在 Mingw 中构建 GDB 错误，配置：错误：未找到增强的 curses 库；禁用 TUI

Question

我尝试在 mingw 中构建 GDB 7.51 以进行跨平台调试，我发现 GDB 有 TUI 作为前端。无论如何，我用 --enable-tui 配置 GDB，然后总是停止并显示错误消息：

配置：错误：找不到增强的curses库；禁用 TUI

我通过谷歌检查了这个问题，然后我从 GNU 下载了 ncurses 源代码

ncurses 5.9

在我的 c:/mingw/msys/1.0/local/ 中构建并安装它

使用以下脚本语句运行 GDB 的配置

export PATH=$PREFIX/gccbinutils/bin/:/usr/local/bin:/usr/bin:/bin:/mingw/bin
export C_INCLUDE_PATH=/usr/local/include:/usr/local/include/ncursest:/usr/include:/c/mingw/include
export CPLUS_INCLUDE_PATH=/usr/local/include:/usr/local/include/ncursest:/usr/include:/c/mingw/include
export LIBRARY_PATH=/usr/local/lib:/usr/lib:/c/mingw/lib
export LD_LIBRARY_PATH=/usr/local/lib:/usr/lib:/c/mingw/lib
export LDFLAGS="-L/usr/local/lib -L/usr/lib -L/c/mingw/lib"
export LIBS="-lncursest"

$BUILD_MIPSGCCDIR/gdb/configure --prefix=$PREFIX/$pkg --target=$TARGET \
                --enable-tui \
                            --enable-curses \
                --enable-sim > $BUILDPATH/$TARGET$pkg.conf1.$argn.log  2>&1

但它不起作用。使用以下消息停止

checking for zlib.h... yes
checking for library containing dlgetmodinfo... no
checking for iconv... yes
checking for iconv declaration... install-shextern size_t iconv (iconv_t cd, char * *inbuf, size_t *inbytesleft, char * *outbuf, size_t *outbytesleft);
checking for library containing waddstr... no
configure: error: no enhanced curses library found; disable TUI
make[1]: *** [configure-gdb] Error 1
make[1]: Leaving directory `/d/tools/buildmipsgcc/build_gdb'
make: *** [all] Error 2 

我已经搜索了 waddstr ，并确定它存在于我的 c:/mingw/msys/1.0/local/lib/libncursest.a 中。

好的，让我们尝试通过提供手写libncurses.la来欺骗Autotools：

# libncurses.la - a libtool library file
# Generated by ltmain.sh (GNU libtool) 2.2.7a
#
# Please DO NOT delete this file!
# It is necessary for linking the library.

# The name that we can dlopen(3).
dlname=''

# Names of this library.
library_names=''

# The name of the static archive.
old_library='libncursest.a'

# Linker flags that can not go in dependency_libs.
inherited_linker_flags=''

# Libraries that this one depends upon.
dependency_libs=''

# Names of additional weak libraries provided by this library
weak_library_names=''

# Version information for libncurses.
current=5
age=0
revision=9

# Is this an already installed library?
installed=yes

# Should we warn about portability when linking against -modules?
shouldnotlink=no

# Files to dlopen/dlpreopen
dlopen=''
dlpreopen=''

# Directory that this library needs to be installed in:
libdir='c:/mingw/msys/1.0/local/lib'

检查我提供的路径和名称，如果它们不同，请更改它们。如果它仍然不起作用，请报告，我会尝试进一步扩展它，直到我们最终修复它。
