#3375 closed enhancement (fixed)

Remove command line pre-processor defines

Command line defines defined by the build system make it difficult get a consistent view of the sources from other entities, e.g. static code analysis, code editors and reviews.

Command line defines are currently used here:

c/src/lib/libbsp/mips/hurricane/Makefile.am:libbsp_a_CPPFLAGS = $(AM_CPPFLAGS) -DRM52XX
c/src/lib/libbsp/mips/rbtx4938/Makefile.am:libbsp_a_CPPFLAGS = $(AM_CPPFLAGS) -DTX49
c/src/lib/libbsp/mips/jmr3904/Makefile.am:libbsp_a_CPPFLAGS = $(AM_CPPFLAGS) -DTX39
cpukit/pppd/Makefile.am:libpppd_a_CPPFLAGS = $(AM_CPPFLAGS) -D__BSD_VISIBLE -I$(srcdir)/../libmd
cpukit/libfs/Makefile.am:libjffs2_a_CPPFLAGS += -D__ECOS
cpukit/libfs/Makefile.am:libjffs2_a_CPPFLAGS += '-DKBUILD_MODNAME="JFFS2"'
cpukit/mghttpd/Makefile.am:# libmghttpd_a_CPPFLAGS += -DHAVE_MD5
cpukit/mghttpd/Makefile.am:libmghttpd_a_CPPFLAGS += -DNO_SSL -DNO_POPEN -DNO_CGI -DUSE_WEBSOCKET
cpukit/librpc/Makefile.am:librpc_CPPFLAGS = -D_RPC_read=read -D_RPC_write=write -D_RPC_close=close \
cpukit/libnetworking/Makefile.am:libnetworking_CPPFLAGS = -DINET -DNFS \
cpukit/libnetworking/Makefile.am:libc_CPPFLAGS = -DNOPOLL -DNOSELECT -D__BSD_VISIBLE -D_THREAD_SAFE
cpukit/libnetworking/Makefile.am:lib_CPPFLAGS = -DNOPOLL -DNOSELECT
cpukit/libnetworking/Makefile.am:lib_a_CPPFLAGS = $(AM_CPPFLAGS) $(lib_CPPFLAGS) -D__BSD_VISIBLE

What are you thinking of doing?

comment:2 Changed on 03/27/18 at 06:18:03 by Sebastian Huber

Move the defines to a header file.

comment:3 Changed on 03/27/18 at 23:09:52 by Joel Sherrill

For places where the source comes from other places (e.g. JFFS2, etc), what's the approach that doesn't modify the upstream source?

comment:4 Changed on 03/28/18 at 05:02:03 by Sebastian Huber

We just have to be careful to avoid potential conflicts with upstream merges. JFFS2 is the only area with an active upstream.

Replying to Sebastian Huber:
