We have a problem where the crossdev pkg-config wrapper scripts |
| 5 |
interfere with multilib. |
| 6 |
|
| 7 |
crossdev for example sets in their pkg-config wrappers: |
| 8 |
|
| 9 |
PKG_CONFIG_LIBDIR="${SYSROOT}/usr/lib/pkgconfig:${SYSROOT}/usr/share/pkgconfig" |
| 10 |
|
| 11 |
Now, SYSROOT is chosen from multiple conditions. When emerging a |
| 12 |
package, that happens to be "/" and thus results in: |
| 13 |
"//usr/lib/pkgconfig://usr/share/pkgconfig" |
| 14 |
|
| 15 |
Build systems like autotools will pick the crossdev provided |
| 16 |
"i686-pc-linux-gnu-pkg-config" for the 32bit ABI which will in turn |
| 17 |
override the eclass-exported PKG_CONFIG_LIBDIR and now effectively |
| 18 |
find the pkg-config files in /usr/lib64/... |
| 19 |
|
| 20 |
This is not a problem most of the time if the package just wants to |
| 21 |
get the libs to link against. |
| 22 |
|
| 23 |
However, every package that tries to access variables that are |
| 24 |
different between /usr/lib32/pkgconfig/foo.pc and |
| 25 |
/usr/lib64/pkgconfig/foo.pc like "libdir" will fail or produce |
| 26 |
unexpected results. |
| 27 |
|
| 28 |
That already happens for |
| 29 |
x11-libs/libva-vdpau-driver |
| 30 |
x11-libs/libva (https://bugs.gentoo.org/show_bug.cgi?id=500338) |
| 31 |
|
| 32 |
and there are probably more. |
| 33 |
|
| 34 |
A simple workaround is: |
| 35 |
PKG_CONFIG="pkg-config" emerge foo |
| 36 |
|
| 37 |
But I think that is not appropriate to set in the eclass. How can we |
| 38 |
solve this? Don't bikeshed. |
