Makefile 在通过 ./configure --host=mingw32 后制作时崩溃

Question

Everyone: situation: MacOS with x86_64-w64-mingw32 compiling toolchain I tried to compile GDB for Windows from the source code of GDB. But, after ./configure, I got

/bin/sh ./libtool  --tag=CC   --mode=link x86_64-w64-mingw32-gcc -W -Wall -Wstrict-prototypes -Wmissing-prototypes -Wshadow -Wstack-usage=262144 -Wno-format -I./../zlib -Iincludedir -D__USE_MINGW_ACCESS  -release `cat libtool-soversion`  -Llibdir -Wl,--stack,12582912 -o libbfd.la -rpath /usr/local/lib archive.lo archures.lo bfd.lo bfdio.lo bfdwin.lo cache.lo coff-bfd.lo compress.lo corefile.lo elf-properties.lo format.lo hash.lo init.lo libbfd.lo linker.lo merge.lo opncls.lo reloc.lo section.lo simple.lo stab-syms.lo stabs.lo syms.lo targets.lo binary.lo ihex.lo srec.lo tekhex.lo verilog.lo `cat ofiles`   -L./../zlib -lz

make[4]: *** [libbfd.la] Error 1
make[3]: *** [all-recursive] Error 1
make[2]: *** [all] Error 2
make[1]: *** [all-bfd] Error 2

I am sure my MingW32 is fully built and capable.

I install it via HomeBrew And here is the config for libdir in my Makefile

prefix = /usr/local
exec_prefix = ${prefix}
libdir = ${exec_prefix}/lib
LDFLAGS = -Llibdir
...
    "libdir=$(libdir)" \
...

Totally have no idea how to fix this. Any idea? Or if you need some more information to figure it out, just let me know.

And just download the source code of GDB, I think you could duplicate the same scenario.

./libtool: line 5208: cd: libdir: No such file or directory
libtool: link: cannot determine absolute directory name of `libdir'
make[4]: *** [libbfd.la] Error 1
make[3]: *** [all-recursive] Error 1
make[2]: *** [all] Error 2
make[1]: *** [all-bfd] Error 2
make: *** [all] Error 2

Answer 1

As the command line and error message say, you give libtool not the right path.

The command line contains -Llibdir and the error message says "cannot determine absolute directory name of 'libdir'".

So you wrote your Makefile to use libdir literally and not as the variable as it should be. Change it into:

LDFLAGS = -L$(libdir)

or

LDFLAGS = -L${libdir}

There is no real difference between parentheses and braces, just don't mix them up. Helpful links are: The difference between parentheses and curly braces in GNU Make and What's the difference between parenthesis $() and curly bracket ${} syntax in Makefile?
