does anybody understand what happens here?<div>when my script reachs the <b>./configure</b> line... it gets the error:</div><div><div><font face="courier new, monospace">/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc is unable to create an executable file.</font></div>
<div><font face="courier new, monospace">C compiler test failed.</font></div></div><div><br></div><div>but if I type "<b>echo</b>" before ./configure, I see this big command line here:</div><div><font face="courier new, monospace">./configure --cc=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc --as='/usr/local/bin/<a href="http://gas-preprocessor.pl" target="_blank">gas-preprocessor.pl</a> /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc' --sysroot=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.1.sdk --arch=arm --cpu=arm1176jzf-s --extra-cflags='-arch armv6' --extra-ldflags='-arch armv6 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.1.sdk' --prefix=compiled/armv6 --enable-cross-compile --target-os=darwin --enable-nonfree --enable-gpl --disable-armv5te --disable-swscale-alpha --disable-doc --disable-ffmpeg --disable-ffplay --disable-ffprobe --disable-ffserver --disable-asm --disable-debug</font></div>
<div><br></div><div>If I copy/paste this big line in my shell and execute, the configure <b><font color="#009900">works pretty perfect</font></b>. But why it <b><font color="#ff0000">doesn't work on the script</font></b>? What is the difference between these 2 scenarios?<br>
