Re: Mysql and -static--libgcj

[Taufik Chowi <m4g1c14n2000@yahoo.com>]

Dear Ezer,

ok this time i will compile it with my linux server.
it runs on fedora core 4 (quite old) >.<
i cant run using -static-libgcj because my gcj version is too old i think (i am not sure too, because i am quite new with gcj)
# gcj -O2 mysql-connector-java-3.0.17-ga-bin.jar MysqlConnect.java --main=MysqlConnect -static-libgcj
gcj: unrecognized option '-static-libgcj'

instead i used this
# gcj -O2 mysql-connector-java-3.0.17-ga-bin.jar MysqlConnect.java --main=MysqlConnect -findirect-dispatch
# ./a.out
MySQL Connect Example.
Connected to the database
Query executed
Disconnected from database
Execution Time: 0 seconds

delay of 10 seconds?!?!?! are you saying that you've got output "Execution Time: 10 seconds" ?? 
that is crazy.. i have never seen one myself (though my experience with gcj is still a bit short ^^)

here is my gcj --version for linux 
# gcj --version
gcj (GCC) 4.0.0 20050519 (Red Hat 4.0.0-8)

# mysql --version
mysql  Ver 14.7 Distrib 4.1.11, for redhat-linux-gnu (i386)


@first question
my windows version? i can use it without having to install mingw or anything like that
http://www.thisiscool.com/gcc_mingw.htm
i downloaded this one http://static.thisiscool.com/gcc/gcc43-20061204.tar.bz2
extract and use it ^^; no setup (if the memory serves me right)

@second question
hmmm, you know i have read it somewhere , i think it is called native cross compiler or anything like that, it allows you compile a native code for another Operating System
but as you may have guessed, i havent tried it >.< , i think it is kinda like high level stuff or anything like that , since i am really confused reading the article :( (or perhaps it is only me)


Cheers and God Bless,

Chowi

Oh thanks for the time. i also see that for you its run fast. Without linking
static i have a delay in the run of 10 seconds..

Can you tell me 2 thinks. 
1) How do you installed that version in windows.. i tryed with Java Native
compile, Mingw etc.. without succes. 
2) can you generate linux exec with that windows version ? 

I will try to install that version exactly as you indicate to me..
Thanks you a lot....
