Sub_title: How to tell libtool to respect "-static"?		  
Some programs uses libtool when compiling and linking after you have done the ./configure.

As example I pass the following to build binutils:
Code:

LD="/usr/i386-linux-uclibc/bin/i386-uclibc-ld" CC="/usr/i386-linux-uclibc/bin/i386-uclibc-gcc -static"
CFLAGS="-pipe -Os -mtune=i386 -Wall -D_BSD_SOURCE -D_GNU_SOURCE" LDFLAGS="-static -Wl,--gc-sections,--sort-common,-s" ./configure --prefix=/usr/i386-linux-uclibc/usr --includedir=/usr/i386-linux-uclibc/usr/include --disable-nls --disable-shared --enable-static

...but no matter where I put the "-static" it never turns up in the final linking.

Below a part of the compiling process where the -"static" is present in the first block - but absolutely gone in the second part that actually creates the bin:

Code:

/bin/sh ./libtool --tag=CC --mode=link /usr/i386-linux-uclibc/bin/i386-uclibc-gcc -static -W -Wall -Wstrict-prototypes -Wmissing-prototypes -Werror -pipe -Os -mtune=i386 -Wall -D_BSD_SOURCE -D_GNU_SOURCE  -static -Wl,--gc-sections,--sort-common,-s -L/usr/i386-linux-uclibc/usr/lib -o ar  arparse.o arlex.o ar.o not-ranlib.o arsup.o rename.o binemul.o emul_vanilla.o bucomm.o version.o filemode.o ../bfd/libbfd.la ../libiberty/libiberty.a -lfl  -lz -lm

libtool: link: /usr/i386-linux-uclibc/bin/i386-uclibc-gcc -W -Wall -Wstrict-prototypes -Wmissing-prototypes -Werror -pipe -Os -mtune=i386 -Wall -D_BSD_SOURCE -D_GNU_SOURCE -Wl,--gc-sections -Wl,--sort-common -Wl,-s -o ar arparse.o arlex.o ar.o not-ranlib.o arsup.o rename.o binemul.o emul_vanilla.o bucomm.o version.o filemode.o ../bfd/libbfd.la ../libiberty/libiberty.a -lfl  -lz -lm


By just adding the "-static" to the last command the bin is build static with no problems...Is there a magic flag to be set?

UPDATE: It always help to clear ones mind posting questions...At least for binutils it works if "-Xcompiler -static" is included in LDFLAGS. I will test some other sources were I have the same problem: It works with conky-1.3.0, not with libiconv-1.6.1...

I think you are after the following:

Code:
export LDFLAGS+="-static"

p.s. might be best to stay away from libiconv. I've messed up my system with that before. As best I remember, puppy likes the version that glibc installs.

In my musl static tool chain I wrote a wrapper that use a for arg in $@ case... to look through $@ for -l* and grokked in my link time options there (also replaced -O[0-3] with -Os and added my goodies in ... saved me from a ton of CLI simulated 3rd button click frustration) - just named it gcc after mving gcc to gcc-real

Not at home right now, here is a link to my old one
