PVR texturetool构建阶段 [英] PVR texturetool build phase

问题描述

我目前正在填写 iphone 3d编程手册

本书说要将以下python代码添加到xcode的构建阶段，以运行提供的texturetool。

The book says to add following python code into a build phase in xcode, to run the provided texturetool.

报价

a。将shell保留为/ bin / sh。

a. Leave the shell as /bin/sh.

b。直接在脚本框中输入：

b. Enter this directly into the script box:

BIN=${PLATFORM_DIR}/../iPhoneOS.platform/Developer/usr/bin  
INFILE=${SRCROOT}/Textures/Grid16.png 
OUTFILE=${SRCROOT}/Textures/Grid16.pvr 
${BIN}/texturetool -m -f PVR -e PVRTC $INFILE -o $OUTFILE

c。将其添加到输入文件：

c. Add this to Input Files:

$(SRCROOT)/Textures/Grid16.png

将此项添加到输出文件中：

Add this to Output Files:

$(SRCROOT)/Textures/Grid16.pvr

但是这样做时我收到以下消息。

However when doing this I receive the following message.

Failed to load image
Failed to perform Encode
Command /bin/sh failed with exit code 1

有人能说清楚这个吗？

Could anyone shed a light on this?
