SDK version 10.0 and up not noticed by build.sh about cctools-port HOT 7 CLOSED

Works for me without the need to change anything.

What does grep --version print?

from cctools-port.

Hi,

My grep version is 2.25 on ubuntu 16.04. The script detects SDK Version
0.0 if I use the iPhoneSDK10.0.sdk. The build process works of course,
but the macro in wraper.c is not defined correctly. As a result the
min-sdk-version is wrong.

But there is another problem. Apple changed the library format in SDK
version 10. These libraries are only usable with ld64-274. But the
newest version on ld64 that is open source is version 264. Do you have a
workaround for this problem? I have used iPhoneSDK10 which I extracted
from an XCode8.dmg and wrote a little script that changes the XSym-links
to standard symbolic links. With SDK 9.3 everything works perfect. The
script looks like this (feel free to use/include it):

#!/bin/bash

for d in $(find $1 -maxdepth 10 -type d)
do
for f in $(find $d -maxdepth 1 -type f)
do
HEAD=$(head -c 4 "$f")
if [ "$HEAD" == "XSym" ]; then
DEST=$(sed '4q;d' $f)
echo "Dest: $DEST"
rm -r $f
ln -s "$DEST" "$f"
fi
done
done

-mios-version-version=10.0 is wrong?

And no, I don't have a workaround for the linker issues. I will update build.sh once we have an appropriate linker.

Sry if it was a little bit confusing what i wrote. The build.sh script
reads the SDK_Version from the filename. In my case it reads version 0.0 if
i use a sdk10.0.gar.gz ("echo $SDK_VERSION" prints "0.0"). The reason for
that are the 2 digits before the dot in the number. The script expects only
one. The script then passes the wrong $SDK_VERSION as OS_VER_MIN when
wraper.c gets compiled.

This line then sets version "0.0" as the default "iphoneos-version-min":
env(&osmin, "IPHONEOS_DEPLOYMENT_TARGET", OS_VER_MIN);
Of course the problem does not exist if you define
"IPHONEOS_DEPLOYMENT_TARGET" before you build something with the toolchain.

I hope that discribes the problem better.

Oh, I see.

Well, -mios-version-min=10.0 isn't working either...

$ clang -target arm64-apple-darwin11 -mios-version-min=10.0 ~/tmp/test.c
clang-3.9: error: invalid version number in '-miphoneos-version-min=10.0'
$ clang -target arm64-apple-darwin11 -miphoneos-version-min=10.0 ~/tmp/test.c
clang-3.9: error: invalid version number in '-miphoneos-version-min=10.0'

Annoying.

Yes, that's another problem. I am not so familiar with the IOS SDK but i
think that it has to do with the lib file format or the linker version.
ld64-264 is not made for a SDK version higher than 9.3. (it might also not
accept numbers with more then 2 digits in front of the dot)

Yes, ld64-264 does not support the new v2 text stubs. We have to wait until Apple releases the sources for the new lnker. Unfortunately, I have no idea when that will happen.
