Re: Performance gcj & mysql

[ezer <andres dot a at adinet dot com dot uy>]

I run gcj -static-libgcj --main=MysqlConnect -o mysqlconnect
MysqlConnect.java mysql-5.0.8.o

i get:
/usr/bin/ld: cannot find -lgcj
collect2: ld returned 1 exit status

The file libgcj.spec :
%rename startfile startfileorig
*startfile:  %(startfileorig)

%rename lib liborig
*lib: %{static-libgcj:-non_shared} %{s-bc-abi:-lgcj_bc;:-lgcj}
%{static-libgcj:-call_shared} -lm   -lpthread -lrt -lz   -ldl %(libgcc) 
%(liborig)

*jc1: -fhash-synchronization -fno-use-divide-subroutine  -fuse-boehm-gc
-fnon-call-exceptions   -fkeep-inline-functions


I cant find any lgcj file, i found libgcj, even changing the names i get the
same error. Sghould i define a path or add any other file ?
