本文使用的ncurses版本為ncurses-5.9.tar.gz 下載地址：https://ftp.gnu.org/gnu/ncurses/ncurses-5.9.tar.gz 1. 將ncurses壓縮包拷貝至Linux主機(jī)或使用wget命令下載并解壓 tar-zxvf ncurses-5.9.tar.gz 2. 解壓后進(jìn)入到ncurses-5.9目錄下 cdncurses-5.9 3. 在ncurses-5.9目錄下創(chuàng)建編譯完成后生成文件位置 mkdiroutput cdoutput mkdirarm-linux 4. 生成Makefile文件 ./configure--target=arm-none-linux-gnueabi --prefix=$PWD/output/arm-linux --enable-termcap --with-shared --without-ada l --target表示編譯器的前綴，需要根據(jù)編譯的不同需求進(jìn)行修改 l --prefix表示編譯完成后生成文件的位置 l --nable-termcap表示 關(guān)鍵代碼使用 termcap(terminalcapabilities)數(shù)據(jù)庫 [自動(dòng)檢測] l --with-shared表示動(dòng)態(tài)編譯 5. 編譯 make 當(dāng)遇到如下報(bào)錯(cuò)時(shí) Makefile:794:recipe for target '../obj_s/lib_gen.o' failed make[1]:*** [../obj_s/lib_gen.o] Error 1 make[1]  eaving directory '.../ncurses-5.9/ncurses'Makefile:109:recipe for target 'all' failed make:*** [all] Error 2 需要進(jìn)入ncurses-5.9/include文件夾，修改 curses.tail 文件下的如下內(nèi)容,將注釋 /* generated */ 去掉 externNCURSES_EXPORT(bool) mouse_trafo(int*, int*, bool); /* generated*/ 6. 安裝 Makeinstall 7. 安裝完成后會在/output/arm-linux目錄下生成庫文件，我們只需將lib目錄下的libncurses.so.5 庫拷貝至開發(fā)板 移植gdb 本文使用的gdb版本為gdb-7.12.tar.gz 下載地址：https://ftp.gnu.org/gnu/gdb/gdb-7.12.tar.gz 1. 將gdb壓縮包拷貝至Linux主機(jī)或使用wget命令下載并解壓 tar-zxvf gdb-7.12.tar.gz 2. 解壓后進(jìn)入到ncurses-5.9目錄下 cdgdb-7.12 3. 生成Makefile文件 ./configure -host=arm-none-linux-gnueabi CC=/home/vanxoak/CodeSourcery/Sourcery_G++_Lite/bin/arm-none-linux-gnueabi-gcc --enable-shared--prefix=$PWD/output/arm-linux --disable-werror --without-x --disable-gdbtk--disable-tui --without-included-regex --without-included-gettextLDFLAGS="-L$PWD/../output/arm-linux/lib"CPPFLASS="-I$PWD/../output/arm-linux/include" l --host=arm-none-linux-gnueabi 用arm-none-linux-gnueabi編譯 l CC為交叉編譯器絕對路徑 l --enable-shared 動(dòng)態(tài)編譯 l prefix=“$PWD/output/arm-linux” 安裝目錄 l --disable-werror 屏蔽werror報(bào)警 l --without-x 取消x windows 支持 l --disable-gdbtk 取消gdbtk l --disable-tui 取消tui 界面 l --without-included-gettext 去掉用于多語言處理的gettext庫 l "LDFLAGS=XXX"指交叉編譯完成的ncurse的lib目錄路徑 l "CPPFLAGS=XXX"指是交叉編譯完成的ncurse的include目錄路徑 4. 編譯 make 5. 安裝 makeinstall 安裝完成后會在.../gdb-7.12/output/arm-linux/bin/目錄下生成gdb可執(zhí)行程序。 移植至HDT3-EVM 開發(fā)板 1. 將libncurses.so.5庫 文件拷貝至/usr/lib目錄下，若/usr目錄下無lib目錄可手動(dòng)創(chuàng)建mkdir lib 2. 將gdb程序拷貝至/bin目錄下 測試調(diào)試 1. 編寫可執(zhí)行測試程序，示例hello.c代碼如下,該代碼執(zhí)行后會打印Hello World。 #include intmain(int argc, char *argv[]) { printf("Hello World\n"); return 0; } 2. 使用交叉編譯器進(jìn)行編譯，需要注意的是，要使用gdb調(diào)試程序，需要在使用交叉編譯器編譯源代碼時(shí)加上 " -g " 參數(shù)保留調(diào)試信息，否則不能使用GDB進(jìn)行調(diào)試且報(bào)如下最后一行所示錯(cuò)誤: /home# gdb hello GNUgdb (GDB) 7.12 Copyright(C) 2016 Free Software Foundation, Inc.
