[Lynx-dev] [PATCH] src/chrtrans: don't build host tools with target LDFL

From: Thomas Petazzoni
Subject: [Lynx-dev] [PATCH] src/chrtrans: don't build host tools with target LDFLAGS
Date: Mon, 7 May 2018 22:02:51 +0200

In a cross-compilation context, the LDFLAGS variable contains linker
flags used when building things for the target. However, the makeuctb
tool is built for the host machine, and therefore should not use the
same LDFLAGS as the target, which is why BUILD_LDFLAGS exist.

Using LDFLAGS when building a tool for the host can cause problems
when some flags in LDFLAGS are not supported by the host machine. For
example, if you're linking statically lynx for the target, but the
build machine does not support static linking:

gcc -I../.. -I../../src -I../../src/chrtrans -I../../WWW/Library/Implementation 
-I../../     -static  -o makeuctb makeuctb.o
/usr/bin/ld: cannot find -lc
collect2: error: ld returned 1 exit status
