T113 tina linux 移植 gpsp 模拟器

[hsinyuwang]

gpsp 依赖 SDL 和 SDL_TTF

• SDL 1.2.5 的移植可以看这篇文章 d1s移植sdl1-2-15版本，makefile中需要关掉 directfb 和 tslib

CONFIGURE_ARGS += \
		--enable-static=no \
		--disable-video-directfb \
		--enable-input-tslib=no \

同时在 menuconfig 中也关掉 directfb

• SDL_TTF 可以在 openwrt 的 package 中找到 https://github.com/robbie-cao/openwrt-packages-kyak 直接将 libsdl-ttf 复制到 tina linux 的 package/libs 目录下，这个 makefile 里面是 2.0.9 的版本，可以修改到 2.0.11 ，对应修改 md5sum 为 61e29bd9da8d245bc2471d1b2ce591aa

PKG_NAME:=libsdl-ttf
PKG_VERSION:=2.0.11
PKG_RELEASE:=2

PKG_SOURCE:=SDL_ttf-$(PKG_VERSION).tar.gz
PKG_SOURCE_URL:=http://www.libsdl.org/projects/SDL_ttf/release/
PKG_MD5SUM:=61e29bd9da8d245bc2471d1b2ce591aa
PKG_BUILD_DIR:=$(COMPILE_DIR)/SDL_ttf-$(PKG_VERSION)

编译好之后 开始编译 gpsp

• 修改 CFLAGS 添加头文件路径

-I/home/hsinyuwang/t113/tina-d1-h/out/t113-nezha/staging_dir/target/usr/include/SDL -I/home/hsinyuwang/t113/tina-d1-h/out/t113-nezha/staging_dir/target/usr/include

• 修改 LDFLAGS 添加库文件路径

-L/home/hsinyuwang/t113/tina-d1-h/out/t113-nezha/staging_dir/target/usr/lib

• 修改 LIBS 添加需要链接的库文件

-lfreetype -lbz2

完整的 makefile

TARGET  = gpsp
CC      = arm-openwrt-linux-gnueabi-gcc-6.4.1
VPATH   = .. ../arm
OBJS    = main.o cpu.o memory.o video.o input.o sound.o cheats.o zip.o  arm_stub.o  warm.o cpu_threaded.o video_blend.o sha1.o imageio.o gui_xboy.o #gui.o
CFLAGS  = -DARM_ARCH -DPC_BUILD -march=armv7-a -mtune=cortex-a7 -mfloat-abi=hard -mfpu=neon -ffast-math -Ofast -I/home/hsinyuwang/t113/tina-d1-h/out/t113-nezha/staging_dir/target/usr/include/SDL -I/home/hsinyuwang/t113/tina-d1-h/out/t113-nezha/staging_dir/target/usr/include
LDFLAGS = -L/home/hsinyuwang/t113/tina-d1-h/out/t113-nezha/staging_dir/target/usr/lib
LIBS    = -lSDL -lSDL_ttf -lz -lpng -lfreetype -lbz2

all: $(TARGET)

$(TARGET): $(OBJS)
	$(CC) $(LDFLAGS) $(OBJS) $(LIBS) -o $(TARGET)

%.o: %.S
	$(CC) $(CFLAGS) -c -o $@ $<

clean:
	rm -f *.o $(TARGET)

导入环境变量后编译

export PATH=$PATH:/home/hsinyuwang/t113/tina-d1-h/out/t113-nezha/staging_dir/toolchain/bin/
export STAGING_DIR=/home/hsinyuwang/t113/tina-d1-h/out/t113-nezha/staging_dir/

OK了

因为 t113 的屏幕驱动没有调，所以还没办法验证
完整的 gpsp 代码 https://github.com/hsinyuwang/gpsp 切换到 t113 分支
过程遇到了很多问题，感谢司徒大佬指点！

补充：sdl_ttf 的 makefile 需要把 DEPENDS:=+libsdl 改成 DEPENDS:=+sdl +libfreetype

define Package/libsdl-ttf/description
  SDL_ttf is a TrueType font rendering library that is used with the SDL library, and almost as portable. It depends on freetype2 to handle the TrueType font data. It allows a programmer to use multiple TrueType fonts without having to code a font rendering routine themselves. With the power of outline fonts and antialiasing, high quality text output can be obtained without much effort.

@hsinyuwang 请问 GPSP 源码从哪里下载呢？

@hsinyuwang
请问一下 gba_bios.bin要去哪里找
编译完没出现

root@imx6ull14x14evk:/tmp# ./gpsp

Sorry, but gpSP requires a Gameboy Advance BIOS
image to run correctly. Make sure to get an
authentic one, it'll be exactly 16384 bytes large
and should have the following md5sum value:

a860e8c0b6d573d191e4ec7db1b1e4f6

When you do get it name it gba_bios.bin and put it
in the same directory as gpSP.

Press any button to exit.
