Issues while build insight-6.8-1 with --target=spare-elf configuration

使用 insight-6.8-1

% ../insight-6.8-1/configure --target=sparc-elf --prefix=$OPT/sparc-elf-4.7.0 --disable-nls --disable-werror

會出現以下 error messages:

...

查了很久之後，發現是 link erc32 時少了 ncurses 這個 library，也就是少了 -lncurses。
解法：patch insight-6.8-1 source code:
edit ./insight-6.8-1/sim/erc32/Makefile.in

 
Line.25:    SIM_EXTRA_LIBS = $(READLINE_LIB) $(TERMCAP_LIB) -lm -lncurses

重新編譯安裝就OK了!

% ../insight-6.8-1/configure --target=sparc-elf --prefix=$OPT/sparc-elf-4.7.0 --disable-nls --disable-werror
% make
% make install
