通过./configure --host = mingw32后，makefile在制作时崩溃

如何解决通过./configure --host = mingw32后，makefile在制作时崩溃

所有人：情况：具有x86_64-w64-mingw32编译工具链的MacOS我试图从GDB的源代码编译Windows的GDB。但是，在./configure之后，我得到了

/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[2]: *** [all] Error 2

我确定MingW32已完全构建并且具有功能。

我通过HomeBrew安装它，这是我的Makefile中libdir的配置

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

完全不知道如何解决此问题。任何想法？或者，如果您需要更多信息来解决问题，请告诉我。

只需下载GDB的源代码，我认为您可以复制相同的场景。

./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

解决方法

如命令行和错误消息所述，您给libtool的路径不正确。

命令行包含-Llibdir，并且错误消息显示“无法确定'libdir'的绝对目录名称”。

因此，您编写Makefile的目的是按字面意义使用libdir，而不是将其用作变量。将其更改为：

LDFLAGS = -L$(libdir)

或

LDFLAGS = -L${libdir}

括号和花括号之间没有真正的区别，只是不要混淆它们。有用的链接是： The difference between parentheses and curly braces in GNU Make和 What's the difference between parenthesis $() and curly bracket ${} syntax in Makefile?
