[Xenomai-core] Undefined 'pc_sysrootdir' in libxenomai_posix.pc ?

2011-09-12 Thread varname 
Trying to use pkg-config with 2.6.0-rc2 results in the following error 
message:


  Variable 'pc_sysrootdir' not defined in 
'/home/test/usr/xenomai-2.6.0-rc2/lib/pkgconfig/libxenomai_posix.pc'


Same behaviour in rc1.

Removing ${pc_sysrootdir} seems to work, but I'm not sure that is the 
correct fix for this.

 No, the correct use of pkg-config is to pass the PKG_CONFIG_SYSROOT_DIR
 environment variable.
 
 if the staging variable contains the directory which was used as DESTDIR
 when installing xenomai, you should run pkg-config with the following
 environment variables set:
 
 PKG_CONFIG_LIBDIR=${staging}/usr/lib/pkgconfig:${staging}/usr/share/pkgconfig
 
 PKG_CONFIG_SYSROOT_DIR=${staging}

Right, that explains it. Sorry for the noise.
