Compiling gcc-4.2-iphone fails with gcc-4.4 and iPhone OS 3.1.2 #23

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
I am attempting to build the toolchain using iPhone OS 3.1.2 and gcc-4.4.
Everything works fine (that's relative, I had to add a few includes) until
gcc-4.2-iphone which fails with the following error:

{{{
ld: library not found for -lc
collect2: ld returned 1 exit status
make[3]: *** [libgcc_s.dylib] Error 1
make[3]: Leaving directory
`/home/jamal/devel/iphone/toolchain/toolchain/bld/gcc-4.2-iphone/gcc'

make[1]: *** [all-gcc] Error 2
make[1]: Leaving directory
`/home/jamal/devel/iphone/toolchain/toolchain/bld/gcc-4.2-iphone'

Here's some info on my setup:

Thanks for your help.

Guess the issue tracker doesn't follow the wiki styles, sorry!

I resolved *this* issue, although I got stuck somewhere else. Basically, the 
script
wasn't copying the Leopard SDK correctly. I'm not exactly sure why but all I 
did was
manually copy the usr/lib/ from within the MacOSX10.5.sdk to the sys directory. 

To do this, from the trunk directory (where toolchain.sh is):

cp -r sdks/MacOSX10.5.sdk/usr/lib/ toolchain/sys/usr/lib/

I get same errors after cp usr/lib to the system directory, attaching my 
make.log file.
There are many "/./" in the path names, so I guess maybe the changed we make to
toolchain.sh cases these errors.

Hi,

I did the cp -r suggested by jfanaian, but it wasn't enough. I finally got it 
to go
further after I copied everything from MacOSX10.5.sdk into toolchain/sys. After 
that,
I got into another issue: seems I had replaced some iPhone files by MacOSX 
files. So
I was getting linking errors, especially on libc.dylib.
libc.dylib points to libSystem.B.dylib so I replaced the libSystem.B files I 
had with
the ones from iPhoneOS3.1.2.sdk. Then the toolchain was built correctly.
Afterwards, when trying to build the Hellotoolchain app, it couldn't find 
UIKit. So I
copied that from the iPhoneOS3.1.2.sdk, and then did the same for 
CoreFoundation and
Foundation.
Now the Hellotoolchain.app is on my iPhone. But I'm pretty sure that if I use 
other
Frameworks I'll have problems.
I'll try to start from the beginning and copy the files from the SDKs and the
firmware manually. I think I should do it in these order: iPhone framework, than
iPhone SDK and finally MacOSX SDK without replacing files.

Hope all this will help you guys.

fsaftoiu, no need to copy or link anything just don't let the toolchain.sh 
clean the
build after you finish and then add this to your LDFLAGS:

LDFLAGS=  -isysroot ../../sdks/iPhoneOS3.1.2.sdk/ -lobjc
