[PATCH] scripts: unset LIBRARY_PATH and LPATH

[PATCH] scripts: unset LIBRARY_PATH and LPATH

[Erik Inge Bolsø]

[-- Attachment #1: Type: TEXT/PLAIN, Size: 641 bytes --]

Fooling around with crosstool-ng hg version, I happened to get gcc 
configure to yell at me right off. Promising.

The breakage is in build-cc-core-pass-2, saying
[ERROR]    configure: error: 
[CFG  ]    *** LIBRARY_PATH shouldn't contain the current directory when
[CFG  ]    *** building gcc. Please change the environment variable
[CFG  ]    *** and run configure again.

I figure this could bite others, and I see no good reason for LIBRARY_PATH 
to be set at this point.

The reason I had them set in the first place was due to some nvidia OpenCL 
libraries.

Patch attached to unset these two.

scripts: unset LIBRARY_PATH and LPATH

These environment variables set search path for gcc at link time, which can break the build.

Sorry it took so long to apply your patch.

Next time, would you please use 'hg email' to send your patches, that will
send the patches in-line so it's easier to review and catch my eye).
There a tuto on how to do that in: docs/C - Misc. tutorials.txt.

Thank you!

Regards,
Yann E. MORIN.

PS. It seems my send-an-email-for-applied-patches script is now working! :-)
YEM.
