Re: libobjc2 still failing tests

[Andreas Fink]

tried that. now ./configure complains.

checking whether objc really works... no
I don't seem to be able to use your Objective-C compiler to produce
working binaries!  Please check your Objective-C compiler installation.
If you are using gcc-3.x make sure that your compiler's libgcc_s and libobjc
can be found by the dynamic linker - usually that requires you to play
with LD_LIBRARY_PATH or /etc/ld.so.conf.
Please refer to your compiler installation instructions for more help.
configure: error: The Objective-C compiler does not work or is not installed 
properly.
