Forum OpenACS Q&A: make error in nsjava

Posted by Gilbert Wong on 01/31/01 08:14 PM

I get the following error message when I tried to compile nsjava. I'm on HPUX 11 with jdk 1.17.

gcc -shared nsjava.o log.o set.o pg.o db.o javaevaltcl.o methods.o 
tclcalljava.o -lpthread  -lpthread -L/opt/java/lib -
ljava /home/aol30/sources/aolserver_src/aolserver/tcl8.3.2/unix/libtcl
8.3g.a /home/aol30/sources/aolserver_src/aolserver/thread/libnsthread.
a -o libnsjava.so 
/usr/ccs/bin/ld: Can't find library for -ljava

make[1]: *** [libnsjava.so] Error 1
make[1]: Leaving directory `/home/aol30/sources/nsjava-0.0.9/src'
make: *** [all] Error 1

I checked and these arguments that follow -ljava exist in my path. What is the problem. Thanks. My command line for configure:

./configure --with-aolserver-
src=/home/aol30/sources/aolserver_src/aolserver --prefix=/home/aol30 -
-with-jdk=/opt/java

Well I've never had access to an HP machine, so I've never tested it on HPUX. Does libjava.so actually exist in /opt/java/lib? Most of the java distrubutions that I've worked with actually have libjava.so located in a subdirectory of lib/java. On my solaris machine it's located in the jdk1.1.8/lib/sparc/native_threads directory. On redhat 6.2 it's located in the jdk1.1.8_v1/lib/i686/native_threads directory. Geneerally it follows the pattern of lib/architecture/threads_version (green or native). You should also upgrade your jdk to 1.1.8, as I think that the 1.1.7 version had some threading problems. Make sure that you also get a native threads jdk version.

Dan,

Thanks. It's in: /opt/java/lib/PA_RISC/native_threads

How do I make this location known to the compiler? I'll upgrade to the new version of the JDK before I recompile. Thanks.

set your LD_LIBRARY_PATH environment variable to include the directory where libjava.so is located.

I set the LD_LIBRARY_PATH variable and it didn't carry through so I edited the Makefile.global and changed it there. I just noticed that the files in the native_threads directory uses .sl instead of the .so extension. The compiler comes back with this error:

gcc -shared nsjava.o log.o set.o pg.o db.o javaevaltcl.o methods.o tclcalljava.o -lpthread  
-lpthread -L/opt/java/lib/PA_RISC/native_threads

make[1]: *** [libnsjava.so] Error 1
make[1]: Leaving directory `/home/aol30/sources/nsjava-0.0.9/src'

Any ideas? I got this problem before and I can't remember how I fixed it. Thanks. Gilbert

Well this is good. With your help, we can get nsjava to compile on hpux. It sounds like the configure script is not detecting the hpux platform correctly. Could you run configure again and post the output?

The -L option gets set to /opt/java/lib every time I run configure even though I set the LD_LIBRARY_PATH variable. I have to hack the makefile to change it. Thanks.
