Open source supplicant does not build under RHEL 6 x86_64

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



  Although adding "-fPIC" to CFLAGS does fix the build, I don't think 
should be necessary -- a better solution would be to update the patch to 
add in "-fPIC" where needed in the Makefile(s).  I can look into this.  
(Before I tried with CFLAGS set to the rpmbuild-default ones, or with no 
CFLAGS at all.)

Also I was curious if the changes in this patch have been proposed upstream?
