[Bug libgcj/20265] New: Unable to generate a shared library from a jar file using gcj v4.0

[bparker at ilstechnology dot com]

I am using version 4.0 of gcj and when trying to convert a jar to a shared 
library I get the following:

[EMAIL PROTECTED] WMQ]$ gcj -I /home/acuser/gcj/WMQ  -shared com.ibm.mq.jar  -o 
mq-
shared.so
com/ibm/mq/BindingsConnectionRequestInfo.java:0: error: cannot find file for 
class javax.resource.spi.ConnectionRequestInfo
com/ibm/mq/BindingsConnectionRequestInfo.java:0: error: cannot find file for 
class javax.resource.spi.ConnectionRequestInfo
com/ibm/mq/MQConnectionRequestInfo.java:0: error: cannot find file for class 
javax.resource.spi.ConnectionRequestInfo
com/ibm/mq/MQConnectionRequestInfo.java:0: confused by earlier errors, bailing 
out

The ConnectionRequestInfo.class file is in another jar in the same directory as 
the com.ibm.mq.jar file. Which is the same directory that I am running gcj out 
of. I got the same errors when I was using version 3.2 but I got around it by 
adding the -I parameter. But now using version 4.0 the errors are back. Am I 
missing a parameter? Help.

[Bug libgcj/20266] New: Using v4 of gcj I am unable to build an executable from shared libraries

[bparker at ilstechnology dot com]

Using gcj verion 4 running on red Hat Enterprise Linux ES release 3 I tried to 
create a executable using shared libraries I had previously created. I got the 
following results:

[EMAIL PROTECTED] WMQ]$ gcj --main=mqTester -o mqTester mqTester.java -L. -
lconnector-shared -lmq-shared
mqTester.java:18: error: Can't find default package ΓÇÿcom.ibm.mqΓÇÖ.

mqTester.java:197: error: Type ΓÇÿMQExceptionΓÇÖ not found in the

of the local variable ΓÇÿmqeΓÇÖ.
} catch (MQException mqe ) {
^
7 errors

The classes MQQueueManager, MQException, MQPutMessageOptions, etc. referenced 
above all reside in the mq-shared shared library, which was built from a jar 
file and resides in the /home/acuser/gcj/WMQ directory.

I am running this from the /home/acuser/gcj/WMQ directory. My classpath is set 
to the folloing: 
[EMAIL PROTECTED] WMQ]$ echo $CLASSPATH
/home/acuser/gcj/WMQ:.

My path is set to the following:
[EMAIL PROTECTED] WMQ]$ echo $PATH
/usr/local/bin:/bin:/usr/bin:/home/acuser/gcj/WMQ:/home/acuser/bin


FYI..the main program compiles and run successfully on the same box if I do the 
folowing from the command line

[EMAIL PROTECTED] WMQ]$java -cp com.ibm.mq.jar:connector.jar: mqTester -QMgr 
AIX.QUEUE.MANAGER -QName AIX.DATA.QUEUE -hostname 192.168.1.36 -channel 
CHANNEL1 -port 1416
