Hi Chuck, I have a problem using libtool 2.2.6a. I've just tried to build the latest file(1) for Cygwin 1.7 using gcc-4. Since gcc-4 is still in flux I decided to build with a static libgcc. First I reconfed the file source tree so that the latest libtool is used. This worked fine, configure and make succeeded. However, here's the one puzzeling problem I have. I'm unable to build using the -static-libgcc flag. I tried to add it to LDFLAGS, then to CFLAGS, then to both. For some reason this flag is filtered out when gcc gets called to link the shared lib.
To prove that I'm using libtool 2.2.6a: $ grep '^macro_' ../libtool macro_version=2.2.6 macro_revision=1.3012 This is what you find in Makefile: libmagic_la_LDFLAGS = -no-undefined -version-info 1:0:0 [...] libmagic_la_LINK = $(LIBTOOL) --tag=CC $(AM_LIBTOOLFLAGS) \ $(LIBTOOLFLAGS) --mode=link $(CCLD) $(AM_CFLAGS) $(CFLAGS) \ $(libmagic_la_LDFLAGS) $(LDFLAGS) -o $@ And that's what happens when calling make: $ make CFLAGS='-g -O2 -static-libgcc' LDFLAGS=-static-libgcc [...] /bin/sh ../libtool --tag=CC --mode=link gcc -Wall -Wstrict-prototypes -Wmissing-prototypes -Wpointer-arith -Wmissing-declarations -Wredundant-decls -Wnested-externs -Wsign-compare -Wreturn-type -Wswitch -Wshadow -Wcast-qual -Wwrite-strings -Wextra -Wunused-parameter -g -O2 -static-libgcc -no-undefined -version-info 1:0:0 -static-libgcc -o libmagic.la -rpath /usr/lib magic.lo apprentice.lo softmagic.lo ascmagic.lo encoding.lo compress.lo is_tar.lo readelf.lo print.lo fsmagic.lo funcs.lo apptype.lo cdf.lo cdf_time.lo readcdf.lo -lz libtool: link: rm -fr .libs/libmagic.a .libs/libmagic.dll.a .libs/libmagic.la . libs/libmagic.lai libtool: link: gcc -shared .libs/magic.o .libs/apprentice.o .libs/softmagic.o . libs/ascmagic.o .libs/encoding.o .libs/compress.o .libs/is_tar.o .libs/readelf.o .libs/print.o .libs/fsmagic.o .libs/funcs.o .libs/apptype.o .libs/cdf.o .libs/cdf_time.o .libs/readcdf.o -lz -o .libs/cygmagic-1.dll -Wl,--enable-auto-image-base -Xlinker --out-implib -Xlinker .libs/libmagic.dll.a So there's the `-static-libgcc' twice in the libtool comamnd line when called from make. But when libtool calls gcc, nothing's left of it. I understand why CFLAGS is missing, but why did it filter out LDFLAGS as well? And, if that's normal, why, and how do I workaround that?
