Now, the user of the Makefile is supposed to pass + -D_FILE_OFFSET_BITS=64 when largefile support is desired. + + * Use override CFLAGS += so that additional CFLAGS can be passed on + the command line. + + * Removed "forced" CFLAGS -O2, -g and -Winline. We don't want them by + default, and want the build system to use its own ones. + + * When creating the symbolic links bzegrep, bzfgrep, bzless and + bzcmp, don't link them to an absolute path, or they'll point to + some path on the build machine. + + * Provide an install target for the shared library, which creates the + appropriate symbolic links. + +Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> + +Index: b/Makefile +=================================================================== +--- a/Makefile ++++ b/Makefile +@@ -20,8 +20,7 @@ + RANLIB=ranlib + LDFLAGS= + +-BIGFILES=-D_FILE_OFFSET_BITS=64 +-CFLAGS=-Wall -Winline -O2 -g $(BIGFILES) ++override CFLAGS += -Wall + + # Where you want it installed when you do 'make install' + PREFIX=/usr/local +@@ -90,14 +89,14 @@ + cp -f libbz2.a $(PREFIX)/lib + chmod a+r $(PREFIX)/lib/libbz2.a + cp -f bzgrep $(PREFIX)/bin/bzgrep +- ln -s -f $(PREFIX)/bin/bzgrep $(PREFIX)/bin/bzegrep +- ln -s -f $(PREFIX)/bin/bzgrep $(PREFIX)/bin/bzfgrep ++ ln -s -f bzgrep $(PREFIX)/bin/bzegrep ++ ln -s -f bzgrep $(PREFIX)/bin/bzfgrep + chmod a+x $(PREFIX)/bin/bzgrep + cp -f bzmore $(PREFIX)/bin/bzmore +- ln -s -f $(PREFIX)/bin/bzmore $(PREFIX)/bin/bzless ++ ln -s -f bzmore $(PREFIX)/bin/bzless + chmod a+x $(PREFIX)/bin/bzmore + cp -f bzdiff $(PREFIX)/bin/bzdiff +- ln -s -f $(PREFIX)/bin/bzdiff $(PREFIX)/bin/bzcmp ++ ln -s -f bzdiff $(PREFIX)/bin/bzcmp + chmod a+x $(PREFIX)/bin/bzdiff + cp -f bzgrep.1 bzmore.1 bzdiff.1 $(PREFIX)/man/man1 + chmod a+r $(PREFIX)/man/man1/bzgrep.1 +Index: b/Makefile-libbz2_so +=================================================================== +--- a/Makefile-libbz2_so ++++ b/Makefile-libbz2_so +@@ -23,8 +23,7 @@ + + SHELL=/bin/sh + CC=gcc +-BIGFILES=-D_FILE_OFFSET_BITS=64 +-CFLAGS=-fpic -fPIC -Wall -Winline -O2 -g $(BIGFILES) ++override CFLAGS += -fpic -fPIC -Wall + + OBJS= blocksort.o \ + huffman.o \ +@@ -37,8 +36,11 @@ + all: $(OBJS) + $(CC) -shared -Wl,-soname -Wl,libbz2.so.1.0 -o libbz2.so.1.0.6 $(OBJS) + $(CC) $(CFLAGS) -o bzip2-shared bzip2.c libbz2.so.1.0.6 +- rm -f libbz2.so.1.0 +- ln -s libbz2.so.1.0.6 libbz2.so.1.0 ++ ++install: ++ install -m 0755 -D libbz2.so.1.0.6 $(PREFIX)/lib/libbz2.so.1.0.6 ++ ln -sf libbz2.so.1.0.6 $(PREFIX)/lib/libbz2.so ++ ln -sf libbz2.so.1.0.6 $(PREFIX)/lib/libbz2.so.1.0 + + clean: + rm -f $(OBJS) bzip2.o libbz2.so.1.0.6 libbz2.so.1.0 bzip2-shared |
