armv4tl-softfloat-linux-gnueabi.

i would rather have cross-fix-root handle munging here than attempt to fight a never ending battle with .pc files

libusb is a problem for sure. But I'm only seeing a few problem pc files.
libusb, libbluetooth and udev are the only 3 that come to mind out of the 1500 or so pkgs that xcompile that I've worked with.

With that said.. I happen to think the solution of using '${exec_prefix}' quoted out is rather elegant and maybe should be done on a near tree wide basis to replace the hard coded /usr prefix stuff.

you'll have to file a bug about that to change the econf behavior.  there's nothing to change in libusb as ive removed that --libdir line.

[Comment 5 Sven 'sleipnir' Rebhan 2009-03-30 10:55:10 UTC]

Removing the --libdir also solves the .pc issue. So if you're confident that removing this line is valid (I wasn't so I choose the patch above), you can close the bug as resolved in -r5.

I can confirm libusb-0.1.12-r5 compiles fine here.

[Comment 7 SpanKY 2009-03-30 20:18:20 UTC]

i couldnt see any history as to why the libdir was added in the first place, and the resulting build appeared to be the same, so i dropped it
