Re: not-so-basic gcc question [was very basic gcc question]

For those who are interested:

In any case I had a sudden revelation this morning:  the code compiled fine, but didn't link.  For C++ code, these are equivalent (as far as I can tell):

g++ foo.cc
gcc -xc++ -lstdc++ foo.cc


As for the Java, gcc -xjava -c Foo.java will compile the Java to a .o object file.  I found that there is a program,   /usr/lib/gcc-lib/i386-redhat-linux/2.96/jvgenmain , that takes a class name as an argument and writes C code for main to stdout.  this main can then be compiled and linked with the other object files.

gcj --main=Foo Foo.java

is the same as

gcc -xjava -c Foo.java 
 /usr/lib/gcc-lib/i386-redhat-linux/2.96/jvgenmain Foo > main.c
gcc -lgcj -lgcjgc -lpthread -lzgcj main.c Foo.o 


The following also seem to be equivalent:

gcc -xjava -c Foo.java
gcj -c Foo.java

I don't think you can create .class file using the gcc command.
