I have not tried generating .h files for these, and I havent even tried linking java together with c++, My main objective is really just to compile prebuilt java applications into native binary using gcj. In generating ".class" files, you could use "gcj -C" in the same way you use "javac" from sun's jdk, "gij" in the same way you could use "java" from sun jdk, Here is an example: $gcj -C Hello.java that would generate Hello.class in the same you do as(in suns jdk) $javac Hello.java To run, just use $gij Hello in the same(suns jdk) $java Hello Regards, ivanceras On Fri, Jun 5, 2009 at 6:39 PM, Vaijayanthi Mala Suresh<vaijayanthimalas@gmail.com> wrote: > Hi ivanceras, > > Thanks for your help. > > Can you please let me know i can generate .class files as I have > native methods defined in many of these java files for which > I need to generate the .h files as well. > > Thanks > Mala > > On Fri, Jun 5, 2009 at 2:26 PM, jovansonlee cesar<ivanceras@gmail.com> wrote: >> Hi Vaijayanthi Mala Suresh, >> >> Here is my little example: >> http://ivanceras.blogspot.com/2009/04/gcj-vs-jvm-benchmark.html >> >> $gcj -c -g -O Test.java >> $gcj --main=Test -o Test.bin Test.o >> $./Test.bin >> >> and here's how you would compile jar library file(ie. postgresql jdbc >> driver) and link it to your main class >> http://ivanceras.blogspot.com/2009/05/gcc-vs-jvm-benchmark-2.html >> >> Compiling, Linking and Running in GCJ: >> >> compile the PostgreSQL jdbc driver >> $gcj -c -g -O postgresql-8.4dev-700.jdbc3.jar >> This will create the native binary file "postgresql-8.4dev-700.jdbc3.o" >> >> compile the Test >> $gcj -c -g -O TestDb.java >> This will create the native binay file "TestDb.o" >> >> do the linking >> $gcj --main=TestDb -o TestDb.bin postgresql-8.4dev-700.jdbc3.o TestDb.o >> This will create the executable file: "TestDb.bin" >> >> execute >> $./TestDb.bin >> >> Please visit the blog for more details :) >> >> Regards, >> ivanceras >> >> (PS: have to resend, mailist don't seem to accept html text) >> >> On Fri, Jun 5, 2009 at 3:39 PM, Vaijayanthi Mala Suresh >> <vaijayanthimalas@gmail.com> wrote: >>> >>> Hi, >>> >>> I have a several packages of java files which I need to compile with >>> gcj to generate .class and .o files. >>> >>> Can anyone help me please. >>> >>> Thanks >>> Mala >> > ^ permalink raw reply [flat|nested] 7+ messages in thread
