Re: [Ant-contrib-developers] Another round

Hi Curt,

i think we are mailing in a circle now :-)

Probably you need to test your code snippets locally
as our development cycle (you code - i test - send email
- you code ...) is a bit inefficient.

The current result is for example:

gcc -Wl,-L /opt/local/mico/lib -Wl,-lmico2.3.7 -Wl,-lmicocoss2.3.7 
-Wl,-L /opt/local/xerces-c-src1_7_0/lib -Wl,-lxerces-c1_7_0 -Wl,-L 
/home/xmlblast/xmlBlaster/lib -Wl,-lxmlBlasterClient -Wl,-L /lib 
-Wl,-ldl -o TestGet ../../../build/obj/TestGet.o

we don't need to pass -L or -l with a -WL in front
just -L or -l is correct.

This is how a correct output looks like imho:
--------------------------------------------------------------
g++ -g -Wall
     -Wl,-rpath=/home/xy/lib -L/home/xy/lib -lxmlBlasterClient
     -lld -lstdc++
     TestGet.o -o TestGet
--------------------------------------------------------------

The '-L ' is not necessary, since i just found out that
-L/bla is OK as well.

The -rpath needs the -Wl

The other options don't want it.

The libs libld.so and libstdc++.so are in well known locations
where as libxmlBlasterClient.so needs the -L and -Wl,-rpath options
to be found (without LD_LIBRARY_PATH).

No, see above.

Resolved, i just found out that -L works without ' ' as well!

thanks
