Lipo doesn't work

vishwesh · #1 (**permalink**) 08-25-2009

Hi guys,
Am using lipo to merge ppc and i386 version of a static/dylib file based on "file type to load". I am working on Mac OS 10.5.6 and new to shell scripting. Please help me out.

This is my code.

Code:

echo "This file combine ppc and i386 file to form universal library"

echo "source Path: "
read path
echo "source Path1: "
read path1
echo "destination : "
read dest

echo "file type to load"
read exten

for iFile in `find $path -type f -name $exten`
do
    echo $iFile
    iFile1="${path1}${iFile##*/}"
    echo $iFile1
    destFile="${dest}${iFile##*/}"
   lipo -create $iFile $iFile1 -output destFile
done

echo "***   Done   ***"

It's say lipo can't load the file in iFile. I am trying to run lipo command.

Does the file in $iFile exist?

Your script will fail if any of the filenames contain spaces.

Is $exten a complete file name or an extension? Could it contain wildcards?
Code:
find $path -type f -name "*$exten" |
 while read iFile
 do
    echo $iFile
    iFile1=${path1%/}/${iFile##*/}
    echo $iFile1
    destFile="${dest%/}/${iFile##*/}"
   lipo -create "$iFile" "$iFile1" -output destFile
 done

Code:

find $path -type f -name "*$exten" |
 while read iFile
 do
    echo $iFile
    iFile1=${path1%/}/${iFile##*/}
    echo $iFile1
    destFile="${dest%/}/${iFile##*/}"
   lipo -create "$iFile" "$iFile1" -output "$destFile" # changed the last line
 done

I figured out the problem in my script ,
It generated this path
"/sw/lib/ImageMagick-6.5.4/modules-Q16/codersycbcr.a"
which should have been
"/sw/lib/ImageMagick-6.5.4/modules-Q16/coders/ycbcr.a"

Thank you very much. I normally feed exten wildcards "*.a" or "*.dylib". I need to make checks for file existence.

I have faced that problem too. How should I handle white spaces in file paths?

Always quote variables.

Never use:
Code:
for file in $( some_command )
Always pipe the output of the command into a loop instead:
Code:
some_command |
 while read file
 do
   : do whatever with "$file" (not $file)
 done
