Hi,
trying to udnesrtand better why I get problems under solaris, I analyze
what is happening (it is not a LIBS problem as I first thought).
The "thread support" program fails:
configure:5552: checking whether objc has thread support
configure:6021: gcc -o conftest -g -O2 -x objective-c -I. -fgnu-runtime
-DGNU_RUNTIME -R/opt/csw/lib -L/opt/csw/lib -R/opt/csw/gcc4/lib
-L/opt/csw/gcc4/lib conftest.c -lobjc -lrt >&5
In file included from conftest.c:8:
config_thread.m:7: warning: incomplete implementation of class
'NXConstantString'
config_thread.m:7: warning: method definition for '-length' not found
config_thread.m:7: warning: method definition for '-cString' not found
configure:6025: $? = 0
configure:6031: ./conftest
ld.so.1: conftest: fatal: libgcc_s.so.1: open failed: No such file or
directory
./configure: line 1: 19713 Killed ./conftest$ac_exeext
This means that the library doesn't get found. I do not want to use
LD_LIBRARY_PATH in this case, -L and -R should be enough.
Oddly, if I compile the test program myself, which would be
config_thread.m I undersrstand
gcc -o conftest -g -O2 -x objective-c -I. -fgnu-runtime
-DGNU_RUNTIME-R/opt/csw/lib -L/opt/csw/lib -R/opt/csw/gcc4/lib
-L/opt/csw/gcc4/lib config_thread.m -lobjc -lrt
I get the same warnings, but can run the program without errors!
$ ldd conftest
libobjc.so.2 => /opt/csw/gcc4/lib/libobjc.so.2
librt.so.1 => /usr/lib/librt.so.1
libgcc_s.so.1 => /opt/csw/gcc4/lib/libgcc_s.so.1
libc.so.1 => /usr/lib/libc.so.1
libaio.so.1 => /usr/lib/libaio.so.1
libdl.so.1 => /usr/lib/libdl.so.1
/usr/platform/SUNW,Ultra-2/lib/libc_psr.so.1
Which is just fine. What's going wrong here?
