Subject: [PATCH] makedumpfile: fix Makefile for eppic_makedumpfile.so build
Date: Mon,  9 Jun 2014 15:33:16 +0800	[thread overview]
Message-ID: <1402299196-15720-1-git-send-email-chaowang@redhat.com> (raw)

When libeppic isn't installed on a standard location, building
eppic_makedumpfile.so with -leppic directly doesn't work.

Add LDFLAGS to build arguments, so that one can pass LDFLAGS="-Ldir
-Idir" to tell where to search for libeppic library and its header
files.

For example, if eppic source is installed on the same directory level
with makedumpfile as the following:

makedumpfile
├── arch
└── eppic_scripts
eppic
├── applications
└── libeppic

After compiling libeppic, one can use the following command to build
eppic_makedumpfile.so:

make LDFLAGS="-I../eppic/libeppic -L../eppic/libeppic" eppic_makedumpfile.so
