[Buildroot] BR2_PACKAGE_EXPAT

[Chris LaRocque]

Hello

I am building for Beaglebone black and everything is working; except that
now I need libexpat for the target and it is not in sysroot even
though BR2_PACKAGE_EXPAT=y. I searched the archives and found threads
discussing issues with GDB and not wanting libexpat in sysroot but did not
follow why this is an issue.

Could someone enlighten me on why having target libexpat in sysroot is an
issue and also why I can't find the libraries?

Thanks

I'd say there is something you did incorrectly, because the expat
package definitely installs the expat library and headers to staging.

$ cat > .config <<EOF

If you're still having an issue, please:

 (1) Do a clean rebuild, using "make clean all".

 (2) Provide your complete .config file.

 (3) Post on some pastebin site (like http://code.bulix.org) the entire
     build log.

Best regards,

Thomas
